The problem of solar power i well known. No sun -> No Energy. In my mind the future of energy supply is not solar power.
Your two opinions are subjective and one-sided. Solar energy could realized de-centralized generation which is a different pattern from thermal stations. Your own rooftop is your own power sation of electricilty.
Even solar powered vehicle are put into market now. Don't be surprise, we already innovate lots of used golf car with solar roof top. Golf car would not work on cloudy days. Conversely, the sunniest days are golf car are moving around frequently when the solar modules are providing battery with the most power.
The issue here is solar powered security lights. Running solar panels that track the movement of the sun, and are installed in California are a different matter. A large enough array located in the UK, backed up by banks of ex submarine batteries are also useful, at a price.
