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?

During the planning phase of our new build, I naturally also looked into the topic of photovoltaics. Thanks to the many posts here in the forum (thank you for that!!), I concluded that I would rather invest the money in maximizing photovoltaic surface area instead of splitting it between photovoltaics and storage. Since our roof has only a 22° pitch, I want to cover both the south and north sides. Unfortunately, the chimney sweep insists on a ladder on the north side, which means three fewer modules can be installed there. Still, there is space for 67 modules, or 26.8 kWp.
However, since our budget is limited and economic feasibility also influences our decision, I decided to assemble the system myself, with the help of two experienced friends. We can use the scaffolding, so no extra effort is needed there. Conduit from the roof to the main distribution board is already installed.
I have now ordered the following components:
Solar module Jonsol JSM108-400-Fullblack 67 pcs.
Rated power: 400 W, tolerance: 0/+3%, MC4 connectors
Cell type: 108 monocrystalline half-cut solar cells - sorted black
Frame color and foil: black
25 years product warranty
25 years linear performance warranty
KBE solar cable 1x6mm² to 16mm²
Burial-rated and higher water resistance
SolarEdge Power Optimizer P850 34 pcs.
Two modules connected to one optimizer
25 years product warranty
SolarEdge SE25K 1 pc.
AC rated power: 25,000 W, transformerless, three-phase
12 years product warranty
GAK 1000-3R-X-C-PC-1.0 1 pc.
Includes DC surge protection type 2
SolarEdge Energy Meter 1 pc.
Includes 3x current transformers 70 A
Mounting system Sunavi Systems
Multi for tiled roof including Marzari metal tile Grande 280
Modules mounted vertically, system design according to DIN 1055
Commissioning and documentation 1 unit
Preparation of documentation for registration and commissioning of the system with the respective grid operator
All together €19,991.00, or €745.93/kWp
To be fair, I have to mention that the offer came through a contact of a friend who installs large-scale systems and naturally has good equity conditions. He still makes a profit, of course.
This is just to show that it is definitely possible to realize reasonable acquisition costs for a photovoltaic system. Clearly, a considerable amount of own work effort is involved in this case. But if we add about 5k on top for two days of installation labor, we are still well below 1k/kWp...
