Solar Battery / Solar Battery

Solar Battery

Nowadays, there is an increasing rate in the dependence on energy.
Therefore, the environmental friendly energy carrier plays an important role.
This design hereby presents a solar battery which imitates the roll-film’s
retracing mode for storage with a power-accumulating plate rolling solar power
inside it. When out of power, pull out the above mentioned power-accumulating
plate in the sun for regaining the power. Once it is full charged, just a gentle draw
can fulfill the automatic receiving of the plate roll.
