Genossenschaft OptimaSolar Surselva

Summary

About the company

The cooperative aims to contribute to sustainable electricity production by creating and operating photovoltaic or comparable systems for the generation and grid feed-in of electricity, thereby enabling cooperative members and other electricity consumers to cover their own electricity needs with solar power. It also aims to raise awareness and understanding of renewable energies among the population (residents and non-residents) through workshops, training sessions and information events. The cooperative can acquire or sell properties, enter into any business and conclude contracts that are suitable to promote its purpose. In addition, other tasks that serve the purpose of the cooperative can be taken over.
