Solar panels for electricity are a good way to reduce your energy consumption. Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity. This electricity can then be used to provide power in your home for electrical loads. The effect of the sun’s light being absorbed and converted to electricity is known as the Photovotaic Effect.
Most homes’ roofs have more than enough room for the number of solar panels to produce enough electricity to supply enough electricity to power the entire house. This is an astounding thought, that we can capture the sun’s power and use it to power the electronics in our homes. This is a very practical way to produce electricity. The upfront cost of the solar panel system is expensive, but the long term savings far outweigh that cost, if you can afford the initial cost.
One place this type system would really be a cost effective way to provide power to a home, would be if you lived in a remote location that was outside the main power grid. This would keep you from paying an electrical company to run power lines and poles out to your remote location.
Solar panels are used a lot by government agencies. Some examples are traffic signals, signs, lights, etc… They can also be used as a source of back up power since the power can be stored. Solar panels are also seen being used in Construction temporary power, RV’s, Emergency & Rescue, and communications.
Some other examples of solar electric systems are solar heating and hot water systems. In this case you would use solar thermal collectors to heat water for domestic hot water, central heating for standard or under floor heating. This is very efficient way of providing hot water to your home, however again the initial cost is expensive, but if you can afford that, the savings are phenomenal.
Solar panels are also being seen used in pool and spa heating systems. These systems tend to be less expensive, and provide a great way to warm up your pool during those cooler months. An average system will heat your pool water 10 degrees.
