Commercial buildings and technology parks are installing rooftop solar to bring down their electricity expenses and meet a larger share of their power needs on-site. Most such facilities have high daytime electricity usage due to air conditioning, elevators, lighting, server rooms, and other utilities. With on-site solar generation, they can offset a portion of their energy needs.

Gopalan Fortune City Tech Park in Bengaluru has installed a 200 kW rooftop solar system developed by Solar Hitech Solutions to reduce its dependence on grid electricity and lower operational costs. The project was commissioned in July this year.

The rooftop project features 320 solar modules by Saatvik Green Energy and is expected to generate approximately 300,000 units of electricity annually, resulting in estimated annual electricity cost savings of ₹2.2 million (~$23,467). The company used Solex inverters for the project.

Technology parks typically have substantial electricity requirements due to the continuous operation of heating, ventilation, and air conditioning (HVAC) systems, elevators, server rooms, lighting, and other common utilities. Some of these facilities operate around the clock, contributing to sustained electricity demand.

The project also highlights the potential for commercial buildings and technology parks to utilize available rooftop areas for solar installations. Such systems can help businesses reduce operating expenses while making productive use of otherwise underutilized building space.

Last year, Solar Hitech Solutions installed a 400-kW rooftop solar system at AYM Syntex, a textile manufacturer based in Mumbai.

According to Mercom’s Q2 and 1H 2026 India Rooftop Solar Market Report, India added 6.6 GW of rooftop solar capacity in the first half (1H) of calendar year 2026, up 131% from the 2.8 GW installed in 1H 2025.

Residential installations accounted for 84% of total additions. Industrial installations accounted for 10%, followed by commercial installations at 5%, and government installations at 1%.

Mercom India hosts a multi-city Clean Energy Meet series to bring renewable energy developers, vendors, and C&I energy consumers to the same platform, helping them share insights on rooftop solar, open access, and other modes of clean energy procurement. The next event in the series will be held in Pune, Maharashtra, on November 27, 2026.
