Hello everyone,
I have tried to learn about photovoltaic systems, but so far I have mostly come across very optimistic (Google) advertising offers. Here in the forum, I have mainly read critical (mostly older) posts.
About my concern:
We are currently planning a (pitched roof) new build for early 2017 with a south/east and north/west orientation, and so far we have followed the classic gas condensing boiler/solar thermal system with a hot water storage tank concept. A colleague at work brought photovoltaics to my attention. When he told me that he (theoretically) generates 3500 kWh/year with a system he bought for 7000€ about three years ago (but without a battery storage), I became curious.
I would like to know how realistic it is to achieve such output with an investment of around 10,000€ and to use it entirely on your own? We currently live in an apartment (3 people) and consume about 3800 kWh/year. Of course, I have quickly dismissed the idea of an easy profit from the “fast market”...
If even remotely possible, I would appreciate any literature or pricing information for such a project.

... that’s not quite right either, but that’s no longer the topic now. You can quickly look it up yourself.True, we’ve drifted off-topic. Just calculate it yourself or consider what an investment in a photovoltaic system with a battery storage, including taxes, would cost. You’ll easily exceed the €17,500 (about $18,500) revenue threshold, meaning the small business regulation won’t apply in the first year of establishment at the latest, it will become invalid the following year.
By the way, I don’t need to research this anymore since I’m married to a small business owner who’s constantly dealing with revenue limits, has exceeded them at times and thus lost the small business status, but later opted back in—with support from a tax advisor. We didn’t fall into the trap mentioned in #23 because we were properly informed.
So, I feel quite well prepared in this regard, especially since I have also worked as a full-time self-employed person myself.

+ anyone who exceeds the €17,500 (about $18,500) limit should consider whether it makes sense to register a photovoltaic system in their own name.Yes, registering it under your partner’s name can be a good solution.

I could follow that reasoning if you were an expert in the field. But that’s not the case.Correct, I’m not an expert. However, I don’t see why a clear argument should lose its validity because of that. It’s a pity that you apparently see it differently and don’t want to argue your point. But of course, I accept that—I can’t force you 🙂 We’re among engaged amateurs here, sharing our insights. Expert advice is naturally more valuable. Just be careful not to confuse a salesperson with an expert.

Based on your “simple facts,” you come to this conclusion.Return on investment calculations for photovoltaic systems seem quite complex to me because several tax issues are involved. Therefore, a simplification is necessary. If the simplified calculations already indicate very clear trends (which I believe is the case here), there’s no need to argue over the last decimal place.

Admittedly, I’m taking it a bit easy now by not presenting another economic analysis or addressing your “simple facts” in more detail, but it’s not worth the effort for me.As I wrote above—shame. I am willing to learn.
Maybe another time.
I recommend searching on Google for “photovoltaic” and “forum” and simply reading what’s there. You’ll even find some unusual cases applying the small business regulation (motivation, as I see it: no desire for taxes/accounting, ROI doesn’t matter).

I assume that laien.haft is not referring to tax issues, but rather to technical boundary conditions, meaning the integration of electric vehicles and/or participation in smart grids or smart markets.
I agree that Alex85’s calculations may be correct on their own, but the system boundaries are incorrectly defined, so certain effects cannot occur.
It’s a pity that this was not explained in more detail.
