Offer for photovoltaic system including storage - Storage yes/no?

Your statement is too general. I know many, and I am also one of those where the highest consumption takes place in summer (without heat pump). In winter, unfortunately, there is not much to be done with roof systems, and the battery will/should almost always stay fixed at 50%.

So we have our battery for the transition period? Why should it have its main use in the summer?

We for the evening hours and night, no matter the season. Only in winter, not much comes of it anymore, and the battery then remains at a healthy charge level and receives manual cell balancing every few weeks.

Yeah, yeah. These are again the enthusiasts who read a bedtime story to every battery cell and spend 2-3 hours daily in summer rerouting the energy so that the storage is empty again the next day. Charging the car, heating 2,000 liters of water, cooking 500kg of jam, etc. Then it might "pay off"... Otto Normal, who leaves the control to the automatic system, has a storage that is always full in summer, always empty in winter, and somewhat sensible during the transitional period, which he paid very expensively for...

The same crazy debates are also held in the e-car fanb... sorry, in the e-car forum... everything is great, the manufacturers do everything right, if in doubt the user is too stupid, unwilling, incapable, or simply a right-wing radical climate change denier...

What is often forgotten in the calculation is the acquisition price financed at 5-6%, depreciation, ongoing maintenance costs, and of course reserves for repairs/replacement...

So currently it gets dark around 7:00 PM. In my somewhat larger barn, I have LED floodlights for sufficient lighting. In the past, they were halogen floodlights with corresponding power consumption.

Today, the LED floodlights run for free, as they are powered from my [Photovoltaik Speicher]. Just as an example.

At the moment, I only draw about 50 watts from the grid during the day! And until mid-November, it won't be much more than that.

Without storage, I would feed in more, but also have significantly higher grid consumption. Personally, I prefer to save on grid consumption rather than feed in.

Those who like to feed in for 8 cents can just leave out the storage.

Anyone who gets a storage system from the solar installer should rather calculate what the kWh actually costs. Thanks to that, the storage (usually) is way too expensive.
