Residential solar electricity is usually seen as an investment. The fact that it is a kind of electricity that helps cut down on electricity bills is a big reason why many people consider it as an investment. People who may be interested in having power in their homes that does not bring about air pollution, has no noise, and does not need maintenance will love electricity produced by solar power.

A solar electrical system is absolutely renewable—meaning that it will never run out. That kind of system is also environment friendly because it aids in the reduction of greenhouse gases and other pollutants. People who are nature lovers and believe in going green will definitely place the solar powered system on the top of their list.

The energy gained from a solar electrical system is more often than not called the photovoltaic energy. A solar electrical system may also be referred to as a photovoltaic system. The system is able to give direct current (DC) electricity through freed up electrons that result from the combination of the photons from sunlight and the silicon atoms from solar panels that are made from semiconductor materials. A standard photovoltaic system may also be composed of an inverter and batteries aside from solar panels.

Some people may wonder why there is the need for an inverter in a solar powered system. Since there are two types of electricity, namely: direct current electricity (DC) and alternate current electricity (AC), there is a need to convert either of the two into the second form.

For example, most of the appliances in the household use AC electricity. Since DC electricity is produced by a solar electrical system, the inverter needs to convert it into AC electricity to give power to the appliances in your house. DC electricity may only be used by small appliances like flashlights, rechargeable lamps, etc. Inverters are of two types: the UPS inverter which relies on batteries, and the Grid-tied inverter which relies on the utility grid to store power.

Many people may also be curious about the total amount of power that a photovoltaic system may be able to provide. The answer, of course, lies on the size of your system. The total amount of electricity a user needs regularly and the total amount of sunlight in his location will also affect the amount of power that a solar powered system will be able to give. It is more feasible to say that the most effective system is one that is used to support around 50% to 75% of the total amount of power your household needs.

If you feel that energy conservation is important and if you want to be able to save more, residential solar electricity may be a good idea. Right now, more and more people feel the need to use a solar powered system in supporting most of their homes’ electricity needs. Who would blame them, when the truth is that gaining electricity from a solar powered system is a money saver.
