I still feed 2500 kWh into the grid with my system of 7.2 kWP and 10 kW storage. Brings me 200 euros a year.
Can be forgotten.
Plus according to the current status 3200
Does not add up.
4500 x €0.08 per kWh are 360 euros feed-in tariff per year for me. 7200 euros feed-in tariff in 20 years. Nothing pays off comfortably there.
Why not? You can’t just assume the 10,000€ you paid with storage. How much would it have been without? And how much feed-in tariff would you have if you had spent the 10,000€ only on photovoltaics?
And how much (more) direct consumption, which you completely omitted in the calculation?
At first glance, it looks like your photovoltaics with storage fully pay off. But it is hard to understand as long as you calculate like a milkmaid.
And another mistake in reasoning:
Just because your photovoltaics with storage pay off doesn’t mean that photovoltaics without storage do not pay off. They can even be more profitable, to put it mildly.
But then you would have to “give away” your hard-earned electricity to the evil DSO :rolleyes: *
I have 10,000 euros in my account. Until last year, I had a 1800 euro electricity bill. My system cost 10,000 euros. Now I pay only 60 euros for electricity. That is 1200 euros saved per year.
Makes a saving of 24,000 euros in 20 years.
Think about it again. My year has 12 months.
*PS: By the way, you don’t have to claim the legally guaranteed feed-in tariff for 20 years. You may sell your electricity anytime to the highest bidder.
