There are different kinds of solar power generation, the photovoltaic panels that generate electricity directly that we all know and love, and thermal solar. You’ll commonly see a small-scaled version of this used on homes as a hot water system.
Scale it up though and you’ve got a system that can generate energy 24/7, as long as you’ve got enough thermal mass, and sunlight.
Hmm, for me it just says “This item is not available for purchase in your region”, not sure I know that currency.
