Solar Panels for EV Charging in Poland: Mój Prąd, Net Billing, and the Real Numbers
Poland is one of the fastest-growing solar markets in the EU. Rising electricity prices, generous subsidies, and a coal-heavy grid make the case for solar + EV unusually strong.
Poland's Solar Surge — and Why EVs Change the Maths
Poland installed more residential solar capacity in 2023 than almost any other EU member state relative to its existing base. The Mój Prąd subsidy programme, rising electricity prices, and a grid carbon intensity among the highest in Europe have driven adoption — and the arrival of affordable EVs is now making the case even stronger.
This guide uses PVGIS irradiance data for Polish cities, current G11 household tariffs, and real installation costs to give you a data-based answer.
Polish Electricity Prices in 2026
After the government price freeze ended, household electricity in Poland sits at approximately 0.80–0.90 PLN/kWh (€0.19–0.22/kWh) under the standard G11 tariff. That is still below the German or Italian average, but it has risen roughly 40% since 2021 and is expected to keep climbing as coal plant retirements reduce cheap baseload supply.
Every kWh your solar panels produce is worth that 0.80–0.90 PLN in avoided grid cost — and that value increases every year.
Solar Irradiance Across Poland
Despite its latitude, Poland has usable solar resource throughout the country — strongest in the south and southwest.
| City | Peak sun hours/day | Annual yield per 400W panel |
|---|---|---|
| Wrocław | 3.9 h/day | 454 kWh |
| Kraków | 3.8 h/day | 442 kWh |
| Warsaw | 3.7 h/day | 430 kWh |
| Poznań | 3.7 h/day | 430 kWh |
| Gdańsk | 3.3 h/day | 384 kWh |
A system to cover a VW ID.4 doing 18,000 km/year needs roughly 8–10 panels in Warsaw, or 7–8 in sunnier Wrocław.
CO₂ Impact: One of the Biggest in Europe
Poland's grid carbon intensity is approximately 650 g CO₂/kWh — among the highest in the EU due to ongoing coal dependence. Solar panels in Poland therefore avoid more CO₂ per kWh than almost anywhere else on the continent.
For an EV doing 18,000 km/year charged entirely from solar, annual CO₂ savings reach approximately 2.5 tonnes — the equivalent of taking a petrol car off the road entirely.
Mój Prąd and the Termomodernizacyjna Relief
Mój Prąd (My Power), run by the National Fund for Environmental Protection, offers direct grants of up to 6,000–7,000 PLN (≈€1,400–1,650) for PV systems paired with a heat pump or home energy management system. Over a million Polish households have benefited from previous editions.
In parallel, the thermal modernisation tax relief (ulga termomodernizacyjna) allows a deduction of up to 53,000 PLN spread across up to six tax years. Together, these two programmes can cover 25–35% of total installation cost.
Net Billing Since 2022: Self-Consumption Is King
Poland replaced 1:1 net metering with net billing in April 2022. Under the current system, electricity you export to the grid is credited at the wholesale market price — roughly 0.35–0.45 PLN/kWh — rather than the retail rate you pay to import.
The practical consequence: scheduling your EV to charge during peak solar production hours (11:00–15:00) is worth significantly more than exporting that same energy. Smart chargers and home energy management systems pay for themselves quickly under net billing.
A Warsaw Example
EV: Volkswagen ID.4 Pro (21 kWh/100 km) | Distance: 18,000 km/year | Tariff: 0.85 PLN/kWh (€0.20/kWh)
| Annual EV consumption | 3,780 kWh |
| Panels needed | 9 × 400W |
| Annual solar savings | ~3,240 kWh × €0.20 = €648/year |
| System cost (installed) | ~€7,000–8,000 |
| After Mój Prąd grant | ~€5,600–6,600 |
| Payback period | ~9–10 years |
| 25-year profit | ~€8,500 |
The longer payback versus southern Europe reflects Poland's lower retail tariff. As electricity prices continue to rise — which they have every year since 2021 — the payback shortens retroactively.
Is Solar + EV Worth It in Poland?
Yes, particularly if you can charge your EV during daylight hours and access Mój Prąd or the termomodernizacyjna deduction. Poland's high CO₂ intensity, rising electricity prices, and relatively affordable installation costs (lower labour than Western Europe) make it one of the stronger cases for residential solar in Central Europe.
