Note: If you already have a solar panel and want to know how long it will take to charge your battery, use our solar battery charge time calculator. .
1. Enter battery Capacity in amp-hours (Ah):For a 100ah battery, enter 100. If the battery capacity is mentioned in watt-hours (Wh), divide Wh by the battery's voltage (v). 2. Enter battery. .
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. 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]
