The global solar PV operations and maintenance (O&M) market grew significantly in 2025, with assessed capacity reaching a combined 348 GW. This includes 61 GW added within 2025, with the 15 largest O&M providers adding 41 GW to their portfolios.
Their combined capacity reached 200 GW, giving them 57% of the global market share, notes Wood Mackenzie in its Global Solar PV O&M Service Provider Dynamics 2026 report. It tracks more than 130 O&M vendors across the Americas, Asia Pacific excluding China, and Europe, the Middle East and Africa.
Novasource Power Services is the world’s largest solar PV O&M provider, with 38.4 GW under management as of the end of 2025. It was followed by RES Energy Global Services, SOLV Energy, Solarig Energy Services, and Recurrent Energy in that order among the top 5 companies as they pursued cross-regional expansions.
Sterling & Wilson increased its portfolio by 53% to 13.5 GW, moving into sixth place. It managed 12.2 GW in the Asia Pacific excluding China (APeC) region, where it was the largest provider.
BayWa r.e. Services and Origis Energy Services also entered the top 15. Their portfolios increased by 2.6 GW and 1.8 GW, respectively.
Growth varied sharply among individual providers, the report highlights. Engie more than doubled its O&M fleet and moved to 8th place globally, ‘leapfrogging six competitors’. Its Americas portfolio grew 172% during the year.
Among second-tier providers, megaom, the standalone O&M business of FRV, recorded a 243% increase in its portfolio to 3.8 GW, entering the global top 30 for the first time.
“The global O&M market is consolidating quickly around a core group of scaled providers, but the dynamics look very different depending on where you are,” said Khalif Ahmad Zikri, research analyst at Wood Mackenzie.
The regional picture was also uneven. In North America, full-wrap O&M contract costs fell 18% year-on-year (YoY) as competition increased. Meanwhile, O&M volume in the Middle East and Africa nearly doubled in 2025, with new providers entering the market.
