Both of them require high tech to produce, now that you have to consider things like quicksilver emissions limits when setting up a plant. Measuing parts per billion and tuning the process to minimise emissions is high tech. But that's a distraction. The key difference is that operating a coal power plant involves a logistics chain from a coal mine in a desert in Australia, and operating a PV plant involves wiping dust from the panels. One global escalation and the logistics chain is in trouble — while the panels will still be there.
