# Custom solar panels

<p class="callout info">This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [easy-pv.ie](https://easy-pv.ie) versions of Easy PV. The information provided here may not be accurate for easy-pv.com.</p>

To add a custom panel in Easy PV navigate to **My Components** &gt; **Solar Panels** on the left-side menu or **Components** &gt; **Edit Solar Panels** from the top drop down menu.

You will need the **datasheet** from the manufacturer so Easy PV can appropriately perform calculations for inverter sizing and system output. Below you will find guidance on how the information in the datasheet corresponds to the values Easy PV asks for.

#### **Creating manufacturer** 

When adding any custom panel in Easy PV you first need to add a custom manufacturer category which allows you to organise your custom components. The components added will be categorised by their manufacturer when it comes to select them in a project.

After inputting the name for the manufacturer, re-open your custom manufacturer and you will see the additional option to add a solar panel.

#### **Inputting information from datasheet** 

You will then need to input the technical information found in the datasheet for the panel. If your data sheet has two sets of data you should use the values for **standard test conditions (STC)** not the values for Normal Module Operating Temperature (NMOT). This is a list of potential variations for each value required to add a custom panel:

</div></div>The panel will auto-save once all the required fields are completed. Once you have added a panel successfully, you’ll be able to select it in the list of panels when creating a new project in the panels task, listed under your custom manufacturer name.

#### **Additional details and rules** 

- The **photo** and **description** for the panels will show up on your final customer proposal, to edit the image of the custom manufacturer or component, click on the default image and upload from your files.
- There is a set of rules which you can select or deselect as you need, these are the default settings for new panels: [![image.png](https://help.easy-pv.co.uk/uploads/images/gallery/2024-10/scaled-1680-/PBOLVPgei9DDS1Qg-image.png)](https://help.easy-pv.co.uk/uploads/images/gallery/2024-10/PBOLVPgei9DDS1Qg-image.png)
