There is a great deal on a solar system from
Harbor Freight Tools - Quality Tools at the Lowest Prices. It has 3 15 watt panels with a stand to hold them, a charge controller that has a built in voltage meter and outputs for 3,6,9 and 12 volts. It also comes with an adapter cord that will plug into most battery operated radios etc. It also has 2 12 volt 60 watt lights with cords. Couple this to a couple of 12 volt deep cycle batteries and a power inverter and it will provide basic power needs. This is not a large system, so powering high wattage things will quickly discharge the batteries faster than the panels can charge them. It will provide for basic needs. All solar panels burn in after a period of time and loose some capacity. The Harbor Freight system will loose up to 10% of their charging capacity over time. The systems costs $200.00. I bought two of them. Some people say they are cheap and not as reliable as the higher cost panels. I didn't have the money to buy the higher priced panels, so I'm hoping these will hold up for me. I've hooked up and tested mine and they work fine.I read on another thread about a guy who has used the system for a while and it performed pretty good for him. A couple people said they had problems with the charge controllers over time. I bought a 7 amp controller for $20.00 as a back up in case the controllers that came with the system go bad. One 7 amp controller will handle all 6 panels if need be. If things don't go south to quickly, I plan on buying one quality 80 watt panel to add to my system.
