Background

Green Frog Systems was contracted to light up a very dark, flood prone public underpass with solar power. It was required that the installation:

  • Was totally off-grid, the location had no access to mains power.
  • Would provide adequate lighting levels to ensure public safety when using the pedestrian underpass,
  • Had vandal resistant fixtures that were flood proof. Due to the location of the underpass the possibility for acts of vandalism and deliberate damage was quite high.
  • Was a low voltage system (would not require an electrician to install)

Solution

  • Green Frog Systems were able to re-imaging the capabilities of the flagship GFS-200 Solar Street Light unit into a pole-top solar harvesting and energy storage system. This meant that the system could feed solar power from the 600W solar panels on the GFS-600-ESS (custom upgraded configuration of the GFS-400-ESS) on each solar storage system on either side of the bridge into the two quad-battery energy storage systems. The lighting fixtures used were both flood and vandal resistant, using specifically designed DEFENDER-26 LED tubes on cable feeds.

Outcome

  • The customer was pleased with the outcome of the project and planned to implement similar systems for various applications such as irrigation controllers around the district. The system keeps overall energy consumption down without compromising on public safety, and ensures that the overall illumination of underpasses, bridges and tunnels is reliable. Even during power outages.
