How Solar Reduces Industrial Energy Costs in India

Industrial electricity tariffs in India have been rising steadily, and demand charges can make up a large share of a factory's power bill. Rooftop solar directly addresses both problems.

A typical 100 kW commercial solar plant in India generates 1.6–1.8 lakh kWh per year. At an average tariff of ₹7/kWh, that translates to ₹14–18 lakhs in annual savings. With a system cost of ₹37–40 lakhs, payback is usually 3–4 years.

Over 25 years, the cumulative savings can exceed ₹3–4 crores. Additional benefits include 40% accelerated depreciation, reduced carbon footprint, and protection against future tariff hikes.

Greentek's C&I projects — including a 3 MW installation for Kajaria Ceramics and a 1.5 MW installation for Nitya Packaging — demonstrate how the right EPC partner can deliver reliable, long-term cost reductions.
