For years, India’s solar story was led by states like Rajasthan, Gujarat, Karnataka, and Maharashtra. Today, however, a new chapter is unfolding in the east.
Eastern India is rapidly emerging as one of the country’s most promising regions for solar adoption. Rising electricity costs, increasing awareness about energy independence, and easier access to rooftop solar are encouraging more homes, businesses, and institutions to embrace clean energy.
At the forefront of this transition is ONergy Solar, the solar brand of Punam Energy Pvt. Ltd. With more than 15 years of experience in delivering clean energy solutions across West Bengal, Odisha, Assam, and the Northeast, ONergy has established itself as one of Eastern India’s leading solar players. The company has already enabled 300+ households to adopt rooftop solar under the PM Surya Ghar: Muft Bijli Yojana, helping families move towards cleaner, more affordable, and energy-independent living.
Why Eastern India Is Becoming Solar-Ready
Several factors are accelerating solar adoption across the region. Rising electricity costs are making long-term savings more important than ever, while better financing options are making solar increasingly accessible. Businesses are looking for stable and predictable energy costs, and households are seeking greater control over their electricity consumption.
Adding to this momentum is the PM Surya Ghar: Muft Bijli Yojana, a residential rooftop solar initiative that provides financial support to eligible homeowners installing rooftop solar systems. By reducing the upfront investment, the scheme is enabling more families to adopt solar and generate their own power.
West Bengal: Leading the Rooftop Revolution
West Bengal is quickly becoming one of Eastern India’s most exciting solar markets. Cities such as Kolkata, Howrah, Durgapur, and Siliguri are witnessing growing interest in rooftop solar among homeowners and businesses alike.
Despite the common myth that solar doesn’t work well during monsoons, the state receives ample sunlight throughout the year, making solar a practical and cost-effective solution.
Odisha and Assam: Powering the Next Phase of Growth
Odisha is emerging as a key driver of Eastern India’s solar expansion. Its growing industrial and commercial sectors are increasingly exploring solar as a way to reduce operating costs and improve energy reliability.
In Assam and the wider Northeast, solar is doing much more than lowering electricity bills. From schools and healthcare facilities to rural enterprises and community infrastructure, decentralized solar solutions are improving energy access and strengthening resilience.
The Road Ahead
Eastern India’s solar journey is still in its early stages, but the momentum is unmistakable. West Bengal is driving rooftop adoption, Odisha is unlocking its immense solar potential, and Assam and the Northeast are embracing solar to build more resilient communities.
Together, these states are shaping the next phase of India’s clean energy transition, and ONergy Solar is proud to be helping lead the way.
