These Kent homeowners wanted to reduce their electricity bill and earn a return on investment from the government Feed-in Tariff. The property was suitable for Solar PV as a flat roof area could be used as well as the south facing roof elevation.
EnergyMyWay installed 8 Sunpower 327W panels; 4 on the rear south facing roof and 4 on the flat roof area, using ballasted Hilti low profile A frames . To make the most of the solar energy produced, an Immersun2 divert device was connected to the storage heater so excess solar energy can be diverted into water heating.
