Today, SMA Solar Technology AG inaugurated its new solar inverter factory. With the inverter factory, SMA is extending its production capacities to four gigawatt and is continuously expanding its successful strategy of flexibility. In the opening speech Chief Executive Officer Günther Cramer pointed out that the new facilities were setting a new trend in terms of CO2 neutral fabrication sites.
About 500 guests attended the inauguration ceremony. Silke Lautenschläger, the Hessian Minister for Environment, Energy, Agriculture and Consumer Protection, gave the official speech.
SMA’s new inverter factory which has already been producing since March of this year, is setting new standards in every respect: an annual production capacity of up to four gigawatt on 18,000 square meters make it the world’s largest solar inverter factory.
The new factory has the lowest possible energy requirements together with the highest efficiency of consumed energy. Among other standards the building thus complies with the low-energy building concept. In addition, a reduced energy consumption of the production and testing facilities is achieved through efficiency measures in the production process. An optimal use of daylight, intelligent ventilation as well as the use of storage units for heating and cooling complement the energy and building concept.
The electricity and heat demand is covered by renewable energy sources: an integrated PV system with a power of around 1.1 megawatt and a combined heat and power plant fueled with bio-gas generates CO2-neutral electricity.
“Green electricity” is additionally purchased in order to cover the total energy consumption of the production facilities. In the long run the CO2 balance will be zero by installing additional photovoltaic systems nearby.
The required heat is produced with the biogas-powered combined heat and power plant. At the same time, the waste heat coming from the compressor for the air powered tools and the lifting gear is utilized for the heating system. The additionally required heat demand is covered by using district heating from a nearby waste incineration plant.
Sufficient cooling is provided as well: an absorption refrigeration machine uses the heat of the combined heat and power plant for air conditioning.
In the new factory the process steps in the production have been completely re-designed in terms of efficiency. Entire production lines can be extended or reconfigured for other device types within shortest notice. This provides maximum flexibility in addition to the “just-in-time” production without warehouse.
“The inverters being the heart of every photovoltaic system already significantly contribute to an emission-free energy supply”, Günther Cramer, Chief Executive Officer of SMA Solar Technology AG, explains. “With our CO2-neutral inverter production we even go one step further. Today we can show that an advanced production on industrial level can be done with a minimal environmental footprint. As the worldwide leading producer of solar inverters we now intend to initiate a trend towards CO2-neutral factories”.
