Bom Sucesso, Minas Gerais, Brazil represents a very good location for year-round solar energy generation, benefiting from its tropical positioning where consistent sunlight is available throughout most of the year, with seasons characterized more by wet and dry periods rather than extreme temperature variations.
Solar Energy Production Performance
The solar energy output at this location shows strong performance across all seasons. Summer delivers the highest production at 6.38kWh per day per kW of installed solar capacity, making it the peak generation period. Spring follows as the second-best season with 5.81kWh/day per kW, while autumn produces 5.53kWh/day per kW. Even during winter, the lowest production period, the location still generates a respectable 4.93kWh/day per kW. This seasonal variation demonstrates that Bom Sucesso maintains relatively consistent solar energy potential throughout the year, with summer and spring being the optimal periods for maximum generation. The difference between the best and worst performing seasons is only about 1.45kWh/day per kW, indicating reliable year-round energy production.Optimal Panel Installation
For fixed panel installations at this location, the ideal angle to tilt solar panels is 20 degrees North to maximize total year-round production. This angle is calculated by analyzing daily solar elevation angles at the latitude, determining optimal panel tilt for each day, and weighting these angles by daily photovoltaic potential using solar irradiance data while accounting for Earth's elliptical orbit.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production at Bom Sucesso and require consideration during installation planning. The tropical climate brings distinct wet and dry seasons, with the wet season potentially creating challenges through increased cloud cover and frequent rainfall. Heavy cloud coverage during rainy periods can significantly reduce solar irradiance reaching the panels, while frequent storms may pose risks to equipment integrity. High humidity levels, common in tropical regions, can affect panel efficiency and may accelerate corrosion of metal components in the solar installation. Additionally, the consistent warm temperatures, while beneficial for year-round operation, can reduce panel efficiency when they become excessively hot.Preventative Measures for Optimal Performance
Several installation strategies can help mitigate these environmental challenges:- Install panels with adequate ventilation spacing underneath to promote air circulation and prevent overheating
- Use corrosion-resistant mounting systems and hardware specifically designed for humid tropical environments
- Implement robust drainage systems to prevent water accumulation around installations
- Choose panels and inverters rated for high humidity and temperature variations
- Design mounting structures to withstand potential storm conditions with appropriate wind load calculations
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Bom Sucesso
Seasonal solar PV output for Latitude: -21.03, Longitude: -44.7958 (Bom Sucesso, Brazil), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 20° North in Bom Sucesso, Brazil
To maximize your solar PV system's energy output in Bom Sucesso, Brazil (Lat/Long -21.03, -44.7958) throughout the year, you should tilt your panels at an angle of 20° 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 Bom Sucesso, 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 Bom Sucesso, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 27° North in Autumn | 36° North in Winter | 15° 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.
Calculate solar panel row spacing in Bom Sucesso, Brazil
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Bom Sucesso, Brazil.
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 Bom Sucesso, Brazil
Topographical Features of Bom Sucesso
The region around Bom Sucesso in Minas Gerais sits within the Brazilian Highlands, characterized by rolling hills and moderate elevation changes typical of the southeastern Brazilian interior. The landscape features a mix of gentle slopes and relatively flat plateaus, with the terrain gradually rising and falling across the area. This part of Minas Gerais displays the classic features of the Mantiqueira mountain system's foothills, though the immediate vicinity of Bom Sucesso itself occupies a more moderate topographical position. The local topography includes several small valleys and ridgelines that create a varied but generally manageable landscape for development. The elevation changes are moderate rather than dramatic, with most slopes falling within reasonable gradients that don't present major obstacles for large-scale infrastructure projects. The region's geological foundation consists primarily of crystalline rocks typical of the Brazilian Shield, providing stable ground conditions.Drainage and Land Use Patterns
The area features a network of small streams and seasonal watercourses that flow through the valleys between the hills. These drainage patterns have created pockets of flatter land along the waterways, while the higher ground between valleys offers more exposed positions with better solar exposure potential. Much of the surrounding countryside consists of pasturelands and agricultural areas, with some remaining patches of Atlantic Forest vegetation on steeper slopes and less accessible areas. The existing land use patterns show a predominance of cattle ranching and mixed farming activities across the gentler terrain. This agricultural landscape has resulted in relatively open areas with minimal tree cover across significant portions of the region, which could be advantageous for solar installations.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be the elevated plateaus and gentle south-facing slopes that characterize much of the region. These areas combine the advantages of good solar exposure with relatively flat or moderately sloped terrain that minimizes construction challenges and reduces shading between panel arrays. The pastoral lands on the broader hilltops and ridge areas present particularly attractive opportunities, as they typically offer unobstructed sky access and are already cleared of vegetation. These elevated positions also tend to have better air circulation, which can help with panel cooling and overall system efficiency. Areas near the valley floors, while flatter, may be less optimal due to potential morning and evening shading from surrounding hills, as well as possible fog formation during certain weather conditions. The middle slopes and plateau areas represent the sweet spot between accessibility, terrain suitability, and solar exposure. The region's relatively stable geological conditions and moderate topography would facilitate the construction and maintenance access required for large solar installations. The existing road network, developed to serve the agricultural community, provides a foundation for the transportation infrastructure needed during construction and ongoing operations.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.
