The results prove that the performance of the Photovoltaic Cell Equivalent-Circuit Models is influenced by solar irradiance and temperature. This suggests a new approach to enhance the accuracy of PV output prediction.
Furthermore, the SDM performs well with low fluctuations of temperature and the DDM is more appropriate for medium and high variations. The results prove that the performance of the Photovoltaic Cell Equivalent-Circuit Models is influenced by solar irradiance and temperature.
Conclusions Solar irradiance is of utmost importance for PV energy generation and can be affected in different ways. To a lesser extent, it is the variation of sunlight reaching the top of the atmosphere due to the sun cycle as well as the variation in sun-earth distance.
We learned in our review of EME 812 how irradiance and temperature affect the output of a PV cell. A quick recap will tell us that when all parameters are constant, the higher the irradiance, the greater the output current, and as a result, the greater the power generated.
Also, this model is more suitable for temperature variation except for the Poly-Si technology in high temperature changes. Briefly, these curves show that the low-irradiance levels engender high errors in the PV output power with a value of 8.40%. The lowest error closed to 0.10%. is presented at the short circuit currents. Fig. 8.
The irradiance of the sun, also known as solar irradiance, plays a significant role in the power output of PV-modules. Under standard test conditions (STC), PV modules are specified at a solar irradiance of 1000W/m². The amount of solar irradiance available in a specific location determines how much power a rated solar panel can produce in that location.
