Commercial and industrial (C&I) solar installations offer some of the strongest ROI profiles in the Indian energy market. With rising grid tariffs and improved module efficiency, the business case has never been clearer.
Understanding Your Energy Profile
Before sizing a system, analyze 12 months of electricity bills: peak demand (kW), total consumption (kWh), tariff structure, and time-of-day usage patterns. C&I clients with consistent daytime loads — manufacturing, IT parks, warehouses — are ideal solar candidates.
System Sizing and Yield
A well-designed C&I system targets 60–80% of daytime consumption. Oversizing beyond this leads to export losses unless net metering policies are favorable in your state. Expected specific yield in India ranges from 4.0–5.0 kWh/kWp/day depending on location.
Financial Modeling
For a typical 1 MW rooftop installation in Karnataka: - Capital cost: ₹4.0–4.5 Cr (₹40–45/Wp) - Annual generation: ~14.5 lakh kWh - Annual savings: ₹1.1–1.3 Cr (at ₹7.5/kWh blended tariff) - Simple payback: 3.5–4.5 years - 25-year lifetime savings: ₹25–30 Cr
Performance Monitoring Matters
Installation is only the beginning. Performance ratio (PR) below 75% indicates issues — soiling, shading, inverter faults, or cable losses. Our SolarWatch Pro platform provides daily PR tracking, automated fault alerts, and compliance-ready generation reports.
Incentives and Financing
Explore accelerated depreciation (40% in year one under the Income Tax Act), state-specific subsidies, and green energy certificates. Many NBFCs offer solar-specific financing at 9–11% interest with tenure up to 10 years.
