EU installs 33.8 GW of solar in the first half of 2026

Никита ЛуценкоОснователь и CEO, SOLTECH

The EU added at least 33.8 GW of solar in H1 2026, up 1.9% year on year, and SolarPower Europe now expects 68.1 GW for the full year - 2.1% below the 2025 record.

EU solar installations reached at least 33.8 GW in the first half of 2026, up 1.9% on the 33.2 GW added in H1 2025. SolarPower Europe published the figure on 8 September 2026 in its EU Solar Market Update 2026: Mid-Year Analysis, and raised its full-year central forecast to 68.1 GW - 6.6 GW higher than its December 2025 estimate and 2.1% below the 2025 record.

EU solar installations in 2026: the numbers

Which markets grew and which shrank

Germany and Spain, the two largest EU markets, held their installation levels. France, Italy, Poland, Romania and Greece each recorded slight year-on-year growth. Finland and Latvia expanded quickly, driven by a handful of large projects being commissioned rather than by broad-based demand.

Four markets went the other way. The Netherlands, Czechia, Belgium and Hungary all came in below their 2025 levels. Within rooftop, the split matters: residential demand weakened in several countries while the commercial and industrial segment held up better. That is the same pattern visible in module procurement data, where European module and inverter prices fell through August 2026.

Solar as an energy-security asset, not just a decarbonisation one

The most striking number in the update is not a capacity figure. SolarPower Europe estimates EU solar generation avoided roughly EUR 30 billion in gas import costs for power generation in the six months from 1 March 2026, following the escalation of conflict in the Middle East - more than EUR 1 billion a week.

Solar met over 20% of EU electricity demand in May, June and July, peaking at a record 25% in June, when it was the Union's largest source of generation. High output also covered cooling demand during heatwaves at a time when high river temperatures and low water levels constrained nuclear and hydro availability.

The bottleneck is the grid, not the panel

The report is blunt about what limits the next stage. Curtailment of renewables is rising, solar capture prices are falling, negative price episodes are more frequent, and evening price spikes are growing. Grids, storage and other flexibility are not keeping pace with generation. Without faster deployment of those, the report says, Europe risks wasting cheap midday solar and then paying for expensive fossil generation after sunset.

Reduced policy support in several member states, regulatory uncertainty and grid connection queues remain the structural risks to the 68.1 GW central case.

Позиция SOLTECH

Europe has arrived at the problem the Gulf has not yet had to face, and the order of events is instructive. Europe built generation first and flexibility second, and is now paying for that sequence in curtailment and negative prices. The GCC is building both at once - DEWA's phase seven pairs 2,000 MW of solar with 8,400 MWh of storage, and Abu Dhabi's round-the-clock project pairs 5.2 GW with 19 GWh. That is not Gulf foresight so much as good timing: batteries got cheap before the Gulf's build-out peaked.

For a villa owner in Dubai this report changes nothing operationally. Your rooftop system is sized against a DEWA tariff, not against European capture prices, and net metering under Shams Dubai does not expose you to midday price collapse. What it does affect is procurement: a European market running flat rather than growing keeps Chinese manufacturers competing for orders in our region, which is one of the reasons module quotes into the UAE have stayed soft. We would not build a purchase decision on that assumption lasting, but it is real today.

For a factory or warehouse owner, the more useful signal is the residential-versus-C&I split. Across Europe, residential solar weakened while commercial and industrial held up. The reason is that C&I economics rest on displacing a daytime tariff during working hours, which is the same logic that makes an industrial roof in Dubai or Sharjah work. That logic is durable; subsidy-driven residential demand is not.

For an investor, one caution. The EUR 30 billion avoided-gas-cost figure is an association's estimate of a counterfactual, not an audited number, and it depends on assumed gas prices. It is directionally credible and we would use it in a narrative slide, not in a model. The number we would actually build on is the 25% June share - that is measured generation, and it is the one that tells you how quickly a grid can shift.
