alternatives, which is why we're looking for new options. 1600 kilometers to the north, the city of salvador de bahia. it's home to an important solar stadium project, also built with german support. the converted stadium is latin america's first solar stadium and one of the continent's largest photovoltaic plants. it's also one of the first solar electricity projects to attract the attention of brazil's electricity regulatory agency. >> the stadium is a pilot project. we're going to take a very careful look at it to see how renewable energy might best be supported and utilized. the salvador stadium is also a model for the maracana conversion. in salvador, the weight of the modules was again the biggest challenge. the heavy solar panels were used only on the newly-built side sections. the roof was covered with lightweight solar foils. the state-owned stadium now generates around 600 megawatt hours of power, which supplies nearby government buildings. the photovoltaic modules were built in the us and china. the inverter boxes were built in germany. they convert direct current to alternating current. p
