Spain added 10.1 GW of solar in 2025 as capture prices weigh on pipeline

Spain's solar sector closed 2025 with 10.1 GW of new installations, according to Spanish PV association UNEF. Ground-mounted projects accounted for 8.97 GW of that figure; self-consumption systems added 1.14 GW. The numbers confirm Spain as one of Europe's fastest-deploying solar zones, but UNEF flags that falling captured prices are compressing project returns and creating headwinds for the next wave of development.

UNEF's statement ties the capture-price problem directly to the absence of co-located storage and insufficient demand-side electrification. Without both, additional solar capacity amplifies the midday oversupply that depresses prices in the Spanish zone. The trade body is explicitly calling for policy and market conditions that incentivise storage alongside generation.

Elsewhere, Poland's active solar pipeline with grid-connection conditions hit 40.6 GW, per an independent Polish research institute. The institute revised its methodology to remove inactive projects, so the headline figure reflects a cleaner, more conservative view of deliverable capacity. Norway crossed 1 GW of cumulative solar installations in the same week, a milestone that Multiconsult analyst Hassan Gholami told pv magazine coincides with a market slowdown requiring large-scale project development and energy-sharing schemes to sustain momentum.
