A charge controller or charge regulator is a voltage and a current regulator to keep batteries from overcharging. It regulates the voltage and current coming from solar panels going to the battery. A charge controller is usually useful.  A fully charged "12 volt’" battery is around 12.7 volts at rest, so the panel has to put out at least that much under worst case conditions. Contrary to intuition, solar panels work best at cooler temperatures. 

Roughly, a panel rated at 100 watts at room temperature will be an 83 watt panel at 110 degrees. If you use a standard controller, it will often work with high voltage panels if the maximum input voltage of the charge controller is not exceeded. However, there is going to be a lot of lost power, from 20% to 60% of what your panel is rated at. Charge controls come in all shapes, features, sizes and price ranges and in 3 general types. Circuitry that functions as a charge regulator controller may consist of several electrical components or may be encapsulated in a single microchip, an integrated circuit usually called a charge controller IC or charge control IC. We invite you to find out more about the low dropout voltage (LDO) solar charge controller that uses a simple differential amplifier and series channel MOSFET linear regulator. Voltage output is adjustable and it’s mainly intended for charging 12V lead-acid batteries.
