List of the 100 largest PV-Installers Poland [2025]

Description

List of 3 large PV-Installers in Poland

Poland’s solar energy sector has been expanding at an exceptional pace. In 2024, the country added around 4 GW of new photovoltaic (PV) capacity—slightly below the 4.9 GW installed in 2023—bringing total capacity to roughly 21 GW by year-end and surpassing 22 GW in early 2025. The market, once dominated by small residential prosumer systems, is now transitioning toward commercial and utility-scale projects, supported by falling equipment costs, stable regulations, and improved grid access. Grid operator Polskie Sieci Elektroenergetyczne (PSE) has announced a PLN 64 billion transmission-investment plan through 2034, including over 4,700 km of new 400-kV lines and a direct-current corridor, designed to integrate up to 45 GW of solar power alongside wind and nuclear capacity. This infrastructure expansion is set to underpin the next phase of large-scale PV deployment. Below, we highlight three leading Polish PV installers driving the country’s solar build-out through technical expertise and large project portfolios. We will explore their expertise, project portfolios, and what sets them apart. Our list is part of an exclusive overview of the largest PV installers in Europe and gives you the opportunity to find new partners for your projects.
