Introduction
Wieland Group, a leading manufacturer of copper products, has inaugurated a solar park in Erbach, southern Germany, that is set to generate 29 GWh of renewable electricity annually. This investment aligns with the company’s sustainability goals and commitment to reducing carbon emissions.
Project Overview

Investment Details
The company has invested nearly EUR 20 million (approximately USD 21.7 million) in the solar park project. The setup includes:
- 48,000 solar modules
- 82 inverters
- 14 transformer systems
- Construction of a 110/20 kV substation
Location and Size
The photovoltaic system spans 24 hectares, situated about 5 km from Wieland’s headquarters in Ulm and 15 km west of its largest production site in Voehringen. This strategic location enhances the company’s ability to harness renewable energy effectively.
Environmental Impact
Carbon Emission Reduction Goals
The installation of the solar park is part of Wieland’s commitment to reducing its carbon dioxide emissions by over 46% by 2030 compared to fiscal 2018/19 levels. The long-term objective is to achieve net-zero emissions across the entire value chain by 2045.
Contribution to Energy Needs
The electricity generated at the Erbach solar park will account for approximately 8% of the total annual energy required for all Wieland sites in Germany. This significant contribution underscores the company’s efforts to transition towards sustainable energy sources.
Future Energy Initiatives
Additional Solar Projects
Wieland Group is also collaborating with energy firm Vattenfall on another solar park currently under construction in Nauen, Brandenburg. This facility is expected to supply an additional 46 GWh of electricity annually starting in 2025, which will help meet another 13% of the company’s energy needs in Germany.
Focus on Renewable Energy Expansion
Looking ahead, Wieland plans to expand its share of renewable energy in its electricity mix. In the EU, the company will primarily focus on wind energy projects. In the key North American market, Wieland is exploring various options for generating renewable energy internally.
Conclusion
The launch of the solar park in Erbach marks a significant step for Wieland Group towards achieving its sustainability targets. By investing in renewable energy, the company is not only reducing its carbon footprint but also ensuring a more sustainable energy future for its operations in Germany and beyond. As Wieland continues to explore and implement renewable energy solutions, it sets a benchmark for other industries aiming to transition to greener practices.
