<p>Together, these companies accounted for approximately 86% of O&amp;M capacity contracted in 2025, reflecting high market consolidation among leading players and highlighting the growing preference for experienced service providers capable of managing large, complex renewable energy projects.</p>

<p>Inox Green led the market in 2025, accounting for about 27% of the total contracted solar O&amp;M capacity. The company’s growth was supported by its ability to secure long-term service agreements for utility-scale projects and maintain scale-driven operational efficiency.</p>
<p>Mitarsh Energy followed closely, accounting for roughly 25% of O&amp;M capacity additions in 2025. The company expanded its operations in the solar and hybrid power project segment, building a diversified O&amp;M portfolio aligned with growth in utility-scale installations.</p>
<p>Jakson Green ranked third, adding approximately 14% of the contracted capacity in 2025. Its integrated engineering, procurement, and construction (EPC) and O&amp;M capabilities supported contract wins by offering end-to-end solutions, particularly for large-scale projects transitioning into long-term operations.</p>
<p>Inspire Clean Energy secured the fourth position with over 12% share. The company focuses on solar asset management and performance optimization, with services spanning utility-scale and distributed projects. The growth reflects rising demand from independent power producers and rooftop asset owners seeking specialized O&amp;M solutions to enhance efficiency and extend asset lifecycles.</p>
<p>Sterling and Wilson came in fifth, accounting for more than 8% of the market share in 2025. Leveraging its global EPC experience and large installed project base, the company continued to expand its portfolio by converting executed projects into long-term O&amp;M service contracts across domestic markets.</p>
<p>India’s solar O&amp;M services market continued to expand in 2025, supported by a rapidly growing installed base of utility-scale and open access projects. As more projects transition from commissioning to the operational phase, the focus has shifted toward ensuring high project performance, minimizing downtime, and improving generation efficiency.</p>
<p>This trend has led to greater reliance on specialized O&amp;M providers, with developers and asset owners increasingly outsourcing operations to optimize long-term asset performance.</p>
<p>In 2025, several entities floated tenders for comprehensive O&amp;M services totaling over 1.6 GW across ground-mounted and rooftop solar projects, according to Mercom’s <a href="https://www.mercomindia.com/product/india-solar-tender-tracker" target="_blank" rel="noopener">India Solar Tender Tracker</a>.</p>
<p>In May 2025, Inox Green signed agreements to provide O&amp;M services for 285 MWdc of solar projects. In September 2025, the company received another order covering 96.6 MWdc of projects in Maharashtra and 92.5 MWdc in Gujarat and Madhya Pradesh.</p>
<p>Mitarsh Energy signed O&amp;M agreements for 375 MWdc with <a href="https://www.herofutureenergies.com/" target="_blank" rel="noopener">Hero Future Energies</a> in May 2025 and 190 MWdc with Reliance New Energy, a wholly owned subsidiary of <a href="https://www.ril.com/" target="_blank" rel="noopener">Reliance Industries</a>, in June 2025.</p>
<p>Jakson Green secured 1 GWdc of O&amp;M projects across Rajasthan, Chhattisgarh, and Tamil Nadu during the year, reflecting strong execution capability and sustained demand for third-party O&amp;M services.</p>
<p>The market is also witnessing a gradual shift toward data-driven maintenance practices, including remote monitoring, predictive analytics, and performance optimization tools. At the same time, rising competition is exerting pressure on service pricing, while scale, execution capability, and long-term contract visibility are emerging as key differentiators.</p>
<p>Overall, the expansion of O&amp;M portfolios is closely linked to the rapid pace of solar installations in India. As more capacity comes online, demand for structured, technology-driven maintenance is expected to increase, driving greater outsourcing and longer-term service agreements. Installation growth will remain a key driver for the O&amp;M services market.</p>
