Solar advertising lighting 12x6m: SOB-2x20W/400W
Solar Lighting System for Billboards SOB-2x20W/400W
SOB-2x20W/400W is a professional solar lighting system designed for illuminating billboards, outdoor advertisements, and large-format display boards in locations remote from the power grid. The system is fully autonomous and operates exclusively on solar energy, making it an economical, reliable, and environmentally friendly solution.
The set is ideal wherever bringing electrical power is costly or impossible, and advertisements need to remain visible throughout the night. Installation does not require any permits, design documentation, or approvals from the power utility.
Illumination of 12 × 6 m advertisements
The SOB-2x20W/400W model is most commonly used for illuminating advertising surfaces measuring 12 × 6 m. The set is equipped with:
- 2 × 20W LED floodlights of Polish production,
- high-efficiency photovoltaic panels,
- a high-capacity battery designed for operation in variable environmental conditions.
The system provides uniform illumination of the entire advertisement for many hours every night.
Complete energy independence
The solar lighting system operates entirely independently of the 230V grid. Energy harvested from the photovoltaic modules is stored in the high-capacity battery, ensuring stable illumination even during cloudy days.
- Autonomous operating mode,
- zero electricity costs,
- maintenance-free operation designed for year-round use.
Weather-resistant batteries
For maximum durability and safety, we recommend installing the batteries:
- underground in a sealed battery box – protection against heat, frost, and theft,
- or above ground – for example on the advertisement structure.
The battery enclosures are waterproof, damage-resistant, and allow easy service access.
High-quality Polish LED floodlights
The set uses professional 20W LED floodlights with the following parameters:
- luminous efficacy >160 lm/W,
- 5-year warranty,
- high resistance to weather conditions IP65/IP66,
- instant start and stable operation.
Applications of the SOB-2x20W/400W system
- Illumination of 12 × 6 m advertisements and smaller,
- billboards along national roads and highways,
- advertisements in undeveloped areas,
- container-based advertisements and free-standing structures,
- information, directional, and communication boards,
- advertising displays in locations without access to electricity.
Custom mounting structures
We offer the possibility of manufacturing custom structures:
- hot-dip galvanized steel structures for billboard mounting,
- free-standing ground-mounted constructions,
- lighting arms adapted to the size of the advertisement,
- PV panel mounting systems installed on top of the billboard.
Main advantages of the SOB-2x20W/400W system
- fully autonomous operation without a 230V grid,
- excellent LED performance ensuring clear advertisement visibility,
- ideal for advertisements in challenging locations,
- very low operating costs,
- long service life and high weather resistance.
The SOB-2x20W/400W solar lighting system is an effective, economical, and environmentally friendly solution for professional billboard illumination in any location.
