| Summary: | The performance of photovoltaic (PV) module is affected by outdoor
conditions. Outdoor testing consists installing a module, and collecting
electrical performance data and climatic data over a certain period of time.
It can also include the study of long-term performance under real work
conditions. Tests are operated in URAER located in desert region of Ghardaïa
(Algeria) characterized by high irradiation and temperature levels. The
degradation of PV module with temperature and time exposure to sunlight
contributes significantly to the final output from the module, as the output
reduces each year. This paper presents a comparative study of different
methods to evaluate the degradation of PV module after a long term exposure
of more than 12 years in desert region and calculates uncertainties in
measuring. Firstly, this evaluation uses three methods: Visual inspection,
data given by Solmetric PVA-600 Analyzer translated at Standard Test
Condition (STC) and based on the investigation results of the translation
equations as ICE 60891. Secondly, the degradation rates calculated for all
methods. Finally, a comparison between a degradation rates given by Solmetric
PVA-600 analyzer, calculated by simulation model and calculated by two
methods (ICE 60891 procedures 1, 2). We achieved a detailed uncertainty study
in order to improve the procedure and measurement instrument. |
