Solar Battery Storage in India — 2025 Guide
With frequent power cuts in many parts of India, solar battery storage is increasingly popular. But does it make financial sense? Here's everything you need to know.
Do You Need a Solar Battery?
- Yes, if: You have frequent power cuts (2+ hours/day), you want energy independence, or net metering isn't available in your area
- Maybe not, if: Your grid is reliable and net metering is available — grid is essentially your free battery

Subsidy on Solar Batteries
Currently, standalone battery systems do not qualify for PM Surya Ghar subsidy. However, batteries installed as part of an off-grid solar system may qualify for MNRE off-grid program subsidies in select states.
