At MARTOR, sustainability is not just a buzzword, but a reality. As part of our comprehensive sustainability strategy, we commissioned two new photovoltaic systems at our headquarters in Solingen-Gräfrath in April and May 2025. Both systems are an essential component in sustainably reducing our carbon footprint and increasingly powering our production with self-generated green electricity.
Just under 700 kWh per day
The first plant, "Heider Hof", has been producing an average of around 280 kWh of electricity per day since 25 April. The second, "Lindgesfeld", has been active since 7 May and delivers an impressive daily output of around 400 kWh. Together, the two plants cover more than 200% of our electricity needs during daylight hours. We feed the surplus generated into the public grid as green electricity. In this way, we also support the general energy supply with renewable energy.
350 kilograms less CO₂ every day
However, the ecological effect is even more important: on a day without cloud cover, we save around 350 kilograms of CO₂ – simply by producing our own electricity and not relying on fossil fuels. These figures alone show how we can achieve a significant impact with concrete measures.
Environmental responsibility
The decision to use photovoltaics was a logical step for MARTOR. As a manufacturing company with a high level of innovation, we bear responsibility – towards our employees, our customers, the environment in general and our immediate surroundings in particular. The installation of our own solar power systems is a central component of our long-term energy strategy. The aim is to continuously increase the proportion of self-generated renewable energy and to achieve climate-neutral production in the medium term. In addition, we are contributing to the local energy transition in Solingen and to the nationwide transformation towards a low-carbon economy.
State-of-the-art technology
Technically, both systems are designed to be optimally tailored to local conditions and, in particular, our large flat roofs. They use state-of-the-art solar module technology with high efficiency and reliably supply our administration buildings, production halls and adjacent operational buildings with clean energy. The intelligent energy management system ensures that self-consumption and feed-in are efficiently regulated.
