@louis also,, get quotes and system buildouts from at least two solar installers. I’m really interested to hear how the details work out in Germany! Green Mountain Power here in Vermont is very pro solar and our state has fantastic tarriff structures. Prior to heat pumps, we basically laid nothing for electricity to the grid. After heat pumps, we’re paying some, but less than our oil costs. That’s with us running a 400 gallon hot tub and keeping thermostats at “in-law visit” levels 😅
