Photovoltaic system / heat pump, do you have 2 meters?

Yes, although he already did some "advertising" for storage. He meant that the durability (depending on the number of charge cycles?!) has improved significantly. But I will probably refrain from it.

So he is a she And no, no advertising, but that's how I would do it. If storage, then now because there is still funding

So he is a she

Oh, I see

2 meters in cascade, since photovoltaics will cover only about 1/4-1/3 of the heat pump electricity (~3000 kWh avg.) (even an advanced hourly forecast tool, not a rough monthly estimate from sellers without heat pump modeling). A 10 ct difference in the tariff (20 vs. 30 ct/kWh) makes a difference of 200-225 € per year. The meter fee is 60 €/a. A neighbor with exactly the same house structure and heat pump is trying it with a combined meter and cloud. Then we have an interesting almost direct comparison (SSW vs. O/W system, differently dimensioned, different battery).

If the difference is that large, a cascade can already make sense. For us, it's just 3.9 cents with €113 more base fee.

Is this limitation due to the locally available providers?
