There Are Two Main Types Of Residential Solar Power
There is a difference between solar energy in residential use and that electricity produced for customers or used in businesses. When considering solar energy for home use, the two types are “off grid” or “grid tied”, which is also referred to as net metering.
Off Grid
Off-grid solar energy refers to that power not related to an electric utility or its grid. For this kind of solar energy, power lines do not run to a house but batteries are needed for back-up power storage to cover those hours when there is no sunlight. In the daytime however, the photovoltaic array can store the excess energy in the batteries which is then turned into electricity and given off into the system through the batteries.
In the off grid type of residential solar power systems, there is also need to have a generator which is useful when there is no sunshine as it helps in charging up the batteries rather than use the power from the sun.
Grid Tied
The second kind of solar energy is a net metering system or grid tied, and this type will have power lines connected to a utility company’s electrical system and it does not require batteries for storage. The electric meter will spin backwards in the presence of sunlight, but darkness causes a lack of solar energy which means the meter will spin in a forward direction. This form of residential solar power is administered in a manner quite different from one electric utility company to another with each using its own set of rules and regulations.
There is a lot to recommend using residential solar power in either form since it is a means to get energy that is not only long term, but which is also renewable, and with it, you don’t have to depend any longer on your utility company, and you are also not dependent on foreign governments, and best of all, you don’t need to pay for it. There no doubts that residential solar power is the way to go.
