Petra's Smart City Solution™ converts streetlights into intelligent pole-mounted devices that combine distributed solar power with smart lighting and communications. This network forms the backbone for Smart City applications, improving public safety while yielding strong project economics and maximizing value.

Energy Efficient, Sustainable, Net Zero Energy Streetlight Networks

  • Reduces municipal streetlighting costs up to 70 percent using smart controls
  • Each solar generator powers four streetlights. A network of 10,000 poles eliminates 7 million pounds of carbon emissions a year, the equivalent of taking 790 vehicles off the road

Self-Fund Smart City Projects

  • Establishes a distributed data and communications network for enhanced security and extended service at little to no cost
  • Allows cities to self-fund Smart City technologies including surveillance, public and private Wi-Fi, electric vehicle charging, emergency response and grid performance monitoring

Strengthen Municipal Resilience

  • Introduces grid-independent communications, a critical asset for responding to emergencies such as earthquakes and extreme weather events
  • Robust and resilient communications and lighting remain active during grid disturbances

Enhance Public Safety

  • Provides public safety personnel with access to real-time information to enhance the quality and speed of their response
  • Customize cameras, sensors and other metering and communication devices to meet your needs
