Once the Charge Controller Converts those V from the solar array down to the ~ V necessary to charge a V battery bank, the charge controller will be putting out A to charge the …
If a 100-Watt solar panel is used to power a battery, a solar charge controller is necessary. Some small solar systems include only a single 100-watt panel and a battery. These systems need solar charge controllers to regulate the current entering the battery. Are Charge Controllers Needed for 7-Watt Solar Panels? You don''t need a charge ...

The real difference is the size of the solar panel wattage and charge controller amperage needed. In Tuscon AZ in winter receives 5.6 Sun Hours in December and January. So if using a MPPT charge controller with a system efficiency of 66% the solar panel wattage required = 1000 wh /.66 / 5.6 h = 270 watts.
If you were to get a 20A PWM controller, you would be able to regulate a solar panel bank of up to 320W for 12V batteries, and 640W for 24V batteries.The PWM controller can also be used to connect solar panels to a battery bank of 12V batteries, provided that the batteries are the same size and that they are in good condition.
With Pulse Width Modulation controllers, the voltage from the solar panel has to match the voltage from the battery. If a solar array has a voltage of 17V and the battery bank has 14V, the solar controller can only use 14V reducing the amount of power.
A protection ratio of at least 1.25 is recommended, which means that you can average the current from the panels by 1.25 and then equate it to 30 amps. E.g., five 100 watt panels will be 5.29 x 5 = 26.45 amps in parallel. 26.45 Amps x 1.25 = 33 amps, and …
