ZHU, J. ... et al., 2011. Long term degradation of photovoltaic devices under real outdoor operating conditions. IN: Proceedings of the 21st International Photovoltaic Science and Engineering Conference (PVSEC-21), Fukuoka, Japan, 2011, 2pp.
Performance losses in photovoltaic (PV) systems are
a major impact on the financial viability of photovoltaic
energy. The degradation rate (RD) of photovoltaic (PV)
modules/systems is expected to be affected by the
location of where the devices are installed, which will
present different levels of different stresses. In this
paper, a database is established by collecting the RD of
PV modules/system from different locations based on
literature from 1986 to 2011. A statistical analysis of the
RD of the selected PV modules is presented. The
correlation between their degradation and environmental
strain doses are also investigated.
