Ostrom and Soly announce strategic partnership

Berlin/ Düsseldorf, April 24, 2023 - Ostrom and Soly have agreed on a strategic partnership to combine their strengths and create synergies. Effective starting April 2023, customers of both companies will reap the benefits of the collaboration.

As part of the partnership, Ostrom will offer tariffs that suit the needs of the photovoltaic company's customers. The Ostrom tariff will allow Soly's customers to meet their energy needs with hourly electricity rates that also take advantage of local storage capacity.

Soly, in turn, will offer Ostrom customers exclusive conditions for the installation of a photovoltaic system as a complete package, including comprehensive advice, installation and maintenance. Through this cooperation, customers can enjoy high-quality products and services at attractive prices from both companies.
