Juramento, Minas Gerais, Brazil represents an excellent location for year-round solar photovoltaic energy generation. Positioned in the tropics at coordinates -16.8347, -43.585, this area benefits from consistent sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than dramatic changes in daylight hours.
Solar Energy Production Potential
The solar energy output data for Juramento demonstrates strong and consistent performance across all seasons. Spring offers the highest production at 6.37 kWh per day per kW of installed solar capacity, closely followed by summer at 6.29 kWh per day. Even during the lowest production period in winter, the location still generates a respectable 5.57 kWh per day per kW, while autumn produces 6.06 kWh per day. This relatively small seasonal variation of less than 15% between the best and worst performing seasons indicates that Juramento is highly suitable for solar installations. The consistently high output levels throughout the year make it an ideal location for both residential and commercial solar projects.Optimal Installation Configuration
For fixed panel installations at this location, the ideal angle to tilt solar panels is 16 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 Challenges
Several environmental factors could potentially impact solar production in Juramento and require consideration during installation planning:- Seasonal rainfall patterns: The tropical wet season can bring heavy rains and increased cloud cover, which may temporarily reduce solar output during certain months
- Dust and debris accumulation: Dry seasons may lead to dust buildup on panels, reducing their efficiency
- High humidity levels: Tropical climates often feature elevated humidity, which can affect equipment longevity and performance
- Intense UV exposure: Strong tropical sunlight, while beneficial for energy production, can accelerate wear on solar panel materials and mounting systems
Preventative Measures for Optimal Performance
To ensure maximum energy production and system longevity in Juramento's tropical environment, several preventative measures should be implemented:- Regular cleaning schedules: Establish routine panel cleaning, particularly during dry seasons when dust accumulation is highest
- Quality mounting systems: Use corrosion-resistant materials designed for high-humidity tropical environments
- Proper ventilation: Ensure adequate airflow around panels to prevent overheating and moisture buildup
- Weather-resistant components: Select inverters, wiring, and other electrical components specifically rated for tropical conditions
- Drainage considerations: Design installations with proper water runoff to prevent standing water during heavy rains
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 16° North in Juramento, Brazil
To maximize your solar PV system's energy output in Juramento, Brazil (Lat/Long -16.8347, -43.585) throughout the year, you should tilt your panels at an angle of 16° 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 Juramento, 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 Juramento, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° North in Summer | 23° North in Autumn | 32° North in Winter | 11° 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 Juramento, 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 Juramento, 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 Juramento, Brazil
Juramento is located in the northern region of Minas Gerais state, Brazil, situated within a landscape characterized by gently rolling hills and broad valleys typical of the Brazilian Cerrado biome. The terrain around this municipality features relatively modest elevation changes, with the area sitting at approximately 800 meters above sea level on a plateau that forms part of the broader Central Brazilian Plateau system.
The topography consists primarily of undulating terrain with gradual slopes and extensive flat to gently sloping areas. This region represents a transition zone between the more mountainous areas to the south and east and the flatter expanses that extend northward toward the São Francisco River valley. The landscape is punctuated by occasional low hills and ridges, but these rarely present significant obstacles to development or create substantial shadowing effects.
The local drainage system includes several small streams and seasonal watercourses that flow generally northward toward the São Francisco River basin. These waterways have carved shallow valleys into the landscape, creating a pattern of low ridges and gentle depressions across the region. The soil composition consists largely of well-drained lateritic soils typical of the Cerrado, which provide stable foundations for construction while allowing good water infiltration.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Juramento would be the extensive flat to gently sloping areas that dominate the landscape to the north and west of the municipal center. These areas offer several advantages including minimal grading requirements, reduced construction costs, and optimal panel positioning without significant terrain-related shading issues.
The broad plateau areas extending toward the São Francisco River valley present particularly attractive opportunities for solar development. These locations combine favorable topographic conditions with good accessibility via existing rural road networks. The gentle slopes in these areas, typically ranging from flat to approximately 5-degree inclines, are ideal for solar panel arrays as they allow for efficient water drainage while maintaining optimal solar exposure angles.
Areas to the southwest of Juramento also show strong potential, where the terrain opens into wider valleys with consistent southern exposure on north-facing slopes. These locations benefit from stable geological conditions and are generally free from the seasonal flooding that can affect lower-lying areas near major watercourses.
The elevated plateau areas offer additional advantages including good natural drainage, reduced risk of flooding during the rainy season, and typically stronger and more consistent wind patterns that help with panel cooling. The stable geological foundation provided by the underlying crystalline rocks of the Brazilian Shield ensures long-term structural integrity for large solar installations.
When selecting specific sites, the most favorable locations would avoid the immediate vicinity of the few higher ridgelines that could create morning or evening shadows, while taking advantage of the extensive open areas that characterize this region of the Cerrado. The relatively sparse vegetation and existing agricultural use of much of the land also facilitates easier site preparation and development compared to more densely forested areas.
