As solar technology progresses, the more compact a solar power system is becoming, which is increasingly attractive to homeowners who want to reduce their power bills. In addition to being cost effective, the decision to install solar panels into your home is very friendly to the environment. In this excerpt, we’ll explain how solar power works and how you can use it to your advantage.

Photovoltaic means electricity from light. This solar power system uses sunlight 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, does not pollute and can be expected to operate for twenty to twenty-five years with minimal maintenance required. 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. Therefore, PV cells usually generate more electricity on brighter days than when skies are cludy. This doesn’t mean that your solar system will not work when skies are grey. Over the last recent years, PV technology has also started 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 power 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 the point where it can eliminate your electric 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 5 to 10 years — and even faster if you take advantage of manufacturer and government rebates. Solar electricity can raise the value of your home and create a brighter outlook for the future of our planet.
