TARA POWER TECH offers off grid solar systems of highest quality with MNRE approved components. The term off-grid refers to not being connected to a grid, mainly used in terms of not being connected to the main or national electrical grid. A typical off grid solar system uses batteries to store DC electricity produced by the solar panels. This type of system fulfills the electricity requirements of the building/complex it is installed for through an inverter which converts DC to AC, but it does not feed the grid with its excess power. It rather stores the power in the batteries for power back up. These systems are relatively expensive than the on grid systems but are ideal where power cuts are frequent.
