Abstract

Concentration photovoltaic (CPV) systems are seen as a shortcut to achieve lower photovoltaic (PV) electricity costs/kWh. Within the available CPV configurations, V-trough systems are likely to succeed in the short term since they are less demanding in terms of tracking accuracy and due to their ability to make use of standard PV modules, a well-known and developed technology. However, silicon standard modules were initially designed to operate under 1 sun conditions, facing some challenges when integrated in CPV systems. The present work aims to demonstrate that such application is efficient up to a few suns and also to analyze possible accelerated modules degradation rates. For such analysis we have used a prototype based on the DoubleSun® technology: a 1.9x concentration V-trough system, integrating 2-axis tracking system and making use of conventional silicon modules.
