Is there anything on the horizon that might store megawatts of energy? Hydro power can already be used now - pump up the water when there's a surplus of power feeding and release it later. Flow batteries are promising and scale to MWh. en.wikipedia.org That's what you need make PV a replacement for Gas/Coal/Nuclear. I don't see it as an "all or nothing". PV can be a useful part of the renewable mix, together with wind and hydro. Every little bit helps. I don't consider myself to be a PV "missionary", the technology will pay for itself and find its natural way into the market. One can think of PV modules as "chips". Just as the same computing power becomes cheaper every year ("Moore's Law") the production costs of PV modules drop to lower and lower levels. Longevity is also not a problem any more. Yes, there is a decline in efficiency but there are vendors who offer a warranty for 25 years and 80% power level after the end of that period.
