S4GA is proud to introduce a new solution for the airport industry: Solar CAT I Airfield Ground Lighting. The system is fully compliant with ICAO CAT I requirements, powered entirely by solar energy, and operated via a fail-safe wireless network.
Until now, Category I compliance always meant trenching, cabling, CCRs, and substations. That’s millions in upfront investment and decades of maintenance. Solar CAT I removes all of that. It delivers full ICAO CAT I performance without cables, power stations, or complex infrastructure — powered only by the sun, controlled via a fail-safe wireless network, and continuously monitored by ALCMS.
The system is completely off-grid, which makes it ideal for remote locations or airports with limited technical staff. Because it runs entirely on solar energy, it aligns with sustainability goals and helps airports comply with strict local regulations.
And the numbers speak for themselves:
As a result, S4GA Solar CAT I system can save up to €2.8 million for an airport over 15 years*.
* Calculations are made for a 3,000-meter runway with CAT I approach, 2× PAPI and a small taxiway. For more information about cost savings for your airport, please contact S4GA Team via official channels.
Airports worldwide are facing energy price hikes, blackouts, staff shortages, and tighter sustainability targets. Solar CAT I directly addresses these challenges with a self-sufficient, low-maintenance, zero-emission design. It transforms airfield lighting from a heavy, resource-intensive utility into a sustainable and future-proof solution.
The system is ready for both civil and military airports, regardless of size. It can be installed as a standalone solution where no infrastructure exists, or seamlessly integrated with existing AGL.
S4GA solar lighting is already deployed in 70+ countries, with over 20 million monitored operating hours via ALCMS. Solar CAT I simply takes that proven base and delivers it in a new high-intensity configuration.
The grand premiere of Solar CAT I will take place at Inter Airport Europe 2025. Visit S4GA Booth #B5-1246 to experience how Solar CAT I delivers full ICAO performance in a solar-powered format.
