What is the working principle of solar lighting?
Solar energy into electricity, stored in the battery inside. Battery pack to the lamp (usually LED lights)
Left and right, charge and discharge controller to detect this voltage after the action, the battery on the lamp discharge! The simplest said: solar panels will absorb solar energy and converted into electricity after the power reserve battery for night use.
The use of photovoltaic effect of the principle of solar solar panels solar solar panels to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to 10lux or so, the solar panel open circuit voltage 4.5V
