Solar Charge Controller
Typically 18V Solar Panels use a 12V controller but you can have other configurations such as 36V panels that will use a 24V controller and 72V panels use a 48V controller. The next thing you will need to do is divide the wattage of your solar panels by the battery bank voltage to get an estimate of how many amperes the Solar Charge …
Reduce Solar Panel Voltage (Volts + Calculations)
If you had a 25-watt solar panel and wanted to charge a 12volt car battery, you would need to have 5-8 hours of direct sunlight, which is how long it would take for the panel to charge the battery. It would likely take longer in the real world because of the ebb and flow of energy produced by a solar panel throughout the day.
