Advantages of Solar Lighting

Quality without compromise endorsed by ICAO and the others

Combination of quality and affordable price is what majory of our customers are communicating when looking for good product. Price of different products is relatively easy to compare. However interpretation of the word “quality” requires more time. We like to ask our customers about definition of “quality” and which criteria do they use to understand whether or not they are offered with quality product. We found out that concept of quality is perceptual and subjective atrribute that can be understood differently by different people. When choosing airfield lighting airports operators would look at how this product compares to competitors in the market place. Maintenance personnel would measure quality in the degree that product is reliable and low-maintenance. For pilot the only thing that matters is high visibility range and correct chromaticity (colour) of lights.

S4GA focuses on every one of those critical elements to make sure that each lighting unit is ICAO-compliant, fault-free and can perform its duty for at least 12-15 years.

How do we achieve that?

S4GA Solar AGL is built of highly reliable and long-lasting components. Each and every lighting unit has to go through rigorous testing that is performed manually using the precise testing equipment. Optical characteristics of the unit are confirmed by a third-party accredited laboratory in order to make sure compliance with ICAO requirements.

Solar Airfield Ground Lighting has multiple benefits in terms of affordability, maintenance and reliability. S-AGL is 3-5x time cheaper than conventional (wired/MAINS) lighting. Als, many features of S-AGL makes it significantly more reliable and maintenance-friendly than conventional AGL.

system comparison – For 2000 m runway and 2000 m parallel taxiway includes:


Conventional airfield ground lighting

  1. Lighting fixture x 185
  2. Isolating transformer x 185
  3. Primary cable 34 km
  4. Constant current regulator (CCR) x 5
  5. Switch
  6. Optical fiber
  7. Airfield lighting interface

Solar airfield ground lighting

  1. SP-401 lighting unit x 185
  2. UR-201 Control & Monitoring Interface x 1
  3. Wireless mesh network (868 MHz)
It is so simple.
So check why it is so reliable too.

How is SOLAR lighting different from conventional


Conventional airfield ground lighting

  1. Lighting circuit has to be energized with external source of power
  2. Constant Current Regulator is used to regulate electrical current in the primary circuit
  3. Controlled current flows hundreds of meters towards lighting fixtures
  4. Before getting to lighting fixture electricity is again adopted by Isolating Transformer
  5. Lighting fixture receives power from the electrical circuit

Solar airfield ground lighting

  1. Solar energy generated by the sun
  2. Solar panel converts solar energy into electrical energy
  3. Electrical energy gets into the lighting unit via charging port
  4. In-built micro-controller manages electrical energy and charges battery when needed
  5. Battery stores electrical energy
  6. If light is activated micro-controller uses electrical energy stored in the battery to power LED
  7. Lighting unit is controlled and monitored wirelessly
