Construction costs are currently skyrocketing

It is simply not politically desired. Just like many things are only politically motivated.

At the beginning of September, apples from New Zealand are cheaper at Edeka than the apples from the local supplier just a few kilometers away.

A machine factory is 20 km away from me. But if a spare part breaks, I cannot get it from the factory. Recently, a machine part was delivered by special transport from Finland. 2000 km away.

Normal? Reason? Environmental protection? No one cares.

There were once attempts in Switzerland, or rather prototypes, with compressed air storage systems for private households. 25 kWh storage capacity. That was already 10 years ago.

A complete scam package in my opinion, which faces a massive risk of insolvency. Senec also has to buy the "cloud power" on the market for the winter ... that could get interesting. It wouldn't be the first "cloud" to go bankrupt. Then the prepayment is gone, leaving at least a storage under criticism in the private customer's possession.

I would agree with you if Senec itself were a small company responsible for everything. But since EnBW, one of the largest energy companies in Germany, is the parent company behind it, I worry less about insolvency :p

Back to Topic

Lumber is readily available with us, prices are even slightly decreasing.
Roof tiles are very difficult or not available at all (e.g., Fa Erlus).

So I definitely don’t want Senec junk standing in the basement or anywhere else. Weeks-long forced shutdowns of the systems and very expensive to purchase. Of course, the Senec Cloud only works with Senec devices.

3 exploded houses are certainly enough to thoroughly ruin the reputation for now.

Otherwise, there is no power cloud that makes sense even for the small photovoltaic owner. Large systems go into direct marketing anyway, which looks different again.

A factor of 2 would be fair for both sides. I feed 2 kWh into the power cloud and get 1 kWh back in winter.

Unfortunately, you don’t hear anything about pumped storage power plants or compressed air storage for small consumers. It’s all just hot air. And without the Chinese, we wouldn’t even have battery storage up and running yet.

Have you dealt with the topic or is this just another pub talk slogan? It’s not news that storage systems are generally not entirely safe. Just look at how many phone batteries and now also e-bike batteries regularly catch fire. And we don’t even want to talk about Teslas ;)

3 out of about 80,000 systems is not exactly a rate that worries me. My car could catch fire, I could be run over by a bus, or something else could happen.

The forced shutdown was annoying, yes, but Senec compensated with more money than I saved with a functioning storage during that time. And I’ve often heard that the storage is expensive, but I can’t confirm that for myself. It also depends on which solar installer you buy from. Mine wasn’t cheap price-wise, but including subsidies, it was acceptable in my eyes.

Also, it’s not even clear whether the storages were actually responsible for the explosions in the houses. :rolleyes:

Due to the Senec incidents, I replanned and installed my inverter and the storage system in a technical room of an outbuilding.

That was also a good decision, because the storage system occasionally hums or buzzes under certain conditions. However, this is supposed to be completely normal. I also do not want such noises in the house.

Otherwise, the Senec storage system is very expensive, at least according to an offer I have. And they didn’t even want to use the standing scaffold from the roofer. Instead, they only wanted to install it on the house roof, which was completely nonsensical because there was a perfectly oriented south-facing roof on the barn next door. They didn’t want to do that. I did not find any of this very good.

As said, do the full cost accounting. and then present it transparently here. I think you are making the numbers look better for yourself, it may be that I am wrong. But I don’t think so, as on other boards real experts calculate back and forth and all come to the same conclusion.
