Solar advertising lighting 20x7m: SOB-4x20W/400W
Solar Lighting System for Large-Format Advertisements and Billboards SOB-4x20W/400W
SOB-4x20W/400W is a professional, autonomous solar lighting system designed for illuminating large advertising surfaces, billboards, advertising boards, large-format structures and container-based advertisements. It is ideal for all locations where access to the power grid is unavailable or where connecting to the grid would be excessively costly.
The system operates entirely on solar energy thanks to two 450 W photovoltaic panels, and it can optionally be expanded with two 400 W wind turbines, ensuring stable operation even during winter and extended periods without sunlight.
Applications of the SOB-4x20W/400W System
This system is most commonly used for illuminating:
- large-format advertisements and billboards up to 20 × 7 m,
- large advertising boards in non-urbanized areas,
- container-based and modular advertising constructions,
- advertising structures mounted on poles or custom support frames,
- billboards along highways and express roads,
- outdoor advertising installations requiring strong illumination for many hours.
Main Features of the System
- 4 LED floodlights 20 W – Polish production, high quality, 5-year warranty, luminous efficacy > 160 lm/W.
- 2 photovoltaic panels 450 W providing stable year-round power supply.
- Option to install 2 wind turbines 400 W – ideal for winter operation.
- Fully autonomous operation without access to the electrical grid.
- Fast installation with no need for utility approvals or electrical project documentation.
- High resistance to weather conditions and vibrations.
- Built-in dusk sensor – automatic switch-on after sunset.
- Controller with multiple programmable operating modes and adjustable light output.
Technical Information
