## Datasheet Solar Electricity For Plain Tiled Roofs

Solarcentury's C21e solar plain tile system delivers universal compatibility with small format plain tiles and an excellent performance per m2, providing a perfect complement to a traditional plain tiled roof.

No extra planning: The C21e solar plain tile system sits 
flush with standard roof tiles, to provide a traditional 
finish. They protect your home from the elements whilst 
producing electricity.

Ease of installation: Fitted to standard wooden battens 
using traditional roofing practice, with one C21e 
covering the width of approximately seven conventional 
tiles.

No specialist skills: Designed to be installed by roofers, 
as part of the roof build, the C21e solar plain tile 
system fits 'straight out of the box' without the need for 
bespoke flashings or fillers.

Fast to fit: As fast to fit as traditional plain tiles, and 
complete with simple click-to-fit connectors, allowing 
all of the electrical work to be carried out within the 
building.

Screws and fixings supplied:
C21e stainless steel roof hooks with Torx fixing screws (T20) three per C21e unit, C21e stainless steel starter course hooks with Torx fixing screws (T20) three per unit on the bottom course, adjustable channels and tile interfaces.

Refer to fixing specification for the plain tiles to be installed alongside C21e. * If the minimum pitch for the conventional plain tile is greater than the minimum pitch for C21e, the fixing specification for the conventional plain tile should take precedence. Please refer to the C21e plain tile installation guide for details.
