Low-Concentration Linear-Array Photovoltaic System with Two-axis Sun Tracking

In a concentrator photovoltaic (PV) system, high concentration causes a decrease of electrical output, since the temperature of the PV cell increases. A linear-array photovoltaic system (LAPS) with a relatively low concentration using a cylindrical mirror was developed. In this system, the sunlight was concentrated on a linearly-arrayed PV system with 7 mono-crystalline silicon PV modules. The LAPS was mounted on a two-axis sun-tracker system. The electrical efficiency was approximately 11% under typical operating conditions.
