Campos Altos, Minas Gerais, Brazil presents a very good location for year-round solar energy generation, with consistent performance across all seasons thanks to its tropical positioning. The area benefits from reliable sunlight throughout the year, with energy output ranging from 5.38 kWh per day per kW of installed solar capacity in winter up to 6.21 kWh per day in summer.
Seasonal Performance
Summer delivers the highest solar energy production at 6.21 kWh/day per kW, followed closely by spring at 6.12 kWh/day per kW. These represent the optimal times for solar generation at this location. Autumn maintains strong performance at 5.83 kWh/day per kW, while winter shows the lowest but still respectable output at 5.38 kWh/day per kW. The relatively small variation between seasons - only about 15% difference between the best and worst performing periods - demonstrates the location's reliability for consistent solar energy production throughout the year.Optimal Panel Configuration
For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 19 degrees facing north. This angle has been calculated to optimize total annual solar output by accounting for the sun's position throughout the year and weighting for actual solar irradiance data.Environmental Factors and Mitigation
Several local factors could potentially impact solar energy production in Campos Altos:- Wet season impacts: Extended periods of cloud cover and frequent rainfall during wet seasons can reduce solar irradiance and create debris accumulation on panels
- Dust and agricultural particles: The region's agricultural activity may generate airborne particles that settle on solar panels, reducing their efficiency
- High humidity: Tropical humidity levels can affect equipment performance and accelerate corrosion of components
Preventative Measures
To maximize energy production despite these challenges, several installation strategies should be considered. Regular cleaning schedules become essential, particularly during and after the wet season when panels may accumulate organic debris, mud splashes, and dust. Installing panels with adequate spacing and ventilation helps combat humidity-related issues and allows for better airflow around equipment. Choosing corrosion-resistant mounting systems and electrical components rated for high-humidity environments will extend system lifespan and maintain performance. Additionally, implementing monitoring systems can help identify performance drops quickly, allowing for prompt maintenance interventions. The installation of automated cleaning systems or easily accessible manual cleaning setups can significantly improve long-term energy output. Proper drainage around solar installations prevents water pooling that could create additional humidity issues or attract debris accumulation.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 Campos Altos
Seasonal solar PV output for Latitude: -19.6369, Longitude: -46.1981 (Campos Altos, 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 19° North in Campos Altos, Brazil
To maximize your solar PV system's energy output in Campos Altos, Brazil (Lat/Long -19.6369, -46.1981) 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 Campos Altos, 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 Campos Altos, 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 | 25° North in Autumn | 35° 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 Campos Altos, 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 Campos Altos, 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 Campos Altos, Brazil
Topographical Features of the Campos Altos Region
Campos Altos sits within the Brazilian Highlands, specifically in the western portion of Minas Gerais state. This region is characterized by gently rolling hills and elevated plateaus that form part of the broader Cerrado landscape. The terrain around Campos Altos features moderate elevation changes, with the municipality positioned at approximately 1,000 meters above sea level on a relatively stable plateau system. The topography consists primarily of undulating terrain with gradual slopes rather than steep mountainous features. The landscape is dominated by open grasslands interspersed with gallery forests along watercourses, creating a mosaic pattern typical of the Cerrado biome. These elevated plains extend across much of the surrounding area, providing generally consistent elevation profiles that avoid dramatic elevation changes. Local drainage patterns follow the natural contours of the land, with small streams and seasonal watercourses creating shallow valleys that cut through the plateau surface. The watershed in this area contributes to the broader Paranaíba River system, which flows westward toward the Paraná River basin.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be found on the flatter plateau areas that dominate the landscape around Campos Altos. These elevated plains offer several advantages for solar development, including consistent terrain that minimizes grading requirements and reduces construction complexity. Areas with gentle southern and southeastern slopes would be particularly well-suited for solar arrays, as these orientations can be optimized for maximum solar exposure throughout the year. The open Cerrado landscape provides extensive areas with minimal tree cover, reducing the need for significant vegetation clearing while maintaining environmental considerations. The plateau regions extending northeast and southwest of Campos Altos present the most promising opportunities for large-scale installations. These areas combine favorable topographical conditions with accessibility via existing road networks. The stable geological foundation of the Brazilian Highlands provides solid ground conditions that can support substantial solar infrastructure without significant foundation challenges. Transportation access represents another crucial factor, with flatter terrain facilitating the movement of equipment and materials during construction phases. The elevated position of suitable sites also provides natural drainage advantages, reducing concerns about water accumulation during seasonal rainfall periods that characterize the regional climate patterns.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.
