Solar panels output more than their nominal voltage. For example, a 12v solar panel might put out up to 19 volts. While a 12v battery can take up to 14 or 15 volts when charging, 19 volts is simply too much and could lead to damage from overcharging. Solar charge controllers aren''t an optional component that delivers increased efficiency.
Will a 40-watt solar panel charge a 12-volt battery. A 40-watt solar panel can charge any size 12v battery but it can only add 16 Amps to the battery bank in a whole day. 12v batteries come in different sizes so with the help of a charge controller you can store the DC power produced by the solar panels in the battery bank to later use .
Solar panel selection. Choose a 12V solar panel with an appropriate power rating (in watts) and maximum current output (in amperes). The higher the wattage, the more power the panel can generate. For example, if you have a 12V, 200W solar panel, it can produce a maximum current of around 16.7A (200W / 12V) under ideal conditions.
For a 12V lithium-ion battery, a 150-watt solar panel can charge the device (100 Ah capacity) in 10 hours. But if you use lead acid battery, it will take a 100-watt panel. To find the right panel wattage to charge a 12V battery, you must answer these two questions:
