Off-grid systems involve routing the solar power generated to a battery for storage until needed. In this setup, all the power generated by solar panels is stored locally within customer batteries. Off-grid projects are suitable for customers seeking to reduce electricity bills while also requiring a solution for power failures. This option is advisable for permanent residents in homes who need backup power for essential appliances, including air conditioners, motors, and other heavy equipment. However, it is not recommended for non-resident Indians (NRIs) as the solar power may go unused when customers are away for extended periods.
