There are actually two kinds of residential solar power systems, and these are the grid tie system and the stand alone type of solar power system. The grid tie involves the power grids being connected into the electricity grid. On the other hand, the stand-alone type has no connection to the electric grids. Many prefer the grid tie as it is less expensive than the stand alone power system.
One important benefit of solar power systems is that they lead to substantial savings on electrical bills. In fact, there have been experiences of some residence owners being able to save up to 75 percent of their power bills. Likewise, there is possibility of your residential solar power systems being able to create surplus power. And if you are using the grid tie, certainly you have the option to sell the excess power to utility providers.
Lastly, the most significant benefit of solar power systems perhaps is how they greatly contribute to the lessening of pollution. With home solar panels and other sun-powered devices becoming more popularly utilized, hopefully the demand for electrical power becomes less and fossil fuels will be utilized less frequently as well.
