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. .
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 100 watt solar panel can charge a 35ah battery in 5-6 hours. The charge time will take longer if there is not nough sunlight available. The formula is sun hours x 100W / battery volt = battery charge capacity If you live in Arizona you can get up to 7-8 hours of sunlight during the summer. [pdf]
