MJR Pearl, a residential apartment community in Whitefield, Bengaluru, has installed a 150 kW rooftop solar project to reduce electricity costs and support its common-area power requirements.

The project was installed by Beestone Solar India, a Bengaluru-based engineering, procurement, and construction company.

According to the company, it has delivered over 10 MW of fixed solar installations across more than 600 industrial, commercial, and residential projects.

The apartment community uses power backup and other utilities to support resident amenities. The rooftop solar project is expected to help reduce grid electricity consumption and lower residents’ association power bills.

At MJR Pearl, Beestone Solar installed a non-penetration mounting structure, using metal-to-concrete bonding technology. The company said the structure avoids roof penetration and can withstand wind speeds of up to 180 kmph.

The project uses SolarEdge inverter and optimizer technology, enabling real-time performance monitoring of individual solar panels.

According to Beestone Solar, the 150 kW project has helped MJR Pearl reduce electricity bills by 80%.

The apartment association also received a subsidy of ₹2.69 million (~$28,239) under the PM Surya Ghar Muft Bijli Yojana, within 15 days.

The company said the project is expected to generate savings of nearly ₹34.65 million (~$363,741) over its 25-year lifespan, with a return on investment of about four years.

The project is also expected to reduce carbon dioxide emissions annually and save the equivalent of nearly 4,977 trees. Shivraj Vedkikar, Secretary of MJR Pearl Society, said the project execution team worked closely with the maintenance staff, provided regular updates, and completed the project within the committed timeline despite the rainy season.

He said the project team handled the subsidy documentation.

Residential societies have increasingly turned to rooftop solar to reduce common-area electricity expenses, especially for amenities, lighting, lifts, pumps, and backup systems. Subsidies under government programs have improved the economics of eligible projects and housing communities.
