Lower Saxony subsidizes photovoltaic storage

5.1 The grant is awarded as a non-repayable subsidy in the form of co-financing for project funding.

The process is also not completely clear to me. We should probably inquire about it at NBank. Maybe they will publish more information about it soon. So far, I have not found anything about it on their homepage.

I don't think I will exceed 10KWP anyway... So this funding will not be an option for me...

About 5 KWP would be enough for me and a storage system. And then a wallbox.

Combining the whole thing with [Bafa]. That would be great!

We currently have 4.55 kWp and would, if the funding comes through, like to possibly increase to 8 kWp and add storage. I wonder how I can do this most efficiently. I would like to change the solar installer, can I get the suitable modules from any other provider? The inverter would presumably need to be replaced or a second one added, no idea which makes more sense.

I always wonder why people don’t fully utilize the roof, as long as it makes sense in terms of yield?! Especially now that there is still a guaranteed feed-in tariff for 20 years! Everything beyond my own consumption is compensated. My 8.05kWp system produced 6800kWh in 2019, of which I consumed almost 1800kWh myself. This corresponds to a saving of electricity costs of about €330. The remaining 5000 kWh I fed in at €0.12 per kWh. That makes a compensation of about €600! Well, you still have to deduct taxes and other costs, but there is still a lot of money left over. I believe we are currently at 8.64 cents/kWh feed-in. But the larger the system, the faster it amortizes.

You would need to go up to at least 8.55 kWP, otherwise there is no subsidy.

The system can certainly be expanded by any other solar installer. Why shouldn't that work? Find a good solar installer and check with them what your current inverter could handle. Buying a new inverter just for 4 additional kW doesn't sound economical to me.

: Why shouldn't 10 kWP fit on your roof? The roof doesn't look that small.

But the bigger the system, the faster it pays off.

Fully agree!

Have you also occupied your north side etc.?
Or how is the system divided on your end?
