C21e : Solar electric roof tile

C21e is a unique, roof integrated, solar electric tile using the most efficient solar cells in the world.

This particular solar application works best for new builds or when a homeowner is re-roofing, because each photovoltaic tile replaces four conventional roof tiles and is attached straight to the roof battens.
C21e has many benefits over conventional bolt-on solar panel systems and has won a host of industry awards.

C21e - Key Features

• No extra planning - no need to alter roof lines, colour or pitch. C21e tiles sit flush with conventional roof tiles.
• Standard installation - tiles fit with conventional roofing practice without the need to adjust battens. One solar tile takes the place of four standard tiles.
• No specialist skills - all roofing work is carried out by the roofing contractor allowing electrical and plumbing work to follow build programme.
• Fast to fit - tiles are integrated in exactly the same way as conventional interlocking tiles.
• High power output - 52Wp per tile, less than 8 square metres per kWp (kilowatt peak).
• Discreet 'SunPower' PV laminate - blends superbly with regular roof tiles offering an unrivalled
  aesthetic.
• Back mounted contact strips - increase effective collector area and reduce surface glare, typical with standard solar cell technology.
• Integrated 'thru-flow' ventilation - enhances PV performance.
• Power output - guaranteed for 20 years from date of commissioning.
• No electrical work required on roof - avoiding delays to the build programme.

• Tiles arrive on site as complete units - avoiding the need for on-roof assembly.
