As people are educated about the need to conserve energy, many of us are choosing to install a solar power system in the home. The solar powered household uses 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 future.

Photovoltaic means electricity from light. This solar power system uses the light of day to power ordinary electrical equipment like household appliances, computers and lights. Having your own solar photovoltaic (PV) system means that you can generate your own electricity from the free and inexhaustible power of the sun. A photovoltaic system never needs refueling, does not pollute and can be expected to operate for twenty to twenty-five years with little maintenance needed. A typical PV system on a home roof could 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. Thus, PV cells usually generate more electricity on bright days than when skies are overcast. This does not 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, offices and factories.

There are a few ways to determine what size a solar powered system for your home or business 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. Initially, 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.

Investing in a solar power system for your home or business is a smart decision, both economically and environmentally. A properly designed and installed solar system can pay for itself in as little as five to ten years — and even faster if you take advantage of manufacturer and government rebates. Solar electricity can raise the value of the home and create a brighter outlook for the future of our planet.
