Homeowners save on solar. Businesses make money on it. With commercial tariffs at ₹8–11/unit and tax benefits homeowners don't get, a rooftop plant is one of the highest-return capital decisions a Rajasthan business can make in 2026. Here's the math.
What C&I solar costs in 2026
| System | Turnkey Price | Yearly Saving* | Payback |
|---|---|---|---|
| 10 kW | ₹3.5 – ₹4.5 lakh | ₹1.2 – ₹1.5 lakh | ~3 years |
| 25 kW | ₹8.8 – ₹11.3 lakh | ₹3.0 – ₹3.7 lakh | ~3 years |
| 50 kW | ₹17.5 – ₹22.5 lakh | ₹6.0 – ₹7.5 lakh | ~3 years |
| 100 kW | ₹35 – ₹45 lakh | ₹12 – ₹15 lakh | ~3 years |
*At ≈ ₹9/unit commercial tariff. Turnkey rate ≈ ₹35,000–45,000 per kW for C&I rooftops. GST extra.
The tax benefits homeowners can't claim
- 40% Accelerated Depreciation: A business can depreciate 40% of the solar asset in year one, slashing taxable profit — for a 25%+ tax bracket, that's effectively ~10% of system cost back in year one.
- GST Input Credit: GST-registered entities claim back the GST paid on the system.
- Net metering for businesses: Rajasthan DISCOMs permit net metering for commercial rooftops within prescribed capacity limits — surplus weekend power offsets weekday bills.
OPEX model: solar with zero investment
No capital budget? Under a PPA/OPEX model, an investor builds the plant on your roof and you simply buy the power at ₹3.5–4.5/unit — locked for 15–25 years against a grid tariff that rises every year. You save 40–60% from day one with zero risk on your books.
Why daytime load matters
Solar pays back fastest for businesses that consume power when the sun shines — 9 AM to 5 PM. A showroom that runs ACs all day captures every unit directly; a night-shift factory would lean more on net metering or storage. Our engineers model your actual load curve before quoting.
