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.

Frequently asked questions

1. Poland solar market capacity 2026

| Year | Operating solar capacity (GW) | Annual additions (GW) | |---|---|---| | 2018 | 0.5 | 0.1 | | 2020 | 4.0 | 2.2 | | 2022 | 12.0 | 4.5 | | 2024 | 17.5 | 3.0 | | 2025 | 20.0 | 2.5 | | 2026 (Q1) | 22.0 | ~3.0 estimated full-year |

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:

| Segment | 2026 share of operating capacity | Growth driver | |---|---|---| | Residential rooftop (≤50 kWp) | ~55% | Mój Prąd subsidy + net-metering legacy | | Commercial rooftop (50-1,000 kWp) | ~15% | Self-consumption + corporate PPA | | Utility-scale (>1 MWp) | ~30% | URE auctions + corporate PPA |

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:

| Edition | Years | Per-installation subsidy | Total budget | |---|---|---|---| | Mój Prąd 1.0 | 2019-2020 | 5,000 PLN | 1.0 billion PLN | | Mój Prąd 2.0 | 2020-2021 | 5,000 PLN | 0.5 billion PLN | | Mój Prąd 3.0 | 2021-2022 | 3,000 PLN | 0.5 billion PLN | | Mój Prąd 4.0 | 2022-2023 | 4,000-7,000 PLN | 1.0 billion PLN | | Mój Prąd 5.0 | 2023-2024 | 4,000-22,500 PLN (with battery) | 1.5 billion PLN | | Mój Prąd 6.0 | 2025-2026 | Up to 28,500 PLN with battery + heat pump | 2.0 billion PLN |

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:

| Year | Solar auction capacity awarded | Average winning bid (PLN/MWh) | |---|---|---| | 2020 | 800 MW | 220-240 (~€48-€52) | | 2022 | 1,400 MW | 240-280 (~€52-€61) | | 2024 | 1,800 MW | 260-310 (~€57-€68) | | 2025 | 2,200 MW | 280-340 (~€61-€74) | | 2026 (Q1) | ~600 MW first round | 300-360 (~€65-€78) |

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

| Developer | Poland solar footprint 2026 | |---|---| | PGE Energia Odnawialna | ~3 GW operating + 4 GW pipeline (state-owned, dominant) | | RWE Renewables Poland | ~1.5 GW pipeline | | Polenergia / Enerpark | ~1 GW operating + pipeline | | Onde Group | EPC + smaller developer | | BayWa r.e. Poland | ~0.5 GW pipeline | | EDF Renewables Polska | ~0.4 GW | | Greenvolt Poland | ~0.4 GW | | Ørsted Poland | Smaller solar alongside major offshore wind | | Many local + regional EPCs | Long tail |

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

| Country | Operating solar 2026 (approx.) | 2026 growth | Primary support | |---|---|---|---| | Germany | ~95 GW | ~10-15% | EEG feed-in / market premium | | Italy | ~38 GW | ~8% | FER auctions + detrazione | | Spain | ~35 GW | ~12% | Autoconsumo | | Netherlands | ~28 GW | ~10% | Net-metering (phasing down) | | France | ~24 GW | ~25% | CRE tenders | | Poland | ~22 GW | ~30% (fastest) | Mój Prąd + URE auctions |

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.
