Photovoltaic power is antithetical to solar thermal power.   Photoelectric power converts sunlight “directly” into electricity. There are no moving parts. Lots of sunlight and cold climates are ideal for maximum efficiency. On the other hand, most solar thermal power “indirectly” generates electricity, and infrared energy is the driving force while hot, dry climates are ideal.

The semiconductor industry is inseparable from photovoltaic technology, and solar panels are applicable to power production for residences, small businesses, and niche markets as well as to large-scale utility power plants. Niche markets include garden lights, traffic signs, hand held calculators, and many other low energy requiring devises.  Yet, solar thermal power is limited to large-scale utility power plants only.  The differences are stark!
