Solar&Spar Contract GmbH & Co. KG

Founded in 2000, Solar&Spar Contract GmbH & Co. KG is a limited partnership headquartered in Wuppertal, Germany specializing in Solar.

Solar&Spar Contract GmbH & Co. KG develops and implements energy efficiency and solar power projects at schools in North Rhine-Westphalia through citizen-financed contracting models. The company combines rooftop photovoltaic installations with comprehensive energy efficiency retrofits including lighting upgrades, HVAC system renovation, and in some cases combined heat and power plants. Operating under the 100,000 Watt Solar Initiative for Schools in NRW, the company finances projects through citizen participation at returns of approximately 5-6%, with energy cost savings guaranteeing repayment over 20-year contracts. The initiative was conceived by the Wuppertal Institut für Klima, Umwelt, Energie, which provides scientific oversight. Since 2002, the company has successfully implemented four major projects at German schools, resulting in over 2.2 million kWh of solar electricity generation and combined CO2 savings exceeding 2 million kg annually.
