Grid Complementary Solar Led Street Lights

Grid Complementary Solar Led Street Lights

by OiSCAPE / Wednesday, 20 May 2020 / Published in Technology

We will introduce a kind of solar street light with grid power complementary. Its main function is to switch to grid power when solar power is insufficient. In this way, when experiencing a long rainy season, or in areas with insufficient light at high latitudes, solar street lights can function well without the lights shutdown.

The difference between grid complementary solar street lights and traditional solar street lights is that grid complementary solar street lights need to connect a set of mains cables to the grid, and need a transformer to convert grid AC electricity to suitable DC electricity.

The technology used by the grid power complementary solar street lights is not a traditional grid-tied technology. It does not upload solar power to the grid. Its grid connection means that when it encounters a long rainy day and the solar power supply is insufficient, it switches to the grid power supply.

Main advantages of grid complementary solar street lights are:

  • The light source can be used for very larger power.
  • Less affected by the weather and environment.
  • Low requirements for batteries and battery box.

Main disadvantages:

  • Cables need to be laid, which is troublesome to install.
  • Need to configure additional power driver and constant current source.

Grid power complementary solar led street lights, or we may also called it on-grid solar led street lights can solve the problem of insufficient solar light in high latitude areas and the long rainy season in certain areas. Compared with the ordinary solar street lamp, it solves the problem of light-off caused by rainy days and insufficient light. Both systems have their own advantages and disadvantages. And such technology could be also used in solar flood light, solar parking lot light, integrated solar street light.

      Hi Eng. Ibrahim Masudi Nzowah, a solar battery use LiFePO4 battery which has more than 2000cycles at 90% SOC, 25°C, 80% capacity remain. But for solar street light, it is not suitable as energy storge for 1MW because the lights are spreads out in a long road.
