Through industry-wide implementations and S4GA projects, we see a clear shift as airports embrace solar airfield lighting and eliminate conventional electrical infrastructure. Indeed, solar-powered systems offer numerous advantages, including advanced LED technology, rapid installation, and simplified design, motivating the industry to change its approach to airfield illumination.
However, the main driving force in adopting solar AGL is unmistakable – tremendous savings on expenses across the board – from initial deployment and ongoing maintenance to operational expenses.
Traditional AGL infrastructure is often complex, involving extensive digging, complicated cable networks, and backup power systems. These elements usually make up a large part of an airport’s capital expenditure.
Solar AGL systems, through their independent design, eliminate these traditional requirements. S4GA installations demonstrate that utilizing solar-powered components instead of conventional infrastructure such as electrical wiring, CCRs, backup power generators, and civil works, typically saves around 50% in initial deployment costs.
The maintenance burden of conventional AGL systems extends far beyond routine inspections. Traditional systems demand specialized technical expertise, sophisticated diagnostic equipment, and frequent cable network interventions, costing airports 9-12% of their initial investment annually.
In contrast, solar AGL maintenance protocols are simple. The system architecture requires only periodic battery replacement and standard visual assessments. This takes up only 2-3% of the initial investment annually, allowing the airport to save up to 90% just on maintenance.
Solar AGL systems run entirely on renewable energy, eliminating electricity costs. This is particularly valuable for regions with high electricity costs, such as Sub-Saharan Africa, South Asia, East Asia & Pacific region. Airports relying on solar AGL can save 100% on electricity costs for airfield lighting operations when the systems are properly implemented.
Solar-powered airfield lighting has proven itself as a cost-effective solution at airports worldwide. These systems have shown real, measurable financial benefits in every key area of performance, with the entire system paying off completely within 5-10 years. The advantages are compelling: 50% savings on installation, 90% reduction in maintenance costs, and complete elimination of electricity expenses.
Solar lighting systems deserve a closer look for airfield operators contemplating infrastructure upgrades. They offer something rare: immediate cost savings combined with long-term environmental benefits, backed by a growing number of successful installations worldwide.
