On a mostly sunny day in spring or summer, it takes around 5 days2. On a mostly sunny day in fall or winter, it takes around 10 days As you can see, we haven’t given an example of how long it takes to recharge on mostly cloudy days. This is because, unfortunately, solar charging is really not effective enough in these conditions.At Xtorm we use the high efficiency SunPower solar cells to provide as much power as possible from a small surface area. Are the charging times listed above not as fast as you would like? Don’t worry, at Xtorm we have solar chargers and panels in all sizes.
