Solar Energy Revealed

Solar energy utilizes the radiant energy that comes from the sun, therefore this is a form of renewable energy. This is achieved through the conversion of the sun’s rays into electrical power by using solar cells.

Charles Fritts invented solar cells, also known as photovoltaics, in the 1880′s. They started a continuing revolution, even though they were unable to convert to a lot of electricity. The solar panels on the Vanguard 1 satellite, is a great example.

A great demand for solar power happened during the 1973 oil crisis. Early on, customers used to pay the power companies a hundred dollars for each watt. It fell to a mere seven dollars per watt during the 1980s.

United States use of solar energy is declining, while its on the rise in countries such as Germany and Japan. From 31.2 megawatts in 1999, up to 318 megawatts by 1999, world wide production growth of 30%. South Korea, Italy, and France are just behind Spain, which is third largest solar power user behind these two nations.

A trio of fundamental approaches exist for maximizing solar energy use. To be precise, these are comprised of passive, active, plus solar-based photovoltaic methods.

In a passive system the building design will have much to do with the efficiency. People inside the building will stay comfortable, due to the building being able to avoid heat loss, as well as the help from the day lighting and controlled ventilation. With just a minimal cost, reductions of up to 80% can be seen in home choose to apply this.

Space and water heating by using converted sunlight is active solar heating. Up to 60% of your water heating can be covered by the correct size, it is done in Europe extensively.

Finally, you have photovoltaic, which makes electricity by converting solar radiation. You install solar cells into the ground, and the higher the light intensity, the higher flow of electricity. The different sizes allow for use in consumer devises.

The power used for some vehicles has been converted to solar. Competitors from all around the world, as well as cars not yet commercially produced, are invited to compete in the World Solar Challenge, an annual event in Australia. Also there are unmanned aerial vehicles as well as balloons. To date, the only success in solar energy has been in passenger boats.

If we want to preserve the environment, as well as reduce our need for oil, solar energy is an option. Our elected officials need to be convinced to do more about solar power, because of it being the cheapest way to provide our homes with electricity.
