We have developed our tracker and the methodology of installation to cut significant costs out of the balance of system. Minimizing site prep, the plug-and-play assembly of the tracker, & related components can generate an additional savings over other tracker installations. That translates into cost/kWhour, not cost/kW. Plus, we help with site evaluation, installation training, commissioning support and monitoring of solar power plants. Bottom line: If you are not using PV Trackers for your ground-mount system you are not capturing the lowest cost/kWhour.
