Solar power systems exist in two kinds. The first kind is 'Solar thermal collector' panels, which focus solar energy into a liquid medium, usually water, heating the liquid that is then utilized as and where it is required. The other kind is the photovoltaic module. They convert the sun’s energy into electricity, which can then be distributed immediately or stored within a battery to be used later.

Photovoltaic (PV) and solar thermal panels are both made of silicon. They act as semiconductors. When sunlight hits the solar power panels, some of the energy is absorbed within the semiconductor material. That energy knocks electrons within the silicon loose, allowing them to flow freely.

Once the electric fields within the panels are freed by light energy, they force electrons to flow in one specific direction. This flow of electrons is also called a current. By simply positioning metal contacts on the top and bottom of the solar panels, the current can be drawn off as electricity to be used externally.

Solar panels have built-in electric fields that, when combined with the current described above, will give us what we call a wattage. We use this to describe the power of individual panel.

There are many very good reasons for installing home solar power systems. Top of the list is the huge savings you will make on your utility bills. Many people feel good that they are cutting down on their carbon footprint. Solar panels give out next to no carbon dioxide. Thereby, they reduce our carbon dioxide emissions by approximately 1.two million tonnes per annum.

Solar panels are most frequently fitted to the roof or along an external wall of the home. Be sure to check with the local council before doing this. The local authorities in most countries agree that it is acceptable to install solar roof panels. However, certain locations do require detailed listed criteria.

Solar power is one of the most bountiful of the possible energy supplies that we have here on Planet Earth. As the technology behind solar panels improves in terms of their efficiency, so the cost of installing them is falling. When added to a range of governmental subsidies, tax credits, rebates and grants, the widespread installation of solar panels onto the average householder's roof will become more and more realistic. As the prices are falling further thanks to the local competition in the marketplace, so, it would seem that the future of solar panels is very bright indeed. Learn how to build a solar panel today!

Energy direct from the Sun

A Solar power system uses the suns light and transforms it into a source of energy.

In remote areas solar energy has become a reliable counterpart to conventional power sources. It has even been utilised out in space. Solar power systems are used widely in lighting, homes, cooking and architectural programs. Because of the dramatic rise in the cost of fossil fuels, solar energy has become more popular. The main function of solar panels is to collect and focus the sun’s power.

Solar enegy obtained by the solar panels is then changed into useable power. This can be attained by the process of thermal application. It involves using the energy from the sun to directly heat air or liquids. The process of photoelectric application involves the use of photovoltaic cells to change the energy into electricity.

As it is poses no harm to the environment, solar power is really a true green enrgy. However, other threats to the environment may affect the ability to use solar power system in the future. Global dimming is the result of pollution. It diminishes the quantity of sunlight reaching the surface of the earth. A recent concern is global dimming, an effect of pollution that is allowing less sunlight to reach the Earth’s surface. The problem of global dimming is caused largely by global warming and pollution particles.

The Solar Electric Power Association is a group formed by electric utility companies and the solar power industry. They fused to look for the solutions to deilver our energy requirements. SEPA is a network of more than one hundred companies. There are fifty utility companies, twenty five solar companies and the others are made up of a variety of business types. They share experiences, knowledge, and information about solar programs, They also discuss policies and technology relating to their field.

Solar energy-is it right for you? There are clear benefits to using a safe and abundant solar energy over depleting fossil fuels. Once solar energy is installed it is free. It can be used in areas where electricity can’t be set up easily. The sun is not a resource that is going to be depleted any time soon. A disadvantage is that it will not function at night. The cost of creating solar power stations to store such energy is very expensive.

Lack of natural available sunlight is a problem for some parts of the world where solar energy is not an option.
