Electrical Usage with Solar Power Generator

June 20th, 2009

This is an example of how a ”solar power generator” may supplement household electrical usage for an appliance or lighting. 

To give you an idea of the potential of one solar panel, pretend that you have just made a 20 watt solar panel and it was exposed to six hours of full sun. Multiply the 20 watts times 6 and you have generated 120 watt-hours of energy.

Do you know your household’s demand for electricity?  Look at your current electric bill to see how many “kWh Used” were you charged.

If you are going to use the solar energy in the example above to power an appliance that needs 20 watts, then you could power it for 6 hours on the energy collected and stored that day. This is where the batteries are used to create the on-demand “solar generator” solution. A battery will store about 400 watts.
