Follow these 6 steps to calculate the estimated required solar panel size to recharge your battery in desired time frame. .
Here's a chart about what size solar panel you need to charge different capacity 24v lead-acid & Lithium (LiFePO4) batteries in 6 peak sun hours using an MPPT charge controller. .
Here's a chart about what size solar panel you need to charge different capacity 12v lead-acid and Lithium (LiFePO4) batteries in 6 peak sun hours using an MPPT charge controller. The size of a solar battery charger you need depends on two things: the battery’s capacity (measured in Ah or mAh) and the solar panel’s power output (measured in Watts). As a rule of thumb, a solar charger with an output of 10 Watts should be sufficient for a small to medium-sized 12V battery. [pdf]
