As photovoltaics continues getting cheaper, an increasing number of countries are adapting their regulatory frameworks to facilitate its integration into electricity markets. Brazil is currently adding more than 1 GW of new PV capacity each month, with the majority coming from small-scale, distributed rooftop installations. In this regard, Brazil stands out as an exception in South America. The country's rapid solar expansion is not primarily driven by lower solar module prices compared with neighboring Latin American countries. Instead, it is largely the result of high conventional electricity prices, accessible financing, supportive regulations, tax incentives, and the scale of its energy market.
