| In an Off Grid (or Stand Alone) Solar Power System, the house has no connection or disconnected from the utility grid and often relies on a bank of batteries to store power for use at night and during periods of limited sun.Although the up-front cost of these systems can be higher, Stand Alone Solar Power Systems are a very cost effective solution for rural households or businesses faced with a large connection cost to the main electricity grid. They also allow a consumer or business to remove themselves from the future risk of rising electricity prices.
An inactive connection to the grid or a generator is usually provided as an additional back up for these systems. Generator becomes the only backup if the house has no connection to grid. |
