Uruburetama, CearĂ¡, Brazil presents an excellent location for year-round solar photovoltaic energy generation. Located in the tropics at coordinates -3.6288, -39.5528, this region benefits from consistent sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than dramatic changes in solar availability.
Solar Energy Production Potential
The solar energy output data for Uruburetama demonstrates strong and reliable performance across all seasons. During summer, solar panels can be expected to generate 5.94 kWh per day for each kW of installed capacity. Autumn production drops slightly to 5.68 kWh/day per kW, while winter shows improved performance at 6.19 kWh/day per kW. Spring emerges as the most productive season, delivering an impressive 7.11 kWh per day per kW of installed solar capacity. This seasonal variation of approximately 25% between the lowest and highest production periods indicates relatively stable solar generation throughout the year, making this location highly suitable for solar energy projects. For optimal year-round energy production, fixed solar panels should be tilted at 4 degrees North. This angle maximizes total annual solar output by accounting for the sun's path throughout the year and the location's proximity to the equator.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production in Uruburetama and require careful consideration during installation planning. Tropical Climate Impacts The tropical climate brings high humidity levels throughout much of the year, which can reduce solar panel efficiency and accelerate degradation of electrical components. Additionally, the region's wet season can bring extended periods of cloud cover and heavy rainfall, temporarily reducing solar irradiance and energy output. Dust and Debris Accumulation During dry periods, dust accumulation on solar panels can significantly reduce their efficiency. The combination of dry conditions followed by heavy rains can create a cycle of soiling that requires regular attention. Extreme Weather Events Tropical storms and heavy rainfall events can pose risks to solar installations through high winds, hail, and flooding. The intense UV radiation typical of tropical locations can also accelerate the degradation of solar panel materials over time.Preventative Measures for Optimal Performance
Several strategies can help maximize solar energy production and system longevity in Uruburetama's tropical environment.- Install panels with anti-reflective and self-cleaning coatings to minimize dust accumulation and improve light absorption
- Implement regular cleaning schedules, particularly during dry seasons, to maintain optimal panel efficiency
- Use high-quality, humidity-resistant electrical components and ensure proper sealing of all connections
- Design mounting systems to withstand high winds and provide adequate drainage during heavy rainfall
- Select solar panels with enhanced UV resistance and longer warranties suitable for tropical climates
Installation Considerations
Proper ventilation around solar panels becomes crucial in this humid environment to prevent overheating and maintain efficiency. Mounting systems should allow adequate airflow beneath panels while providing robust structural support against tropical weather conditions. Ground-mounted systems may require elevated positioning to avoid potential flooding during heavy rain periods. Additionally, vegetation management around installations becomes important to prevent shading and maintain access for cleaning and maintenance. Despite these challenges, Uruburetama's consistently strong solar production potential throughout all seasons makes it an attractive location for solar energy projects. With proper planning and installation techniques that address the tropical climate factors, solar installations can achieve excellent long-term performance and energy output.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 Uruburetama
Seasonal solar PV output for Latitude: -3.6288, Longitude: -39.5528 (Uruburetama, 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 4° North in Uruburetama, Brazil
To maximize your solar PV system's energy output in Uruburetama, Brazil (Lat/Long -3.6288, -39.5528) 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 Uruburetama, 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 Uruburetama, 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 |
|---|---|---|---|
| 12° South in Summer | 10° North in Autumn | 19° North in Winter | 2° 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.

Topography for solar PV around Uruburetama, Brazil
Topographical Features of Uruburetama Region
The area surrounding Uruburetama in CearĂ¡ state, Brazil, is characterized by relatively gentle topography that forms part of the broader Brazilian Northeast plateau system. This region sits within the Caatinga biome and features predominantly flat to gently rolling terrain with elevations typically ranging from 200 to 400 meters above sea level. The landscape is punctuated by occasional low hills and scattered rock outcroppings, but lacks significant mountainous formations that would create major obstacles for large-scale development projects. The terrain around Uruburetama consists primarily of crystalline basement rock formations covered by thin layers of sedimentary deposits. These geological foundations create a stable base with moderate drainage patterns. The area experiences a semi-arid climate with distinct wet and dry seasons, which has shaped the local topography through weathering processes that have created relatively smooth, undulating surfaces with occasional areas of exposed bedrock.Drainage and Surface Characteristics
The regional drainage system is composed of seasonal streams and intermittent water courses that flow primarily during the rainy season. These waterways have carved shallow valleys and depressions throughout the landscape, creating a gently undulating surface rather than steep-sided valleys or dramatic elevation changes. The overall gradient of the land tends to slope gradually toward the Atlantic Ocean to the north, with most water courses eventually feeding into larger river systems that drain toward the coast. Surface conditions in the Uruburetama area are generally characterized by sparse vegetation typical of the Caatinga ecosystem, with drought-resistant shrubs, cacti, and small trees scattered across the landscape. The soil composition varies from sandy to clay-rich depending on local geological conditions, with many areas featuring a thin layer of topsoil over weathered rock substrates.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Uruburetama would be the extensive flat to gently sloping areas that dominate the regional landscape. These areas offer several advantages including minimal grading requirements, reduced construction costs, and optimal positioning for solar panel arrays. The relatively stable geological foundation provides excellent support for mounting systems and infrastructure. Areas with southern-facing slopes of less than 5 degrees would be particularly well-suited for solar development, as they provide natural orientation advantages while maintaining accessibility for construction and maintenance vehicles. The sparse vegetation cover in much of the region means that land clearing requirements would be minimal, reducing both environmental impact and preparation costs. The elevated plateau areas around Uruburetama also offer advantages in terms of air circulation and temperature management, which can improve solar panel efficiency. These locations typically experience consistent wind patterns that help cool equipment and reduce the buildup of dust and debris on solar surfaces.Infrastructure Considerations
The topography around Uruburetama is generally favorable for the development of supporting infrastructure required for large-scale solar installations. The relatively flat terrain facilitates the construction of access roads, transmission lines, and maintenance facilities without requiring extensive earthwork or specialized engineering solutions for extreme slopes or unstable ground conditions. Areas within reasonable proximity to existing transportation corridors would be most practical for solar development, as the gentle topography allows for straightforward connection to regional electrical grid infrastructure. The stable ground conditions and moderate elevation changes also support the installation of inverter stations, substations, and other electrical equipment necessary for large-scale solar operations.Brazil solar PV Stats as a country
