Solar power extraction is not financially feasible at the moment. Definitely not for general application. The cost far outweight the savings. I have actually enquired for a working solar panel. A basic solar panel with lithium battery cost roughly around 60k. Higher capacity will cost more than 90k. I think it produce around 100 kWh on a good day.
Another way to extract the solar power would be to have the solar panel installed on a satelite. The satelite would then convert the energy into microwave before blasting it back to earth.
