A measurement method for parallel resistance of solar cells 1. The larger the series resistance is, the more the short circuit current drops, and the more the filling factor will accordingly; The smaller the shunt resistance, the greater the current, the more the open circuit voltage drops, and the more the fill factor drops.
Current transformer and rogowski coil
The initial resistance deviation of the resistor is familiar to everyone. Like the commonly used thick film resistors (such as 0603 package), the general accuracy is 1% or 5%. It refers to the resistance deviation at room temperature, and the initial resistance deviation is fixed after leaving the factory. For example, the nominal resistance is 100Ω, the actual measurement is 101Ω at room temperature, and the initial deviation is 1%.
