The solar panel is fully charged at 30 watts
The formula is: Charging Time (hours) = (Battery Wh × DoD) ÷ (Panel W × Efficiency) Let's break it down in plain English: Battery Wh is your battery energy in watt-hours. DoD is how much of the battery you want to recharge. Panel W is your solar panel's power rating. Adjust for sunlight hours to find daily charging duration. There are many different variables that will affect the ultimate result, such as the size of the battery, the efficiency of the panel, the number of hours in a day of sunlight, etc. By. . 30w solar panel can produce enough power to run a small portable fan, Charge cell phones, laptops, and other small appliances in the range of 25w. Efficiency is the real-world. .
