This is a concept I never fully understood. My father even sold all kinds of renewables for ~5 years until 2016, and he just said “Thermal just isn’t worth it” but never really explained how or why. And even now when all Europe is under a strong pressure into deciding how to heat our homes this winter, it seems that no one is still considering thermal solar as a solution.
Heck some governments even decided that it was better to propose PV + Heat Pumps instead of Solar heating

Why?

So basically thermal simply heats pipes with water in them and those are used for heating and hot water. Obviously in winter there usually isn’t enough sun to do this properly and you need to get the energy elsewhere.
Photovoltaic creates electricity, which can be saved in batteries and used when needed.
