Solar Panels for Your Home Info

Solar energy is a form of renewable energy as it utilizes the radiant energy coming from the sun. This is achieved through the conversion of the sun's rays into electrical power by using solar cells.

Solar cells, invented by Charles Fritts in the 1880's, are known as photovoltaics. While they did not create much electricity at the time, the revolution they started has kept going. The solar panels on the Vanguard 1 satellite, is a great example.

The 1973 oil crisis stimulated a significant demand for solar power. Power companies used to charge consumers one hundred dollars for every watt, early on. During the decade of the '80s, it dropped to seven dollars a watt.

While solar energy demand has dropped in the US it is steadly increasing in 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. Specifically, these approaches are active and passive as well as solar photovoltaic processes.

In a passive system the building design will have much to do with the efficiency. The building will be able to contain heat better, allowing the people inside to stay comfortable with help from a controlled ventilation system and day lighting. With just a minimal cost, reductions of up to 80% can be seen in home choose to apply this.

Active solar heating converts sunlight to heat and provides space and water heating. While used in Europe extensively, the right size could help you cover nearly 60% of your hot water heating.

Finally, there is photovoltaic, it converts radiation from the sun into electricity. This happens by installing solar cells, and the more intensity of light, the greater the flow of electricity. They are available in varying sizes, and come installed in devices such as watches and calculators.

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. There are balloons and unmanned aerial vehicles as well. To date, the only success in solar energy has been in passenger boats.

Solar energy is an option to decrease our dependence on oil, as well as preserve the environment. When compared to kerosene and batteries, solar energy is much cheaper to provide power to homes, and we need to convince the government to do more about it. Read about solar panels for your home.
