Equipment costs fell 17% while overall consumer-facing prices declined approximately 9% throughout 2025, according to separate analysis from Greener’s Distributed Energy Solutions study. The cost of a standard 4 kilowatt-peak residential system without battery storage ranges from BRL 10,000 to BRL 12,500, while hybrid systems incorporating 5 kilowatt-hour lithium batteries cost BRL 24,000 to BRL 30,000. Installation labor represents 25% to 35% of total project costs, typically BRL 4,000 to BRL 6,000.
The pricing improvements contrast sharply with market performance indicators. Total solar capacity additions in Brazil fell 29% to 10.6 gigawatts in 2025, down from 15 gigawatts in 2024, according to ABSOLAR. Investment declined 40% to BRL 32.9 billion. The sector cited generation curtailment, grid connection difficulties and dollar appreciation as primary obstacles. Distributed generation accounted for 7.8 gigawatts of 2025 additions while centralized generation contributed 2.8 gigawatts.
High interest rates throughout 2025 reduced financing penetration to 41% of sales, affecting price-sensitive consumers. Despite lower equipment costs, industry participants anticipate upward price pressure in 2026 from increased logistics costs, dollar appreciation and fiscal changes including the expiration of tax benefits for photovoltaic modules. The market intelligence firm Mordor Intelligence projects Brazilian solar capacity will grow from 75.87 gigawatts in 2026 to 140.25 gigawatts by 2031, representing a 13.07% compound annual growth rate.
