There are hardly any components for photovoltaic systems available now. Long delivery times or not available at all. Plus sharply rising prices, just like everywhere else.
Not to mention the capacities of solar companies, electricians, and installation companies. There is hardly any progress in expansion. At least not that fast.
On top of that, all the dependencies again. Hardly any German photovoltaic module production, inverters, etc. Everything depends on Asians.
At the moment, we can do almost nothing. Extreme energy prices combined with no more available supply chains.
