As commercial and industrial companies explore clean energy options to offset rising energy costs and meet their sustainability commitments, on-site rooftop solar solutions have emerged as a viable solution.

For large-scale manufacturers, electricity is a critical input that affects production costs, particularly at facilities where refrigeration, bottling lines, packaging equipment, and round-the-clock operations demand substantial power.

Understanding how an insufficient power supply can hamper production lines, companies are leveraging solar rooftop solutions to not just slash grid power costs but meet fluctuating power requirements.

In April 2026, Haryana-based Varun Beverages (VBL) commissioned a 5.5 MW rooftop solar power system at its Supa manufacturing facility in Parner, Maharashtra and is now looking to reduce its electricity expenditure by an estimated ₹60 million (~$629,000) annually.

The project is expected to generate approximately 7.5 GW electricity annually and will meet around 20% of the facility’s total electricity requirements. The company has estimated monthly savings of up to ₹5.5 million (~$58,000), with every unit of solar electricity offsetting grid power priced at approximately ₹8.30 (~$0.087)/kWh.

The Supa facility consumes approximately 37.7 million units of electricity annually and operates with a contracted demand of 9,990 kVA. Electricity consumption at the facility varies significantly throughout the year, ranging from about 1.7 million units during lean production months to nearly 4 million units during peak production months.

Developed by Delhi-based Vibgyor Energy, the solar project was designed based on an analysis of 12 months of consumption data to accurately match the facility’s seasonal load profile and avoid over- or undersizing.

The rooftop installation consists of 9,322 RenewSys solar modules rated at 590 W each and 32 Sungrow SG125CX-P2 string inverters.

Ishaan Gadhoke, Executive Director at Vibgyor Energy, said that the use of string inverter architecture enables granular maximum power point tracking and string-level monitoring across multiple rooftop sections, improving energy generation and fault detection capabilities.

The project spans multiple rooftops across the main facility and other buildings, each with different structural characteristics, orientations, and rooftop obstacles.
