The global solar PV O&M market reached 348 GW in 2025, with the 15 largest providers controlling 57% of managed capacity as consolidation accelerated. NovaSource remained the global leader, while rapid portfolio growth reshaped provider rankings and regional markets.
The global solar PV operations and maintenance (O&M) market reached 348 GW at the end of 2025, after adding 61 GW during the year. The expansion came amid accelerating industry consolidation, with the 15 largest providers managing 200 GW, or 57% of the capacity analyzed.
The figures come from Wood Mackenzie’s “Global Solar PV O&M Service Provider Dynamics 2026” report, which examines portfolio sizes, cost trends and service strategies among more than 130 active providers across the Americas, Asia-Pacific excluding China, and Europe, the Middle East and Africa.
Consolidation accelerated in 2025, with the 15 largest providers adding a combined 41 GW to their portfolios to reach 200 GW of managed capacity. NovaSource Power Services retained its position as the world’s largest solar PV O&M provider, with 38.4 GW under management at the end of the year.
RES Energy Global Services, Solv Energy, Solarig Energy Services and Recurrent Energy retained their positions among the five largest providers globally. Several are pursuing cross-regional expansion strategies as scale becomes an increasingly important competitive factor.
