Most folks have the “idea” that solar costs lots of big bucks. But the truth of the matter is – solar energy is an investment. Like big power company’s that buy a nuclear power plant. There is a big (one time) upfront investment for the company that will usually pay off later.
You would do the same thing – invest in a pile of components that will become your personal utility. The cost of taking care of your utility is minimal – after the initial purchase. You don’t have any monthly bills – it is YOUR utility. Why is solar worth having? Because it gives you power. The power comes from the sun and goes into your pocket – if you got it. Solar power is nice and quiet – use a night-light to go to the bathroom.
