ABSTRACT: The explosive technological
improvement of photovoltaic systems as well as the necessity of populations to
come to less expensive energy sources, that have led to an implosion at the
level of solar panel manufacturers. This causes a large flow of these
equipments to developing countries where the need is high, without any quality control. That conducted an experimental
investigation on the performance characteristics of a 250 wp monocrystalline
silicon photovoltaic module in other to check the verification and quality
control. Most of these PV panels which often have missing informations are
manufactured and tested in places that are inadequate for our environmental and
meteorological conditions. Also, their influences on the stability of
internal parameters were evaluated in order to optimize their performance. The
results obtained at maximum illumination
(1000 w/m2) confirmed those produced by the manufacturer. The
analysis of these characteristics showed that the illumination and the temperature
(meteorological factors) influenced at most the stability of the internal
characteristics of the module in the sense that the maximum power increased
very rapidly beyond 750 w/m2 but a degradation of performance was
accentuated for a temperature of the solar cells exceeding 50°C. The
degradation coefficients were evaluated at -0.0864 V/°C for the voltage and
at -1.6248 w/°C for the power. The 10° inclination angle of the solar panel proved to be ideal for optimizing overall
efficiency in practical situations.
