Case Study: The Merrill FamilyWalking into the Merrill’s familyhome in Somerset, it all seemsvery normal.The only evidence that the Merrill’shome is powered by C21e solar tilesis the small display unit on the kitchentable showing how much energy isbeing generated.“It’s hard to remember the solar tilesare there sometimes” says Dad, DavidMerrill. “But it’s a great feeling to knowthat we’re generating our own power.”“The financial gains area fantastic bonus.”David MerrillWhen David had the home re-valued after the solar installation he waspleased to find it had increased in value by 6% because of the tiles alone.

Case Study: Mr & Mrs HughesBob and Helen Hughes bought their18th century Georgian house in 2007and spent a year on renovations.Being keen to minimise both energy usageand bills, they installed loft, underfloor andwall insulation as well as double glazing..To reduce the need for increasingly expensiveelectricity from the grid, the Hughes chose tore-roof their home with 36 C21e solar electricroof tiles. Ordered via their local buildersmerchant, the Hughes’ builder installed thetiles after a morning’s training from Solarcentury.Producing 1,500 kWh per year, the systemprovides a large element of the home’s electrical needs, saving 850kg of C0 2emissions from entering the atmosphere each year.Bob comments: “Whywouldn’t you install solarelectric roof tiles? It’s anenvironmentally sound andeconomically efficient thingto do. As we were spendingon renovation anyway, werealised the cost of the solarwas comparable to otherhome improvements.””He adds: “We’re reallyhappy to have installed thetiles and feel they add to theappearance of the house.We really want to inspireothers to do the same.”

At night, power isimported from the grid in the normal way.2.1.3.Does it really work in the UK?Yes. The cells in the tiles & slates only require daylight to work, and willeven generate energy on cloudy days.A 54 tile or slate C21e system can generate all of the electricity for anenergy efficient home 1 and well over half for a typical UK home 2 .Does the system need batteries?No, the system is connected to the national grid.
