Starting with 1.6 kW of solar electric (PV) panels in 2000, this household has caught the bug and continues to add renewable energy. Now up to 1.9 kW of PV, they have also added four solar thermal evacuated tube arrays that provide hot water for radiator and in-floor heating. A recent addition also adds passive solar heat gain to the south side of the house.
