Poland solar market 2026: the fastest-growing EU solar market

In 50 words: Poland's solar market reached ~22 GW operating capacity by Q1 2026, growing ~30%/year — the fastest among major EU markets. Residential rooftop drove the early boom; now the net-billing shift, record curtailment, the cable-pooling law and URE auctions are pushing growth toward utility-scale and storage. Government target: ~50 GW by 2030.

Poland went from ~0.5 GW of solar in 2018 to ~22 GW in 2026 — one of the most dramatic growth stories in Europe. The Poland solar market has an unusual shape: residential rooftop dominated early, utility-scale is now catching up fast, and policy is in active flux as the grid strains. This guide covers the Poland solar market in 2026 — the auction and subsidy frameworks, the net-billing shift, curtailment and the cable-pooling fix, leading developers, and the trajectory through 2030.

1. Poland solar market capacity 2026

Poland is the second-largest solar market in Central Europe after Germany, and at ~30% annual growth the fastest-scaling major EU solar market. For broader context, see solar panel price Germany 2026 and EU Solar Rooftops Directive 2026.

2. Residential vs utility-scale split

The Poland solar market split is unusual in EU context:

Through 2022, residential solar in Poland scaled extraordinarily fast — net-metering favoured prosumers and Mój Prąd covered ~50% of small installs. Post-2022 reforms shifted prosumers to net-billing (§3), slowing residential growth but accelerating utility-scale and commercial momentum.

3. Net-billing and the prosumer shift

The pivotal policy change in the Poland solar market was the move from net-metering to net-billing for new prosumers (from April 2022):

• Old model: prosumers banked exported kWh and drew them back ~1:1 (very generous).
• New model (net-billing): exports are sold at a market reference price and imports bought at retail — a much wider spread, so self-consumed energy is worth far more than exported energy.
• Settlement is moving to hourly (RCEm) pricing, exposing prosumers to midday price collapses.

The effect mirrors Western Europe: export value fell, so new residential buyers increasingly add batteries to self-consume — a shift Mój Prąd 6.0 explicitly subsidises (§4).

4. Mój Prąd subsidy program evolution

Mój Prąd (My Energy) is Poland's headline residential solar subsidy:

Mój Prąd 6.0 is the most generous yet — bundling solar PV + battery storage + heat pump under one grant. By rewarding storage, it directly answers the net-billing economics of §3 and keeps residential demand strong.

5. URE auction system for utility-scale

URE (Urząd Regulacji Energetyki) runs annual technology-specific auctions for utility-scale Poland solar:

Winning prices have risen with balance-of-system costs, but utility-scale Polish solar remains cost-competitive against new-build gas. Winners get 15-year fixed-price contracts. Increasingly, large developers bypass auctions entirely via corporate PPAs.

6. Curtailment, negative prices and cable pooling

Poland's breakneck solar growth has outrun its grid, producing two new 2024-2026 phenomena:

• Curtailment: PSE now issues non-market redispatch orders curtailing solar on sunny, low-demand weekends — lost generation that hurts project economics.
• Negative day-ahead prices: midday oversupply periodically pushes wholesale prices below zero.

Two policy responses are reshaping the market:

• Cable pooling (enabled by 2023 law): solar, wind and storage can share a single grid connection point — solar fills the connection capacity that wind leaves idle, dramatically improving connection utilisation.
• Storage: batteries are entering via the capacity market and Mój Prąd, soaking up midday surplus and arbitraging the widening price spread.

7. Top Poland solar developers in 2026

State-owned PGE dominates the largest projects; independents (Polenergia, Onde, foreign IPPs) are growing fast.

8. Grid connection challenges

Grid capacity is the binding constraint on the Poland solar market:

• PSE interconnection queues run 3-5 years for large utility solar.
• Distribution-level constraints bite hardest in western Poland (high solar density).
• Some regions are effectively frozen for new utility solar pending reinforcement.
• New utility projects increasingly must include storage (or use cable pooling) to win a connection.

9. Poland solar vs EU peers

Poland is the EU's fastest-growing major solar market and on track to overtake France. Compare: France solar market 2026, Netherlands solar market 2026, Nordic solar market 2026.

10. Trajectory through 2030

Poland solar capacity projection:

• 2027: ~28 GW
• 2028: ~35 GW
• 2030: ~50 GW (government target)

Drivers: EU Solar Rooftops Directive transposition, Mój Prąd 6.0/7.0, URE auction volumes growing 20-30%/year, the coal phase-out creating offtake demand, and corporate PPAs from re-shoring industry. By 2030 Poland could be the third-largest EU solar market after Germany and Spain.

11. What to watch next in 2026

• Hourly net-billing (RCEm) — how far it pushes prosumers toward batteries.
• Curtailment volumes — whether redispatch and negative prices worsen before storage catches up.
• Cable pooling uptake — how much idle wind-connection capacity solar can fill.
• URE auction sizes — and whether developers keep shifting to corporate PPAs.
• Coal phase-out pace — freeing grid headroom and offtake for solar.

12. Frequently asked questions

How big is Poland's solar market in 2026?

~22 GW operating capacity — the fastest-growing major EU solar market at ~30% annual growth.

What is Mój Prąd?

Poland's residential solar subsidy. Mój Prąd 6.0 (2025-2026) offers up to 28,500 PLN for solar + battery + heat pump packages.

Why did Poland's solar grow so fast?

Generous prosumer net-metering through 2022, Mój Prąd grants, EU funding, and rising power prices that made self-consumption pay.

What changed with net-billing in Poland?

New prosumers (from 2022) sell exports at a market price and buy imports at retail, so self-consumed energy is worth much more than exported — driving battery adoption.

What does utility-scale solar cost in Poland in 2026?

Winning URE auction bids are 280-360 PLN/MWh (~€61-€78); installed cost €700-€900/kWp for typical ground-mount.

Is curtailment a problem for Poland solar?

Increasingly yes — PSE curtails solar on sunny low-demand weekends and midday prices sometimes go negative. Cable pooling and storage are the main fixes.

What's the 2030 target for Poland solar?

~50 GW operating by 2030 — achievable on the current trajectory, potentially making Poland the EU's third-largest solar market.
