Free market, curtailment, and storage reshaping Brazilian solar sector
Brazil’s solar sector is entering a new phase marked by curtailment, grid constraints, and regulatory shifts, with growth increasingly tied to new business models and market dynamics. Industry leaders say storage will be central to this transition, enabling system integration, mitigating risks, and unlocking future demand.
New PV inverter efficiency metric reflects local solar conditions
Researchers in Brazil have developed a weighted PV inverter efficiency methodology that accounts for country-specific solar irradiance and operating conditions. The approach is designed to address the limitations of international metrics by incorporating variables such as input voltage and maximum power point tracking (MPPT) performance.

Brazil curtails 20% of solar and wind output in 2025, with losses at $1.2 billion
Brazil curtailed about one-fifth of its solar and wind generation in 2025, wasting an estimated BRL 6.5 billion ($1.23 billion), as grid constraints and demand mismatches pushed the power system close to operational safety limits on 16 days, according to a report from Volt Robotics.
Brazil eyes April 2026 for first battery storage auction
A 20-day public consultation is anticipated to open in November to define the guidelines for the auction, which aims to contract 2 GW of battery energy storage systems (BESS). The initiative could unlock around R$10 billion ($1.85 billion) in investments.
