> The European electricity market, the Germany is connected to, prices electricity (or priced last time I checked, there might have been changes), like this (over symplified, so please read up the details yourself): I keep trying to say that this/market price isn't really relevant. Nobody would invest in solar if it only produced as much as it does in December whole year long. If you overprovision enough that solar alone could satisfy any of meaningful proportion of total demand during winter that mean that prices during sunny summer/spring days would be approximately 0 which again makes investment unattractive. > TL/DR: Exchanges, aka the market, ignores fix costs while opertors don't. Perhaps. I don't see how the first half of this sentence is particularly relevant to this conversation and the second half is something I keep repeating over and over again. > Honestly, if you fail to understand that crucial market mechanism Well yes if you add gas, coal, wind etc. to the equation it changes this but that wasn't part of the initial argument. If you have more or less constant demand during the whole year (or especially if demand in winter is higher) solar capacity needs to be balanced out by gas/coal/etc. which is far from ideal. That doesn't seem to be likely to change in the foreseeable future (and to reiterate I'm talking specifically about the northern half of Europe.
