March 4, 2023: SolNet successfully develops the largest PV project in Baden-Württemberg with EnBW


With the symbolic groundbreaking and the start of construction, the SolNet team successfully completed the multi-year project development for the 80 MW solar park in Langenenslingen-Wilflingen. Initial discussions between SolNet's managing director Hans Pfisterer and Mayor Andreas Schneider took place as early as May 2018. Changes in the energy sector's framework conditions enabled the start of the concrete project development in 2019 for this flagship project, which will produce environmentally friendly electricity at market prices entirely without subsidies from the EEG. SolNet found suitable land with the family of the Freiherr von Stauffenberg, who have been local landowners for six centuries.

While initially 10 hectares were discussed, the project area gradually expanded to an impressive 80 hectares. The grandfather of Franz Schenk Freiherr von Stauffenberg had participated in the founding of the OEW in 1909, which later evolved into EnBW. It was only logical that SolNet brought EnBW on board as a partner for the project development and later as the operator of the solar park already in 2020. "The decision to work together with EnBW from an early stage on the realization of the project was exactly right," said Hans Pfisterer.

The solar park is by far the largest in Baden-Württemberg, will have an installed capacity of 80 MW, generate over 80 million kWh of green electricity each year, and thus supply over 30,000 households in Baden-Württemberg.

The electricity will be fed into the 110 kV high-voltage grid of Netze BW. For this purpose, not only was a cable route of about 4 km planned and secured, but also a suitable construction site for the necessary substation had to be found. Moreover, securing access suitable for heavy transport to the future substation was necessary. Project manager Alina Pfisterer noted: "Securing the access was a major challenge in the small-scale farmland around the substation. The last of the required contracts was signed one week before the groundbreaking." This marked the completion of the last hurdle, allowing the excavators to start rolling and the next event to be anticipated in mid-2025: the inauguration celebration of the solar park.

Actively full of energy for you

  • Project Development

    Every project is unique; otherwise, it wouldn't be a project by definition. Each project comes with its challenges that need to be mastered. We have decades of experience in developing renewable energy projects in Germany, various markets in Europe, as well as in Africa and the Middle East. This experience helps us identify risks, manage them, and define lean and efficient processes. This allows us to achieve milestones quickly and cost-effectively to reach the set goals.

    In Germany, we conduct project development for open space installations starting from 10 MW primarily as a cooperation partner of Trianel GmbH. Trianel GmbH is a network of 58 municipal utilities from Germany and neighboring European countries.

    Additionally, we develop open space installations in cooperation with EnBW and also for our own portfolio.

  • Construction

    The first solar project by the managing director of SolNet GmbH was planned, built, and installed in 1994. Decades later, with numerous construction projects both domestically and internationally, we maintain a clear focus during construction execution: A construction project is successful for us when top-quality is delivered through efficient and well-structured processes at attractive prices.

    In Germany, we construct open space systems starting from 1,000 kW and roof systems from 300 kW installed capacity. Further information about new roof system constructions can be found in the gallery.

    We are happy to analyze your area's potential and provide a free quote for the turnkey construction of a PV system.

    Alternatively, we also lease your roof space and install a PV system that we operate ourselves. In this case, you receive an annual roof lease and, if needed, cost-effective, environmentally friendly electricity from your own roof. The minimum size for a roof space suitable for leasing is 2,000 m².

  • Operation

    SolNet develops and constructs renewable energy facilities for investors and institutional clients. Some of the self-developed facilities are also transferred to our own operations. These facilities are held for the long term or offered in the market at a defined point after commissioning.

    Currently, we have ten PV installations in our portfolio that are held for the long term.

  • Maintenance

    Regular maintenance ensures optimal yields and minimizes the risk of faults. Your PV roof system also needs to undergo regular inspection and maintenance at least every 4 years.

    We are happy to take over the maintenance tasks for your PV system starting from 500 kW. Maintenance begins with yield analysis and extends to module cleaning and rectifying any identified defects.
