ᐅ Costs of Photovoltaic Systems with Energy Storage

Let me know when it’s ready. Hopefully, there will be a forum discount then.

I just received my first rough quote from Clensolar (after all the recommendations here). I’m a bit disappointed.
Yes, you said they’re not the cheapest, but at just over 1,600 EUR/kWp net for 10.65 kWp, I can’t really be satisfied, right?
My really bad offer from Solarmeisterei was for just under 10 kWp, but included a battery storage and the very expensive LG modules—27,000 EUR net versus now 17,000 EUR net without storage.
Maybe it’s because Berlin is actually too far away?

I think I’ll put the photovoltaic thing on hold for now.

Sent you a private message. I received a quote from them at about 1,400 € gross/kWp without scaffolding. And it’s also near Berlin (40 km (25 miles) south).

Hmm, I’m not sure. The return on investment would increase if I raise my consumption. Mathematically that’s correct, but to me amortization means something different.

Of course, it’s not about increasing consumption, but about replacing purchased energy with self-generated energy. This can be well calculated in advance for the investment decision and included in the amortization calculation as the difference compared to the opportunity costs of the photovoltaic system.

Opportunity Costs

What kind of opportunity costs are involved with a photovoltaic system?

Regardless of all calculations, I believe using photovoltaic panels is the way forward, if only to make progress. For us, it was a matter of mindset. When we decided to install them, we didn’t even know there was a financial incentive. Our motivation was purely ideological.
Of course, we were happy to receive payment for it as well.

Soon, it will be mandatory anyway. I am sure of that.

I also support environmental and climate protection. From a (social) ideological perspective, I find the idea of decentralizing energy supply somewhat appealing. However, I am not entirely sure whether equipping all private homes with photovoltaic systems, regardless of origin, and energy storage devices, regardless of technology, truly supports the first two goals. I am not saying that it doesn’t, but I do not claim to know all the data and facts to judge this accurately.

From an organizational standpoint, centralization or concentration is often significantly more efficient due to synergy effects and economies of scale than having many amateurs handling things they think are great, especially when snake oil vendors receive good sales training. I’m just saying, the power cloud.

I’m curious to see how this will be implemented. If it really becomes mandatory for new buildings (which I fully expect), it will have to be affordable. That leaves only substantial subsidies and/or passing the costs on to the rents.
