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?

Do you have more information regarding the legality or practical issues here?There are hundreds of websites about DIY battery packs. It is completely legal – but the forklift batteries or 32700 cells or whatever that are usually used have also become quite expensive by now. You just need a certified inverter for the battery.W

The question is whether a storage system costing 7,000 EUR is worthwhile, especially if you are financing it at over 4%.

The question here is whether a battery storage system costing 7,000 EUR (about $7,700) is worthwhile, especially if it is financed at over 4%. Probably not. On the other hand, it’s hard to predict future conditions. Two years ago, calculations were done and it was said, “the kilowatt-hour from the storage system costs 40 cents, so it’s never worth it.” Today, people are glad to find offers below 50 cents...

Today, people are happy to find offers below 50 cents... Starting January 1st, 40 cents will apply for 80% of the annual consumption. And how it will look in two years, nobody can reliably predict.
It’s also true that the prices for photovoltaic systems and batteries have increased significantly. This system could have been bought two years ago for two-thirds of the price, if not half... and at 1.5% interest, not 4%...
