Industrial design and implementation of a large-scale dual-axis sun tracker with a vertical-axis-rotating-platform and multiple-row-elevation structures

A dual-axis tracked Photovoltaic (PV) system can produce up to 30% more electrical energy in a year as compared to a fixed-tilt PV system. To be economically feasible, a sun-tracker must also be accountable for the cost effectiveness, durability and long-term reliability despite the gain in electrical yield. To achieve this purpose, in this paper, we are reporting a practical industrial design of a large-scale dual-axis sun-tracker consisting of...
