Our calculator works out quickly and easily your project, so that you spend more time fitting and less time designing. Sketch a roof and then choose from a list of solar panels or add your own panels. Once you’ve done this, you can download the construction plan and the list of materials needed.
Manage your projects
Our calculator makes it possible to easily manage all your projects in one place. Select the location in the calculator and then start designing. You can also add special conditions that need to be factored in when fitting the system, such as wind, shade or adjacent buildings.
