Solar tariffs and regulations in Poland
Poland is the largest European tariff library in solarVis after Türkiye, with 56 Tauron and PGE tariffs. Two prosumer regimes run side by side, and the connection date decides which one applies.
Every market, every tariff, built in
Net metering, net billing, credit carry-over, feed-in tariffs and hourly or monthly netting all live in the tariff configurator, alongside time-of-use, tiered and demand charge structures. Tune currency, seasons, export rates and VAT, or build a brand-new tariff structure when a market changes the rules. Pre-built for the US, UK, Germany, Türkiye, South Africa, Italy, Spain, France, Poland and the Netherlands.

Two regimes, split by the connection date
Plants connected before 1 April 2022 keep quantity-based net metering, the opusty system, with its 0.8 and 0.7 ratios for 15 years. Everything connected after that date is on net billing. The same rooftop is a different investment depending on which side of the line it falls.
Net billing and the prosumer deposit
Exports are valued at the monthly market price with an uplift factor, or at the hourly price if the prosumer chooses it, a choice that cannot be reversed. The value goes into a prosumer deposit valid for 12 months, and only a capped share of an unused deposit is paid out in cash.
Imports pay the full tariff including distribution
Under net billing a self-consumed kWh saves the whole retail price, distribution included, while an exported kWh earns a market price. That gap is wider than under the old opusty system, which is what moved Polish design toward self-consumption and storage.
Tauron and PGE tariff structures
Households run G11 flat, G12 day and night, G12w with a weekend zone and G13 across three zones. Business supplies run C11, C12a, C12b, C21, C22a and C22b, each split by single or three phase and at the 10 kW system size boundary.
01Which regime applies to my customer?+
The connection date decides it. Before 1 April 2022 the installation stays on quantity-based net metering for 15 years from connection; after that date it is on net billing. Confirm the date before choosing a compensation model, because the two produce very different payback.
02What happens to an unused prosumer deposit?+
It is valid for 12 months and only a capped share of whatever is left is refunded in cash, the rest expires. That cap is a direct argument against oversizing, and it is the part customers are most often surprised by after the first year.
03Should a customer take hourly market pricing?+
It depends on the load shape, and the choice is irreversible, so it is worth modelling both before committing. A site that consumes in the evening and exports at midday is affected very differently from one that runs through the working day.
04Which Polish tariffs are preloaded?+
Fifty-six, covering the Tauron household and business schedules along with the PGE standard rate. The tariff structures are ready to use, and the compensation mechanism should be set per project so it matches the regime the customer's connection date puts them in.
