Work is scheduled to begin this month on Latin America's first solar-powered soccer stadium.
The solar array will be installed on the canopy covering the grandstands at the at the Pituacu Stadium in Brazil.
It is part of an effort to outfit all the 2014 World Cup venues with solar power, reports the International Business Times.
The installation of the solar panels is expected to be completed by December.
A 3-megawatt solar farm was built last year at the NASCAR Pocono raceway in Pennsylvania. It was the largest solar sports stadium in the world, according to Energy Matters, at more than double the size of the second-largest solar-powered stadium, located in Taiwan.
The stadium in Brazil will put out 403 kilowatts at its peak power voltage.
The project is a joint venture between German photovoltaics company Gehrlicher Solar and Brazilian environmental technology group Ecoluz Participacoes.
