Nossa Senhora Aparecida, Sergipe, Brazil presents an excellent location for year-round solar energy generation, benefiting from its tropical position where consistent sunlight is available throughout most of the year.

Solar Energy Performance

The solar energy output at this location shows strong performance across all seasons. Spring delivers the highest production at 6.68 kWh per day per kW of installed solar capacity, closely followed by summer at 6.25 kWh per day. Even during the lowest production period in winter, the location still generates a respectable 4.81 kWh per day per kW, while autumn provides 5.50 kWh per day. For optimal year-round energy production, solar panels should be installed at a fixed tilt angle of 9 degrees facing north. This angle maximizes total annual solar output by accounting for the sun's position throughout the year and the location's latitude.

Environmental and Weather Factors

Being located in the tropics, Nossa Senhora Aparecida faces several environmental challenges that can impact solar energy production: Humidity and Moisture The tropical climate brings high humidity levels year-round, which can cause moisture buildup on solar panels and reduce their efficiency. Regular cleaning schedules and proper drainage systems around installations help maintain optimal performance. Seasonal Rainfall Patterns Tropical regions typically experience distinct wet and dry seasons rather than traditional four-season patterns. Heavy rainfall during wet seasons can temporarily reduce solar output due to cloud cover and may cause dirt and debris accumulation on panels. Dust and Particulate Matter During dry periods, dust accumulation on solar panels can significantly reduce energy production. The combination of high humidity followed by dry conditions can create stubborn residue on panel surfaces.

Preventative Measures for Installation

To maximize solar energy production despite these challenges, several installation strategies prove effective:

• Install panels with adequate spacing for air circulation to reduce moisture-related issues
• Implement regular cleaning schedules, particularly during transitions between wet and dry seasons
• Use anti-reflective coatings that also provide easier cleaning properties
• Ensure proper drainage around mounting systems to prevent water pooling
• Select corrosion-resistant mounting hardware suitable for humid tropical conditions

Despite these environmental considerations, Nossa Senhora Aparecida remains highly suitable for solar energy generation due to its consistent tropical sunlight and strong seasonal performance figures across all periods of the year.

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 Nossa Senhora Aparecida

Seasonal solar PV output for Latitude: -10.2964, Longitude: -37.4871 (Nossa Senhora Aparecida, 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 9° North in Nossa Senhora Aparecida, Brazil

To maximize your solar PV system's energy output in Nossa Senhora Aparecida, Brazil (Lat/Long -10.2964, -37.4871) throughout the year, you should tilt your panels at an angle of 9° 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 Nossa Senhora Aparecida, 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 Nossa Senhora Aparecida, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° South in Summer	16° North in Autumn	26° North in Winter	4° 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 Nossa Senhora Aparecida, 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 Nossa Senhora Aparecida, 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 Nossa Senhora Aparecida, Brazil

Topographical Features of Nossa Senhora Aparecida Region

Nossa Senhora Aparecida is located in the state of Sergipe, Brazil, positioned within the northeastern coastal region of the country. The topography surrounding this area is characterized by relatively gentle terrain typical of the Atlantic coastal plain. The landscape consists primarily of low-lying areas with modest elevation changes, creating a predominantly flat to gently rolling terrain that extends inland from the Atlantic Ocean.

The region sits within the broader Sergipe coastal lowlands, where elevations rarely exceed 200 meters above sea level. The terrain is punctuated by scattered low hills and gentle undulations that create a subtly varied landscape without dramatic elevation changes. Small river valleys and drainage channels cut through the area, creating minor depressions and slightly more pronounced topographical features, though these remain relatively shallow compared to mountainous regions elsewhere in Brazil.

The coastal influence is evident in the overall flatness of the terrain, as sedimentary deposits from ancient marine environments have created stable, level surfaces across much of the region. Sandy soils are common, interspersed with areas of clay and mixed sedimentary materials that reflect the area's geological history as part of the coastal plain formation.

Optimal Areas for Large-Scale Solar Development

The gentle topography surrounding Nossa Senhora Aparecida presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas for solar development are the extensive flat to gently sloping plains that dominate the landscape. These areas offer the dual advantages of minimal site preparation requirements and optimal positioning for solar panel arrays.

The broad, open areas of relatively level terrain provide ideal conditions for utility-scale solar farms, as they minimize the need for extensive grading and earthwork while maximizing the potential for efficient panel layout and maintenance access. The stable, well-drained soils found across much of the region offer good foundation conditions for solar mounting systems.

Areas with gentle south-facing slopes present particularly attractive opportunities, as they can enhance solar collection efficiency while maintaining the practical advantages of manageable terrain. The low hills scattered throughout the region often feature such favorable orientations, making them prime candidates for solar development when combined with adequate access infrastructure.

The relatively sparse vegetation and limited agricultural intensity in many areas of the surrounding region also contribute to the suitability for solar development. Large tracts of underutilized land with minimal environmental constraints provide opportunities for substantial solar installations without significant land use conflicts. The proximity to existing electrical infrastructure and transportation networks further enhances the viability of solar projects in the flatter, more accessible portions of the surrounding landscape.
