ᐅ Photovoltaic System: Costs and Savings Potential – Experiences?

Just to make sure I really understand correctly, does that mean you will receive the EVG as of January?

Yes.

We are also still waiting for the first feed-in tariff payment, which, according to a phone inquiry, could take another 1-3 months.

Sometimes you really overthink things... the solar installer fills out a form, and as the system owner, you just enter a date in the system, and that's it. Just talk to each other.

As I understand it, the date of commissioning applies. That means the modules are connected and the inverter is operational. According to the solar installer, this can, if necessary, also be done briefly using temporary construction power. A photo as proof of the running inverter would be sufficient.

Hello everyone!

I have now received a quote for the photovoltaic system and battery storage. What do you think about the system, manufacturers, and the price? At first glance, the offer seems affordable, and the system and manufacturers appear to be high quality.

The sizing is currently just an example for applying for funding and can still be adjusted individually. What would be sensible? As much photovoltaic capacity as possible in kWp, with a battery storage capacity in kWh of half that, or something else?

In my opinion, the cost for the mounting frame (1,426.50 EUR net) should be removed, as scaffolding is already available anyway. How does it work with the ladder scaffold for roof installation?

That seems to be a bit more than 10 kWp (kilowatt peak), right?
At first glance, the offer looks well-calculated in terms of price/performance.
I've never heard of the module manufacturer before.
BYD is known. They are supposed to be quite reliable.
What I’ve learned: fill the roof as much as possible (sensibly). Keep the storage battery as small as possible.
Whether SolarEdge is really necessary, in my opinion, depends on the roof conditions and orientations.

The mounting frame refers to the aluminum rails on which the modules are bolted. You can’t proceed without them.
However, the ladder scaffolding should be unnecessary since you already have scaffolding.

The modules are assembled in Austria, but the materials come from China – so Chinese modules with a European label. I have no personal experience with these, and they are probably quite rare here.
BYD is almost the standard. You received an offer for the more affordable option.

In my opinion, the price-performance ratio is absolutely reasonable. Is SolarEdge necessary?
