Meet the PEG: A super lightweight fixed-tilt solar system now certified for the United States market
Jurchen Technology has had its innovative PEG system certified according to the US UL-2703 standard and debuted its innovative fixed tilt PV system in the United States at Solar Power International 2019. The certification was carried out by Intertek US.
“This certification enables us to enter into the US market. The extremely efficient area utilization of up to 1.7 megawatts per hectare (0.71 megawatts per acre) makes our system particularly interesting for the US market, as space close to network connection points in the USA is not only rare but also very expensive,” says Michael Jurchen, CEO of Jurchen Technology GmbH.
Since its introduction at the Intersolar Europe trade fair in 2018, Jurchen Technology has delivered this revolutionary system to a number of locations in Germany and the Netherlands, as well as Israel, Africa and Australia. The substructure is particularly popular in Australia, where it is currently being utilized to provide the countries first series of unsubsidized utility scale solar projects. By the end of 2019, around 50 solar plants based on the innovative PEG substructure will have been built.
How it works
The PEG substructure is a low-height solution, which sits on slender steel slats instead of high, solid-steel girders. The lightweight construction means no foundations are required. This reduces the amount of materials required to less than 50 percent of any conventional solution. Less material and simple construction also lead to reduced transport costs, which is a significant benefit considering the huge distances that need to be covered in the US.
Furthermore, no cable trenches or concrete work is required, which eliminates the need for heavy machinery. What’s more, the labor costs required for such a quick installation job are much lower too.
“With this PEG substructure we can significantly reduce the overall costs – by over 40 percent in terms of the investment costs and 20 percent in terms of the running costs,” says Michael Jurchen.
Thanks to the unique design, this PEG system is adaptable to individual customer requirements, making it suitable for installation anywhere in the world. With the exception of the “ground pegs, the entire construction process, including DC wiring, is executed above ground, which means it can be installed in all kinds of different terrain.
For instance, the system is suitable for power generation in remote areas with difficult access or areas with size limitations or narrow profiles. The size of the plant is also easily scalable. Major PV power plants in the multi-megawatt range are equally as achievable as small to medium-sized solar power plants with just ten kilowatts peak output for commercial and industrial purposes.
