1483€ per kWp | CanadianSolar 11.48 kWp and SMA inverters

Much too expensive! And don't get a Senec storage. I tell you this as an owner of one

Thank you very much for your assessment - also regarding the Senec storage. This is already the second time I have received this feedback....

The calculation is quite simple.

I consume 5000 kWh of electricity per year. Thanks to the electricity price cap, the kWh now costs 40 cents. So I have to pay 2000 euros annually for the electricity consumed. Clear so far. One person has a little more, another a little less consumption.

A photovoltaic system 10 kWP with storage for 15,000 euros means that I can reduce my electricity purchase from the energy supplier by about 70 percent with some planning. Thus, my annual savings amount to 1400 euros plus possible feed-in compensation. That won’t be much, maybe 200 euros per year.

So the system will have paid for itself after 10 years. The difference is, I do not pay the 1600 euros to the energy supplier but to myself. I do not care whether I have the 15k now in the bank or on the roof.

For me, the electricity supplier now debits only 35 euros per month instead of 120 euros. And any electricity price increases basically don’t affect me at all.

yes, according to some calculator. Unfortunately, reality looks a bit different.

You will have many days, even with your large system, from mid-November to the end of February/early March, where you will be glad if you get a total of 4-5 kWh per day from the roof at all.

Unfortunately, I cannot confirm that. Yesterday, 39.4 kW were produced during the day, the day before yesterday it was 32.5 kW. Sure, there were also a few bad days in December where it was single-digit, but not too often.

Show a screenshot of the app, then it can be understood. Or directly the statistics from 2022, how many full cycles did you have?

as you can already see in this thread, 15k€ for 10kWp + storage is at most just a pipe dream. In the current reality, you pay 2 to 2.5 times that amount for such a system. Edit: the new processing time is simply way too short...

I am also a fan of photovoltaics, but some things have been calculated very optimistically (except for the significantly too low feed-in tariff). Probably no one in Germany achieves 70% self-sufficiency with such a small system. And 15,000 is simply not possible at the moment. It's best to calculate without a storage system, then you might achieve a payback period of 10 years. With storage, it is currently rather difficult.
