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. A 12V battery's capacity can range from as low as 50Ah to as high as 200Ah, depending on its intended application. The general rule of thumb is to choose a solar panel that can provide 1.5 to 2 times the battery's capacity in watts. [pdf]
