Setting financial defaults

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

Financial defaults set here will be automatically applied to your projects so you do not have to input them each time. These defaults can be overridden on a per-project basis. 

For standard Easy PV users, you can set up financial defaults in My Account > Preferences > Financial. For Pro teams wishing to set team defaults, these can be found in Pro account settings > Financial. If you are a member of a Pro team, you may not be able to set these defaults as they will be configured by your team owner or admins.

Main settings
Tariffs 

Here you can set default tariffs for the Easy PV and (for UK) MCS consumption calculations. They can be indexed to inflation, above inflation, fixed or none. 

For more detail on how to create and edit these tariffs, have a look at our tariffs guide

Automatic pricing calculator

This is where you can tailor the financial settings so you do not have to make significant adjustments on each project. You can set up rules based on look-up tables or a set markup and then set costs for the delivery and installation and optionally scaffolding, roofing, electrical, travel costs and any additional services you provide. 

A full guide on how to set this up can be found here in the automatic pricing guide

Manual pricing markup 

If you are not using the pricing calculator, you can set a default markup which is applied to the cost of goods.

Tax settings

Here you can set defaults for the tax rate for material and services and select whether the customer will be able to reclaim the tax. Business customers can usually reclaim tax paid on an installation, but domestic customers typically can't reclaim tax. Tax rates may be different for domestic and business customers. 

Running cost rules 

Add lines for costs you expect to be incurred in the future. You can choose whether costs are applied on an annual basis (for example a maintenance contract) or as one-off costs (for example an inverter replacement).

Saving rules 

Create savings rules which can be used in the financial task. You can set them to appear on every project or only be applied if a given accessory is present and can add savings based on a percentage of bills, percentage of annual generation, fixed monetary amount or a saving in kWh each year.

Setting up your account

Setting up your Automatic Pricing Calculator

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

With Easy PV you can configure pricing rules to automatically calculate project prices. Rather than having to amend and change your service costs on each project, you can spend time setting up your pricing rules so the automatic pricing calculator will do it for you. 

Pricing settings can be accessed via Account settings  > Financial > Change pricing settings or if you are part of a Pro team, the owner/admin can do this via Pro Account settings  > Financial > Change pricing settings.

To turn off automatic pricing click on the use pricing calculator toggle. You can also switch between automatic pricing and manual pricing on a per-project basis via the financial task. 

Configuring for your project

You can set material pricing based on the cost of materials plus a markup (best for complex pricing depending on the number of panels, roof dimensions, travel distance, etc.) or based on custom lookup tables (ideal for simpler pricing using only a few panels/inverters combinations).

On top of the cost of materials, you can set up additional charges for the delivery and installation. The installation cost can be further specified with costs for scaffolding, electrical, roof type, and travel to the site.

  1. Choose if you use a markup or lookup table for calculating the cost of materials.

  2. Tick the box for each additional cost you want to include in your pricing (information on configuring each of these is below).

  3. Choose the format in which you want to display the price of goods in the quote.

Lookup tables or markup 
Option 1: Lookup tables

When you have chosen lookup tables on the first price settings page, before clicking next you can also choose to use a markup-based pricing for any designs that don’t match one of the lookup tables you have entered. 

When you click Next, you can then create your lookup tables for different combinations of solar panels, inverters and batteries. Different costs can be specified within each combination for different numbers of panels.

image.png

Lookup tables are most useful if you install just a few different system combinations (i.e always use Trina with Growatt). If you need more than a few lookup tables, it’s probably more efficient to use the ‘markup’ method.

Option 2: Cost of materials plus a markup 

When Markup has been chosen on the first pop up screen, clicking Next will bring you through to the following page where you can input levels of markup for different sizes of projects. 

image.png

You will also notice a section for Consumables and ancillaries. This includes items not included with the PV kit such as zip ties. Throughout this calculator, you will be able to click +Add Row to create rules and changes to your costs depending on project size or travel distance. 

Next continue through each of the steps to set up rules for your services. Click into each of the sections below for detailed instructions.
Configure required costs 
Delivery

You can determine an appropriate default delivery cost and hazardous surcharge fee (when a battery is added to a project) for various project sizes.

image.png

Installation

Here you can add a base installation cost which may cover all of your services (scaffolding, electrical, etc.) or you can set those up separately. You can also choose what text is displayed on the quote for this line item. 

image.png

Configure optional costs
Scaffolding

In this section, you can set a base scaffolding fee and an extra cost for each additional roof. You can also set parameters for max length and height and have an additional charge or multiplier if those parameters are exceeded. 

image.png

Please note that some elements of the pricing calculator will only work for projects created with the 3D design mode. If you use one of the other design modes scaffolding costs may not be calculated.
Roofing

For roofing , you can add a base cost and fee for each additional roof. You can set additional charge per solar panel depending on the roof type. Finally, you can add a cost for per each extra such as in-roof panel, optimiser, etc.  

image.png

Electrical

Similarly, you can add a base electrical cost, additional fees for the installation of different inverters, and a cost for the installation of a battery.

image.png

Travel

You can add costs for travel to site based on the distance (which Easy PV automatically calculates if you have input the project location and your company location!). You can also set up a travel cost multiplier for larger systems. 

image.png

Configure other costs

If there are costs you want to include on every project that you can't factor into any of the above sections then you can do so by adding a new accessory custom component.  

Accessories and extras

Accessories and extras can be added by creating a new component in the Edit Accessories section of Components. When adding an accessory or extra component, you can add an installation charge as well, and configure whether you want the price applied to the extra to be displayed in the quote as a line item, or grouped into the materials costs.

To do this navigate to My components > Accessories and then:

  1. Create a new accessory, name it with whatever additional service you want to include 
  2. Do not fill in the 'price' box 
  3. If you would like the item or service to be included on all projects, then select the second option 'Include by default' in the rules. If you do not want to include by default you will be able to select it on a per-project basis in the electrical task. 
  4. Then scroll to bottom of 'rules' and check the following options:
    • Add installation cost - this is where you fill in the price and name of the item or service 

      Screenshot from 2024-11-22 14-52-14.png

    • Control quote display - this is where you can decide how it will display on the quote  

      Screenshot from 2024-11-22 14-52-49.png
  5. You can also have a look at the other rules available on accessories and decide whether you would like to include or not include the item (for example, only include with specific inverters).

Performance task defaults

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

The Performance task can be streamlined by configuring your settings in My account > PreferencesPerformance. Here you have the option to configure whether you want panel allocation and the generation of sunpath diagrams and shading factors to be automated.

Panel allocation

Choose between:

Sunpaths

With 3D and Magic design mode, by modelling any nearby obstructions, Easy PV can automatically calculate any shading losses. Here you can choose whether you want Easy PV to automatically calculate shading based on the terrain and 3D buildings or whether you want this to be excluded so you can set the shading manually.

UK site only

The following settings are only available on the UK version of Easy PV (easy-pv.co.uk).

Mode: Choose between MCS and NREL methods to calculate the total annual generation of the system.

MCS Self Consumption: Choose whether you want to:

Quick Roof

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

This guide explores Easy PV’s design mode “Quick Roof”, and the various tools at your disposal to create precise and complex roof designs.

Edit via the corner points

Click anywhere on the roof to get the editing points to show. Clicking and dragging the white corner points allows you to resize your roof.

Selecting one of the corner points will bring up three options:

image.png   Fixed corner angle: the angle of the corner will stay fixed when you drag it (see below, left).

image.png   Free corner angle (default): corners move freely when dragged (see below, right). 

image.png   Delete corner: this removes the corner, e.g. it would turn a rectangular roof into a triangle.

image.pngimage.png

Edit roof dimensions: clicking on the white corners brings up the dimensions for the adjacent sides. If you click on this value, you will be able to input the precise dimensions for that side. 

image.png

Add corners by dragging the orange points

Clicking and dragging the orange points allows you to add extra roof edges to the roof. This is great for creating unusually shaped roofs.

image.png     image.png

Edit via the white rectangles

The white rectangle icons on each side allow you to amend the width/height of the roof.

If you click on the white rectangle, it gives you two options: 

image.png  Elongates the whole roof (see below, left)

image.png  Creates a new set of corners: drags the selected roof edge out, staying parallel to the adjacent white points (see below, right)

Irregular Building Tool in 3D design mode

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

The irregular building tool allows you to create unusual roof shapes in the 3D design mode. It’s perfect for complex buildings and large commercial projects.

Step 1: Inserting the roof

Scroll down in the left-hand toolbar and select the irregular building tool in the miscellaneous section. In this example, we will plot the highlighted roof below. We will do so by plotting out each roof face one at a time.

image.pngimage.png

Step 2: Resizing the roof

First, we will create the west-facing roof. Start by adding a new irregular roof and then drag each of the pink corner controls to the four corners of the roof face. If you accidentally create too many corners, click on the respective pink corner control and press the bin icon to delete them.

image.png

Resizing options if you click on one of the pink corner controls, it will bring up three options:

Input precise roof dimensions Clicking on the white corners also brings up the dimensions for the adjacent sides. If you click on this value, you can input the precise dimensions for that side.

image.png

Step 3: Editing the slope direction

The direction that the roof slopes is indicated by the arrow on the roof.

To edit the slope direction, drag the blue dot (it can be a little hard to spot at first!). You will see that this
moves the arrow.image.png

It is useful to watch how the slope changes in the Elevations box. It’s likely you’ll want the gutter line to be completely horizontal. When it becomes horizontal, it will snap into place in the Elevations box.

image.png

Step 4: Edit roof details

In the same way as the normal 3D design mode, edit the roof height, pitch, material, and eaves depth using the boxes shown below.

image.png

Step 5: Creating a triangular roof

You now need to create the other three roofs. To create the triangular roofs, insert a new irregular roof and drag the x3 pink-white points to their respective corners. Then simply delete the remaining corner to turn it into a triangle.

image.pngimage.pngimage.png

The finished result!

After inserting all four roofs and amending the various roof slopes and heights, we have designed a complete irregular building.

Selecting a roof in 3D design mode

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

When you finish designing your property in the buildings task, click next and this menu will appear. 

Here you will see each roof rated on a scale of poor to good based on our how suitable Easy PV thinks the roof will be for solar. This is based on the size of the roof as well and how much shade will be on the roof based on its pitch and orientation. 

image.png

Selecting your roof 

This menu shows all the roofs on the map (when no property boundary is present). Easy PV will automatically select whichever roofs it thinks are the best. These can be deselected using the check box on the right. If you place your cursor over the roofs, they will also show up in bold so you can easily identify which roof you need. 

image.png

When there is a property boundary, only the roofs within that boundary will show is this menu for maximum ease of selection!

Performance and self-consumption


Performance and self-consumption

Performance task

This guide applies to easy-pv.ie and easy-pv.co.uk versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

The performance task uses the system data, location and shading information to estimate the annual output of the system. This is then used in self-consumption calculations to estimate how much of what is generated will be used directly, used to charge a battery or exported to the grid, which is needed to estimate the financial benefits of the system. 

Getting started with the Performance task

You can access the Performance task via the 'Tasks' drop-down menu or from the task list to the left on the project overview page. 

When the Performance task first opens, you'll be shown a popup that lets you configure the settings you want to use. You can use the left hand navigation to choose the settings you want to edit. More information on each of the settings is available below.

image.png

When you have finished configuring these inputs, click Done.


Navigating the performance task 

The right hand sidebar contains options to switch between the Sunpaths and the Performance results:

View and edit Sunpaths

The sunpath diagrams maps the path of the sun across the sky at different hours in the day for different months of the year. For each point on the sunpath diagram, Easy PV calculates the amount of solar radiation reaching the panels from direct and diffuse radiation. For shaded regions, where direct radiation is radiation is fully blocked, the system calculates how much diffuse radiation still reaches the panels. The shading factor is the proportion of solar radiation that reaches the panels after accounting for these shading losses.  

image.png

Automating with 3D

If designing in 3D or magic design mode, the shading can be calculated automatically, provided any trees or obstructions have been modeled. Otherwise, you will need to manually draw on the sunpath diagram what shade is on the panels at different points in the year. Click between the inputs to expand the sunpath diagrams for each inverter. 

Navigating between inverters and inputs

On the right you will see each of your inverters, when selecting between them you will see each input or shading group for that inverter on the left. Once each sunpath diagram has been calculated, a green tick will show on the inverter. 


View the Performance results  

These results will depend on which version of Easy PV you are using, below you can expand for information on each version:

MCS performance and self-consumption results

The performance estimate calculated here is based on the method detailed in Appendix B of MIS 3002: The Solar PV Standard (Installation). See the end of this section for more information on the methodology used for the self-consumption calculation.  

The MCS performance report can be accessed from the forms (and then reports) drop down menu. 

A. Installation data 
This section details the installed capacity, orientation of the system, inclination of the system and the location. These inputs can be adjusted by clicking the pen icon in the top right or by adjusting the panels on the system. 

B. Calculations
Using the installation data and the shading factor, an estimated annual output is calculated. To adjust the shading factor, navigate to the sunpaths diagrams tab. 

C. Estimated PV self-consumption – PV only
The estimated self-consumption for the system with PV only is taken from the MCS lookup tables, depending on the values above and those input in the task. Click the pen icon to adjust these inputs. 

D. Estimated PV self-consumption – with EESS
The estimated self-consumption for the system with PV and battery storage is taken from the MCS lookup tables. This section will not show if there is no battery storage, navigate to the inverter task to include battery storage.

E. Additional benefits from PV and EESS
If additional consumption is anticipated or some of the battery capacity is reserved for ancillary services, that will be detailed here. This section will not show if that is not the case, to edit those inputs click the pen icon in the top right and navigate to the self-consumption tab. 

Screenshot_25-4-2025_14556_staging.easy-pv.co.uk.JPG

NREL performance results

Section details the installed capacity, orientation of the system, inclination of the system and the location. These inputs can be adjusted by clicking the pen icon in the top right. 

In section B, the data in section A is used to estimate the output per kWp for the unshaded array using the NREL's PVWatts calculator. The percentage of output lost from shade is then subtracted from this value. This is then multiplied by the kWp of the input to calculate the estimated generation per input. To adjust the percentage lost, navigate to the sunpaths tab. 


Edit the Performance task inputs 

Certain inputs are required for the performance estimate to be calculated. Designing in 3D and configuring your settings to automate panel allocation and sunpath diagram calculations will streamline much of this task. 

Location

If not already input when creating the project, you will need to set the location. This is necessary for performance calculations since where in the world the system is located determines how much sunlight it will get. If there is no postcode for the location of your system, choose the most local one you can find. 

This section may show as ticked and completed already if this information can be pulled from the start of the project. 

Roofs

If you are creating a flat roof system or using quick roof mode, you will also need to input pitch and orientation. Both this and the location data are used to determine the output of the system.  

This section may show as ticked and completed already if the pitch and orientation can be populated from earlier in the project. 

Panel allocation

This section will depend on how you have configured your settings.

There are some cases where auto-stringing will not work and manual allocation will be required. Further information about manual panel allocation can be found here

Self-consumption calculation

A self-consumption model is available through the Consumption Task. For UK users, this can be provided to customers in addition to the MCS calculation, which is completed here in the performance task. 

MCS self-consumption calculation

This process follows MCS guidelines defined in The Battery Standard MIS 3012 ISSUE 0.1 to predict self-consumption of the generated PV electricity. UK companies installing under MCS will need to provide this calculation when it can be used. 

Annual electricity consumption of the property

The lookup tables for this calculation only permit values between 1500kWh and 6000kWh. Use the consumption task for more detailed consumption calculations or for values that fall outside this range.

For the most accurate results use a value from past electricity bills. Where possible, consumption data should be taken before the installation of electric heating / hot water or electric vehicle charging.

Occupancy archetype

Properties that are occupied during the day will typically consume more PV-generated electricity directly. Properties that are empty during the day may benefit more from battery storage that can store PV-generated electricity for later use.

Proportion of battery used for ancillary services such as backup power or arbitrage

If there is a battery on the project, this question will appear. If the entire battery capacity to be used to increase self-consumption, this value will be 0%.

The lookup tables for this calculation only permit that the usable capacity is less than 15.1kWh, in this case use the consumption task for more detailed consumption calculations. 

Is additional self-consumption anticipated?

The MCS calculation does not account for consumption arising from "non-typical domestic loads" such as electric space heating, swimming pools, heat pumps, electricity power diverters, electric water heating and electric vehicles.

You can enter any figure here, but the calculation assumes that a maximum of 95% of the generated electricity is available for self-consumption so the value in the results table will be capped to the remaining available generation capacity.

Performance and self-consumption

Manual panel allocation

Manually allocating panels is slightly different depending on whether the panels are optimised or not. All panels connected to an input must be within a certain pitch and orientation threshold and panels incompatible with the selected string will be unselectable. In this case you may need to add optimisers. 

Without optimisers 
  1. Select the current roof and inverter input from the lists on the left.
  2. Click or drag over panels to allocate them to an inverter input. 
  3. Once all inverter inputs have the correct number of panels, all inputs will be in green and a tick will show at the top. Below all your inverters and roofs, you can then click next to continue with the performance task.
With optimised systems 

You can add optimisers in the inverter task by clicking Add optimsers + to the top right of the inverter string. This will automatically add optimisers to all panels on that inverter, if you would like to remove some, this will have to be done manually in the financial task. 

When you then come to allocating the panels the steps are largely similar to non-optimised systems: 

  1. Select the current roof and inverter input from the lists on the left.
  2. Use the Add group + option to sub-divide the input into shading groups and select the group you want to allocate panels to. You should group panels that will get similar levels of shade or that are on different facing roofs. 
  3. Click or drag over panels to allocate them to an inverter input or shading group.
  4. Once all inverter inputs have the correct number of panels, all inputs will be in green and a tick will show at the top. Below all your inverters and roofs, you can then click next to continue with the performance task.

Adding optimisers in the inverter task will not automatically change the generation. 
The generation is a product of the kWp of the inverter, the kk value (which is based on the pitch, orientation and location of the panels) and the shading factor. Putting panels in separate shading groups does not correspond to anything physical but allows Easy PV to factor in differences in the kk value and shading factor on the same string. Without shading groups the generation will not change because the kk value and shading factor will be the same on the whole string, as it would be without optimsers.

Performance and self-consumption

Consumption task

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV, references to MCS only apply to the UK site. The information provided here may not be accurate for easy-pv.com.

The consumption task is alternative to the MCS self-consumption calculation completed in the performance task. Unlike with MCS, the Easy PV self consumption task can be used for projects larger than 6000 kWh and with batteries larger than 15.1 kW.

If you would like to use the Easy PV self-consumption calculations as the basis for your financial projections and in the customer proposal, make sure it is selected in the financial task

Getting started with the Consumption task

You can access the consumption task via the 'Tasks' drop-down menu or from the task list to the left on the project overview page. 

When the consumption task first opens, you'll be shown a popup that lets you configure the settings you want to use for calculating generation and consumption of the system. It will open on the 'Annual consumption' and then you can use the left hand navigation to choose the settings you want to edit. More information on each of the settings is available below.

When you have finished configuring these inputs, click Done. 


Navigating the Consumption task

Once you have configured the Consumption task inputs and submitted them, you can then explore the calculated information.

The left hand side shows the full results of the consumption task calculations and detailed insights. Read the 'View and understand the calculated consumption task data section' of this guide for more information about what's included.

The right hand sidebar on the page includes options to help you navigate through the different sections of insights.

View and understand the calculated consumption task data

Once you have configured the consumption task inputs and submitted them, you can then explore the estimated PV generation, how energy will be consumed by the property, how much energy is imported and exported, the financial benefits and information about battery usage (if a battery is included). This includes annual insights and charts to show changes through the year and over the course of each day. 

The left hand side of the page allows you to navigate to the different sections of the consumption data and also shows detailed insights, and the right hand side of the page shows info the calculations are based on. You can use the toggle on the right side menu to show and hide the inverter and export limitation clipping on the generated graphs.

Generation

This shows the estimated annual generation of the system and whether the generated energy is used directly in the house, used to charge the battery or exported to the grid. It will also show inverter and export limitation clipping if you've turned on this toggle.

Consumption

This shows the total annual energy consumption of the property and where this energy will come from. It shows how much energy is expected to be supplied directly from the solar array, via the battery or imported from the grid.

Import and export

This shows the likely flow of energy to and from the grid over the course of a year. It's likely that there will be more energy exported during summer when the solar array is generating more energy, and more energy will be imported from the grid during winter months.

Financial benefits

This shows the money spent and earned on electricity flowing to and from the grid over the course of a year. It allows you to see the total money earned from export payments versus the money spent on imports, and how would compare to having no solar installed.

Battery utilisation

This helps you understand the modelled utilisation of the battery over the course of the year based on the amount of the the available battery capacity that is actually charged and discharged each day. Utilisation of over 100% is possible at times where a battery is charged and discharged more than once during a day. Low battery utilisation can be due to either insufficient PV generation to charge the battery (often the case in winter, or on cloudy days), or because loads are small overnight and the battery does not fully discharge. If you have low battery utilisation you may want to reduce the size of the batteries or recommend forced charging of the batteries on an overnight tariff to the property owner.


Edit the consumption task inputs

Set the annual consumption 

There are a number of options for setting the annual consumption. 

image.png

Option 1: Annual usage: If you know the annual consumption in kWh (for example from an electricity bill) you can enter it here in the annual usage field.  

When you use this option you can now choose from a variety of domestic and commercial consumption profiles to build an accurate picture of energy usage throughout the year. A consumption profile calculates when energy is consumed—both annually and on a daily basis. For example, in a domestic home, most energy is typically used in the early morning and evenings. In contrast, an office profile reflects higher energy use during typical working hours, from around 09:00 to 17:00. The following commercial profiles are available

Option 2: Meter data: If the property has a smart meter you can upload half-hourly data to get a more accurate projections. The data should ideally span at least a year (but if it contains a minimum of 6 months our algorithm will automatically attempt to fill in gaps where they are detected). The file must have a .csv file extension. If your data is in another format you can export it as csv from Excel, Google Sheets, Libreoffice or any other spreadsheet editor. 

Note that there are many different CSV formats for smart meter data, and we don't support all of them yet. If your upload doesn't work, please send us the spreadsheet at help@easy-pv.co.uk or help@easy-pv.ie and we will see if we can add the format. You can also download our sample spreadsheet here and change your data into this format.

Option 3: Not sure: If you don't know the electricity consumption in the property and it's domestic, you can use a typical values for the size of property provided here. 

Set the import and export tariffs

Here you should select the tariffs this project will use. It is important to set suitable tariffs so the financial calculations for this project are accurate. By default, we'll calculate the financial benefits using your default flat tariffs which you can specify in your financial settings. Alternatively, you can create and select a new tariff by selecting + New import/export tariff.  Click here for a full guide on creating tariffs in Easy PV.

Apply export limitation

In this section you can limit the export rate if this is required by the DNO. Switch the toggle on and then input the annual export limit in kW.

Editing and creating tariffs

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

Setting tariffs is an essential part of ensuring the financial benefits can be calculated as accurately as possible for your customer. These can be created, viewed and edited in the consumption task or the financial task.

You can also set up user level default tariffs in your account financial settings or if you are a member of a Pro team, this will be set by a Pro team admin in Pro account financial settings. 

This guide will detail how you can manage and create tariffs in Easy PV. 

Creating a new tariff 

Name of tariff 

If this is a variable rate tariff, this name will show on the consumption section of the customer proposal. Otherwise, it is just a way for you to manage and navigate your tariffs when selecting them.

Scope of tariff

Project level 

  • These will only be viewable on the specific projects it's created for. 
  • A good option if you frequently change the tariffs on each project. 
oNwWQq5jZD57nWBc-9jswwkzmuujz06d2-image.png

User level

  • These can be used for any projects and set as a default in your financial settings. 
  • A good option if you aren't sure what tariffs your customer is on so want to use standard values.  
iz2Ic6bpeqc93Qnu-image.png

Team level 

  • If you are a member of a Pro Team, you will be able to create Team level tariffs.
  • These will work much like the User level tariffs but will show for all members of your team. 

Once the scope of the tariff has been set, this cannot be edited. 

Price bands

Flat tariff

Variable rate tariff and tariff periods

Editing existing tariffs 

You can view and edit your tariffs in three different places in your account: 

When you select 'View and edit tariffs' you will see the following options: 

Subheading.png

When editing tariffs you can change any of the details except the tariff scope, but note that any changes you make will affect previous projects that use these tariffs. 

Using your tariffs 

Once you have created your tariff either for an individual project or set a user level default, you can then select these in the consumption task and financial task. 

The tariffs set in the consumption task will pull through to the Easy PV and MCS consumption methods in the financial tasks only if they are flat tariffs - if you select a varied tariff then this will only be used in the Easy PV method and your MCS default value will be selected. 

Financial Task

This guide applies to the easy-pv.co.uk and easy-pv.ie versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

Completing the Easy PV Financial task is an important part of designing and selling a PV system. The task has two main areas of focus:

Create an accurate quotation to give to the customer. You can fully cost the materials and services that will be included as part of the installation and set the relevant tax to be applied. It even allows you to apply relevant grants or apply discounts if you want to give the customers money off the installation. Using the Financial task and the Customer Proposal task, you can configure how you want the quote to be presented in the final customer proposal document.

Generate estimated financial projections for the installed system over time. This is important as it will help the customer understand if they are making a good investment by showing likely costs and benefits and how long it might take for the system to break even. You can also include loans, running costs and other custom savings.

Getting started with the financial task

If you haven't already done so, we recommend setting up automatic pricing rules and financial defaults via your account preferences. For Pro teams, these defaults will be configured by the team owner or admins via Pro Account Settings > Financial. This will speed up the time it takes for you to generate an accurate quotation and projections for your project. 

You can access the financial task via the 'Tasks' drop-down menu or from the task list to the left on the project overview page. 

When the financial task first opens, you'll be shown a popup that lets you configure the settings you want to use for the quote and projections. It will open on 'Self-consumption' and then you can use the right hand navigation to choose the settings you want to edit:

Screenshot from 2024-11-18 15-00-49.png

If you have set defaults via your account preferences, these will be automatically applied here. More information on each of the settings is available below.

When you have finished updating the settings, click Save & Exit. This will close the settings popup and allow you to view and modify the quotation, or click to view the projections.  

Navigating the financial task 

The right hand sidebar contains options to switch between the quotation and the projection view:

Quotation view 

In the quotations view, you can view and edit the quotation under the following headings: 

Projections view

At the top of this page you will see the annual generation, payback period, internal rate of return and net present value. A positive net present value is a good indication that the project is financially worthwhile. You will also see the following options: 

More information about configuring the financial settings

The following sections explain all the settings you can configure. Click to expand each section and read more.

Self-consumption 

The proportion of electricity generated from a solar array that is used in a property can significantly affect financial returns. Easy PV has several different methods you can use to calculate self-consumption which you can select from here:

Pricing calculation 

Here you can select which pricing calculation to use, with the option of selecting a default markup on goods or using Easy PV's pricing settings functionality which allows installation prices to be calculated according to rules that you set. 

Guidance on how to set up your own automatic pricing settings can be found in the automatic pricing guide

Financial settings

Here you can adjust the following settings:

Tax settings

In this section, the tax rate for materials and services can be adjusted and you can select whether the customer can reclaim the tax. Business customers can usually reclaim tax paid on an installation, but domestic customers typically can't reclaim tax. Tax rates may be different for domestic and business customers. 

Running costs

Add rows for costs you expect to be incurred in the future. You can choose whether costs are applied on an annual basis (for example a maintenance contract) or as one-off costs (for example an inverter replacement).

Additional savings

Add rows for additional savings, such as from immersion diversion systems or from night charging from batteries. 

Loan

If your customer wishes to pay for the equipment using a loan, you can model this here.

Select the loan amount and term. Then you can choose fixed repayments, where the same amount is paid regularly, or capital plus interest, where in an addition to a fixed repayment an additional amount is added to payments to cover interest accrued. You can set an interest rate on the loan itself, which can compound either monthly or annually. This will usually be higher than inflation.

Grant

If the project is eligible for a grant that will pay for some or all of the cost of the system, you can add it here. 

Discount

If you want to apply a discount to your quote to reduce the cost for your customer, you can do so here. Input a description and choose the type of discount you want to apply. This can be a fixed discount or a percentage of the total cost.

Quotation CSV settings

If you wish to export the quotation as a CSV, here you can customise what will appear including the quotation date, reference, text and the customer address.
