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?

That would mean in summer you’re using nearly 1kW of power from 10 p.m. to 6 a.m. Wallbox? Nonsense, the sun sets much earlier and rises later here. Wallboxes are used at night too, but it’s obvious the battery won’t last for that 😉 So rather 13-14 hours without sun.
But if you tell me where I can get sunlight at 9:59 p.m. I’d really appreciate it :p
In December, I also have the outdoor sauna running with a 9kW stove ;-) The battery is clearly too small for that as well 🙄

In December, I’ll also have an outdoor sauna with a 9kW heater ;-) The battery capacity will be far too small for that anyway 🙄How much sun do you get on average per day in December, and how full can you get your storage system during that month?
I haven’t been paying close attention... do you have a heat pump? Because then there’s almost nothing left over. In December, almost 100% is used directly.

I didn’t pay close attention... do you have a heat pump? Because then there’s hardly anything left. In December, almost 100% is used directly. That is often the case with a small system. I have a ground-source heat pump.
Today it was just under 16 kWh, but it was relatively sunny.
In addition, I also charge my car with self-generated electricity whenever possible.
So in winter, I have nothing left over. Yesterday it was only 11 kWh, and the day before even just 1.95 kWh 🙄
The graph is from yesterday (I charged about 10 kWh into the car last evening/night)

In winter, I basically have no surplus at all. Yesterday it was only 11 kWh, and the day before just 1.95 kWh 🙄
How many cycles do you manage per year?

DaGoodness23 Nov 2022 16:15So today I also generated 26.7 kWh and my battery was just fully charged. It is currently discharging again and is still at 86%.
Although it won’t last the entire night thanks to the heat pump, I have already saved 10 kWh by reducing grid consumption.
So far in 2022, I have drawn 2,085 kWh from the battery. At 40 cents per kWh, that equals a saving of €646.35 (with 9 cents feed-in tariff already deducted).
