A series of inquiries to residential PV installers has revealed a tough consolidation phase in Germany’s solar installation market. With an increasing number of installers offering solar arrays at very low prices, competition is intensifying as companies vie for fewer orders.
Weirdly enough, Germany installed more PV this year than ever before, and we even almost met the goals for the entire year in the first half: https://www.energiezukunft.eu/wirtschaft/energiewende/jahres-zubau-ziel-fuer-die-solarenergie-nach-einem-halben-jahr-fast-erreicht
I think the main issue is here that everyone and their uncle started to bolt solar panels on buildings, so the installer market is flooded with supply, but the demand can’t keep up.
