Solar Powered Systems - Understanding The Basics Of A Home Solar Power System
The following article is from a series of alternate energy articles and tips on the uses of solar powered systems …
As homeowners learn more about the need for conserving energy, many people are opting to install a solar power system in the home. The solar powered home consumes less electricity and is verymost environmentally friendly. However, many people are concerned about the costs involved. In this excerpt, we’ll tell you how installing solar panels in your home can actually be an investment that will save you a lot of money in the long run.
Photovoltaic is defined as electricity from light. This solar power system uses the light of day to power common electrical equipment like household appliances, computers and lighting. Having your own solar photovoltaic (PV) system means that you can generate your own electricity from the free and inexhaustible sun power. A photovoltaic system never needs refueling, emits no pollution and has a normal life expectancy of twenty to twenty-five years with little maintenance needed. A typical PV system on a home roof can prevent over 34 tonnes of greenhouse gas emissions during its lifetime.
The electrical output of a PV cell is dependent upon the intensity of the light to which it is exposed. Therefore, PV cells usually generate more electricity on bright days than when skies are cludy. This doesn’t mean that your solar system will not work when skies are grey. Over the last few years, PV technology has also begun to be introduced into urban areas, incorporated into the roofs and facades of houses, business premises and factories.
There are a few ways to determine what size a solar power system for your home or office should be. You can install as many solar energy modules as your roof can handle. This will increase the solar power generating capacity to completely eliminate your electricity bill. At first, installing more solar energy panels increases the overall value of the system. However, installing more modules beyond a certain limit ceases to be cost effective. It is necessary to do a careful solar site survey using a Solar Pathfinder to work out the net energy output of partially shaded modules and then decide if it is economically beneficial to install modules in those locations.
A solar power system can save you money, but the real benefit is in the reduction of greenhouse gases. Solar power is a rapidly advancing technology and many governments offer incentives to consumers who take measures to make their home environmentally friendly. You can put money back in your pocket while saving the planet for future generations.
