Most of us cannot feasibly afford to install a full solar power system into our homes. Energy Refuge suggests starting small. One solar panel and a sealed battery would hold about 400 watts of electricity. You will also need a charge control, power inverter, and a voltage meter. That is enough to run some of your small appliances, and will offset the cost of the solar panel. Here is a tutorial, put together by Energy Refuge on how to build a basic solar power generator.
If you are not comfortable starting from scratch, then have a look at this kit, by the ‘Go-Solar’ Company. Reasonably priced especially when you consider the savings on your electrical bill. Five hours of sun per day and a 20 watt solar panel will give you 100 watt-hours of energy. To store more electricity simply purchase a larger battery.
