“Everybody is talking about solar power in the mainstream media outlets and power bills have risen 50% in the past months. If [conditions don't change], we'll reach one million roofs by 2020,” said Carlos Evangelista, founder and senior executive of the Brazilian Association of Distributed Power Generation (ABGD).

Brazil's power regulator Aneel announced this week that 1,074 solar arrays were added, equivalent to 95% of the 1,125 installed across all micro-generation power sources under the country's 2012 net metering rule.
