Solar powered light box is a relatively simple concept. In a basic
way, the system operates like a bank account. Withdrawals from the
battery to power the light source must be compensated for by
commensurate deposits of energy from the solar panels. As long as
the system is designed so deposits exceed withdrawals on an average
daily basis, the battery remains charged and light source is
The key to solar outdoor light box is the solar power pack, which
houses photovoltaic solar panels, a proprietary microprocessor
control system, and batteries. This is attached to specifically
designed lights having super reflectivity and high energy ballasts.
- The sun provides a direct source of energy to the solar panel.
- The battery is recharged during the day by direct-current (DC)
electricity produced by the solar panel.
- The light source is powered by the battery each night.
- Electronic controls are used between the battery, light source and
solar panels to protect the battery from overcharge and discharge,
and to control the timing and operation of the light.
