Installing solar power plants at airports is not just a technical challenge — it's also a matter of national security. This is explained by Williman Oliveira, CEO of WSO Solar, the company responsible for implementing photovoltaic plants at airports managed by Zurich Airport Brazil.
According to him, working within the operational area of airports — considered a national security zone — requires authorization from the Federal Police and specific hours of operation. “The standard is more rigorous than usual. It involves strict rules for access, security, and equipment control,” he explains.
In addition to security requirements, the airport environment presents logistical limitations. “Nothing can be left on site. Every item that enters needs to be cataloged when it leaves. You can't move vehicles or materials at any time. Every action needs to be planned because aircraft traffic is constant,” he emphasizes.
WSO Solar began negotiations with Zurich Airport Brazil in 2024 and is currently leading two projects in different phases. first in Macaé (RJ), with 1,4 modules from JA Solar and 1 MWp; and the second in Natal (RN), with 11 modules from Risen and 7,2 MWp.
All systems utilize JA Solar modules and Huawei inverters, endorsed by WEG, which also provided technical support to the company's engineering team. "Being a WEG-accredited integrator was crucial. It guaranteed the bankability and confidence necessary for a project of this complexity," says Oliveira.
With over 1,5 plants installed across the country — including universities, federal institutes, and retail chains — WSO Solar is now expanding its operations to critical infrastructure projects.
“Companies wishing to work on this type of project need solid engineering, very well-defined processes, and a total focus on safety,” he advises. “Each professional needs to have all the required technical training and be prepared to work in an environment of maximum control.”
The airport projects managed by Zurich Airport Brazil are part of a strategy to expand the use of clean energy in the aviation sector, following international standards of sustainability and carbon neutrality.
Lessons for integrators
Ao Canal SolarThe CEO of WSO Solar shared lessons for companies and professionals who want to work on solar energy projects in environments with high technical and regulatory demands, such as airports and large infrastructure projects.
Sound engineering is the starting point: Having a well-structured engineering team is essential to ensure execution meets the technical and safety standards required by regulatory bodies. The professionals involved must receive specific training to work in sensitive environments, focusing on safety protocols and operational control within restricted areas.
Impeccable processes and documentation: In areas classified as national security zones, every piece of equipment, document, and professional must be previously authorized. The planning must ensure complete traceability of materials and activities.
Accreditation with trusted manufacturers: Partnerships with major manufacturers increase the bankability and technical security of the project. WEG's accreditation, for example, was a significant advantage for WSO Energia in terms of reliability and national support with Zurich Airport Brazil.
Planning and daily discipline: Airport projects require synchronization with flight operations and strict adherence to schedules. Every movement must be previously authorized and supervised, leaving no room for improvisation.
Safety and reputation first: Working in critical infrastructure is also a matter of credibility. Commitment to safety and transparency at every stage of the process is what ensures the trust of the client and the authorities involved.
