Choosing a 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 first create a project you will get the choice of the which design mode you would like to use. In Easy PV there are four options, each with particular applications.

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:

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.

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.

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:

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.

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.

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.

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.

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.

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.

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

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.

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.

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