Solar power for the home has made great strides since its early beginnings. Technological advancements have allowed commercially available building materials to incorporate solar cells, which turns them into solar panels that are virtually invisible to the naked eye.

Solar power for homes is supplied through one of two systems. The first is a stand alone solar power system that functions as your sole source of electricity. The other type is a supplemental solar power system which can supply all of your homes electricity depending on sunlight availability, and can utilize the power company grid when solar power is not available.

The same basic parts for generating solar power for homes are used for both standalone and supplemental systems. First, there are the photovoltaic panels, also known as PV panels or solar panels. These are lined with a semi-conductor unit or solar cell which will turn the sun’s rays into electricity. This electricity is routed into a voltage regulator/controller that maintains the current at the appropriate level for your system. The electricity then goes into either a battery backup storage system or directly into your home’s electrical system so that solar power will be supplied after sundown.

Installing a storage system has its pluses even if you’re connected to the grid. Your monthly utility bill will still be less than what you would pay for full service from the power company, but you’ll also have access to power in the event of any outages.

Supplementing or replacing your electricity needs with solar power for homes is becoming easier and more affordable than ever. Some building materials include roofing material, awnings, car port roofing and the edges of the panes in your windows. This type of solar panel is called Building Integrated Photovoltaics. When used in roofing material these panels offer the same level of home protection as asphalt shingles while functioning as a solar panel.

One of the greatest obstacles to using solar power for homes has traditionally been the up-front expense. Now, however, there are avenues to offsetting that expense. Government grants are available which go a long way toward subsidizing your household’s conversion to solar power. Federal rebates for solar power installations can vary year from year, and each state that offers one has its own incentives ranging from additional rebates to offering low-interest rates to finance green projects.

Aside from reducing your homes environmental impact, perhaps one of the greenest returns you will see will be in your utility bill which you can reduce or eliminate through the use of solar power for homes. Most utility companies even have a metering program that enables you to sell the excess power generated by your solar power system to the utility company, now hows that for green!
