Many buyers in Bihar install the wrong solar architecture simply because nobody explains how power outages interact with net metering. Use the table below to choose accurately:
| Parameter | On-Grid (Grid-Tied) | Off-Grid (With Battery) | Hybrid (Grid + Battery) |
|---|---|---|---|
| PM Surya Ghar Subsidy | Eligible (up to ₹78,000) | Not eligible | Only grid-tied component if approved; batteries self-funded |
| Outage Backup | No backup during grid failure | Full backup from battery bank | Seamless backup + excess export to grid |
| Net Metering Export | Yes (offsets night bills) | No export | Yes |
| Best Fit in Bihar | Patna, Muzaffarpur, urban towns with stable grid | Remote farms, rural clinics with unreliable supply | Tier-2/3 homes wanting AC backup & bill zeroing |
