When a solar panel is panel illuminated，it converts light energy into electricity，allowing current to flow from one side to the other. Solar panels are planned according to this Principe. Only when  the solar panels are illuminated by the solar panels can they generate the equivalent of 110 light.

To minimize the reflection of light from solar panels，a thin film is usually covered to prevent light reflection，making the surface of solar panels purple. How can light be converted into electricity？The solar street lamp is mainly composed of four parts：photovoltaic module，light-emitting diode，solar cell and solar street lamp controller.Photovoltaic modules absorb sunlight during the day，converting solar energy into electricity stored in solar cells that discharge at dawn at night.

General sunny days，under the ideal light intensity，full power is only 4 hours，after each charge，can ensure that each charge 5 days more than，and can work normally in the rain for 3 consecutive days.How to control the light switch?At this point,the device controller on the street lamp is activated.
Street lamps can be programmed for light control or time control according to different requirement.It can not only control the charge and discharge time of the battery, but also control the discharge intensity of the battery. In addition, depending on the orientation of the device,the usefulness of solar street lighting will have a considerable impact.Techicians can also plan the equipment according to the specific situation of daily lighting in the place.
