Abstract:
Renewable energy sources play an important role in electricity generation.
Various renewable energy sources like wind, solar, geothermal, ocean thermal,
and biomass can be used for generation of electricity and for meeting the daily energy
needs. Energy from the sun is the best option for electricity generation as it is
available everywhere and is free to harness. Manufacturers of PV modules provide
ratings for conditions referred to as Standard Test Conditions (STC). These conditions
rarely occur outdoors. The efficiency of PV modules depends on its temperature. The
temperature of PV modules is integration of few factors and one of them is ambient
(air) temperature. Therefore the air temperature has an influence on the amount of
produced energy from PV systems.
This thesis to study the effect of temperature on the performance of PV solar
modules. And hence then effect of the sizing of PV systems.
Was used outdoor test method for the crystal silicon PV module to measured the
electrical parameters of PV module at constant solar radiation 1000W/m2 and
different module temperature, from the test found that the power and efficiency
decreases with increasing temperature, the power temperature Coefficient for crystal
silicon module is -0.429 %/C. And the temperature loss was 13% when the ambient
air temperature was 29oC, and 20% when the ambient air temperature was 45oC.
According to the results that you should take the effect of temperature into account
when designing PV systems. As you leave enough space when installing PV array
helps to cool the PV module and thus reduce the temperature losses
