Topic - Solar PV and heat pump

Philip on 06 Jul 2014
Anyone chosen solar PV to complement a heat pump? If so, what size PV did you go for. We're looking into the maximum grid connection we can have without paying for upgraded cable, but assuming we could go to 8 (which is about the limit of capital I want to invest) how did you match PV size to heat pump. I've got 90m2 of roof on each of due E and due W, so I'll only get 75% of S performance.

I was thinking that trying to match the spring / autumn output not to exceed the running of the HP would mean being able to use generated energy in the day to match the heat pump. Anyone got a better idea?
