The working principle of solar road studs

Solar panels of solar road studs absorb sunlight during the day and turn the solar energy into electricity and stored in the storage devices (batteries or capacitors). In the evening, the electricity in the storage device can be automatically converted into light energy (controlled by the photoelectric switch), through the LED light to show the path outline and guide the sight of drivers.

Solar road studs can be divided into embedded type and raised type in accordance with different installation position.
The former is generally used in the center line and the latter is commonly used in the edge line. This is because the solar road studs installed in the center line have particularly higher requirements on the compression resistance. To solve this problem, the solar road studs have to be buried into the ground with only around 5mm above the ground. While the requirements of solar road studs used on the edge line on pressure performance is not particularly high, thus they can still work effectively protruding the ground.

Solar road studs can be divided into capacitance and battery type in accordance with different energy storage elements.

The service life of the former can be up to five to seven years, and the service life of the latter is generally ranging from one to three years.
Because embedded type solar road studs would cause serious damage to the pavement, and the cost of capacitance type solar road studs is too high, so the most used solar road studs is the raised type battery solar road studs.
