☀️ Peak sun hours in Brazil
Brazil has strong, consistent sun nationwide — roughly 4.5 to 6 peak sun hours. The north-east and central plateau are highest.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| North-East (Bahia, Piauí) | ~5.5 – 6.0 |
| Central-West (Goiás, Brasília) | ~5.2 – 5.7 |
| South-East (São Paulo, Minas) | ~4.8 – 5.4 |
| South (Rio Grande do Sul) | ~4.5 – 5.0 |
| Amazon north | ~4.4 – 4.9 |

⚡ Electricity prices in Brazil
Brazilian electricity tariffs have climbed and vary by distributor and "tariff flag", commonly around R$0.70–R$1.00 per kWh for residential customers. High tariffs plus strong sun make self-generation attractive across most of the country.
💸 Incentives & net metering
Brazil has a mature net-metering scheme (compensação de energia, under ANEEL rules) that credits exported energy against your bill, with credits usable for months. A legal framework (Lei 14.300) is phasing in some charges on the grid-use portion for new systems, so the exact compensation depends on when you connect — check the current ANEEL rules and your distributor.
💰 System cost & payback in Brazil
Local prices are competitive, roughly R$3.50–R$5.00 per watt installed:
| System size | Approx. cost | Suits |
|---|---|---|
| 3 kWp | ~R$11,000 – 16,000 | Typical home |
| 5 kWp | ~R$17,000 – 25,000 | Larger home / higher use |
| 10 kWp | ~R$33,000 – 48,000 | Large home / small business |

💡 Local insight: Brazil
Brazil's combination of strong sun everywhere and a long-standing net-metering scheme gives reliable paybacks, commonly around 4–6 years. The main thing to check is timing: newer rules (Lei 14.300) gradually add a charge on the grid portion of compensated energy, so confirm exactly how your distributor will credit exports before sizing the system.

❓ Frequently asked questions
How many peak sun hours does Brazil get?
About 4.5 to 6. The north-east and central-west are highest (~5.2–6), the south-east around 4.8–5.4, and the far south a little lower.
Is solar worth it in Brazil?
Yes — strong sun plus rising tariffs and net metering give a typical payback of about 4–6 years. It's the biggest solar market in Latin America.
Does Brazil have net metering?
Yes, a mature scheme (compensação de energia under ANEEL). Newer rules (Lei 14.300) add some grid charges for new systems, so confirm current terms with your distributor.
How much does solar cost in Brazil?
Roughly R$3.50–R$5.00 per watt, so about R$11,000–R$16,000 for a 3 kWp system. Get local quotes.
