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 volts (V): Is this a 12, 24, or 48-volt. .
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. .
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. A 100ah 48V battery holds 4800 watts, so you need solar panels that can produce at least that amount. 3 x 350W solar panels can charge the battery in 5 hours. Assuming each panel produces 350 watts an hour, that is 5250 watts total in a day. [pdf]
