The implementation of the Approved List of Models and Manufacturers List II mandate for solar cells is causing a TOPCon module supply squeeze, with developers, engineering, procurement, and construction contractors, and rooftop installers preferring them for their higher efficiency and output.

Large-scale renewable energy deployment in India is entering a phase where project capacity must be matched by transmission infrastructure, capital availability, supply chain readiness, land access, and operational coordination.

Energy storage systems have emerged as a critical pillar of India’s clean energy transition strategy due to their potential to enhance grid reliability, flexibility, and energy security. As solar and wind installations expand rapidly across the country, energy storage is increasingly seen as a key advantage that could pave the way for the seamless integration of clean energy generation, overcoming intermittency and maintaining a stable power ecosystem.

As India’s power demand rises with the expansion of digital infrastructure and commercial and industrial activity, decentralized energy solutions are gaining prominence as businesses seek reliable, cost-effective, and low-carbon electricity sources.

Mercom India will host the sixth edition of its flagship Mercom India Renewables Summit on July 1 and 2, 2026, at the Hyatt Regency in New Delhi. A major event on India’s renewable energy calendar, the Summit will convene industry leaders, policymakers, investors, developers, manufacturers, and technology providers to share insights and discuss the next phase of the country’s clean energy transition.

The global solar industry is undergoing rapid technological transformation. Emerging cell technologies such as perovskites, heterojunction, back-contact architectures, and tandem cells are driving module efficiencies to new heights and reshaping performance benchmarks across the sector.

India is expanding renewable energy deployment as it works toward its target of 500 GW of non-fossil fuel-based energy capacity by 2030. The country installed 15.3 GW of solar capacity in the first quarter of 2026, its highest quarterly total, according to Mercom India’s Q1 2026 India Solar Market Update Report.

As India’s battery energy storage gains wider adoption, the focus has now shifted to project viability and long-term project execution. Battery storage projects are highly sensitive to technical and commercial assumptions, including degradation rates, round-trip efficiency, dispatch strategy, cycling frequency, and revenue-stacking potential, all of which can affect the project’s bankability.

India’s efforts to fast-track its clean energy transition and plan to achieve 500 MW in non-fossil energy capacity by 2030 hinge heavily on the resilience of its solar manufacturing value chain. The government has been emphasizing the development of a fully self-reliant solar manufacturing ecosystem, from polysilicon, ingots, and wafers to cells and modules.
