    Yeah, but PV is dirt cheap nowadays. Also

    degrade over a few years.

    If by “few” you mean like 30-50 then sure, they degrade. But it certainly beats anything with a spinning turbine. Or anything with moving parts really. PV is purely solid state physics, you can’t get more longevity than that.

    If the capacitance of the system is not enough to hold the produced power then an electrical failure will occur, so you must also include large commercial and industrial batteries

    That’s not true. You can also simply turn PV off. The inverters only run when they sense 50 Hz on their output terminals, it’s easy to have them turn off when it’s 50.2 instead. Basically all big powerplants follow that rule already, ordered by things like shutoff time etc.

    Funny that you specified in the desert. The appeal of PV is not only that it’s cheap and easy, it also scales down to small investments and local power generation. If base load actually becomes a problem concentrated solar power will be relevant. But for now, slapping a few solar panels on your roof just makes sense.
