This West Midlands property was being extensively renovated, including a completely new roof. The owner wanted a roof-integrated Solar PV panel system to compliment the aesthetics of the property. Careful planning to maximise the size of the system was required due to the positioning of dormer windows, shading and limited roof space.
Following a survey of the property we designed a split system utilising two roofs and using 12 SunPower 327 watt panels with SolarEdge optimisers to limit the effect of shading. The panels were installed using a GSE roof-integrated system, a tray-based design which allows the panels to sit flush with the tiles, instead of the traditional on-roof installation.
