SUSTAINABLE ELECTRICITY FROM SUNLIGHT THROUGH METZNERS’ OWN PHOTOVOLTAIC SYSTEMS
December 9th, 2021
As a future-oriented company, Metzner Holding attaches great importance to environmental awareness, sustainability and climate protection. We cover 90 — 100 % of our electricity requirements from our in-house photovoltaic system. Metzner Maschinenbau GmbH, Metzner E‑Mobility and ramatech systems GmbH have been drawing their electricity from our photovoltaic system since 2013.
The goal of acquiring a photovoltaic system was therefore not only economic — to save money in the long term, for example — but had much more ecological motives. Why? We will explain this in a short article on photovoltaic systems and their sustainable contribution to the energy transition.
A photovoltaic system reduces emissions of air pollutants
Unlike coal or gas, the generation of electricity by photovoltaic systems does not rely on fossil fuels, which contributes to reduced CO2 emissions. This is in contrast to emissions such as sulfur, carbon and nitrogen oxides, as well as dust, which escape into the environment during electricity production in gas and coal-fired power plants. The use of a photovoltaic system reduces the emission of air pollutants and decreases the attack on the ozone layer.
Recycling of photovoltaic systems
Up to 95% of solar systems can be recycled — another advantage when it comes to sustainability. The recovered material can thus be reused for the production of new systems. Defective modules are installed in new, functional photovoltaic systems after recycling.
Positive eco-balance
To determine the environmental balance of the components, the Energy Return on Energy Invested (ERoEI or EROI; translated harvest factor) is used. This describes the relationship between the energy used and the energy invested and is an indicator of the energy payback of various technologies.
The ERoEI value for photovoltaic systems is on average 10. Consequently, a conventional photovoltaic system produces 10 times more energy during its useful life than was invested in the production of its individual components.
An indication of the sustainable operation of photovoltaics is the overall energy balance, which is very positive over the entire service life.
FIND OUT MORE ABOUT US
With over 30 years of experience in the production of series and special machines, we offer our customers competent solutions and concentrated know-how. A medium-sized company culture, short decision-making processes and a respectful environment enable our employees to contribute their own ideas and experience to the development of the machines.
The hydraulics hiss quietly, silver tablets moving very quick — about the size of an A4 sheet of paper — from left to right to the next station. The orange cable is clamped, a tool moves over it and presses the connector in place. 21 work steps a workpiece goes through a workpiece in this 20-meter-long meter long machine, which is installed Metzner E‑Mobility in Neu-Ulm, Germany.
That’s possible with Metzner. A holding company that has several subsidiaries. What is behind it? Which companies are involved and why? It’s all about cables. There is an entire value chain behind it. Successful work through cooperation and interaction that offers added value to the customer. This is the approach taken by Metzner Holding.
In March 2019 EQ ZERT certified the quality management system of Metzner Maschinenbau GmbH according to ISO 9001:2015. The management of the internationally active, medium-sized mechanical engineering company sees this as confirmation that it is on the right track with the company policy it has been pursuing for many years.
eu-Ulm, January 30, 2019: In recent years, Metzner Maschinenbau GmbH has continuously invested in the expansion of the future-oriented field of e‑mobility.
Neu-Ulm, August 23, 2018: Everyone is talking about the transition from combustion engines to electric motors. In the course of this far-reaching change, there is no question that the production of electric vehicles will increase significantly in the coming years — even if it will probably still take some time before the means of transportation can be found on the roads everywhere.
