Ground-mounted installation: Pile driving quality goes to the very foundations of a PV array, quite literally. Helge Biernath, CEO of Sunstall, speaks to pv magazine about the importance of getting the foundations and footings of a PV array right, in the final Black Sheep article for 2016. In this, being mindful of the weather, Biernath notes, is a vital factor. pv magazine: What are the main activities of Sunstall in terms of solar project construction? We are focusing on the mechanical installation of ground-mounted arrays, across the U.S. This involves all aspects of the installation to include support for the geotechnical analysis. Once on-site we lay out the pile locations, manage and distribute all materials, drive the piles, build the racking, and install the modules. We are licensed electricians in California, so we can also do the electrical portions of a system in California. Depending on the licensing regulations in each state, we may be limited to pile and racking installation, but this is handled on a case-by-case basis with each client.
