Solar is not only for homes. SB TECH, an authorised partner of SolarConnect India, helps shops, offices, institutions, factories and investors in Hooghly, Kolkata and across West Bengal choose the right on-grid, off-grid, semi-hybrid or hybrid system, or plan a large solar power plant.
Pick the system that matches your load, your grid reliability and your backup needs.

| Battery bank | No | Yes (main source at night) | Small, for critical loads | Yes, managed automatically |
| Power during grid outage | No (shuts down for safety) | Yes | Critical loads only | Yes, selected or full loads |
| Net / gross metering | Yes, as per DISCOM | Not applicable | Yes, as per DISCOM | Yes, as per DISCOM |
| Upfront cost (relative) | Lowest | Highest | Moderate | Higher |
| Maintenance | Low | Higher (battery care) | Moderate | Moderate |
| Best for | Bill reduction with stable grid | No-grid or remote sites | Short cuts, essential backup | Bill savings + reliable backup |
Most shops, offices and small factories have a connected load and monthly consumption that a system below 5 kW cannot meaningfully offset. Starting at 5 kW keeps the design, metering and paperwork worthwhile; the right size is fixed only after studying your bills and roof.
If the grid is stable and the goal is a lower bill, on-grid is usually the most economical. If power cuts affect only a few essential loads, semi-hybrid fits. If outages are frequent and costly, choose hybrid. Where there is no grid at all, off-grid is the option. SB TECH helps you compare these for your site.
