Commercial and industrial solar in Punjab
Businesses get no free units and no PM Surya Ghar subsidy. The upside is that solar saves from the very first unit, and most businesses use their power in daylight, when the panels are generating.

What your business pays PSPCL now
Shops, offices, clinics, schools and similar premises are billed under Non-Residential Supply (NRS). Energy is charged from the first unit, with no free allowance:
| Sanctioned load | Units | ₹ per unit | Fixed, ₹ per kW a month |
|---|---|---|---|
| Up to 7 kW | First 500 units | 6.10 | 70 |
| Above 500 units | 7.10 | ||
| 7 to 20 kW | First 500 units | 6.10 | 100 |
| Above 500 units | 7.10 | ||
| 20 to 100 kW | All units | 6.25 | 130 |
| Above 100 kW | All units | 6.45 | 140 |
Effective 01.04.2026 to 31.03.2027. Electricity duty of about 13% is added on top. Always check the figures against your own bill.
Industrial manufacturing units pay a Punjab Government subsidised energy charge of ₹5.835 per kVAh for FY 2026-27, with fixed-charge waivers for Small Power and Medium Supply connections.
Why solar suits business connections
A business connection has no free-units line, so every solar unit you use comes straight off the bill. Most businesses also use their power while the sun is up, and units used on site are worth the full tariff. Tariffs change every year, while a rooftop system fixes the cost of a large share of your power for 25 years.
Solar won’t reduce the fixed charges on your sanctioned load, though. Those stay the same.
Sizing a commercial system
Start from twelve months of bills, because business use changes with the seasons. The system is sized to your daytime consumption and capped at your sanctioned load or contract demand. Larger systems are designed after a site survey, since the roof layout, shading, structure and the cable route to the meter all affect the design.
Payback
Payback depends on the tariff, how much of the generation you use on site, and the system price. For a first estimate, enter a business bill in the calculator and choose your connection type.
Questions we are asked
Do businesses get the PM Surya Ghar subsidy?
No. The subsidy is for homes and housing societies. Commercial and industrial connections pay the full system cost.
How big a system can a business install?
Up to the sanctioned load or contract demand of the connection. If your roof and your use justify more, apply to PSPCL for load enhancement first.
Why does daytime use matter?
Solar generates during the day. A shop, school, clinic or factory that uses most of its power in daylight uses its solar units as they are made, and that is where they are worth the most. Surplus exported to the grid is credited under net metering rules at a lower value.
Are there tax benefits?
Businesses can usually claim depreciation on solar assets, often at an accelerated rate. The current rate and how it applies to you is a question for your chartered accountant.
