Listed building goes solar with Solarcentury’s solar electric slates

Designed by Solarcentury in the UK and launched in March 2011, the C21e slate can be integrated across a wide variety of natural and fibre cement slates, and is gaining popularity with installers looking to widen and differentiate their domestic solar offer. The product, and its counterpart the C21e solar electric roof tile, helped Solarcentury secure a Queens Award for innovation earlier this year.

Elliot Parkhouse, Managing Director, TheGreener Group said: “We’re proud to be Solarcentury Network members, and in particular looking forward to helping more period properties make savings with Solarcentury’s new C21e solar slate. Our solar slate installation was the result of traditional solar modules being rejected at planning stage. Samples of the C21e slate, along with a full listed building application, were given to the local planning office and the consent was passed in the Summer.  With so many listed buildings in the Chester area, we’re keen to let the owners of these fantastic properties that they needn’t be left out when it comes to solar.”

Martin White, Head of Products and Services at Solarcentury said: “Over four million homes in the UK have slate roofs, until now their options for going solar were limited to bolt-on modules  or semi-integrated systems requiring specialist installation. With our new universal C21e slate, designed to fit straight out of the box, any slate roof can now benefit from going solar, without compromising the country’s roofscape”

The Greener Group installed 3kWp, 66 C21e slates, producing 2500 kWh annually and just over £1,000 per year in Feed in tariff payments, index linked for 25 years.
