BBC Click's David Reid reports from India's Cochin International Airport, in the southern state of Kerala - the first airport in the world to be powered entirely by solar energy.
Huge power bills prompted the airport to build the 12 megawatt solar plant which has more than 46,000 solar panels.
Silicon carbide can help convert direct current into alternating current with less energy consumption than existing inverters, improving the economics of solar power.
South Australia has once again teamed up with Tesla for a solution to their energy needs, this time to create a network of houses installed with solar power panels and batteries to create a renewable power grid.
Solar power is taking root.
