30% for a system on average. The first 2 kWp certainly 80%, the last 2 kWp rather 10%.a) Usually, you don't calculate with 20% but with 30%. 35% is rather the maximum; here you really have to actively use the photovoltaic system.
When you only get back what you originally put in, nothing is amortized for a long time. For that, you still need an interest rate. The statement "if nothing breaks" says the rest. To the OP: I would decide now based on gut feeling; this is not an investment decision but a pure consumption decision. Considering effort and structural risks, an ETF is always better. But 4,000 euros is rather pocket money, your retirement provision will not be ruined by it or exactly the opposite.With fair photovoltaic offers, you come to an amortization of the photovoltaic system in about 10-12 years, if nothing breaks. After that, you still have the same amount of time in which the system generates electricity for you for free.
