Together, these five companies accounted for nearly 30% of the total rooftop solar market. India added 3.2 GW of rooftop solar capacity in 2024, marking an 86% increase from 1.7 GW in 2023, as per Mercom India’s 2024 Q4 &amp; Annual Mercom India Rooftop Solar Market Report.</p>
<p>Multi Infrastructure and Engineering (MIEPL) <a href="https://www.mercomindia.com/multi-infra-wins-cels-auction-to-set-up-200-mw-solar-module-facility" target="_blank" rel="noopener">won</a> Central Electronics’ (CEL) auction for setting up a 200 MW solar module manufacturing facility in Ghaziabad, Uttar Pradesh. CEL floated the tender in April this year. MEIPL must implement the project on a revenue-sharing model under the Make in India initiative. The company said the proposed facility is expected to bolster the production of solar modules within the country, reduce import dependency, and contribute to India’s clean energy transition. MEIPL is an engineering, procurement, and construction company working on railway general electrification, gas pipelines, water pipelines, and electrical substations and lines.</p>
<p>The increasing integration of renewable energy <a href="https://www.mercomindia.com/operators-struggle-to-balance-solar-with-thermal-power-as-grid-woes-rise" target="_blank" rel="noopener">continues</a> to stress India’s electricity grid, causing repeated frequency fluctuations. The grid has seen persistent high frequency above the ceiling on 39 days in the third and fourth quarters of the financial year 2024-25, triggering concerns among grid operators and regulators. The frequency was above the Indian Electricity Grid Code band of 49.90-50.05 Hz for over 20% of the time on these days during the two quarters. The high-frequency periods were attributed to increased levels of solar power injection and the limited flexibility to reduce thermal generation to accommodate renewable energy production. On certain days, the down reserves during solar hours were completely depleted.</p>
<p>Hydrogen fuel cell solutions provider Plug Power <a href="https://www.mercomindia.com/plug-power-q1-revenue-up-11-yoy" target="_blank" rel="noopener">reported</a> a revenue of $133.67 million in the first quarter of 2025, an 11% year-over-year increase compared to $120.26 million. This growth was driven by rising demand for electrolyzers, consistent material handling activity, and continued deployment within its cryogenic platform. The revenue exceeded analysts’ expectations by $1.88 million. The company’s net loss fell to $196.65 million from a net loss of $295.77 million in the corresponding period last year. Its loss per share came in at $0.21, missing the analysts’ estimate by $0.02.</p>
