Here’s a simplified way to estimate how long it’d take for the solar panel to charge the battery: 1. Divide solar panel wattage by battery voltage to estimate maximum charge current output by solar charge controller: 2. Multiply current by rule-of-thumb system losses (20%) and charge controller efficiency (PWM: 75%; MPPT: 95%): 3.
Here’s how we calculate the charging time: Charging Time = 600Wh / 56.25Wh per hour = 10.67 hours Here you have it: A single 300W solar panel will fully charge a 12V 50Ah battery in 10 hours and 40 minutes. You can use this 3-step method to calculate the charging time for any battery.
To fully charge a 100-watt solar panel will require 3.7 hours of direct sunshine. Using two 100-watt solar panels, on the other hand, it will only take 1.7 hours to charge. The more solar panels you have, the more electricity you’ll have. It’s important to remember that the type of charge controller you use has an impact on charging time.
Suppose you have a small 5W solar panel and you aim to charge a 12V battery. Considering ideal conditions, it could take about 120 hours to fully charge a 50Ah battery—this emphasizes why panel size matters!
It’s crucial to match the panel size to your 12V battery. For example, a 50Ah (600Wh) 12V battery could be adequately served by a single 150W solar panel, providing about 4-5 hours of direct sunlight a day. Suppose you have a small 5W solar panel and you aim to charge a 12V battery.
Multiply the charge time by the battery’s depth of discharge to estimate how long it’d take to charge the battery at its current level: 6. Add 2 hours to account for the absorption charging stage of most charge controllers: So, in this example, it’d take about 9 hours to charge a 48 volt battery with a 960 watt solar panel.
