Solar Panel Regulations and Prosumer Policy in Poland
Poland has experienced one of the fastest solar energy adoption rates in Europe over the past five years. The combination of falling photovoltaic panel costs, government subsidy programmes, and a net-billing compensation model has transformed the residential energy landscape.
The prosumer model
A prosumer in the Polish context is a household or small business that both generates and consumes electricity from a renewable source, typically rooftop solar panels. The concept was formalised in the 2015 Renewable Energy Sources Act (Ustawa o odnawialnych źródłach energii) and has since undergone several revisions.
Under the current net-billing system, which replaced net-metering in July 2022, prosumers sell surplus energy to the grid at a market-referenced price and purchase energy back at the retail tariff. The difference between the two rates determines the economic return on the installation.
As of early 2026, over 1.5 million prosumer installations are registered with Polish distribution system operators. The average system size has grown from 5 kWp in 2020 to approximately 8 kWp, reflecting both panel cost reductions and increased household energy demand.
Mój Prąd subsidy programme
The Mój Prąd (My Electricity) programme, administered by the National Fund for Environmental Protection and Water Management (NFOŚiGW), provides direct grants for residential photovoltaic installations. The sixth edition of the programme, launched in March 2026, offers grants of up to PLN 7,000 for PV systems and an additional PLN 5,000 for energy storage installations.
- Grant amount: up to PLN 7,000 for PV, PLN 5,000 for storage
- Eligible system size: 2–10 kWp for residential prosumers
- Requirement: net-billing agreement with local DSO
- Budget allocation: PLN 900 million for 2026 edition
- Application: online via mojelektrownia.gov.pl portal
Installation permits and procedures
Residential PV installations up to 50 kWp do not require a building permit in Poland. However, installers must notify the local distribution system operator (DSO) and obtain grid connection approval before commissioning the system. The process typically takes 30 to 90 days depending on the region and local grid capacity.
For installations exceeding 50 kWp, a full building permit and environmental impact assessment may be required. Commercial rooftop systems and ground-mounted arrays fall into this category and involve additional consultation with local planning authorities.
Grid connection and technical standards
All prosumer installations must comply with the PN-EN 50549 standard for generators connected to low-voltage distribution networks. Key technical requirements include automatic disconnection in the event of grid failure (anti-islanding protection), power quality compliance, and remote disconnection capability.
The grid connection process involves submitting a connection application to the local DSO, receiving technical conditions, installing the system according to those conditions, and passing a compliance inspection before the meter is reconfigured for bidirectional measurement.
Economic outlook
The average payback period for a residential PV system in Poland currently ranges from 6 to 8 years, depending on local irradiation levels, energy consumption patterns, and the proportion of self-consumption versus grid export. Southern voivodeships (Małopolska, Podkarpackie) typically achieve shorter payback periods due to higher solar irradiation.
Looking ahead, the combination of rising electricity prices, further reductions in panel costs, and the integration of battery storage is expected to improve the economics of residential solar further. The Polish government has set a target of 30 GW installed solar capacity by 2030, up from approximately 17 GW at the end of 2025.
