 This is generally considered the minimum, as it can work fine in [[electrical:solar:output|sunny areas]] with light [[electrical:12v:loads|loads]].  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]].  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.
