ᐅ Photovoltaics at Any Cost – Current Situation and Available Options

Hello everyone,
After countless rejections due to overload, availability, and delivery issues, I have finally received an offer for a photovoltaic system.
The system is planned for our new build (completion in 2023). We have a gable roof, almost south-facing, with a 30-degree pitch, fully usable, about 50 sqm (540 sq ft) of roof area per side.
The house is being built in Bavaria, about 60 km (37 miles) from Thuringia.
The offer surprised me a bit. The following items are included:
14x MAXEON modules at 430 W each, heat pump system, totaling 6.02 kWp - €11,138
1x Tesla Powerwall 2.0, 13.5 kWh - €10,400
Installation, etc. - €3,130
Total: €24,668 net
I find that quite expensive. I would leave out the battery anyway, but even then, I think the price for the 6 kWp system is too high. Apparently, this is currently the price you pay in Bavaria if you can find someone at all. For me, the question is whether it even makes sense to invest right now or just pay for electricity. Of course, it’s a matter of calculation, but if you follow the discussions here, those prices seem sky-high — or not?
Is it better to get offers from other regions? Are there any recommendations around the 97XXX area?

Can you tell me where I can find the necessary information about what I need to take care of and by when?Each building authority (building permit / planning permission office) offers the relevant forms and guidance online. Check out my post #51.D
DaGoodness19 Aug 2022 11:07For me, the value-added tax was monthly in the first year (2020), quarterly in the second year (2021), and this year it is annual. Once you know how it works, it’s actually quite simple. For self-consumption, you just apply a rate of 20 cents per kWh for taxation, and for the feed-in, you have your monthly advance payment from the energy provider. So, in principle, there are only two values each time.
In previous years, we had our income tax returns prepared by the income tax support association (cost: 195€ per year). Unfortunately, we are no longer allowed to do that now. I inquired at several tax offices and was always quoted costs between 450€ and 500€. Therefore, I only submitted the VAT return for the photovoltaic system and have not yet filed the income tax returns for the last two years. There was talk at some point about changing the regulations so that the income tax support association could also handle tax returns for private use of photovoltaic systems. I’m not sure what came of that.
Otherwise, I will have to do the income tax return myself at some point. Even if I don’t claim everything I theoretically could due to lack of knowledge, I don’t believe a tax office would get me 500€ more back.

Now I’m chiming in again on this topic. After countless discussions and phone calls, I finally have an offer that is still reasonable at the moment.
- 10.08 kWp with 24x IBC MonoSol 420 MS10-HC-N modules including installation (without scaffolding) for €19,000 net → €1,884.92 per kWp
- Same system with 7.68 kWh battery storage for €26,800 net
We will probably install the system without storage, or we are still waiting for another offer. Whether the storage is worthwhile with a heat pump remains a question I can’t quite get to the bottom of. Some say definitely yes, others say the storage is too expensive, and the calculations always vary depending on different parameters.

Whether a storage tank with a heat pump is worthwhile is still a question I can’t fully address. Definitely not for the winter period.
BUT: think about the summer and transitional seasons, and your domestic hot water – this is where my storage tank does its job.
And about 1000€ per 1 kWh is acceptable at the moment. Have prices ever been better?
If you install the storage system now, you can also claim the tax credit for it. I believe doing this later is difficult or even impossible. I am in favor of storage, but no one can provide you with an exact financial or ecological calculation. There are too many dynamic factors involved to determine if it will pay off in either respect. In my opinion, you should trust your gut feeling here. And if you are planning for the medium or long term, just ask yourself whether you expect the cost of storage systems to decrease during that period (crystal ball).
ateliersiegel23 Nov 2022 08:28So far, we had not planned for energy storage because advisors said it was not worthwhile.
Meanwhile, there is war nearby, and "Fridays For Future" rightfully challenge our comfort.
The current plan is to set up the system so that, in the event of a public power grid outage, we can continue to have electricity from the photovoltaic system as far as technically possible. This requires a battery and a different inverter (I am not knowledgeable and rely on our electrician).
We had already purchased the electric car after installing the photovoltaic system on the first roof area to store self-generated electricity, but the Tesla quickly charges on sunny days (and unfortunately does not provide its electricity back). Now a second roof area is being added.
This costs a lot of money, and I do NOT believe it is urgently necessary, but since we can still afford it, we have decided to proceed this way.
