Brazil's rooftop PV prices rise 7% in the first half as kits get dearer
Serguey Asael Shinder2 min readAverage prices for photovoltaic systems of up to 300 kW in Brazil rose 7% between January and June 2026, according to the "Distributed Energy Solutions" study by consultancy Greener, reported by pv magazine on 26 September. Final prices, which include the equipment kit and installation, ranged from BRL 2.02 per watt for 30 kW and 50 kW systems to BRL 3.62 per watt for 2 kW systems; the smallest systems rose from BRL 3.44 per watt in January.
Equipment drove the increase. The average kit price for a 4 kW system rose 18.3%, from BRL 1.42 to BRL 1.68 per watt, while larger systems saw smaller rises: 8.8% for 50 kW kits and 2.0% for 300 kW. Over the longer run prices are still far below where the market started. A 4 kW residential system cost BRL 7.74 per watt in January 2017 and BRL 2.91 in June 2026.
The market itself slowed. New distributed-generation connections fell 16% year on year in the first half, from 488,000 to 411,000, and the number of new consumer units receiving credits dropped 43%. Residential systems made up 65% of added capacity, against 39% in 2019. Among installers, 80% named residential systems of up to 12 kW as their best-selling category. Only 33% of sales used financing, eight points less than in 2025 and the lowest share in Greener's series.
What it means
Brazil's distributed solar market has become a household market, and households are the buyers most exposed to rising prices. The equipment increase landed hardest on exactly the smallest systems, where the kit is a larger part of the final price, while falling use of financing means more buyers are paying from savings - a combination that leaves demand more sensitive to price.
The drop in new credit recipients, much steeper than the fall in connections, suggests fewer shared or remote-credit arrangements, where one installation credits several consumer units. For installers, the practical conclusion is that price and financing offers matter more than ever in a segment that is now two thirds of the market, and for grid operators the slowdown means less rooftop generation added to distribution networks this year than the previous trend implied.
