An off-grid solar system in India is generally more prevalent in the Indian market. An off-grid solar system typically consists of solar panels, inverter, mounting structure, power backup, grid box and balance of systems. An off-grid solar system works independently of the grid.

People generally prefer off-grid solar system in India because of non-clarity around net metering norms in different states. Also, approval of government subsidies in the residential rooftop segment is based on various clearances and proper documentation. All these have proven to be major hurdles for the on-grid market in India.
