Traditional energy sources which light up many homes are coupled with alarming levels of global warming, pollution as well as ever increasing costs. This has forced the scientists all over the world to explore the sources of renewable energy which are more economical and non-polluting in nature.

And radiating plenty of energy from sky above is sun in its splendor. Energy that is produced by sun is used to charge batteries. Solar swimming pool heaters, solar water heaters, cookers, streetlights, room heaters are also its many other outcomes. The solar power is transformed into electrical energy by the use of a PV cell, which is a semiconductor device that consists of a big area p-n junction diode. It generates electrical energy in presence of the sunlight.

Installing a photovoltaic solar power generation system in homes is thus a great idea to save the planet. There are a number of benefits of installing it. It adds to the property value and is nearly maintenance free. It is a continuous and reliable source of electricity. This power generation system can reduce CO2 emissions and pollution because it produces electrical power by using sunlight, which is capable of replacing electricity that comes from burning fossil fuels and coal in the electrical plants.

You can save large amounts on your electricity bills once it is installed. Although initial cost of installation may be higher but you can benefit a lot from it in the long run. If the power generated is more than you need, you can sell them through the grid, which is attached with the solar system. You can also get some tax exemptions and rebates with installation of a solar panel in a house if you stay in Australia.

But have you ever thought of what needs to be done for powering the house with this renewable source of energy? It is not that simple as you think. Checking out the solar feasibility report is of utmost importance. Not every roof may have the right orientation to take the full advantage of the power. You need to know the angle of inclination if you want to make the best use of the power.

Non-tracking photovoltaic systems in Northern Hemisphere generally points out toward south though orientations which face in a westerly and easterly direction works too but by sacrificing various efficiency degrees. The solar panels need to be inclined at an angle that's close to areas as latitude as possible for absorbing the utmost amount of energy throughout the year. A different inclination is to be utilized if maximize energy needs to be produced at afternoon or morning or winter or summer. The modules must never be shaded by tall buildings or trees no matter what time of time or day it is. If your house has a southward facing roof and is unshaded, decide on the size of the system that you will need.
