Pirapora do Bom Jesus, Brazil presents a reasonably good location for year-round solar energy generation, though it experiences notable seasonal variations in output. Located in the tropics at coordinates -23.372, -46.978, this area benefits from consistent sunlight throughout most of the year, with seasons typically characterized by wet and dry periods rather than dramatic temperature changes.
Seasonal Solar Performance
The solar energy output at this location varies significantly across the seasons. Summer delivers the highest production at 6.06 kWh per day per kW of installed solar capacity, making it the ideal time for solar generation. Spring follows as the second-best season with 5.33 kWh/day per kW, while autumn produces 5.06 kWh/day per kW. Winter represents the least productive period, generating 4.16 kWh/day per kW of installed capacity. For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 22 degrees facing north. This optimal angle is calculated by analyzing daily solar elevation angles at this latitude, determining daily optimal panel positioning, and weighting these angles using solar irradiance data while accounting for Earth's elliptical orbit.Environmental and Weather Challenges
Several local factors could significantly impact solar energy production in Pirapora do Bom Jesus:- Heavy rainfall during wet seasons can reduce solar irradiance and create cloud cover that diminishes energy output
- High humidity levels typical of tropical climates can lead to moisture accumulation on panels
- Dust and particulate matter from surrounding areas can accumulate on panel surfaces
- Vegetation growth in the humid tropical environment may create shading issues
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be implemented:- Install panels with adequate spacing and ventilation to prevent moisture buildup and allow for proper air circulation
- Implement regular cleaning schedules, particularly during and after wet seasons when dust and debris accumulation is highest
- Design mounting systems that facilitate easy access for maintenance and cleaning
- Conduct thorough site surveys to identify and remove potential shading from vegetation before installation
- Consider anti-reflective coatings that can help maintain efficiency in high-humidity conditions
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 22° North in Pirapora Do Bom Jesus, Brazil
To maximize your solar PV system's energy output in Pirapora Do Bom Jesus, Brazil (Lat/Long -23.372, -46.978) throughout the year, you should tilt your panels at an angle of 22° North for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Pirapora Do Bom Jesus, Brazil
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Pirapora Do Bom Jesus, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° North in Summer | 29° North in Autumn | 39° North in Winter | 17° North in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Pirapora Do Bom Jesus, Brazil
Topographical Features of Pirapora do Bom Jesus Region
The area surrounding Pirapora do Bom Jesus sits within the broader São Paulo metropolitan region, characterized by gently rolling hills and undulating terrain typical of the Brazilian Highlands. This landscape forms part of the Planalto Atlântico, where elevations generally range from 700 to 900 meters above sea level. The topography consists of rounded hills separated by shallow valleys, creating a moderately dissected terrain that slopes gradually toward the Tietê River system. The region's geological foundation comprises primarily crystalline rocks from the Precambrian era, overlain in places by sedimentary deposits. This underlying structure has created a landscape of moderate relief, with hillcrests rising 50 to 150 meters above the surrounding valley floors. The terrain exhibits a mix of convex slopes and broader plateau-like surfaces, interspersed with narrow valleys where streams have carved their way through the landscape over millennia. Local drainage patterns follow the natural topographical contours, with numerous small tributaries feeding into larger waterways that eventually connect to the Tietê River. These watercourses have created a dendritic drainage network, resulting in a landscape punctuated by stream valleys and interfluves. The soil composition varies across the region, with deeper, more fertile soils typically found in valley bottoms and thinner soils on steeper slopes and hilltops.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations in this region would be the broader hilltops and plateau surfaces that offer relatively flat to gently sloping terrain. These elevated areas provide several advantages for solar development, including reduced risk of flooding, good drainage characteristics, and typically fewer competing land uses compared to the more fertile valley bottoms. The southwestern and southern exposures of the larger hills present particularly favorable conditions for solar panel installation. These areas benefit from optimal sun angles throughout the day while offering sufficient space for large arrays. The moderate slopes found on these exposures, typically ranging from 2 to 8 degrees, are ideal for solar installations as they facilitate natural drainage while maintaining good solar exposure angles. Areas with existing cleared land or pasturelands on the higher elevations would be most practical for development, as they require minimal site preparation compared to forested slopes. The region's network of rural roads provides reasonable access to many of these elevated sites, though some infrastructure development might be necessary for the largest installations. The broader valley floors, while offering flat terrain, may be less suitable due to their agricultural value and potential for seasonal flooding. However, some of the wider valley areas with less productive soils could serve as secondary options for solar development, particularly where they connect to existing electrical infrastructure.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Brazil?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power.
