Solar energy (the correct definition is Photo-Voltaic power) is there for everyone’s use. The panels
used today are much more efficient than even ten years ago and the price has come down immensely. Panels used today can even draw in energy in a night with a full moon.You can attach them to almost anything that is facing south and you don’t even have to flip a switch.
Want “Solar” power at night then just add some batteries and they will store it until you need it. The panels only maintenance is a washing every once in a while to get rid of the dust.
