ENERGY MEETS DESIGN – WF24 Integrated Panels

The WF24 panels are a sturdy, wooden framed panel designed for mounting vertically on sloped roofs with either tile or slate finish. All sealing brackets are easily assembled and clip into position to allow for a fast and professional installation, the black finish on these panels make them integrate easily with the standard black roof used in the British Isles.

With the WF24 you will find a solar panel that has been designed for integrating seamlessly with Irish slate roofs. any installer that is familiar with the "Universal" flashing kit will know how un-universal it is when it comes to a tegral slate roof. Evergreen Energy have designed a flashing kit that is specific to Irish needs and will be as simple as integrating a Velux window.
