Polska Energetyka Słoneczna Sp. z o.o. is a developer of renewable energy sources. The core of our business is investment in ground-mounted photovoltaic, wind and energy storage systems.

Our idea is to support the transformation of the Polish energy sector towards climate neutrality. Due to the fact that one of the most environmentally friendly sources of electric energy generation is solar energy, this is where we place our greatest hopes. By relying on it, we not only support positive changes in our environment but also create cheaper electricity.
Our team has more than 20 years of experience in preparing, building and managing such projects. We have gained competence both in Poland and abroad.


We are currently developing 38 projects with a total capacity of more than 5,000 MW and employ a team of 50 specialists in the design and construction of RES investments, energy trading and business analysts.
