Abstract :
A report on a 15 kWp grid-connected photovoltaic system employing thin-film amorphous silicon modules is presented. The system performance monitoring and diagnostics were conducted for nearly a year of operation to determine the array efficiency, array power degradation, and system reliability. The system installation, description, and reliability are reported. The data show that after one year the power output of the photovoltaic array has degraded by about 16% of its initial value and the array peak power efficiency is 4.5%
