Hello everyone,

Since I have no prior experience, I would like to get some general information.
Our new building will be heated using an air-to-water heat pump.
What would generally and overall be the advantages, potential savings, and costs of installing a photovoltaic system on the roof? Is it worthwhile or not?

If you just throw a formula out there, you should explain it somehow. I have no clue what you mean!

And what does it matter whether the purchase is made with equity or financed with debt when deciding about VAT registration (KUR) or not? It’s only about the VAT that can be reclaimed and the VAT you have to pay on personal use. How the system is financed doesn’t matter at all.

Of course, the effect is greater the higher the system costs are. But I still maintain that even for smaller systems it’s worth it if you take into account the hours spent for the effort.

Regards,
Specki

Yes, you first have to reach such an hourly wage with other tasks.

Here is the full quote from @seth0487’s article
And shortly afterwards, he also expressed what many in the German solar industry have been waiting for a long time. “We will lift the subsidy cap for photovoltaics,” Altmaier declared. Although this has actually been political consensus since the presentation of the climate package in autumn 2019, the Minister of Economic Affairs had so far found it very difficult to say this publicly, as Altmaier, in his role as Federal Minister for the Environment at the time, had “invented” the 52-gigawatt cap due to the then-high costs of photovoltaics and had included it in the Renewable Energy Act. However, Altmaier did not specify on the conference when exactly the photovoltaics cap will be removed. He only said that he is confident that the 65-percent renewable energy target by 2030 will be achieved, and that, in addition to photovoltaics, more offshore wind farms should be built.

But yes, the effect naturally increases the higher the system costs are. Still, I maintain that even for smaller systems it’s worthwhile when you calculate the hours you spend on the effort.

I already mentioned where to find the most detailed explanation. It’s the first result on Google.

I didn’t mention anything about financing or equity?

Furthermore, I said that in my specific case it would bring about 400€ (euros), but it probably doesn’t matter to me. For example, if I buy an electric car tomorrow and charge it at home, my personal consumption will increase significantly and I might even end up paying VAT on that. Personal tax rate also plays a role—mine is shown above in the calculation. My break-even point is about 4,500 kWh (4,500 kilowatt-hours) of personal consumption.

What I also find funny about the whole tax authority topic:

Our neighbors installed a photovoltaic system about 3 years ago. I once asked them how they handled the tax authority. They looked as clueless as two deer in headlights and had no idea that they needed to report anything to the tax authorities. Surely not an isolated case(?).

A friend bought a house with a photovoltaic system. He knew he was supposed to report it to the tax authorities somehow, but since neither the previous owners, the real estate agent, nor anyone else had any clue how or what to do, he just left it as it was...

Sorry, I misread.

@Lumpi_LE
Ignorance is no excuse.
It might work out. But if the tax authorities find out, there will be serious trouble. Since the energy supplier, who pays the feed-in tariff, also reports this to the tax authorities, it’s quite possible that the tax office will eventually notice that the corresponding entry doesn’t appear anywhere on your side.

I don’t know how quickly they connect such information or how likely it is they will find out. But I wouldn’t take the risk.

From today’s Photovoltaics Magazine:

At the “Handelsblatt Energy Summit 2020,” the Federal Minister for Economic Affairs, P. Altmaier, announced that the gigawatt cap will be abolished.

@halmi Why don’t you put the photovoltaic system into operation? You don’t need a grid connection or meter for that and you secure the currently valid subsidy rate. Possibly connect to temporary construction power.
