1483€ per kWp | CanadianSolar 11.48 kWp and SMA inverters

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 for such a system.

Just for your information, there is now the Titan LiFePO4 Lithium 200Ah and 51.2V, 10kWh for about 2500€ or 50kWh for about 12k€. In the generally well-known photovoltaic forum, many have already ordered it and 1-2 have also put it into operation. If it turns out that they are worth what they cost, the calculation for storage amortization will look very different than 7-10k€ for a 10kWh storage.

And 15,000 is simply not possible at the moment.

With DIY it is easily possible, you can almost get double the kWp on the roof without a storage system.

Just for your information, there is now the Titan LiFePO4 Lithium 200Ah and 51.2V, about 10kWh for around €2500 or 50kWh for about €12,000. In the probably well-known V0P forum, quite a few have already been ordered and 1-2 are already in operation. If it turns out that they are worth their money, the calculation for storage amortization looks very different than €7-10k for a 10kWh storage.

oh dear oh dear... no one disputes that it might look different in the future or that you can get cheaper with DIY solutions. You just have to accept that this is currently (!!!) not a solution for the average person and stop posting the same nonsense here over and over again.

The users are overwhelmed just by evaluating the offer alone; how realistic is it that anyone comes up with the idea to install the photovoltaic + DIY storage themselves?

That the turnkey builders faction gets nothing done is well known. But then please don’t complain about it being too expensive and taking too long.

In the face of skilled labor shortages and supply bottlenecks, it is becoming difficult even for top earners to get anything done.

Everyone should already get used to either pitching in themselves or having good connections. What you can’t do, you can learn.

In the GDR there was a nice greeting phrase and everyone knew what it meant.

Forum goes?

That was like a magic word that suddenly opened many doors.

I have received another offer. It's incredible how much the prices differ.
Net price per kWp is 1,776 EUR (for 15.58 kWp).
Offer 1 has already been partially referred to here as a rip-off, so what will be said about this offer?

Are the registration with the grid operator and the final commissioning included? The delivery situation seems to be easing again, both inverters and modules are again available with a short (3-6 weeks) delivery time. Prices will then also normalize.
