What is solar panel pavement?

Solar panel pavement consists of layers of solar panels and luminescent glass light guide plates.
The electricity generated by the solar panels during the daytime charges an inner battery and the glass light guide plate can then be illuminated using that electricity during the night. As letters and illustrations can be printed on the glass, it is useful for guidance, security lighting, or other purposes.
The printed letters can still be seen during the daytime even without being illuminated.
The battery storage box can be used to display the current amount of power being generated and other information.

Features of solar panel pavement

  • The solar panel pavement charges during the daytime and illuminates the glass light guide plates using the electricity stored in the battery during the night.
  • Any surplus power can be used to power street lights or sprinkling equipment in planted zones or pavements.
  • As pavements can be illuminated from underneath, it is helpful in crime prevention and increases safety.
