Bom Jesus do Tocantins, Brazil presents an excellent location for year-round solar photovoltaic energy generation. Located in the tropics at coordinates -4.9918, -48.8237, this area benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods rather than dramatic temperature variations.
Solar Energy Production Potential
The solar energy output data for Bom Jesus do Tocantins shows remarkably consistent performance across all seasons. Winter emerges as the peak production period, generating 5.94 kWh per day per kW of installed solar capacity. Spring and autumn follow closely with 5.67 kWh/day and 5.64 kWh/day respectively, while summer produces 5.11 kWh/day per kW. This seasonal pattern is typical for locations in the Southern Hemisphere tropics, where winter months often provide clearer skies and optimal sun angles. The relatively small variation between seasons (less than 17% difference between highest and lowest production) makes this location highly reliable for consistent solar energy generation throughout the year. For fixed panel installations at this location, the ideal tilt angle to maximize total year-round solar production is 6 degrees facing North. This shallow angle reflects the location's proximity to the equator, where the sun passes nearly overhead throughout much of the year.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production in Bom Jesus do Tocantins:- Wet season rainfall and cloud cover: Heavy rains and increased cloud coverage during wet months can reduce solar irradiance
- High humidity levels: Tropical humidity can lead to moisture-related equipment issues and reduced panel efficiency
- Dust and debris accumulation: Dry season conditions can cause dust buildup on solar panels
- Extreme heat: High temperatures can reduce photovoltaic panel efficiency
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Proper drainage systems: Install panels with adequate spacing and drainage to prevent water accumulation during heavy rains
- Regular cleaning schedules: Implement routine panel cleaning, particularly during dry seasons when dust accumulation is highest
- Ventilation design: Ensure proper airflow around panels to reduce heat buildup and improve efficiency
- Quality mounting systems: Use corrosion-resistant materials suitable for high-humidity tropical environments
- Monitoring systems: Install performance monitoring to quickly identify and address any weather-related efficiency losses
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 Jesus Do Tocantins
Seasonal solar PV output for Latitude: -4.9918, Longitude: -48.8237 (Bom Jesus Do Tocantins, 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 6° North in Bom Jesus Do Tocantins, Brazil
To maximize your solar PV system's energy output in Bom Jesus Do Tocantins, Brazil (Lat/Long -4.9918, -48.8237) throughout the year, you should tilt your panels at an angle of 6° 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 Jesus Do Tocantins, 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 Jesus Do Tocantins, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° South in Summer | 12° North in Autumn | 21° North in Winter | 1° South 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 Bom Jesus Do Tocantins, Brazil
Topographical Features of Bom Jesus do Tocantins
Bom Jesus do Tocantins sits within the expansive Brazilian Highlands region of central Brazil, characterized by relatively gentle rolling terrain with moderate elevation changes. The landscape around this municipality features a mix of elevated plateaus, shallow valleys, and undulating hills typical of the cerrado savanna ecosystem that dominates this part of Tocantins state.
The elevation in the immediate vicinity ranges from approximately 200 to 400 meters above sea level, with the terrain gradually rising toward the southeast where it meets the foothills of the Brazilian Shield. Most of the surrounding countryside consists of broad, gently sloping surfaces interrupted by occasional low ridges and shallow depressions that channel seasonal water flow.
The region experiences distinct wet and dry seasons, with the topography reflecting this climate pattern through sparse tree cover and extensive grasslands. Rolling hills covered in cerrado vegetation create a landscape of moderate relief, where steep slopes are uncommon and most areas maintain gradual gradients suitable for various land uses.
Drainage and Water Features
Several small streams and seasonal watercourses flow through the area, generally following the natural contours of the land toward larger tributaries of the Tocantins River system. These waterways have carved shallow valleys into the landscape over time, creating subtle but noticeable changes in elevation across the region.
During the rainy season, temporary wetlands and seasonal ponds form in lower-lying areas, while the dry season reveals the underlying gentle topography more clearly. The drainage patterns follow predictable courses along the natural slope of the land, moving generally northward toward the main river channels.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the broad, relatively flat plateau areas that extend for several kilometers in multiple directions from Bom Jesus do Tocantins. These elevated plains offer consistent, gentle slopes that rarely exceed five degrees, making them ideal for large-scale solar arrays while minimizing grading and construction costs.
Particularly promising areas include the expansive grassland plateaus to the north and west of the municipality, where the terrain remains remarkably consistent across large distances. These locations combine favorable topographical conditions with minimal natural obstacles, allowing for efficient panel placement and maintenance access.
The elevated ridgelines that run roughly northwest to southeast through the region also present excellent opportunities for solar development. These areas benefit from good natural drainage, reduced flooding risk, and consistent exposure conditions across large continuous areas suitable for utility-scale installations.
Areas to avoid for major solar projects include the narrow valleys where seasonal streams flow, as these locations experience periodic flooding and may have environmental restrictions. The few steeper hillsides in the region would also require more extensive site preparation and could present challenges for optimal panel orientation and maintenance access.
Brazil solar PV Stats as a country
