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.
