ᐅ Costs of Photovoltaic Systems with Energy Storage

Hello everyone,

I would like to hear your opinion on a quote I received.

- Photovoltaic system with 10 kWp
- Storage battery with 6.5 kW
- Including installation

About 25,000 euros

That seems a bit high to me... so I’m asking here in the forum.
Thanks and best regards

We have a current offer for 18k, but only 5 kWp.

One kWp costs about 1,400 € gross. For the battery, kW costs about 1,000 €, decreasing. You can calculate yourselves if you are paying too much.

But not with scaffolding, connections....

We have the following offer:

Battery storage HVS 5.1 (5.12 kWh) and 18 photovoltaic modules of 340 watts, heat pump for a total of €16,654.19 including installation and VAT.

Problem: Battery storage is currently not available because the chip is missing, which is reportedly in short supply everywhere – including at Mercedes and VW.

In Lower Saxony, there is a subsidy for battery storage from the NBank.

What kind of intelligent connectivity does the system offer? (smart home, e-mobility, power to heat, etc.)
What charging/discharging capacity? (few provide this information)
Any special requirements for modules or installation conditions?
