The 6000NT dual-axis solar tracking system from DEGERtraker helps align the solar modules to the brightest source in the sky to guarantee maximum yield. The manufacturer says its systems generate up to 45 percent more energy than fixed installations.
The tracker’s rails are made of impact extruded aluminum by Hydro Aluminum Extrusion America. This material combines efficient consumption of raw material, comparatively low costs and rapid development cycles. Aluminum is corrosion resistant and highly stable. Therefore, the systems withstand even high wind speeds, practically do not bend at all and have a long service life.
Apex Construction Services has built four solar fields in Tennessee that use 112 of the trackers. Each solar project is equipped with 28 of the trackers and thus designed for a power of up to 200 kW. Apex says it was impressed by how quickly the construction teams managed to install the first tracker. “Our team got really excited about the simple assembly and DEGERenergie’s support during installation,” says Greg Brock, Co-Founder and principal at Apex. ”We are enthusiastic about the DEGER trackers and we are already planning further projects with our partners.”
“DEGERenergie’s design calls for very tight tolerances,” said Allan Bennett, vice president of solar market development for Hydro’s Extrusion North America unit. “Our engineering, working with DEGERenergie’s staff in Germany and production groups here, had to go above and beyond the usual to get this just right. Now we are working with them on some alloy choices that might help us make it even tighter than they originally called out.”
