Maravilha, Brazil represents an excellent location for year-round solar energy generation, with its tropical positioning delivering consistent sunlight throughout most of the year. Located at coordinates -9.2256, -37.3762, this area benefits from the typical tropical climate pattern where seasons are characterized more by wet and dry periods rather than the temperature variations found in temperate regions.
Solar Energy Production Performance
The solar energy output at this location shows strong performance across all seasons, with some notable seasonal variations. Spring emerges as the peak production period, generating 7.02 kWh per day per kW of installed solar capacity. Summer follows closely with 6.82 kWh per day per kW, making these two seasons the optimal time for solar energy generation. Autumn production drops to 5.82 kWh per day per kW, while winter shows the lowest output at 5.09 kWh per day per kW of installed capacity. Despite winter being the weakest season, the production levels remain quite respectable for solar energy generation, demonstrating the location's year-round viability.Optimal Panel Installation
For maximum energy production throughout the year, solar panels at this Maravilha location should be installed at a fixed tilt angle of 8 degrees facing North. This angle has been calculated to optimize total annual solar output by accounting for the sun's path throughout the year and the Earth's elliptical orbit patterns.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production at this tropical location, though most can be effectively managed with proper planning and installation techniques. Seasonal Rainfall Patterns The most significant challenge comes from the tropical wet season, which typically brings heavy rainfall and increased cloud cover. During these periods, reduced sunlight can temporarily decrease solar panel efficiency. However, the frequent rainfall also provides a natural cleaning benefit, washing away dust and debris that might otherwise accumulate on panel surfaces. High Humidity and Heat The tropical climate brings consistently high humidity levels and elevated temperatures throughout much of the year. Excessive heat can reduce solar panel efficiency, as photovoltaic cells generally perform better in cooler conditions despite needing bright sunlight. Dust and Atmospheric Particles During drier periods, dust accumulation on solar panels can reduce their efficiency by blocking sunlight from reaching the photovoltaic cells. This is particularly relevant during the dry season when natural rainfall cleaning is less frequent.Preventative Measures for Optimal Performance
Several installation and maintenance strategies can help maximize solar energy production despite these environmental challenges:- Install panels with adequate ventilation spacing underneath to promote air circulation and heat dissipation
- Use mounting systems that allow for proper drainage during heavy rainfall periods
- Implement regular cleaning schedules during dry seasons to remove dust buildup
- Consider anti-reflective coatings that can help maintain efficiency in high-humidity conditions
- Install monitoring systems to track performance and identify when cleaning or maintenance is needed
Overall Assessment
Despite these potential challenges, Maravilha's location offers strong potential for solar energy generation throughout the year. The consistent tropical sunlight, combined with reasonable production levels even during the lowest-performing winter season, makes this an attractive location for solar installations. With proper installation techniques and regular maintenance practices, the environmental factors can be effectively managed to ensure optimal energy production year-round.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 Maravilha, Alagoas
Seasonal solar PV output for Latitude: -9.2256, Longitude: -37.3762 (Maravilha, Alagoas, 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 8° North in Maravilha, Alagoas, Brazil
To maximize your solar PV system's energy output in Maravilha, Alagoas, Brazil (Lat/Long -9.2256, -37.3762) throughout the year, you should tilt your panels at an angle of 8° 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 Maravilha, Alagoas, 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 Maravilha, Alagoas, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 15° North in Autumn | 25° North in Winter | 3° 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.

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 Maravilha, Alagoas, Brazil
Topographical Features of the Maravilha Region
The area surrounding Maravilha in Brazil's Alagoas state is characterized by gently rolling terrain typical of the coastal plains and transition zones of northeastern Brazil. This region sits within the broader Atlantic Forest biome transition area, where the landscape gradually shifts from coastal lowlands toward the interior plateau regions. The topography consists primarily of low hills and shallow valleys, with elevations generally ranging from moderate coastal plain levels to slightly higher inland areas. The terrain around Maravilha features relatively gentle slopes and undulating countryside, making it part of the broader sedimentary basin that extends across much of northeastern Brazil. This geological foundation has created a landscape of soft contours rather than dramatic elevation changes, with occasional small escarpments and ridgelines breaking up the otherwise moderate relief. The area benefits from stable geological conditions, with minimal seismic activity and well-consolidated soils that provide good foundation conditions for infrastructure development.Drainage and Land Use Patterns
The region's drainage system consists of several small to medium-sized watercourses that flow generally eastward toward the Atlantic Ocean. These waterways have carved shallow valleys through the landscape, creating a dendritic pattern of drainage that influences local topography. The interfluves between these drainage systems offer relatively flat to gently sloping areas that remain well-drained throughout most of the year. Agricultural land use dominates much of the surrounding area, with a mix of crop cultivation and pastoral activities taking advantage of the moderate terrain. This existing land use pattern has resulted in cleared areas with good accessibility via rural road networks, though the specific suitability of any given area would depend on current land ownership and agricultural productivity considerations.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations in the Maravilha area would be found on the broader interfluves and gentle ridgelines that offer several key advantages. These elevated areas between the main drainage valleys provide excellent natural drainage, reducing concerns about seasonal flooding or water accumulation that could affect solar infrastructure. The moderate slopes in these areas, typically less than five percent gradient, offer ideal conditions for solar panel installation while allowing for proper drainage and maintenance access. Areas to the west and northwest of Maravilha appear particularly promising, where the terrain opens up into broader, more gently undulating countryside. These locations benefit from good exposure to prevailing weather patterns while maintaining the stable geological conditions necessary for large-scale infrastructure. The slightly elevated positions also provide natural advantages for electrical transmission connections, as power lines can follow ridgeline routes more easily than crossing multiple drainage valleys. The eastern approaches toward the coast, while flatter in some areas, may present challenges related to higher humidity, salt air exposure, and potentially more complex drainage requirements. However, some of these coastal plain areas could still prove viable, particularly where they offer large contiguous tracts of suitable land with good transportation access.Infrastructure and Access Considerations
The topographical advantages of the Maravilha region extend beyond simple terrain suitability to include practical infrastructure considerations. The moderate relief allows for relatively straightforward road construction and maintenance access to potential solar installations. The existing network of rural roads generally follows the natural contours of the land, connecting the higher ground between drainage systems. The geological stability of the region, combined with the well-drained soils found on the interfluves, creates favorable conditions for the foundations and support structures required for large solar arrays. The absence of extreme topographical features means that site preparation costs would likely remain moderate, while the gentle terrain allows for efficient layout of solar panels to maximize land use while maintaining proper spacing and orientation.Brazil solar PV Stats as a country
