Solar / Photovoltaic from an economic perspective

Verivox shows me a price of 20.15 cents (for 7000 kWh) plus an annual fee of €86 for the "grüne Welt". (without any bonuses) You are right, however, that with the tariff without a basic fee at Maingau you come out a bit cheaper. But it is one of the few that currently offers it that way. If they charge a basic fee in the future, it will no longer be worthwhile.

OK - I had included the bonus in my calculation. However, it is quite interesting to see how the "advertising bonus" affects things. 1. Completely different prices per kWh 2. Completely different prices for the base fee (sometimes massively higher with lower kWh prices in the "bonus area") 3. Different total prices in the first year with the same provider (logically the tariffs have different names with different terms) However, overall the tariffs with bonus are slightly cheaper in the end - despite higher prices per kWh. So I will also check the second page when switching in the future (whether normal or heat pump electricity). I officially take back the statement "... you are messing with the wrong person" - you never stop learning. However, even in the example calculation with the reported 5 euros/month for the additional meter, I am still slightly cheaper: 0.2013 + 0.0119 (83 base fee / 7000) = 0.2132 - 0.19 = 0.0232 * 4000 = 92.80 euros - 60 euros base fee = 32.80 euros savings respectively. However - and I wrote this before - if things turn around sustainably, I also have no problem dismantling the second meter and running everything completely on the household electricity.

Who takes the advertising bonus must actually necessarily switch after the first year, otherwise they have a rather expensive tariff. Those who forget then pay a lot for it and the electricity providers probably count on that.

We decided on a tariff without a bonus last year because we didn’t want to switch constantly. (hatten wir uns zumindest gedacht) Now our previous electricity supplier is raising prices from 21.x cents to 29.65 cents in December and the basic fee is almost doubling, which forces us to switch again

We decided on a tariff without a bonus last year because we didn't want to keep switching. (at least that's what we thought) Now our previous electricity supplier is raising the prices from 21,x cents to 29.65 cents in December, and the basic fee is almost doubling, which forces us to switch again

So THAT is almost outrageous. They must have seriously miscalculated to implement such massive price increases now.

kW or kWh?

I still owe you the answer: kWh of course

By the way, I just picked up from the mailbox the request from Westnetz GmbH to specify our self-consumption. Reason: Calculation of the Renewable Energy Act surcharge on self-consumption (of self-produced electricity).

I was aware that self-consumption is subject to VAT, but that now the Renewable Energy Act is also being charged, I find quite ... . The only consolation – as I understood it – is that a reduced Renewable Energy Act is charged. Soon, probably, one will also have to pay VAT on vegetables grown in one's own garden.
