Buriti dos Lopes, Brazil presents an excellent location for year-round solar energy generation. Located in the tropical region at coordinates -3.2936, -41.8181, this area benefits from consistent sunlight throughout most of the year, with seasons typically defined by wet and dry periods rather than significant temperature variations.
Solar Energy Output Performance
The solar energy production data for this location shows consistently strong performance across all seasons. Summer generates 5.88 kWh per day per kW of installed solar capacity, while autumn produces slightly more at 5.90 kWh per day per kW. Winter performance increases to 6.28 kWh per day per kW, and spring delivers the highest output at 6.96 kWh per day per kW. This seasonal pattern indicates that the cooler, drier months of winter and spring provide optimal conditions for solar generation, likely due to clearer skies and reduced atmospheric moisture. The relatively high and consistent output across all seasons makes this location highly suitable for solar installations.Optimal Panel Configuration
For fixed panel installations at this location, the ideal tilt angle to maximize total year-round solar production is 4 degrees North. This shallow angle reflects the location's proximity to the equator, where the sun remains relatively high in the sky throughout the year.Environmental and Weather Challenges
Several local factors could potentially impact solar production efficiency in Buriti dos Lopes:- Heavy rainfall during wet season: Tropical regions experience intense precipitation that can reduce solar irradiance and create water-related maintenance issues
- High humidity levels: Persistent moisture in the air can affect panel efficiency and promote corrosion of electrical components
- Dust and particulate matter: Dry seasons may bring increased dust accumulation on panel surfaces
- Tropical storms: Seasonal weather patterns may include high winds and severe weather events
Preventative Measures for Optimal Performance
To maximize energy production and system longevity, several installation strategies should be considered: Drainage and Ventilation: Installing panels with adequate spacing and proper drainage systems helps prevent water accumulation and allows for natural cleaning during rainfall. Good ventilation behind panels reduces heat buildup and improves efficiency. Corrosion-Resistant Materials: Using marine-grade aluminum frames, stainless steel fasteners, and weather-resistant electrical enclosures helps combat the effects of high humidity and occasional salt air. Regular Maintenance Schedule: Implementing a cleaning routine during dry periods removes dust buildup, while post-storm inspections ensure panels remain properly aligned and undamaged. Robust Mounting Systems: Installing reinforced mounting structures designed for tropical wind loads provides protection against severe weather while maintaining the optimal 4-degree tilt angle. Despite these environmental considerations, the consistently high solar output throughout the year makes Buriti dos Lopes an excellent location for solar energy investment, with proper installation and maintenance practices ensuring optimal long-term performance.Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 4° North in Buriti Dos Lopes, Brazil
To maximize your solar PV system's energy output in Buriti Dos Lopes, Brazil (Lat/Long -3.2936, -41.8181) throughout the year, you should tilt your panels at an angle of 4° 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 Buriti Dos Lopes, 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 Buriti Dos Lopes, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 4° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 10° North in Autumn | 19° North in Winter | 3° 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 Buriti Dos Lopes, Brazil
Topographical Features of Buriti dos Lopes
Buriti dos Lopes sits in the northeastern region of Brazil within PiauĂ state, positioned in an area characterized by relatively gentle topography typical of the Brazilian interior. The landscape around this municipality features predominantly flat to gently rolling terrain with elevations that rarely exceed modest undulations across the countryside. This region forms part of the broader Caatinga biome transition zone, where the terrain gradually shifts from the more elevated areas of the interior toward the coastal plains.
The surrounding geography consists mainly of sedimentary formations that have created a landscape of subtle hills and shallow valleys. These geological features result in terrain that slopes gradually rather than presenting steep gradients or dramatic elevation changes. The area experiences typical semi-arid topographical characteristics, with scattered low-lying hills interspersed among broader flat expanses that extend for considerable distances.
Water features in the region include seasonal streams and small watercourses that flow intermittently, creating shallow depressions and gentle valley systems throughout the landscape. These drainage patterns contribute to the overall gentle undulating character of the terrain without creating significant topographical barriers or steep-sided valleys.
Optimal Areas for Large-Scale Solar Development
The relatively flat terrain surrounding Buriti dos Lopes presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas for such developments would be the extensive flat plains that stretch in multiple directions from the town center. These level areas offer the advantage of minimal ground preparation requirements and allow for efficient installation of solar panel arrays with consistent orientation and spacing.
The gently sloping areas with southern exposure would be particularly advantageous for solar installations, as they can be oriented to maximize solar collection while maintaining good drainage characteristics. These slight gradients help prevent water accumulation during the rainy season while providing stable foundations for solar infrastructure.
Areas to the east and west of Buriti dos Lopes contain some of the most promising terrain for solar development, where the landscape opens into broad, relatively flat expanses with minimal vegetation density. These zones offer the dual benefits of accessible terrain and reduced environmental impact from land clearing activities.
The northern approaches to the municipality also present suitable conditions, where the topography remains consistently level over large areas. These locations would allow for the development of substantial solar farms with minimal grading or earthwork requirements, reducing both construction costs and environmental disruption.
When selecting specific sites, preference should be given to areas with gentle slopes facing south or southeast, as these orientations provide optimal conditions for solar panel placement. The relatively stable geological conditions throughout the region mean that most flat or gently sloping areas can support the infrastructure requirements of large-scale solar installations without significant foundation concerns.
