Case Study: Industrial Solar Power System Installation for Cost Reduction and Efficiency

A mid-sized plastic parts factory in Kanpur used about 500 kW of power each month. They paid ₹18–20 lakhs for electricity before turning to solar. Spectra Solar Power set up a 500 kW rooftop PV system to lower costs and boost reliability. The system had around 1,500 panels, inverters, and mounting. It also included optional battery storage. Costs ranged from ₹2.2–2.5 crore for a grid-tied system to ₹3.2–3.5 crore with batteries. After installation, the results were impressive. The factory saved about 70–80% on electricity bills. This meant saving ₹12–15 lakhs each month, or around ₹1.5 crore annually.
