How Many Batteries Do You Need for a 100-Watt Solar Panel?
One 360Wh (12V, 30Ah) battery is large enough to use with a 100-watt solar panel. This battery will recharge in about 4.5 hours in good sunlight and can be completely recharged in a single day. Larger batteries will take longer to recharge but may be ideal for a backup power source.
Check out my table below, where I show the recharging times of different batteries with a 100W solar panel.
How Fast Will a 100-Watt Solar Panel Charge a Battery?
A 100-watt solar panel will charge a 12V, 30Ah battery in 4.5 hours, a 12V, 100Ah battery in 15 hours, and a 12V, 150Ah battery in 22.5 hours; however, charging times vary depending on weather conditions, solar panel and charge controller efficiency, and the length and gauge of wire used.
|Battery Size||Charging Time|
|360Wh (12V, 30Ah)||4.5 hours|
|600Wh (12V, 50Ah)||7.5 hours|
|1,200Wh (12V, 100Ah)||15 hours|
|1,440Wh (12V, 120Ah)||18 hours|
|1,800Wh (12V, 150Ah)||22.5 hours|
|2,400Wh (12V, 200Ah)||30 hours|
12-volt solar panel systems require thicker wiring to transfer the energy (measured in amps) to the battery. The thinner the wire, the less efficient the system is as a whole.
Long wires/cables also decrease the efficiency of the system because energy is lost through the power transfer from the solar panel to the battery.
