Jaciara, Brazil represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropical region of Mato Grosso state, this area benefits from the consistent sunlight patterns typical of tropical climates, where seasonal variations are primarily defined by wet and dry periods rather than dramatic changes in solar availability.
Solar Energy Production Potential
The solar energy output data for Jaciara demonstrates remarkably consistent performance throughout the year. Summer delivers the highest production at 6.11 kWh per day per installed kilowatt, while the other seasons maintain strong output levels: autumn at 5.59 kWh/day, winter at 5.64 kWh/day, and spring at 5.86 kWh/day per kilowatt of installed capacity. This consistency makes Jaciara particularly attractive for solar installations, as there are no severely underperforming seasons that would create significant gaps in energy production. The relatively small variation between the best and worst performing seasons—less than 10%—provides reliable energy generation year-round.Optimal Installation Configuration
For fixed solar panel installations at this location, the ideal tilt angle is 16 degrees facing north. This angle has been calculated to maximize total annual solar energy production by accounting for the sun's path throughout the year, Earth's orbital patterns, and the specific latitude of Jaciara.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production in Jaciara and require careful consideration during installation planning. The region's tropical wet season brings heavy rainfall and increased cloud cover, which can temporarily reduce solar output during peak wet months. While the annual production figures already account for this seasonal variation, installers should ensure proper drainage systems and waterproofing to protect equipment during intense rainfall periods. Dust accumulation presents another significant challenge, particularly during the dry season when agricultural activities and unpaved roads can generate considerable airborne particles. The surrounding agricultural landscape of Mato Grosso, known for extensive farming operations, contributes to this dust problem. High humidity levels throughout much of the year can affect electrical connections and components if not properly sealed and protected. The combination of heat and moisture creates conditions that can accelerate corrosion of metal components and degrade electrical connections over time.Preventative Measures for Optimal Performance
Several installation strategies can help mitigate these environmental challenges:- Install panels with adequate spacing and ventilation to prevent moisture buildup and allow for natural cleaning during rainfall
- Use high-quality weatherproof electrical enclosures and connections rated for tropical conditions
- Design mounting systems with proper drainage to prevent water pooling around equipment
- Plan for regular cleaning schedules, particularly during dry season months when dust accumulation peaks
- Select components with appropriate IP ratings for humid, dusty environments
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 Jaciara
Seasonal solar PV output for Latitude: -15.8956, Longitude: -55.0224 (Jaciara, 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 16° North in Jaciara, Brazil
To maximize your solar PV system's energy output in Jaciara, Brazil (Lat/Long -15.8956, -55.0224) 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 Jaciara, 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 Jaciara, 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 |
|---|---|---|---|
| 0° in Summer | 22° North in Autumn | 32° North in Winter | 10° 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.

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 Jaciara, Brazil
Topographical Features Around Jaciara
Jaciara sits in the heart of Brazil's Mato Grosso state, positioned within the vast Pantanal basin region and the southern edge of the Amazon transition zone. The landscape around this municipality is characterized by relatively flat to gently rolling terrain, typical of the Brazilian Central Plateau. Elevations in the immediate area range from approximately 200 to 400 meters above sea level, creating a predominantly low-relief environment with gradual slopes and wide valleys.
The region features extensive areas of cerrado, Brazil's tropical savanna ecoregion, which consists of grasslands interspersed with scattered trees and gallery forests along waterways. This landscape is punctuated by seasonal wetlands and small tributaries that eventually drain into the Paraguay River system. The terrain is generally well-drained during dry periods, though some lower-lying areas experience seasonal flooding during the wet season.
Rolling hills and gentle ridges create a varied but manageable topography, with most slopes remaining under 10 degrees. The soil composition includes lateritic soils typical of tropical regions, with areas of sandy and clay-rich substrates that have formed over geological time from the weathering of ancient crystalline rocks of the Brazilian Shield.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Jaciara would be the elevated plateaus and gentle ridges that extend northwest and southeast of the town center. These areas offer several advantages including consistent elevation above flood-prone zones, minimal slope variations that reduce installation complexity, and existing cleared areas within the cerrado landscape that require less environmental disruption.
The southeastern quadrant presents particularly favorable conditions, where the terrain consists of broad, flat-topped hills with excellent drainage and stable soil conditions. These elevated areas remain above the seasonal water table fluctuations and provide natural protection from the flooding patterns that affect lower elevations during wet periods.
Areas along the higher ground extending toward the northeast also show promise, featuring gentle south-facing slopes that would be ideal for solar panel orientation in the Southern Hemisphere. The existing road infrastructure connecting to Highway BR-364 makes these locations accessible for construction and maintenance activities.
Locations to avoid would include the immediate floodplains near the Tenente Amaral River and other waterways, as well as the more heavily forested gallery forest areas that would require significant clearing. The lower-lying areas south and southwest of Jaciara experience more pronounced seasonal water level changes and would present greater challenges for permanent solar installations.
Brazil solar PV Stats as a country
