The building block of solar systems is the photovoltaic cell. It wasn’t that long ago that these were curiosities that showed up at the science fair running a small motor. Now banks of them on your roof or other exposed area can power your home. Electricity produced by the cells typically charges batteries which then pass through an inverter to make the AC required by the lighting and appliances in your home. The batteries provide backup to supply power when there is no sunlight. How exciting is this – making your own power?

A solar power system can come with an initial high price tag. It may take years before you recover the cost. However if your state allows feeding back to the grid and with tax incentives and rebates your system will pay off much more quickly. A solar electricity system will never run out of fuel nor will it increase our dependency on foreign oil. But don’t think about the costs or that you will be saving money down line, think of it rather as investing in your freedom by starting your research of solar electricity systems today.
