Solar lighting has several advantages over grid-connected streetlights: - Installation is simpler, faster, and more cost-effective as it doesn't require civil engineering works. - The electricity bill is zero since the solar-powered streetlight is autonomous and uses the solar energy produced by its PV panel. - Installing ten solar streetlights avoids over one ton of CO2 emissions per year compared to grid-connected ones.

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 the 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.
SOLAR LIGHTING
Commercial
parking lot

2. Case study: Mass distribution parking lot - Carcassonne
(11) - France
1/ THE NEED
- Lighting of a public access building (ERP)
- Securing of the staff and customer displacements
- Compliance with EN13201 standard – CE2 Class PRM standard
- Smart programming to optimize the lighting power
according to the night hours
2/ THE PROBLEM
- The parking lot lighting must accentuate the shop entries and must permit customers locate easily the
cart shelters.
- The parking lot can’t be immobilized by works over a long period
- The expected type of lighting must be eco responsible
3/ THE FONROCHE SOLUTION
- Fonroche Lighting has proposed 19 Smartlight Power365 double arm and 11 Smartlight Power365
single arm for the whole parking lot.
- 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 operation of the solar streetlight all over the year.
- From the first day of installation, the first streetlights set up have illuminated the greenway. It only
took one week for all the streetlights to be installed and operate.
- The Fonroche solar streetlights are sized to offer an autonomy of 365 days a year while being
compliant with the EN 13201 lighting standard. The parking lot is totally secured by lighting all along
the year and everyone (including passengers with reduced mobility) can move easily on the parking
lot.
- On the whole parking lot, the installation of the Fonroche solar streetlights will permit to avoid the
emission of more than 3 tons of CO2 per year.
4/ PHOTOMETRIC RESULTS
Fonroche photometric results for the study of the supermarket parking lot, according to the ME3a
lighting class:
Average illuminance Uniformity
20.20 lux 0.64
≥ 20.00 lux ≥ 0.40
