In Germany there is no VAT for solar installations - I'm not aware of any other "subsidies".

We (northern part of Germany) installed 7 KW panels with 10 KW battery for €15K in 2024. My neighbor is installing 10 KW panels with 10 KW battery for €18K this week. So it seems the total costs have not dropped any further in the last 2 years.
