Sooretama, Espírito Santo, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical climate where consistent sunlight is available throughout most of the year, with seasons characterized more by wet and dry periods rather than significant temperature variations.

Solar Energy Production Performance

The solar energy output at Sooretama demonstrates strong performance across all seasons. Summer delivers the highest production at 5.93 kWh per day per kW of installed solar capacity, followed closely by autumn at 5.50 kWh per day. Spring maintains good output at 5.19 kWh per day, while winter shows the lowest but still respectable production at 4.39 kWh per day per kW installed. The ideal times for solar generation at this location are during the summer and autumn months, when output peaks. However, the relatively modest seasonal variation means that solar panels will generate substantial electricity year-round, making this location highly suitable for consistent solar energy production. For optimal performance, solar panels should be installed at a fixed tilt angle of 18 degrees facing north. This angle maximizes total year-round production by accounting for the sun's path throughout the seasons and the location's specific latitude.

Environmental and Weather Challenges

Several local factors could potentially impact solar production efficiency at Sooretama and require consideration during installation:

• High humidity and moisture: The tropical climate brings elevated humidity levels that can promote corrosion of electrical components and reduce panel efficiency over time
• Heavy rainfall during wet seasons: Intense tropical downpours can create temporary shading and may cause water damage if drainage systems are inadequate
• Vegetation growth: The favorable growing conditions mean that trees and plants can quickly establish themselves and create shading issues
• Dust and organic debris: Pollen, leaves, and other organic matter can accumulate on panels, reducing their efficiency

Preventative Installation Measures

To maximize solar energy production despite these challenges, several preventative measures should be implemented during installation. Using marine-grade or specially treated electrical components and mounting systems will help resist corrosion from the humid environment. Ensuring proper drainage around the installation site and using waterproof electrical enclosures will protect against water damage during heavy rains. Regular vegetation management around the solar array is essential, including trimming back any trees or shrubs that could cast shadows on the panels. Installing panels with adequate spacing between rows also helps prevent shading issues as vegetation grows. A routine cleaning and maintenance schedule should be established to remove dust, pollen, and organic debris from panel surfaces. This might need to be more frequent during certain seasons when pollen counts are high or after storms that deposit debris on the panels. The consistently strong solar output throughout the year at Sooretama makes it an ideal location for solar energy generation, provided that proper installation techniques and maintenance practices address the tropical environmental challenges.

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 Sooretama

Seasonal solar PV output for Latitude: -19.0825, Longitude: -40.1425 (Sooretama, 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 18° North in Sooretama, Brazil

To maximize your solar PV system's energy output in Sooretama, Brazil (Lat/Long -19.0825, -40.1425) throughout the year, you should tilt your panels at an angle of 18° 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 Sooretama, 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 Sooretama, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° North in Summer	24° North in Autumn	35° North in Winter	13° 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 Sooretama, 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 Sooretama, Brazil.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Sooretama, Brazil

Topographical Features of Sooretama Region

The area surrounding Sooretama in Espírito Santo state presents a diverse topographical landscape characterized by gently rolling hills and coastal plains typical of Brazil's Atlantic coastal region. The terrain generally slopes eastward toward the Atlantic Ocean, creating a series of undulating hills interspersed with river valleys and floodplains. Elevations in the immediate vicinity range from near sea level along the eastern coastal areas to modest heights of approximately 200-300 meters above sea level in the western portions of the region. The landscape is dominated by remnants of the Atlantic Forest (Mata Atlântica) ecosystem, with the famous Sooretama Biological Reserve protecting significant portions of this endangered biome. The topography includes numerous small streams and tributaries that flow eastward toward larger river systems, creating a network of valleys and ridgelines that give the area its characteristic rolling appearance.

Geological Foundation and Terrain Stability

The underlying geology consists primarily of crystalline basement rocks overlain by sedimentary deposits, creating relatively stable terrain suitable for development. The soil composition varies from sandy coastal soils in the eastern areas to more clay-rich soils in the interior hills. This geological stability, combined with the moderate terrain gradients, provides favorable conditions for large-scale infrastructure development. The region experiences minimal seismic activity and has well-drained soils that reduce concerns about flooding or ground instability. The rolling hills create natural drainage patterns that help manage seasonal rainfall runoff effectively.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be found on the gentler slopes and plateau areas west and southwest of Sooretama proper. These areas offer several key advantages including relatively flat to gently sloping terrain that minimizes grading requirements and construction costs while maximizing solar panel efficiency through optimal positioning. The cleared agricultural lands and pasturelands in these western areas present fewer environmental constraints compared to the forested regions closer to the biological reserve. These open areas already have established access roads and are typically located away from the most sensitive ecological zones, making permitting and development more straightforward. Areas with southern and southeastern exposures on the moderate slopes would be particularly well-suited, as they can take advantage of optimal solar positioning while maintaining reasonable construction accessibility. The higher elevation areas west of the town center offer additional benefits including potentially better air circulation for cooling equipment and reduced humidity compared to lower-lying areas.

Infrastructure and Access Considerations

The region benefits from reasonable road access via state highways connecting to larger population centers, which would facilitate construction and maintenance operations for solar installations. The existing electrical grid infrastructure, while requiring upgrades for large-scale solar integration, provides a foundation for connecting new renewable energy projects to the broader electrical network. Areas near existing transmission lines but away from the most environmentally sensitive forest reserves would offer the best combination of technical feasibility and regulatory approval prospects. The relatively stable terrain and established transportation corridors make the western and southwestern areas particularly attractive for utility-scale solar development.
