Very low cost rooftop solar slashes domestic energy cost – Part 2: South American Countries
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.

Chile releases bidding terms for first energy auction including storage
Chile’s CNE has set preliminary terms for the 2026/01 power supply tender, a technology-neutral process that nonetheless favors renewables by excluding high-emission fuels and enabling storage-backed bids. With time-of-day demand blocks and 15-year contracts, the structure is particularly supportive of photovoltaic and hybrid solar-plus-storage projects, especially for daytime and evening peak coverage.
