# Solar-powered signalling – United States

![Solar-powered signalling – United States](https://www.systra.com/wp-content/uploads/2020/09/septa-pennsylvania-solar-signalling-gettyimages2.jpg)

**The Southeastern Pennsylvania Transportation Authority (SEPTA), has selected SYSTRA to install a new alternative photovoltaic power supply for its signalling systems.**

Our American teams are providing engineering and design services to install
solar power supply infrastructures at dedicated locations on four regional lines
of the SEPTA network.

A total of 233 signal locations are involved in the Design Phase, which lasts 6
months, prior to a one-year Construction Phase. Commissioning is expected at the
end of 2021. Our Group is supporting the contractor JJD in the development,
deployment, testing and validation phases prior to commissioning.

This project promises more sustainable mobility for passengers but also enhanced
safety
measures. The solar panels provide an emergency power source, a robust
alternative in extreme weather conditions, allowing the signalling systems to
operate for up to two days during power cuts.

SYSTRA has been involved in Solar PV Engineering projects for several decades at
various levels of responsibility, ranging from project management, engineering,
design, technical assistance during testing, deployment, configuration and
debugging, documentation of all necessary hardware as well as associated
software activities. One of the projects where this know-how has been applied is
the Nagpur Metro in India.
