With much study and attention to safety instructions in advance, it’s easy to build one’s own PV solar electric system. Without some of the more expensive appliances (electric range, electric clothes dryer, forced air furnace, etc.), a small, efficient house can be fully powered for about $60-70 per month (mostly battery replacements, costs averaged over about 25 years in a relatively sunny area and only with a self-install). And that way, your money won’t be going to the local, government-employed or connected crooks with their fingers in local energy companies.
