Photovoltaic tracker, also known as solar tracker, is the power device that keeps the solar panel directly facing the sun at any time, so that the light of the sun shines vertically on the solar panel at any time. Using this device tracker can significantly improve the power generation efficiency of solar photovoltaic modules.
SolarCells and Modules are the core components of photovoltaic power generationsystems, and their development level directly determines the development levelof photovoltaic power generation. Since the invention of solar cells in 1954,after more than half a century of development, there are currently a widevariety of solar cells, and their conversion efficiency has also beensignificantly improved.
