ᐅ Photovoltaic System: Costs and Savings Potential – Experiences?

... and a huge consumption. Saving 700€ through energy use means at least 2500 kWh in a simplistic calculation (i.e., assuming self-generated electricity is free). You first have to produce and also consume that amount during the specified time of the year.

Is it already clear whether there will be any significant changes for photovoltaic systems starting in 2021? I haven't studied the topic in detail yet, but with the VAT reduction, there should be more available capital again.

Are there any reasons to install it quickly in 2020? The house will be completed in July, and we have made preparations (4 photovoltaic cables (1x4mm2) in conduit and 16mm2 grounding cable, plus an extension of the meter cabinet, prepared for a system with two strings). The pitched roof has a 38° slope and faces south; we have not installed any skylights.

It is not clear exactly when the tipping point will be reached, but it will likely happen by the end of the year. The government has only announced that a follow-up regulation will be introduced, but has not yet specified what it will look like.

The removal of the cap is part of the economic stimulus program. Measure 38.

I would act as quickly as possible. The feed-in tariff keeps decreasing.

Ok, thanks. I’ll look into it then – has anyone had good experiences with a solar installer in Berlin/Brandenburg?

When the cover falls, on what basis is the electronic ballast (EVG) then determined? Are there already calculation models for this?
