Solar Power In Homes

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.

There are two ways that solar power for homes is supplied. These are off-grid and on grid or net metering. A stand alone solar power system acts as the sole source of electricity for your home and is off the grid as such. Alternatively, supplemental solar power systems, can supply all of your homes energy depending on sunlight availability. When sunlight is not available, your home can use energy from the power grid.

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.

If your home is connected to a power company grid you do not have to install a storage system, but it does have its advantages as it will help to further lower your monthly utility bill, and it will make power available to you during a power outage.

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.

Any green project will reduce the environmental impact your home has on our world. However, the greatest pay off will be a reduced or even eliminated utility bill each month. Quite a few utility companies have a metering program under which you can sell excess power generated from your home solar power system to the local utility company, in effect making your meter run backwards. This helps more than just you. The excess electricity can be used by other customers of the power company and can reduce the reliance on fossil fuels that power companies currently use.
