About
Founded in 2009, Optimasolar Solothurn is a co-op headquartered in Solothurn, Switzerland specializing in Solar.
OptimaSolar Solothurn is a registered cooperative that has planned, financed, and operated solar installations for over 15 years. The company rents roofs from municipalities, businesses, farms, and private homeowners to install solar systems and supply renewable electricity directly to buildings. They offer solar energy products including subscription-based solar electricity (minimum 1000 kWh annually) and solar vignet products for households, businesses, electric vehicles, and bicycles. OptimaSolar operates as a certified electricity provider selling ecological added value separately from physical power, certified through Pronovo's origin certificates (HKN). Customers receive proof-of-origin certificates and solar vignettes to document their renewable energy commitment. The company supports the energy transition by enabling construction of additional solar installations through customer electricity purchases.
