What They Do

WI SOLAR GmbH specializes in comprehensive photovoltaic building solutions for commercial, industrial, retail, logistics, and construction companies. The company offers a full range of services from project development, installation, and service to maintenance, placing special emphasis on tailored solutions rather than a generic "renewable energy" label (source: wi-solar.de). As a full-service provider, WI SOLAR delivers a 360-degree package that includes consulting, analysis, planning, implementation, operation, as well as service and maintenance (source: wi-solar.de). The company focuses on energy concepts for commerce, trade, industry, and logistics and also offers "Wi INVEST," a solution for customers who want to benefit from solar energy without making their own capital investments (source: wi-solar.de). Their target audience primarily includes businesses and property owners with high electricity demands, especially in construction, trade, industry, retail, and logistics sectors (source: wi-solar.de).

Projects & Track Record

WI SOLAR boasts over 15 years of experience in planning and implementing high-quality rooftop photovoltaic systems for businesses, focusing on commercial rooftop systems, green roofs, ground-mounted systems, battery storage, and charging infrastructure (source: wi-solar.de). The company also provides comprehensive operational support through monitoring, service, and maintenance (source: wi-solar.de). According to ENF Solar, WI SOLAR operates in Germany and delivers both smaller systems and installations exceeding 1 MWp capacity, including battery storage (source: enfsolar.com). The Wi INVEST division installs and operates solar systems on company roofs for clients who prefer not to make their own investments (source: stadt-kaisersesch.de).

Recent Developments

In October 2025, WI SOLAR and TESVOLT announced an enhanced collaboration focusing on the commercial use of renewable energies with an emphasis on storage solutions, highlighting WI SOLAR’s active role in the storage-supported photovoltaic market (source: pv-magazine.de). In 2024, the company continued to be led by managing directors Andre Steffens and Sven Endris and was described as a specialist in PV rooftop systems for commercial, retail, industrial, and logistics sectors (source: wi-solar.de).

Working There

WI SOLAR offers a variety of roles in technical planning, project management, installation, service, as well as commercial functions, reflecting the company’s specialized EPC and service model (source: wi-solar.de). The workforce operates both at the headquarters in Kaisersesch and at various project sites across Germany (source: kununu.com). The company values a technically oriented corporate culture with a close-knit team of engineers, TÜV-certified experts, service technicians, and master craftsmen (source: wi-solar.de).
