Peak sun hours a day on flat ground. Each dot is one place (the 900 largest). 1 far-off place lies outside the frame.

The sunniest place in Brazil is Catolé do Rocha (Paraíba) with 6.16 peak sun hours a day on flat ground; the least sunny is Paranaguá with 4.01. A 1 kWp array at its best angle makes from 1,264 kWh a year in Paranaguá to 1,803 kWh in Bom Jesus da Lapa — 1,581 kWh on average.

The best year-round tilt runs from 0° in Macapá to 28° in Santa Vitória do Palmar. Off-grid systems are sized for the darkest month and do better steeper, at 22° on average: at 70° that month brings 0.89 kWh per kWp a day in Macapá and 2.79 kWh in Santa Vitória do Palmar.

Questions about solar in Brazil

What is the best angle for solar panels in Brazil?
Facing the equator, between 0° and 28° depending on the place — 16° on average over 2,264 places. Off-grid systems that must get through the darkest month do better steeper, at about 22° on average.
How many peak sun hours does Brazil get?
From 4.0 hours a day in Paranaguá to 6.2 in Catolé do Rocha on flat ground, averaged over the year; 5.2 on average.
How much electricity does 1 kWp of solar panels produce in Brazil?
About 1,581 kWh a year at the best fixed angle on average, from 1,264 kWh in Paranaguá to 1,803 kWh in Bom Jesus da Lapa. These are long-term climate averages; a single year can be several per cent higher or lower.
Where is the sunniest place in Brazil?
Catolé do Rocha (Paraíba) gets the most sun of the 2,264 places: 6.16 peak sun hours a day on flat ground, so 1 kWp there makes about 1,781 kWh a year.
Does Brazil use daylight saving time?
Brazil does not use daylight saving time: the clocks stay the same all year.
How long is the longest day in Brazil?
14 h 23 min in Santa Vitória do Palmar; the shortest day lasts 9 h 56 min in Santa Vitória do Palmar.
