Solar Panels and Heat Pump
Solar panels powering a heat pump for space heating.
17 panels in total, 7 for the heat pump.
The heat pump produces an input water temperature of 45 degrees Celcius, which suffices for most of the heating season.
Result: electricity neutral and more than 1000 m3 natural gas saved annually.
Dutch government 5 kW heat pump national subsidy: 1000 euro.
