Collaboration of air-water heat pump, photovoltaic system and storage

Nominally 9.99 kWp - 9W nominal power per photovoltaic tile, 1110 pcs. in total. How much goes into the storage not only depends on the yield but also on the consumption curve. Our house has a low base load and a number of consumers that draw quite a bit of electricity when operating. As long as these are not used, quite a bit goes into the storage.

This is quite surprising that you manage to fill the storage with 9.99 kWp in this weather. Is your system East/West? That could be helpful in this weather, yet it would still be a lot to fill the storage that way. You also have other consumers in the house.

I have 7.5 kWp and 8kW storage, and it is full shortly after 1 pm and lasts from sunset until just after 6 am for the household and heat pump.

How large is your photovoltaic system? I live in the West, and even on sunny December days, more than 3 kWh did not come from the roof. But if you come around with a system capacity of 20 kWp, then that fits again

I recorded a yield of 28.9 kWh on 30.12. System size 7.5 kWp south-facing roof.

With 10kWp in December, I could have fully charged a storage 9 times. Best day for me only about 18kWh.

I will not install a storage for the foreseeable future.

Exported 115 kWh in December. In the purely theoretical ideal case without losses, etc., this would mean a maximum saving of €20 on electricity consumption in December through storage. November was almost identical.

Your yields sound very good! I will find out how it is going with the neighbors ... I assume my system will then be mostly in the shade due to the low sun (flat roof with parapet). Otherwise, this strong difference is hardly explainable. Yield in December was a measly 70 kWh
