| This is generally considered the minimum, as it can work fine in [[electrical:solar:output|sunny areas]] with light [[electrical:12v:loads|loads]] and shallow [[electrical:depth_of_discharge|depths of discharge]].((10-20% DoD?)) It may not be enough with heavier use, or in the winter when the sun is low and daylight short. [[electrical:solar:rationing|Power rationing]] may be necessary. | This is generally considered the minimum, as it can work fine in [[electrical:solar:output|sunny areas]] with light [[electrical:12v:loads|loads]] and shallow [[electrical:depth_of_discharge|depths of discharge]].((10-20% DoD?))
