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?

Keep in mind the battery’s lifespan… every kWh that goes in and out of the battery will cost you money as well! In this case, with such a big difference, it might still be worthwhile, but you should calculate that individually…That’s clear. I have had daily differences of 60–70 cents before. With LiFePO4 batteries, the cycle life situation is looking quite good nowadays.

The answer likely lies somewhere in the combination of these two factors. Calculating this right now would be quite difficult for me. With the commonly used 5,000 to 10,000 cycles today, I would generally lean towards charging from the grid.

I didn’t know that was possible. So, there’s a button or do you use an app to tell it to draw power from the grid now? I have no idea if something like this is available out of the box. I’m programming it myself (the logic based on solar forecast, price prediction, consumption curve, etc.). Of course, an electrician has to enable this functionality. From what I’ve read online, others have done this too. You just have to make sure that stored electricity is not fed back into the grid... That’s "forbidden" 😎 Well, who would be crazy enough to buy at more than 20 cents and then sell at 8 cents... Please...

Well, I hope for you that if either one breaks down (battery or inverter), you don’t necessarily have to replace the entire unit or that the manufacturer is still available. :p
You keep throwing in bits of information here. That doesn’t help someone interested in battery storage at all.
So, tell us: When did you buy it? How large is the battery? How much did it cost you? And how many cycles do you get per year? Or, how much do you charge in and take out? I hope so too. :p
In principle, I do have a 20-year warranty on the device, but there is for example a deductible if a defect occurs within those 20 years.
In the end, it’s all speculation and hoping that things turn out as calculated.
Whether the battery really pays off, I will only know after 10 years.
Just briefly to answer your question about the key data.
Battery cost: €6,000
Size: 10 kWh
Purchase date: May 2020
Energy charged INTO battery in 2021: 2653.4 kWh
Energy discharged FROM battery in 2021: 2607.0 kWh
