A solar panel is an array of solar cells that use photovoltaic technology to convert direct sunlight into direct current (DC) electricity.
Solar power is very dependable in locations that have bright sunlight 300+ days of the year. In areas with less sunlight, or during periods of cloudiness and storm, solar power is less dependable.
Another use of solar power is to heat water.
When you install solar power panels on your house, you become a part of the solution. Not only do you cut your energy costs but you also supply power back into the grid.
Solar energy is first of all a very useful source of alternative energy, as it can provide electricity during power failures.
Investing in a solar heating system may sound like a big investment, but rest assured you can realize great savings on your energy bills. In fact, you will recoup you investment in approximately 3-4 years making it a free service afterwards.
The main problem with terrestrial solar power is that it only provides power during the daytime.
While the idea of using the power of the sunlight has been around for more than 100 years, it was not until the late 1970s that a genuine effort was made to learn about what is solar power and how it can help reduce the world's reliance on non-renewable energy sources.
The costs for maintaining a solar power system are very low. Some components of the system may last decades without any maintenance at all.
With a small investment, a single solar panel can be built in order to supplement utility company electricity.
