Energy from the Sun

The Sun is amazingly powerful, and the solar power is the basis for all life on earth. The production of the solar energy does not produce air as well as noise pollution and is considered the most cleaner and greener source of energy. Moreover, solar power is renewable, so it makes sense to explore advances in solar energy technology. There are two key ways to use the Sun's energy.

- Generating electricity using solar panels with photovoltaic effect
- Using heated water for home heating system or generating power with the help of it.

Energy from the Sun
Commonly, solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well.

Solar panels have no moving parts. Mount them out in the sun, hook up the wires, and collect power, without adding fuel or replacing worn-out parts. Nobody knows for sure how long a solar panel will last. Many of the very first photovoltaic panels are still producing power today.

If you are going to buy solar panels, compare them by dollars per watt. Used solar panels are a bargain in every way. Nowadays, Nanosolar Company claims to be the first solar panel manufacturer to be able to profitably sell solar panels for less than $1 a watt.

The sun is there everyday for all of us to enjoy and benefit from. With rising energy prices and growing environmental concerns it's time for us to realize that we all own the sun and it's up to us to use its power.
