Hello everyone,
After several inquiries and offers, I now have what I consider the most cost-effective offer (see details below). I am still unsure about the "necessity" of the battery storage. I believe there is no clear "yes" or "no" answer here.
Based on your experience and what is known so far, is the payback of the battery storage guaranteed within the warranty period? I don’t think the battery will make you rich or poor, but you can make the most sensible decision now.
How do you evaluate the offer and the components in general? Does anyone perhaps have a comparable system and experience to share?
Photovoltaic system 11.9 kWp with 9.6 kWh battery storage
Total price just under 24,500 € (euros)
Best regards

Buchsbaum26 Sep 2023 22:45What do you want to see there?
18 Trina Vertex 405 modules, heat pump at 120 euros each, the Huawei battery 5000, the Huawei Sun 6K inverter cost 1000 euros, roof hooks 80 euros from classifieds, rails from classifieds 150 euros, cables 100 euros, and the smart meter 200 euros. 1000 euros for the electrician and 500 euros for miscellaneous items like screws, nuts, cable ties, etc.
Just under 10,000 euros in total. I installed everything and laid the cables myself. I used my own scaffolding. The electrician connected everything to the meter cabinet, installed the smart meter, commissioned the battery, crimped the plugs for the strings, and registered the system. Grounding cable and RCD (residual current device) were included.
Any questions?
Back then, everything was subject to VAT.
Today, you can get the modules for 100 euros each, the battery and inverter are also somewhat cheaper. On the other hand, rails and cables are a bit more expensive. It balances out.
I’m a tradesman; I can cut the tiles myself and also lay the cables. I had to run 30 meters (100 feet) of 5 x 6 mm² cable from the meter cabinet to the inverter, as well as the data cable. And there were 25 meters (82 feet) of solar cable from the modules to the inverter—4 cables for 2 strings. I also had to do some trenching and bury the cables in the ground. Naturally, inside an appropriate protective conduit.

Buchsbaum26 Sep 2023 22:57I have checked.
The Huawei system is available from elektroland24 for 8,662.00 euros. This is a great price for a 10 kWp system with a 10 kW battery storage. It is three-phase, including a smart meter, a dongle, and all necessary components.
Of course, when the solar expert consultant comes and quotes 28,000 euros, they earn about 20k for two days of work. But I can do this myself.
Scope of delivery:
25 x Trina solar panels 435 heat pump glass-glass TSM-435NEG9R.28
1 x Huawei hybrid inverter SUN2000-10KTL-M1
1 x Huawei battery storage system LUNA2000-10-S0
1 x Huawei smart meter 20022249-001
1 x Wi-Fi dongle
8,662.75 euros in a special package offer.

Buchsbaum27 Sep 2023 06:31Yes, it was more expensive.
For the price, I only got 7.2 kWp and the significantly smaller Huawei Sun 6 KTL M1. Nevertheless, the price from Elektroland is still very good. Maybe I will install an extension system later.
The funding portal is of course no longer accessible, the funds ran out after two hours. What nonsense.

RotorMotor27 Sep 2023 08:06@Buchsbaum, how many cycles or kWh do you get per year from your storage system? Ideally with a screenshot from your portal. 😉

Ok, costs without the tank have been requested, I’m curious to see the results 🙂Hello everyone. The tank costs 5800€.
How can I best estimate when it will approximately pay for itself?
Good luck
