AI Customer ServiceResistance is the opposition that a substance offers to the flow of electric current. There are various solar panel output parameters that can be measured and obtained during flash test, helping to judge on the performance quality of a solar panel.
At the panel's maximum power point, there is an output resistance which is the characteristic resistance of a solar cell. The maximum power is translated to the load and the panel operates at its maximum power only if the resistance of the load is equal to the characteristic resistance of the solar cell . 8.3. Shunt resistance
Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
V. CONCLUSION The description of the operating behavior of solar module by the effective internal resistance allows explicit calculation of the parameters of the effective solar module characteristic from the measured parameters Isc, Voc, Imax, Vmax Related to power of the solar generator.
The series resistance will effect on I-V Curve of solar module. As the maximum power Pmax is the product of maximum voltage and current, the Pmax will also change with change in I-V Curve. Condition 1: At series resistance Rs = 0/cm2 the cell generates maximum power and it is the product of Vmax and Imax.
Panel's I-V characteristics, inverter, battery and panel efficiencies, panel material, atomic structure and band-gap energy are some of the system factors. As for the installation factors, cable characteristics, angle of inclination, mismatch effects, fixed/tracking PV mechanisms as well as MPPT are crucial to consider.
