Photovoltaic system air-water heat pump - profitability single-family house KFW55EE

Per module, sqm or "football field," right? :)

In my opinion, always per kWp. (Too few words)

Currently, our photovoltaic system delivers 540 watts under completely overcast skies (at approximately 13 kWp). The house currently requires just under 800 watts with an air-to-water heat pump. ;)

Then it is even more overcast here than with you: right now, only 100W (9.1 kWp) are coming from the roof.

Over time, you get quite good at estimating the current yield just by looking out the window. ;)

correct. At the moment, it is also fluctuating a lot. Well, we are waiting for the sunshine tomorrow or the day after tomorrow. :)

I am also stuck with the planning right now, but without assistance it takes time.. Currently, for example, I don't know which stands I need :-) but that will work out.





Then I have access to the system from my buddy, today's yield 10.2 kWh for a 9.9 kWp system.



And when you're done, you no longer need all the things you have acquired.

That goes faster than I thought!
