The cost of residential photovoltaic systems in Brazil continues to decline. Data from Radar Solfácil, a quarterly indicator tracking solar energy prices in the country, show that the average installation cost fell 7% between the first quarter of 2025 and the first quarter of 2026.

According to the study, the national average price reached BRL 2.45 ($0.47)/W, the standard metric used to measure installed photovoltaic capacity. Costs in several states remained below the national average.

Acre recorded the lowest average residential installation cost, at BRL 2.08/W, followed by Rondônia at BRL 2.17/W and Amazonas at BRL 2.18/W. Other states with below-average prices included Paraíba (BRL 2.25/W), Alagoas (BRL 2.26/W), Mato Grosso (BRL 2.29/W), Roraima (BRL 2.29/W), Mato Grosso do Sul (BRL 2.33/W), Paraná (BRL 2.35/W), and Amapá (BRL 2.36/W).

According to Fabio Carrara, CEO and founder of financing provider Solfácil, falling equipment prices have created a favorable environment for consumers considering investments in distributed solar generation.

“Brazilian consumers are facing a very favorable window for investing in solar energy. We currently see a global scenario of oversupply of raw materials and equipment, particularly in China, which has driven prices down. However, this dynamic is unlikely to last indefinitely. The sector’s natural trend points toward stabilization or even a gradual rise in prices. In practical terms, this may be one of the most affordable times to install solar energy in Brazil,” he said.

Carrara said that oversupply across the global supply chain, particularly in China, has been a key driver of lower photovoltaic system costs. He added that this trend is expected to lose momentum in the coming years, with prices likely to stabilize or gradually increase.
