Housing Solar Power Rising in Popularity

Remember that the first really big oil crisis of the early 1970? Interest in solar energy really began to take off with visionary people saw the writing on the wall and began to think about the finite nature of fossil fuels. Once the panic had ended, but, people lost attention to solar energy. Residential facilities became less frequent as the recovery took many years to understand and oil was once again abundant and affordable. In recent years, the charm of residential solar energy, once again caught the attention of people because of concerns about global warming and the reality that oil costs and gas prices have been constantly increasing.

 

According to the Solar Energy Industries Association, 2010 was a banner year for solar installations - double the number recorded in 2009. The year 2011 is shaping up to be even better, with more than 66% residential solar energy systems installed in the first quarter from a year earlier. More and more companies are entering the solar energy business, too. The Department of Energy indicates that there has been a large increase in the last couple of years in the number of manufacturers of solar panels and solar systems that produce hot water.

Costs of residential solar energy

The positive aspect of this news is that prices are falling, so solar power affordable to many more people. In addition, the federal government has raised tax credits and some states offer their own incentive, which substantially reduce the recovery time. For owners who opt for a grid tied system, the ability to sell its surplus energy to your local utility will save more money.

Styles residential solar power systems

There are three main types of solar energy: passive, thermal and active. Passive solar homes are houses that are made to take advantage of warm sunlight and are oriented to the south in general, solar, with large south windows and small windows on the north side. Thermal systems are those that heat water for domestic use using sunlight and usually include pumps to move water. Active solar energy comprises solar electric panels, also known as photovoltaic panels that convert sunlight into electricity. A landowner can install a kit of solar panel that will power one device or two, or buy an arsenal that will allow the family to run on solar power.
