Solar lighting utilizes photovoltaic energy for public illumination, offering advantages such as no electrical bills, autonomy, and reduced CO2 emissions. A case study for a bus shelter in France showcases how a solar streetlight enhances user safety while complying with lighting standards and minimizes light pollution. The system is designed for long-term durability and can be remotely monitored for efficiency.

1. Benefits of solar lighting
Solar lighting permits to get public lighting thanks to photovoltaic energy production. This lighting
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 simpler, faster and most of
all viable economically.
- 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 electrical shock. The system is working in continuous current
(24VDC TBT), so there is no electrical handling necessary for installation.
- The several components have a long service 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.

Bus shelter

2. Case study: Bus shelter - Brix (50) - France
1/ THE NEED
- Securing of an isolated bus shelter
- Lighting of the bus shelter
- Compliance with the EN13201 standard
2/ THE PROBLEM
- Improve the user’s safety.
- Smart programming to avoid the luminous pollution and provide comfort to the inhabitants.
- Prevent the constraint of connection to the electrical grid
3/ THE FONROCHE SOLUTION
- Fonroche Lighting has proposed 1 Smartlight Power365 single arm to illuminate the bus shelter.
- The offered product is sized according to values measured by the nearest 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 solar streetlight all over the year.
- From the first day of installation, the solar streetlight has illuminated the bus shelter. One day of
installation has been enough for the streetlight to be completely installed and efficient.
- The Fonroche Lighting solar streetlights are sized to offer an autonomy of 365 days a year while being
compliant with the EN 13201 European lighting standard. The bus shelter is now totally secured by
the lighting all year long.
- The smart programming permits to reduce significantly the streetlight lighting power once the bus
tour is over. The comfort of the inhabitants in the surroundings is preserved.
