Solar Power Generator - The sun is Reliable
Solar power is everywhere. The sun is giving off an enormous amount of energy
and the amount that hits the earth every minute is enough to supply the entire
energy needs of the planet for a year! Unfortunately we don’t harness that
energy as much as we could, but with a solar power generator anyone can get
electricity from the sun.
Solar power provides free, non-polluting energy, so the sooner we take advantage
of this energy source the better off for the planet and future generations.
A solar power generator consists of solar panels which are constructed of arrays
of solar cells – also called photovoltaic's. Each individual cell produces just a
small amount of electricity, but they can be joined together in arrays to
provide energy levels suitable for powering most of the appliances in a home.
Solar cells only produce electricity during daylight hours, so one of the
biggest problems of solar power generators is how to store the power for use
during the night. One solution is to use batteries.
Rechargeable batteries have a limited life-span. Batteries that are recharged
daily may only last 2 or 3 years before needing to be replaced. And they are
expensive.
A better alternative is to hook up the solar power generator to the power
utility grid. If excess power is produced during daylight hours it is fed back
into the grid for a credit against your power bill. This system is very easy to
maintain and frees you from the need of replacing batteries.
Solar power is not just for electricity. It can also be used to provide hot
water. Pipes circulate water through solar panels and the hot water is stored in
tanks. A family which is careful about using too much hot water during night
time hours can get all their hot water from solar power.
It is just a matter of time before we switch from being dependent on fossil
fuels to using more environmentally friendly power sources. Solar power
generators will play a big part in providing power for a cleaner, brighter
future.
