Elsterheide solar park puts faith in Swiss Quality with SolarMax inverters and monitoring system

With an overall output of 20 MW, the Elsterheide solar park is the largest project in the world for SolarMax. The installation work for the 54 inverters was carried out by general contractor Gräss Solartechnik GmbH & Co. KG. The plant owner is Sunflower (Luxembourg) Light Energy & Science Ltd. The MaxComm monitoring platform ensures the smooth operation of the plant.

Previously only known for Lausitz linseed oil, Hoyerswerda has had an added attraction since January 2012: the Elsterheide solar park. This modern, open air PV plant with an overall output of 20 MW extends over 460,000 square metres. A total of 86,960 polycrystalline Sunowe modules from the Zhejiang Sunflower company have been installed. Distributed over 18 Power Stations are 54 330TS-SV SolarMax inverters – each with a rated output of 330 kW. This makes the Elsterheide solar park the largest project for SolarMax to date. Solar energy from Hoyerswerda has been fed into the German national grid since January 2012.

Gräss Solartechnik GmbH & Co. KG has been specialising in the assembly of open-area PV plants for many years now. And for projects of this size, Gräss has already drawn upon the expertise of SolarMax on a number of occasions. Both companies are in agreement that quality, reliability and precise cooperation are the key to a project such as this.

A particular challenge at the Elsterheide solar park for both companies, was the extremely short project time: there were only ten days between the signing of the contracts and the start of the project. All parts had been supplied within a period of only four weeks. "This kind of success under such time pressure is only possible with the help of reliable partners. Here, the Swiss inverter manufacturer SolarMax has really proven its flexibility and speed," explains Managing Director Harald Gräss.

The clever SolarMax monitoring system takes care of quality assurance for the PV plant. The entire plant, right down to each individual string, can be monitored via the MaxComm communications platform – either by the plant operator themselves or by SolarMax in the form of a service provision. This means that perfect operation is guaranteed at the solar park for decades.
