There are definitely economics of scale. They are just not visible in Germany due to outdated building and policy practices. > I'm not talking about prices, which may incorporate subsidies, permitting costs, taxes such as tariffs, transaction costs, lawsuits against non-performing building contractors, and market inefficiencies such as homeowners not having access to the zero-marginal-cost excess power that can be produced on sunny days for regulatory reasons. Every single thing here is policy failure by German government.
