ᐅ Evaluation of Photovoltaic Proposal

The offer is about 8,000 to 10,000 euros too expensive. What are the electrician costs of 3,000 euros for? Surely not just for the 2 hours of work on the meter cabinet.

That’s simply the price charged by a solar installer. They build systems at that price. Given the shortage of providers, such prices can be enforced.

Try offering the solar installer to buy the components yourself. Then they won’t install them.

I also received great offers from various solar installers who insisted on installing Fronius inverters combined with BYD batteries—and only that system. Unfortunately, the price was very high at the time, and nothing could be delivered. I then implemented it myself with the Huawei system.

Good idea to remove the wallbox for now. I think it makes sense, who knows what will come in a few years.

As long as you don’t have an electric car, which is usually charged in the evening or at night, a storage system—especially one of this size—makes absolutely no sense.

By the way, the next generation of electric cars could be the one with efficient batteries that completely replace the need for a storage system.

These already exist today. All the new ID models from VW with the 77 kWh (77 kWh) battery can do this – however, there is still a lack of compatible hardware selection like wall boxes, etc.

Are German components, such as inverters from SMA, not an option? If only a small additional cost is involved, I would always prefer German or at least European components for the benefit of all of us.

We are harming ourselves economically by purchasing even more Chinese products, which then can be offered at even lower prices due to economies of scale.

A reliable battery enables a range of more than 1,000 km (620 miles) according to WLTP and charges from 10 to 80% in under 30 minutes. Japanese companies are working on this; Toyota aims to have solid-state batteries ready for mass production by 2027. The batteries that VW and others are currently installing in their cars can best be described as early beta versions.

It’s bad enough that I’ll be getting one of these as a company car in just a few days...
