The provided solar panel charges a supper capacitor on
this WS90. In normal conditions (solar light intensity
over 20klux and lasted longer than 4 hours), the supper
capacitor peak voltage displayed on the battery tile from
your dashboard should be above 3.5v and lower than
5.5v. If it is not overpassing 2.5v, please check the top
part of your WS90, and make sure it is free from dust
coverage. Use a brush to clean up the surface for higher
solar charging efficiency.
