The first solar airport in the world is located in India, and more specifically in the state of Kerala, which lies to the south of the country. The name of this airport is Cochin International Airport. It is instantly clear that this is a solar powered airport because you can see the reflective solar panels arrayed along the runway.
The solar panels in the airport were installed in 2013, and in August 2015 the airport became completely self sufficient in that it was able to produce all of the energy that it needed as solar energy. Thus, the airport was quickly pronounced a success. Cochin International Airport is also a very popular transport hub: it is currently the seventh busiest airport in all of India. Every week, it handles over a thousand flights.
Making a solar powered airport successful in this way is sometimes referred to as ‘the Cochin model’, after Kerala’s airport. Many international airports wish to emulate it.
