Hello,

I would like to know your opinions on the topic of photovoltaic systems.
The plan is for a house with 140 sqm (1507 sq ft) with a south-facing roof.
Is financing such a system worthwhile?
What are your personal experiences in this area?
Do you have to feed the electricity into the grid, or is it allowed/possible to use it yourself?
Are there any special incentives or subsidies available?

What disadvantages does installing such a system have (please don’t mention “appearance”)?

I meant if you have fully utilized your roof.

From 10 it changes from private to industrial – with higher taxes

There’s no reason to stop at 10 kWp if you could clearly go higher. Above 12 kWp, the higher taxes become less significant.

Well, for us the house roof (south) plus garage roof (south) is fully utilized at 9.9 kWp, so I have never really thought about exceeding that 🙂
