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?

Is the zero VAT rate applied to the entire package including the battery storage, or how is this regulated?
Photovoltaic zero VAT means gross equals net.
How can I get a VAT refund just for the battery storage if I no longer charge or receive VAT and do not file any tax returns?

How long is the cover supposed to last?The gas price cap is planned until April 2024, and electricity prices are expected to follow a similar timeline. However, I couldn’t find any official information quickly. I think we need to prepare for prices around 40–45 cents (USD) in the medium term. I don’t believe the myth of cheap renewable electricity. While generating electricity might eventually become cheaper, the expensive part is storing it or maintaining fossil fuel capacities for times when wind and solar power production is low.

How can I get a tax refund for the storage alone if I no longer pay/receive VAT and don’t file a tax return anymore? If you only buy storage separately—not as part of a package—then as far as I know (as before) there is no refund. So you pay the full gross price. That’s why retrofitting is always the worst option. Prices today would have to drop by 19% before you wouldn’t lose money on a retrofit in a year.

I think in the medium term we have to expect prices around 40-45 cents (40-45¢), and I don’t believe the myth of cheap green electricity. The electricity itself might eventually be generated at lower costs, but storage and maintaining fossil fuel backup capacity for periods without much wind or sun is expensive. For electricity? Yes.
For gas? We are heading toward an oversupply.

xMisterDx23 Nov 2022 12:55I would be interested to see the calculation that makes the battery storage a good investment in summer, especially with 7 kWh capacity costing almost 7,000 EUR.
It fills up quickly during summer. Then what? Does one really consume an average of 7 kWh at night during summer? Because if I fully charge the battery at the beginning of June and then only use 1-2 kWh per night, it doesn’t make sense.
Around two-thirds of the photovoltaic energy is generated during the six warm months. During the three mild and especially the three cold months of the year, the photovoltaic system at best only covers the daily demand and usually not even that in the cold months.
Alternatively, one could install an air conditioning unit to use the electricity during summer. But then the battery storage would no longer be necessary.
You can also take a look at the load profile of a house heated by a heat pump. The highest electricity demand occurs exactly when photovoltaic production is almost zero.
