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 basic components to generate solar power for homes are the same whether you opt for a standalone system or a supplemental system. The key component is the photovoltaic panels, commonly known as PV cells or solar panels, these panels are lined with a semi conductor or solar cell that turns the rays of the sun into electricity. This electricity is then routed into a regulator/controller that keeps the current at the voltage/amperage level your system is designed for. The electricity is then routed either into your homes electrical system or into a battery array or storage system that will keep that solar power available when the sun goes down.
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.
It is now cheaper and simpler than ever before to reduce or eliminate your need for outside electricity by using solar power for homes. Several types of building materials include awnings, roofing materials, car port roofing, and edges of window panes. This kind of solar panel is known as Building Integrated Photovoltaics. If used for roofing material, such panels provide the same measure of home protection as do asphalt shingles, even while they function 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 home's 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 how's that for green! Net metering is a good idea in terms of environmental impact because it gives individuals an incentive to sell their electricity to the power companies which can then be sold to other users. This can reduce the power companies reliance on fossil fuels that are thought to cause many of the environmental problems we currently face.
