Guiratinga, Brazil presents an excellent location for year-round solar energy generation, with consistently high solar output throughout all seasons. Located in the tropical region of Mato Grosso state, this area benefits from abundant sunshine and relatively stable energy production across the entire year.
Solar Energy Output Performance
The solar energy production data for Guiratinga shows remarkably consistent performance throughout the year. Spring delivers the highest output at 6.20 kWh per day per kW of installed solar capacity, closely followed by summer at 6.19 kWh per day. Even during the lower-producing seasons of autumn and winter, the location maintains strong output levels of 5.77 kWh and 5.79 kWh per day respectively. This minimal seasonal variation makes Guiratinga particularly attractive for solar installations, as energy production remains predictable and reliable year-round. The difference between the highest and lowest producing seasons is only about 7%, which is exceptionally small compared to many other global locations.Optimal Panel Installation
For maximum year-round solar energy production at this location, solar panels should be installed at a fixed tilt angle of 16 degrees facing north. This optimal angle is calculated by analyzing daily solar elevation angles at the latitude, determining daily optimal panel positioning, and weighting these angles using solar irradiance data while accounting for Earth's elliptical orbit around the sun.Environmental and Weather Challenges
Several local factors in Guiratinga could potentially impact solar energy production and require careful consideration during installation:- Intense tropical rainfall: The wet season brings heavy downpours that can reduce solar output and potentially damage equipment if not properly protected
- High humidity levels: Persistent moisture can lead to corrosion of metal components and degradation of electrical connections
- Dust accumulation: During dry periods, dust and debris can accumulate on panel surfaces, significantly reducing efficiency
- Extreme heat: High temperatures can reduce panel efficiency and accelerate equipment degradation
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be implemented:- Robust waterproofing: Use high-quality sealing materials and proper drainage systems to protect electrical components from moisture infiltration
- Corrosion-resistant materials: Select aluminum or stainless steel mounting systems and marine-grade wiring to withstand humid conditions
- Regular cleaning protocols: Establish routine panel cleaning schedules, particularly during dusty periods, or install automated cleaning systems
- Adequate ventilation: Design installations with proper airflow beneath panels to reduce operating temperatures and improve efficiency
- Quality inverters with cooling: Install inverters in shaded, well-ventilated areas or use models with active cooling systems
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 Guiratinga
Seasonal solar PV output for Latitude: -16.3684, Longitude: -53.5735 (Guiratinga, 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 Guiratinga, Brazil
To maximize your solar PV system's energy output in Guiratinga, Brazil (Lat/Long -16.3684, -53.5735) 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 Guiratinga, 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 Guiratinga, 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 | 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'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 Guiratinga, 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 Guiratinga, Brazil
Topographical Features Around Guiratinga
Guiratinga sits in the heart of Mato Grosso state within Brazil's expansive Cerrado biome, characterized by gently rolling terrain typical of the Brazilian Central Plateau. The landscape around this municipality features predominantly flat to mildly undulating topography, with elevations ranging from approximately 400 to 600 meters above sea level. The region forms part of the vast sedimentary basin that defines much of central Brazil, creating relatively stable geological conditions with minimal steep gradients.
The area displays the classic Cerrado landscape of open savannas interspersed with gallery forests along waterways. Rolling hills create a subtle wave-like pattern across the terrain, but these elevations are generally modest and present few significant obstacles to development. The topography becomes slightly more varied toward the eastern portions of the region, where the land begins its gradual transition toward the more elevated areas of the Brazilian Highlands.
Several small rivers and streams traverse the landscape, creating shallow valleys that add gentle contours to an otherwise relatively uniform terrain. These waterways, including tributaries of the Paraguay River system, have carved modest depressions into the landscape over geological time, but the overall character remains one of accessible, gently sloping land with good drainage characteristics.
Optimal Areas for Large-Scale Solar Development
The expansive flat and gently rolling areas immediately surrounding Guiratinga present excellent opportunities for large-scale solar photovoltaic installations. The most promising locations lie on the broader plateau surfaces where the terrain remains consistently level across extensive areas, minimizing the need for significant grading or terracing during construction.
Areas to the north and northwest of Guiratinga offer particularly favorable conditions, where the landscape opens into vast stretches of relatively uniform elevation with minimal natural obstacles. These zones benefit from stable geological foundations and good accessibility via existing transportation networks, making them highly suitable for utility-scale solar development.
The southern approaches to the municipality also present substantial opportunities, particularly where the terrain maintains consistent gentle slopes that can be easily accommodated by modern solar mounting systems. These areas offer the additional advantage of being somewhat elevated, providing natural drainage while maintaining the accessibility essential for construction and maintenance operations.
Regions with south-facing slopes throughout the area deserve special consideration, as these orientations can enhance energy capture efficiency when properly designed. The gentle nature of most slopes in the region means that large installations can take advantage of natural terrain features without requiring extensive site preparation or complex engineering solutions.
Areas to avoid for large-scale development include the immediate vicinity of waterways where seasonal flooding might occur, and the steeper terrain found in scattered locations throughout the region. However, these challenging areas represent a relatively small portion of the overall landscape, leaving abundant suitable land for solar development across the broader Guiratinga region.
