Abre Campo, Minas Gerais, Brazil, situated at -20.2762, -42.4407, offers a promising location for solar PV energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns, with seasonal variation defined more by wet and dry periods than dramatic changes in daylight hours.
Seasonal Solar Production
Solar energy generation in Abre Campo follows a predictable seasonal pattern. Summer months yield the highest energy output at 6.17kWh per day for each kilowatt of installed capacity. Autumn follows with a respectable 5.53kWh/day, while spring produces 5.30kWh/day. Winter experiences the lowest production at 4.67kWh/day per kilowatt installed, though this figure remains substantial compared to many non-tropical locations.
The difference between the highest-producing season (summer) and lowest-producing season (winter) is approximately 1.5kWh/day per kilowatt installed, indicating relatively stable year-round generation potential. This modest seasonal variation makes Abre Campo suitable for consistent solar energy production throughout the year.
Optimal Panel Installation
For fixed solar panel installations at this location, the ideal tilt angle to maximize year-round energy production is 19 degrees facing North. This specific angle optimizes the capture of available sunlight across all seasons, accounting for the location's position south of the equator.
Environmental and Weather Considerations
Several environmental factors could potentially impact solar production in Abre Campo:
- Seasonal rainfall patterns during the wet season may reduce solar efficiency due to cloud cover and direct precipitation on panels
- Dust accumulation, particularly during dry periods, can gradually diminish panel performance
- High humidity levels common in tropical regions may accelerate degradation of system components
- Potential for tropical storms that could physically damage installations
Preventative Measures
To maximize energy production despite these challenges, several preventative measures are recommended:
- Install self-cleaning panels or implement regular cleaning schedules, especially during dry seasons when dust accumulation is highest
- Use corrosion-resistant mounting hardware and weather-sealed junction boxes suitable for tropical conditions
- Consider slight adjustments to the tilt angle during installation to promote natural cleaning from rainfall
- Implement robust mounting systems designed to withstand potential storm conditions
- Ensure proper drainage around ground-mounted systems to prevent water accumulation during heavy rainfall periods
With these considerations addressed, Abre Campo presents a favorable location for solar PV installations with good year-round energy generation potential, particularly during the summer months when output peaks.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 19° North in Abre Campo, Brazil
To maximize your solar PV system's energy output in Abre Campo, Brazil (Lat/Long -20.2762, -42.4407) throughout the year, you should tilt your panels at an angle of 19° 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 Abre Campo, 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 Abre Campo, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 4° North in Summer | 26° North in Autumn | 36° North in Winter | 14° 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 Abre Campo, 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 Abre Campo, 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 Abre Campo, Brazil
The topography around Abre Campo, Brazil presents a diverse landscape characterized by rolling hills, valleys, and mountainous terrain typical of the eastern portion of Minas Gerais state. Located in the Atlantic Forest biome, this region sits within the Mantiqueira mountain range, which forms part of the larger Serra do Mar coastal mountains. The elevation in and around Abre Campo varies significantly, generally ranging from approximately 600 to 1,200 meters above sea level, creating a complex topographical profile. The municipality itself is nestled in a valley surrounded by hills, with several waterways including the Rio Casca and its tributaries cutting through the landscape. These waterways have, over geological time, carved valleys between the elevated areas, resulting in the undulating topography visible today. The terrain gradually rises toward the east and southeast, where more pronounced mountains can be found.
Soil and Vegetation Characteristics
The soil composition in this region typically consists of latosols and argisols, which have developed under the influence of the humid subtropical climate. The natural vegetation is characterized by seasonal semi-deciduous forest, although much of the original Atlantic Forest coverage has been altered by agricultural activities, primarily coffee cultivation and cattle ranching, which have shaped the current landscape. The combination of varying elevations, slopes, and exposure to sunlight creates numerous microclimates throughout the region. Higher elevations generally experience cooler temperatures and potentially different precipitation patterns compared to the valleys.Optimal Areas for Solar PV Development
For large-scale solar photovoltaic (PV) installations, the most suitable areas near Abre Campo would be the flatter plateaus and gentler slopes, particularly those with northern exposure (in the Southern Hemisphere, north-facing slopes receive more direct sunlight). Several promising zones can be identified: The relatively flatter areas to the northwest of Abre Campo, extending toward Raul Soares, offer more consistent topography with fewer steep slopes. These areas balance accessibility with favorable sun exposure conditions. Some of the elevated plateaus to the south and southwest, where the terrain becomes somewhat more uniform before rising into more significant mountains, present opportunities for solar development. These locations benefit from reduced shading from surrounding hills and mountains. The broader valleys along the Rio Casca, particularly where they widen and flatten, could accommodate larger installations, though potential flooding risks would need assessment. Areas where previous agricultural activity has already cleared vegetation might present lower environmental impact options for development, especially in the more gently sloping terrain between Abre Campo and neighboring municipalities like Sericita and Pedra Bonita.Topographical Challenges
The mountainous nature of the region does present certain challenges for large-scale solar development. The frequent occurrence of steep slopes increases installation costs and complexity. Many areas would require significant earthwork to create suitable foundations for solar arrays. The varied topography also creates potential shading issues, where mountains and hills could cast shadows on solar installations during certain parts of the day or year, reducing energy generation efficiency. Careful site selection and array design would be necessary to mitigate these effects. Additionally, the network of rivers and streams that cut through the landscape may limit contiguous areas available for development and potentially introduce flooding concerns in some locations. Despite these challenges, the region's high elevation provides certain advantages for solar energy production, including potentially clearer atmospheric conditions and reduced temperatures compared to lower-lying areas, which can benefit photovoltaic efficiency.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.
