Adjusting Device of Solar Tracker for Testing Off-axis Beam Damage of A Concentrator Photovoltaic (CPV) Module

Abstract

An adjusting device is provided for solar tracker. The adjusting device is used for testing off-axis beam damage of a CPV module. A universal transmission unit is comprised for adjustment. Thus, a CPV module is exactly focused to a predestined position. Furthermore, a focusing point of the CPV module can be biased to the predestined position for testing off-axis beam damage.
