Fonroche Lighting installed 104 Smartlight Power 365 single arm lights for the A47 interchange of the A16 highway in Peuplingues, France.

1. Solar lighting advantages
The solar lighting permits to get public lighting thanks to photovoltaic energy production. This solution
has several advantages:
- Compared to a streetlight connected to the grid, the installation of a solar streetlight does not
require civil engineering; the installation is therefore much easier, faster and most of all more
economically viable.
- The electricity bill drops to 0 € - System 100% autonomous. The only solar energy produced by
the PV panel is used to power the solar streetlight.
- The installation of ten Fonroche solar streetlights permits to avoid the emission of more than
one ton of CO2 per year.
- Solar lighting poses no risk of electric shock. The system is working in continuous current (24VDC
TBT), so there is no electrical handling necessary for the installation.
- The several components have a long life, with a first maintenance only after ten years, with the
shift of the battery.
- It is possible to perform all the lighting profiles with a solar streetlight (dimming during the night,
extinction of the streetlight...).
- It is possible to communicate with the solar streetlights in order to know remotely and in real
time their operating state and monitor their impact on the project.

2. Case study: A47 Interchange of the A16 highway –
Peuplingues (62) - France
1/ THE NEED
- Highway section lighting
- A47 Interchange on A16 highway securing
- Compliance with the EN13201 standard - ME3a class
2/ THE PROBLEM
- Civil works are too expensive for this interchange.
- The interchange lighting must guarantee the users and transporters safety as well as the safety of
the migrant population in this area.
3/ FONROCHE SOLUTION
- Fonroche Lighting proposed a set of 104 Smartlight Power365 single arm for the whole
interchange.
- The proposed product is sized according to the values measured by the meteorological stations
to the project, based on the last ten years period. All the calculation is then based on the worst
period measured in order to ensure the operation of the streetlight all over the year.
- From the first day of installation, the first streetlights set up have illuminated the road. It took
only 7 days of installation for the interchange to be fully lit.
- The Fonroche solar streetlights are sized to offer an autonomy of 365 nights a year, while being
compliant with the EN 13201 lighting standard. The road interchange is entirely secured by
lighting all year long.
- Over the whole interchange, the Fonroche solar streetlights will permit to avoid the emission of
more than 11 tons of CO2 per year.
4/ PHOTOMETRIC RESULTS
Fonroche Lighting photometric results for the study of the A47 interchange, according to the ME3a class:
Average illuminance Uniformity
15.6 lux 0.53
≥ 15 lux ≥ 0.5
