Located in the tropical region of central Brazil, this area benefits from stable sunlight patterns that make it highly suitable for solar photovoltaic installations.
Seasonal Solar Performance
The solar energy output at Cocalinho shows impressive consistency across all meteorological seasons. Summer produces 5.69 kWh per day per kW of installed solar capacity, while autumn performs slightly better at 5.93 kWh per day. Winter delivers the highest output at 6.31 kWh per day, and spring maintains strong performance at 6.18 kWh per day. The winter and spring months emerge as the ideal times for solar generation at this location, with winter showing the peak performance. This pattern is typical for tropical locations where the dry season often coincides with clearer skies and optimal solar conditions.Optimal Panel Configuration
For maximum year-round energy production at Cocalinho, Mato Grosso, solar panels should be installed at a fixed tilt angle of 14 degrees facing north. This angle has been calculated to optimize total annual solar output by accounting for the sun's path throughout the year and the location's specific latitude.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production at this location:- Wet season impacts: Heavy rainfall and increased cloud cover during the wet season can reduce solar irradiance and panel efficiency
- Dust and debris accumulation: The dry season may lead to dust buildup on panel surfaces, reducing light transmission
- High humidity levels: Tropical humidity can affect electrical components and create condensation issues
- Vegetation growth: Rapid plant growth in tropical climates can create shading issues if not properly managed
Preventative Installation Measures
To maximize energy production despite these challenges, several installation strategies should be implemented:- Enhanced drainage systems: Install proper drainage around panel arrays to prevent water pooling and ensure quick runoff during heavy rains
- Regular cleaning protocols: Establish routine panel cleaning schedules, particularly during dry periods when dust accumulation is highest
- Improved ventilation: Design mounting systems that allow adequate airflow beneath panels to reduce heat buildup and humidity-related issues
- Vegetation management: Plan for ongoing landscape maintenance to prevent trees and bushes from creating shade over solar installations
- Weather-resistant components: Use corrosion-resistant mounting hardware and electrical components designed for high-humidity tropical 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 Cocalinho
Seasonal solar PV output for Latitude: -13.8027, Longitude: -51.1534 (Cocalinho, 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 14° North in Cocalinho, Brazil
To maximize your solar PV system's energy output in Cocalinho, Brazil (Lat/Long -13.8027, -51.1534) throughout the year, you should tilt your panels at an angle of 14° 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 Cocalinho, 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 Cocalinho, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° South in Summer | 20° North in Autumn | 29° North in Winter | 8° 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 Cocalinho, 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 Cocalinho, 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 Cocalinho, Brazil
Topographical Features Around Cocalinho
Cocalinho sits in the heart of Brazil's Mato Grosso state, positioned within the vast Cerrado savanna region that characterizes much of central Brazil. The landscape around this municipality features predominantly flat to gently rolling terrain, with elevations typically ranging between 200 and 400 meters above sea level. This area represents part of the Brazilian Shield, an ancient geological formation that creates relatively stable and uniform topographical conditions across extensive areas.
The region displays the classic characteristics of the Cerrado biome, with expansive grasslands interspersed with scattered trees and occasional patches of gallery forest along waterways. The terrain is generally well-drained, with a network of seasonal streams and rivers that flow toward the Araguaia River system. The soil composition consists primarily of lateritic soils typical of tropical savanna environments, which tend to be well-weathered and relatively nutrient-poor but structurally stable.
Local topography shows minimal variation in elevation across large areas, creating natural plateaus and broad, open spaces that extend for kilometers with only gentle undulations. The landscape lacks significant hills, mountains, or deep valleys that might create substantial shading or access challenges. Vegetation in the immediate vicinity consists mainly of native Cerrado grasses and shrubs, with agricultural conversion having transformed much of the surrounding area into cattle ranching operations and soybean cultivation.
Optimal Areas for Large-Scale Solar Development
The expansive flat terrain surrounding Cocalinho presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas lie on the elevated plateaus to the north and east of the municipality, where the combination of minimal slope variation and stable soil conditions creates ideal foundation requirements for solar arrays. These areas benefit from consistent elevation profiles that minimize the need for extensive site preparation or grading work.
Agricultural lands that have been previously cleared and leveled for farming operations represent particularly attractive locations for solar development. These areas already possess established access roads and electrical infrastructure connections, reducing development costs significantly. The existing agricultural zones demonstrate proven land stability and drainage characteristics essential for long-term solar installations.
Areas with southern exposure on gentle slopes offer additional advantages, though the predominantly flat nature of the region means that orientation flexibility remains high throughout most potential sites. The absence of significant topographical obstacles such as ridges, deep valleys, or dense forest coverage means that large continuous arrays can be planned without major geographical constraints.
The well-drained lateritic soils common throughout the region provide stable foundations that resist erosion and settling, crucial factors for maintaining solar panel alignment over decades of operation. Additionally, the open savanna environment ensures minimal shading issues from natural vegetation, while the existing transportation infrastructure developed for agricultural activities facilitates equipment access and maintenance operations for solar facilities.
