Wuppertal – The installation of the two PV systems began at the end of 2024 with the first assembly work. A total of 2,630 solar modules were then installed on two E/D/E building roofs, covering an area of 5,260 square meters.
With the new photovoltaic system, E/D/E is focusing on sustainability, cost-effectiveness and in-house production: together, the PV modules are expected to generate over one million kWh of electricity per year, with a module output of 1,183.5 kilowatt peak (kWp). The PV system therefore produces a proportion of the electricity for E/D/E. As a result, the company avoids the emission of around 370 tons of CO2 per year. According to established calculation bases*, this corresponds to the binding capacity of around 30,000 beech trees. E/D/E continues to cover its other requirements by purchasing certified green electricity externally.
In line with the company’s guiding principle “Successfully hand in hand”, E/D/E combines ecology and economy with the PV system: by using the self-generated solar power, the company significantly reduces its energy costs in the long term. At the current electricity price including taxes, E/D/E expects the investment in the PV system to pay for itself after around five years. In addition, the PV system strengthens the company’s own energy supply. This makes the company more resilient to price fluctuations and supply risks – an important step towards a future-proof, increasingly self-sufficient energy supply. After the first five months, the results are positive: “So far, we have generated over 750,000 kWh of electricity. We are therefore optimistic that we will produce more than 25 percent of our total annual electricity consumption ourselves,” says Christian Schäfer, Head of Technical Building and Energy Management at E/D/E, who has been involved in the PV system project from the outset.
Responsibility and commitment
E/D/E focuses its processes on avoiding and reducing the use of resources and returning materials and products to the cycle. The family-owned company has therefore already implemented numerous measures in the past, such as the installation of LED lighting with sensors and presence detectors, the use of green electricity, the introduction of energy management and various sustainable processes in IT. “With the new PV system, we are reducing our ecological footprint and thus contributing to climate protection. This measure is therefore another important step towards a sustainable future and underlines our commitment to environmental protection and resource conservation,” says Jennifer Träptau, Sustainability Officer at the E/D/E Group.
