ABSTRACT
Performance characteristics data of solar photovoltaic
(PV) cell/module are conventionally obtained
under standard testing conditions. In the present work, the performance of PV modules
under extreme temperatures and insolations experienced in State of Qatar was utilized
to aid presenting a simplified characterization approach for the special case of
arid environmental conditions. The chosen model was the well-known single diode
model with both series and parallel resistors for greater accuracy. The modeling
technique was validated by comparing the numerically calculated electrical characteristics
with experimentally obtained data using two approaches: a single indoor fixed monocrystalline
PV module inside a solar simulation chamber which physically simulated different
weather scenarios by changing irradiation intensities and temperature, and a set
of outdoor fixed polycrystalline PV modules. The result of the indoor experiment
was presented in form of performance curves, and the outdoor experiment results
in a monthly accumulated power production chart format. Both illustration types
showed acceptable tolerance.
