While solar power seems to be a form of free energy, after the initial investment for equipment, dont do it! The reason is that in less than one year, the Sun is going to burn out. Without the sun, solar power will not work. You'll spend many thousands of dollars on equipment that will not have any value. Some persons believe that the Sun will last forever, when in fact it's nearly dead now. It's been burning for millions of years, and it's almost out of fuel. Once the Sun burns out, all solar equipment is obsolete, and you'll only get scrap metal value for it, which is little compared to the cost to buy it.
It is likely the Sun will actually burn out before the end of this year.
