ᐅ Costs of Photovoltaic Systems with Energy Storage

The commissioning (on paper) is often scheduled for the new year since the feed-in tariff is guaranteed for 20 years plus the current year.

I think he mentioned something like that... the system would probably be finished by the end of December if everything beforehand goes as planned.

The photovoltaic forum takes the opposite view. The feed-in tariffs fully finance the system (provided the production costs are not exorbitant), and self-consumption is considered just the cherry on top.

Hmm, I don’t quite agree. My system, 6.25 kWp east/west, generates 50% of my annual consumption...which is also a significant part of the system’s payback. If things continue like this, I’ll break even after 7 years at the latest and will be making a profit from then on 🙂

I just followed up with Clensolar. The salesperson said it’s due to increased material costs. Their suppliers have simply raised prices significantly. However, he still believes they remain very competitive.

Based on my experience with those guys, I believe that too. I’m glad I signed the contract last December 😀

The photovoltaic forum has it the other way around. The feed-in tariff fully finances the system (if the production costs are not excessive), and self-consumption is considered the bonus.

In the end, it doesn’t matter what finances the system. The feed-in tariff is an income, while self-consumption is a saving. Per kilowatt-hour, the income is now significantly lower than the saving. Therefore, every kilowatt-hour used on-site is financially much more attractive for people installing a system today than every kilowatt-hour fed into the grid. For registrations in July 2021, the feed-in tariff is 7.47 cents/kWh. Those who buy electricity cheaply pay around 20 cents net/kWh for their power. The ratio changes month by month—so you need to consider how “historical” a post is or the situation from which it was made.

Hmm, I’m not sure. Increasing my consumption would improve the return on investment. That might be true mathematically, but to me, payback means something different.
