Salgado, Sergipe, Brazil represents an excellent location for year-round solar energy generation. Located in the tropical zone at coordinates -11.0743, -37.4718, this area benefits from consistent sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than the dramatic temperature changes seen in temperate regions.

Solar Energy Production Potential

The solar energy output data for Salgado demonstrates strong year-round performance. Spring delivers the highest production at 6.78 kWh per day per kW of installed solar capacity, closely followed by summer at 6.74 kWh per day. Autumn maintains solid performance at 6.00 kWh per day, while winter shows the lowest but still respectable output of 5.11 kWh per day. The best times for solar generation at this location are spring and summer months, when output peaks at nearly 6.8 kWh per day per kW installed. Even during the lowest-producing winter season, the location still generates over 5 kWh per day per kW, indicating reliable year-round solar potential. For optimal performance, fixed solar panels at this location should be tilted at 10 degrees toward the north. This angle maximizes total annual energy production by accounting for the sun's path throughout the year and the site's specific latitude.

Environmental and Weather Challenges

Several local factors could potentially impact solar energy production in Salgado:

• Seasonal rainfall: The tropical wet season can bring heavy rains and increased cloud cover, reducing solar irradiance during certain months
• High humidity: Coastal tropical locations often experience elevated humidity levels that can affect panel efficiency and promote corrosion
• Salt air exposure: If near the coast, salt-laden air can cause accelerated corrosion of metal components and reduce panel transparency over time
• Dust and debris accumulation: Dry seasons may lead to dust buildup on panels, while wet seasons can deposit organic matter

Preventative Measures for Optimal Performance

To maximize solar energy production despite these challenges, several installation strategies should be considered: Panel maintenance becomes crucial in this environment. Regular cleaning schedules should account for both dust accumulation during dry periods and organic debris after heavy rains. Installing panels with adequate spacing allows for proper air circulation, helping to manage humidity-related issues. Component selection plays a vital role in long-term performance. Using marine-grade aluminum frames and stainless steel mounting hardware helps resist corrosion from salt air and high humidity. Anti-reflective coatings on panels can maintain transparency despite environmental exposure. Proper drainage design ensures rainwater flows away from mounting points and electrical connections. Installing panels at the recommended 10-degree tilt naturally assists with self-cleaning during rain events while optimizing energy capture. Despite these environmental considerations, Salgado's consistent tropical sunlight and strong seasonal production figures make it a highly suitable location for solar PV installations with proper planning and maintenance protocols.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 10° North in Salgado, Brazil

To maximize your solar PV system's energy output in Salgado, Brazil (Lat/Long -11.0743, -37.4718) throughout the year, you should tilt your panels at an angle of 10° 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 Salgado, 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 Salgado, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° South in Summer	17° North in Autumn	27° North in Winter	5° 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 Salgado, 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 Salgado, Brazil

Topographical Features Around Salgado

Salgado is situated in the northeastern region of Brazil within the state of Sergipe, positioned along the coastal lowlands near the Atlantic Ocean. The terrain surrounding this location is characterized by relatively flat to gently undulating topography, typical of the coastal plains that extend inland from the Brazilian shoreline. The elevation in this area remains consistently low, rarely exceeding 100 meters above sea level within a considerable radius of the town. The landscape is dominated by sedimentary formations that create a stable geological foundation with minimal steep slopes or dramatic elevation changes. Rolling hills occasionally punctuate the otherwise level terrain, but these features are generally modest in height and present gentle gradients rather than sharp inclines. The coastal influence has shaped much of the regional topography through centuries of marine and fluvial processes, resulting in broad, open spaces with excellent exposure to solar radiation throughout most of the year.

Drainage and Water Features

Several small rivers and seasonal watercourses traverse the region, flowing generally eastward toward the Atlantic Ocean. These waterways have carved shallow valleys into the landscape, creating subtle variations in elevation but maintaining the overall flat character of the terrain. During the wet season, temporary wetlands may form in lower-lying areas, though these typically drain efficiently due to the gentle slopes and proximity to the ocean. The drainage patterns create natural boundaries and corridors through the landscape, but the modest scale of these features means they rarely present significant obstacles to large-scale development projects. The well-drained soils and stable water table conditions contribute to the area's suitability for various land uses.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie inland from Salgado, particularly in the areas extending westward and southwestward from the coastal zone. These inland plains offer several advantages for solar development, including consistent topography, minimal shading from natural features, and reduced exposure to coastal weather extremes. The elevated plateau areas, though still relatively low in absolute terms, provide excellent drainage and stable ground conditions ideal for supporting large solar arrays. These locations typically feature open grasslands or agricultural areas with minimal tree cover, reducing the need for extensive land clearing operations. The gentle slopes present in these areas facilitate efficient water runoff while maintaining optimal panel orientation possibilities. Areas located approximately 10 to 30 kilometers inland from the immediate coastal zone represent particularly attractive sites for solar development. These locations balance the benefits of stable weather patterns with reduced exposure to salt-laden coastal winds that can affect equipment longevity. The terrain in these zones remains predominantly flat with occasional gentle rises that can be advantageous for solar panel positioning and site drainage.

Infrastructure Considerations

The relatively flat topography throughout the region simplifies infrastructure development and maintenance access for large-scale solar installations. Road construction and utility line installation face minimal topographical obstacles, while the stable ground conditions reduce foundation requirements compared to more challenging terrains. The absence of significant elevation changes means that solar installations can be designed with consistent panel configurations across extensive areas, optimizing both construction efficiency and energy production. The predictable drainage patterns and moderate relief ensure that stormwater management systems can be implemented effectively without complex engineering solutions typically required in more varied topographical settings.
