Power performance characterization of multi-crystalline silicon solar cells and its module at outdoor exposure

摘要

Outdoor power performance measurements of silicon (Si) solar cells and its assembled module were carried out at the coastal site of geographical location of 12.0107 degrees Latitude and 79.856 degrees Longitude, of Puducherry, India. Measurements were analyzed in comparison with the daily solar illumination data obtained by an optical pyranometer deployed with global measurement condition. It was found that the module required similar to 3 times more illumination to stabilize in its output voltage than the requirement of an individual cell and exhibited 11.35% loss in its efficiency compared to its STC value. Proposed operation of 5.30hours was found resulting in an output rating fixed at similar to 40% from its 100% full capacity.
