Romania has emerged as one of Europe’s most dynamic solar markets in 2025, recording a sharp acceleration in photovoltaic deployment over the course of the year. Around 2.5 GW of new solar capacity has been added, representing an increase of nearly 50% compared to last year’s installations. This expansion alone accounts for roughly one third of Romania’s expected total solar capacity by year-end, which is projected to reach about 7.6 GW.
This surge comes at a moment when solar growth across the European Union is losing momentum. New solar installations in the bloc totaled approximately 65.1 GW in 2025, slightly below the 65.6 GW added in the previous year. While several of Europe’s largest solar markets are entering a phase of consolidation, Romania has moved in the opposite direction, emerging as the fastest-growing country by growth rate among Europe’s ten largest solar markets.
Looking ahead, industry forecasts point to continued rapid expansion. Under a mid-range scenario, Romania’s installed solar capacity could triple by 2030, reaching around 24 GW. Such growth would place the country among the six fastest-expanding solar markets within Europe’s top tier. At the EU level, SolarPower Europe estimates that total installed solar capacity across the bloc will approach 718 GW by the end of the decade, a substantial increase but still short of the EU’s stated target of 750 GW.
Analysts attribute Romania’s strong momentum to a balanced growth model combining steady rooftop installations with a rapidly scaling utility-scale solar segment. Key enabling factors include supportive public policies, simplified permitting procedures, faster deployment of battery storage, the gradual development of a power purchase agreement (PPA) market, and the rollout of contracts for difference (CfD) auctions. Together, these elements have allowed Romania to overtake Greece, where residential solar growth has slowed following the phase-out of net metering and delays in the transition to net billing.
