Read my post. 10kW was priced at €11,500 in December. Currently cheaper.

Hello @nordanney,

Am I correct in assuming you mean net prices? Would you be willing to share your provider?

Last year in January, I paid a total of €12,000 gross for a 9.2 kWp system.

70% soft and good is. The normal base load, at least for me with 350-400 Wh, never covers the peak. But there are enough appliances that can be run alternately around midday. Washing machine, cooking, electric car, dishwasher, hot water, etc.

And that only since mid-April. That goes on until mid-September. With the heat pump in heating mode, you don’t have to worry about that anymore.

A battery compensates for peaks and drops during cloud cover (yesterday it “saved” me 3.3 kWh) and can store energy that would otherwise not be compensated.

With 16% VAT? That would be about €10,300 net.

Are there actually regional differences in the price per kWp? All five quotes I received were above €1,500/kWp in the Berlin surrounding area.

Just the usual 19%, that was before Covid.

You already answered your own question, I also had offers ranging from €12,000 to €17,000.

In addition to balancing out peaks and dips during cloudy periods (yesterday I “saved” 3.3 kWh), a battery can store energy that would otherwise go unused.

Does this mean that having a storage system makes the 70% figure highly recommended?

@halmi, thanks!
I also received an offer of 1100 EUR (net) for an 11 kWp system, but without scaffolding.
