Thermal performance of the SunPower Alpha-2 PV-concentrator

Summary form only given. Concentrator photovoltaic (CPV) systems typically rely on passive airflow and a low thermal resistance cell package to maintain safe and reliable cell operating temperatures. Due to the high heat flux associated with the concentrated irradiance, it is important to validate operating temperatures in typical field environments. This work focuses on a full thermal characterization of the SunPower Alpha-2, 7× linear concentrator system as well as a side-by-side thermal comparison to Sunpower 1-sun PV modules mounted to the same rotational axis.
