1. A market driven by distributed generation
Brazil's solar growth has been led by distributed generation: rooftop and small ground-mount systems connected to the low- and medium-voltage grid of homes, shops, farms and industries, compensated through net metering. Large utility-scale plants exist too, but they are a different business — sold through auctions and the free market, with direct procurement from manufacturers.
Irradiation is high across the country: the peak sun hours used in system design range from roughly 3.6 to 6.1 kWh/m² per day across Brazilian municipalities, with the best resource in the Northeast and the center of the country.
2. The rules a product must meet
- INMETRO conformity. Photovoltaic modules, grid-tied and off-grid inverters, charge controllers and batteries for PV systems fall under INMETRO's conformity assessment (Ordinance 140/2022). Equipment must be certified and registered before it is sold in Brazil.
- Utility acceptance. To connect a grid-tied system, the installer files an access request with the local utility, including the inverter and module datasheets. Inverters without valid INMETRO registration are refused.
- Grid voltages. Low-voltage services are 127/220 V single-phase or two-phase, or 220/380 V three-phase depending on the region — inverters are specified by phase and output voltage.
- Consumer protection. Warranty and technical support are expected to be handled locally, and documentation in Portuguese is expected by installers and end customers.
The connection procedure and the net-metering rules of Law 14,300/2022 are explained in Grid connection in Brazil.
3. How equipment reaches the installer
The typical route to market is manufacturer → national distributor → integrator. Distributors import or buy locally, keep stock in regional distribution centers, assemble kits (modules, inverter, mounting structure, cables and string box) and extend credit to thousands of small integrators, who design, install and handle the utility approval.
A manufacturer's success in Brazil therefore depends on being in distributors' kit configurators, having local technical support for installers, and keeping datasheets and certificates easy to find — utilities and integrators ask for them on every project.

5. A checklist for entering Brazil
- Certify the product line with INMETRO and keep the registration numbers on the datasheet.
- Publish datasheets with the electrical values installers need for string sizing (Voc, Isc, temperature coefficients) and for the utility request.
- Match inverter models to Brazilian voltages (220 V single-phase, 220/380 V three-phase).
- Choose national distributors and support them with training, local stock of spare parts and warranty service.
- Make the brand visible where installers research equipment — product pages, datasheet libraries and kit configurators.
How Silizium helps
Silizium is the B2B platform where Brazilian distributors publish their catalogs and integrators size systems, compare equipment and request quotes. Listing your product line with complete data and datasheets puts it in front of the professionals who choose the equipment for each project.
