What is shunt resistance in solar cell?
Shunt Resistance. Such a diversion reduces the amount of current flowing through the solar cell junction and reduces the voltage from the solar cell. The effect of a shunt resistance is particularly severe at low light levels, since there will be less light-generated current. The loss of this current to the shunt therefore has a larger impact.
What is a solar charge controller and shunt controller?
A solar charge controller is a device that manages the charging of a battery from a solar module or array of modules. Solar charge controllers come in three types, though the market is dominated more and more by just one of those. A shunt controller is just an ON/OFF switch.
How does a shunt controller work?
A shunt controller is just an ON/OFF switch. When the battery voltage is low (ie needs a charge) the switch turns ON and energy flows from the solar array to the battery. When the battery voltage is high (ie charged) the switch turns OFF and charging stops.
How does a solar battery shunt transistor work?
At this point, a shunt transistor will turn on, shorting out the solar array, halting any further battery charging. When the battery voltage drops to the charge resumption set-point, the shunt transistor will turn off and charging will resume.
