Schréder and Sunna Design partner to unlock the potential of solar lighting for your projects.
Cutting-edge solar lighting solutions
Why solar lighting?
Abundant, carbon-neutral energy
Increased energy security
Off-grid lighting reduces vulnerability to energy price fluctuations or network disruption and decreases pressure on energy demand, which benefits the whole community.
Solar energy is the most abundant energy resource on Earth as it constantly receives approximately 173,000TWh of energy from the sun. This is more than 10,000 times the world’s total energy consumption.

Equity among citizens
Low installation and operating costs
The electricity grid is not necessarily available everywhere. However, this is no reason to deprive a part of the population of safety and comfort after dark.
Solar lighting does not require heavy infrastructure work (no underground cabling needed). Its installation and commissioning are more straightforward, with a reduced impact on the environment. And, as it is off the grid, the operating costs are virtually zero.

2 studies to maximise your benefits
Harvest as much solar energy as possible Our experts support you during every stage of your project. We analyse all key criteria to select the solutions that are most suited to your project requirements. To design your efficient solar lighting solution, we take into account numerous factors:
• Site latitude • Orientation of the installation
• Installation direction • Climatic conditions • Potential solar shading
6
Make the best use of every available watt As the amount of available energy is limited by the battery capacity, it is crucial to maximise the use of every lumen that the system is able to generate. A comprehensive lighting study is necessary to maximise energy efficiency while providing the appropriate light distribution for the project. Our lighting study is based on various parameters that influence the choice of light distribution, colour temperature and dimming scenario.
• Applicable norms and standards • Lighting class • Light pollution requirements
• Environment to be lit (width, surface, use, etc.) • Installation layout (height, spacing, overhang, etc.)

A smart lighting package From seafronts to secondary roads, bike paths, parks, commercial facilities and residential streets, solar lighting has become a truly beneficial and sustainable alternative to traditional grid-powered lighting. Schréder EKINOX powered by Sunna Design sets new standards for quick and easy deployment of lighting solutions based on renewable energy.

Dimming scenarios Without detection
LED
At nightfall, the luminaire is switched on at 50% of its maximum output for 3 hours. It then reduces its output to 15% to provide safety lighting throughout the night. At sunrise, the light output returns to 50% for one hour before the luminaires switch off.

With motion detection in places with little nocturnal traffic At nightfall, the luminaire switches on at 50% of its maximum power for 3 hours. It then reduces its power to 12% to ensure safety lighting throughout the night. At sunrise, the light output returns to 50% for one hour before the luminaires switch off. Throughout its operation, the dimming scenario can be overridden by motion detection (car, bike or pedestrian) with the light level rising to 100% for a short period. It maximises visibility to ensure safety and well-being for users. 50% 100% LED 3h 1h 0% 12%
With motion detection in popular places
At nightfall, the luminaire is switched on at 20% of its maximum output for the whole night. When movement is detected (car, bicycle or pedestrian), the lighting level is temporarily increased to 100% to provide maximum safety and comfort to users. This dimming profile allows up to 450 detections per night.

Smart dynamic lighting profile to prevent blackouts As the level of charge in the battery when the luminaire is switched on can vary according to the energy accumulated during the day, it is important to manage energy use intelligently. The on-board electronics divide the night into three parts and adjust the light level as necessary to avoid a blackout situation.

Straightforward implementation Schréder EKINOX powered by Sunna Design is designed for simple on-site deployment and easy adjustment for optimal results.
Standard fixation
The UP solar kits come with post-top mounting for Ø60mm (UP1 and UP2) or Ø76mm (UP4) spigots. Together with its partners, Schréder offers complete solutions, including the appropriate reinforced poles and brackets according to the EN40 calculation and with CE marking.
Solar panels with adjustable tilt angle
The solar panels can be tilted to the most favourable angle (according to the solar study), from 0 to 50°, depending on the selected UP kit. The connection to the luminaire is made by a cable (power and control) equipped with coded connectors to avoid any installation errors.
16
Independent luminaire settings With the luminaire being separate from the solar kit, the adjustment options are independent in order to optimise the photometry and the detection area if the luminaire is equipped with a PIR sensor. Schréder luminaires offer a wide range of tilt settings.
Easy commissioning & diagnostics
With its built-in status indicators, the solar kit enables the initialisation process to be monitored, day and night detection, Bluetooth TM connection status, alarms and sleep mode.
On-site system settings
Although it must be defined when ordering, we can update the dimming profile and override the properties of the PIR sensor on-site, using the Sunna mobile application and a Bluetooth TM connection to the solar kit.
