How to calculate the time of solar cell
To charge a solar generator or power station faster, you need to put in more power. You can do this by getting a higher powered AC adapter from the manufacturer. For instance, Goal Zero sells a 600W A. The first step is converting Ah to Wh. Assuming this is a 12V battery, we simply multiply 100Ah x 12V to get 1200Wh. Then we get the usable capacity of the battery. If it's a lithium batte. A 100Ah 12V battery has a capacity of 1,200Wh. The 300W solar panel will produce an average of 70-80% of its rated output, so 210-240W. Let's use an average solar output of 21. Figure out how much power you consume in a day. Find the wattage of each appliance and multiply it by the number of hours you run it each day to get watt-hours. Then add the wat.
