Campo Alegre, Alagoas, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical positioning where consistent sunlight is available throughout most of the year and seasons are characterized more by wet and dry periods rather than significant temperature variations.
Solar Energy Production Performance
The solar energy output data for Campo Alegre demonstrates strong performance across all seasons. Spring emerges as the peak production period, generating 7.02 kWh per day per kW of installed solar capacity. Summer follows closely with 6.86 kWh/day per kW, making these two seasons the optimal times for solar energy generation at this location. Autumn production drops to 5.67 kWh/day per kW, while winter shows the lowest output at 4.87 kWh/day per kW. However, even the winter production levels remain quite respectable for solar energy generation, indicating that this location maintains viable solar potential throughout the entire year.Optimal Panel Installation
For maximum year-round solar production at Campo Alegre, Alagoas, solar panels should be installed at a fixed tilt angle of 8 degrees facing North. This angle has been calculated to optimize total annual energy output by accounting for the sun's path throughout the year, daily solar elevation angles, and weighting these factors against actual solar irradiance data for the location.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production at Campo Alegre and require attention during installation planning. The tropical climate brings distinct wet and dry seasons, with the wet season potentially reducing solar output due to increased cloud cover and frequent rainfall. The high humidity levels common in tropical regions can also affect panel efficiency and may accelerate corrosion of electrical components if not properly protected. Dust accumulation presents another challenge, particularly during drier periods when airborne particles can settle on panel surfaces and reduce their effectiveness. The tropical environment may also support vegetation growth that could create shading issues if not properly managed around solar installations.Preventative Measures for Optimal Performance
Several installation strategies can help maximize solar energy production despite these environmental challenges:- Install panels with adequate drainage systems and slight tilting to prevent water accumulation during heavy rains
- Use corrosion-resistant mounting hardware and electrical components rated for high-humidity tropical environments
- Implement regular cleaning schedules to remove dust and debris, with more frequent cleaning during dry seasons
- Ensure proper ventilation around panels to prevent overheating in the tropical climate
- Maintain clear vegetation management around the installation site to prevent shading from growing plants
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 Campo Alegre
Seasonal solar PV output for Latitude: -9.7909, Longitude: -36.2834 (Campo Alegre, 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 Campo Alegre, Brazil
To maximize your solar PV system's energy output in Campo Alegre, Brazil (Lat/Long -9.7909, -36.2834) 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 Campo Alegre, 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 Campo Alegre, 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 |
|---|---|---|---|
| 6° 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 determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Campo Alegre, Brazil
Topographical Features of Campo Alegre
Campo Alegre sits within the northeastern Brazilian state of Alagoas, positioned in a region characterized by gently rolling terrain and relatively modest elevation changes. The landscape around this municipality features a mix of low hills and flat to undulating plains that are typical of the coastal interior zone of the Northeast region. The area lies within the transition zone between the Atlantic coastal lowlands and the more elevated Borborema Plateau that extends across much of northeastern Brazil. The immediate vicinity of Campo Alegre displays a predominantly flat to gently sloping topography, with elevations generally ranging from approximately 200 to 400 meters above sea level. This moderate relief creates favorable conditions for development and infrastructure, as the terrain is neither too steep for construction nor plagued by significant drainage issues that might complicate large-scale installations.Drainage and Water Features
The region's drainage pattern is influenced by several small to medium-sized tributaries that flow toward larger river systems. These waterways have carved shallow valleys through the landscape over time, creating a subtle but noticeable undulation across the terrain. The presence of seasonal streams and intermittent water courses reflects the semi-arid climate characteristics of this part of Alagoas, where precipitation patterns create periods of both water abundance and scarcity throughout the year. The soil composition in the area consists primarily of sedimentary deposits with some areas of weathered crystalline rocks, creating a stable foundation that can support substantial infrastructure development. The relatively porous nature of much of the local soil provides adequate drainage during wet periods while maintaining structural integrity during dry seasons.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations around Campo Alegre would be the expansive flat to gently rolling areas that extend primarily to the south and southwest of the municipality. These zones offer several advantages including minimal slope variations that reduce grading costs, adequate accessibility for construction equipment and maintenance vehicles, and sufficient distance from populated areas to minimize land use conflicts. The elevated plateaus and mesa-like formations found approximately 15 to 25 kilometers southeast of Campo Alegre present particularly attractive opportunities for solar development. These areas combine favorable topographical conditions with reduced competition from agricultural activities, as the terrain and soil conditions are less suitable for intensive farming compared to the more fertile valleys closer to water sources. Areas with gentle south-facing slopes would be especially valuable for solar installations, as they can be oriented to maximize solar exposure throughout the day. The region's topography includes numerous such locations where natural land contours could be leveraged to optimize panel positioning without requiring extensive earthwork or grading operations.Infrastructure and Access Considerations
The transportation network around Campo Alegre includes several paved and unpaved roads that connect to larger regional highways, providing reasonable access to potential solar development sites. The relatively flat terrain means that extending existing road networks to reach optimal installation sites would be technically feasible and economically viable for large-scale projects. Areas located within 10 to 20 kilometers of existing electrical transmission infrastructure would offer the most practical advantages for solar development, as connection costs represent a significant portion of project economics. The topography between Campo Alegre and these potential sites generally presents minimal obstacles for transmission line construction, with few significant elevation changes or natural barriers that would complicate electrical infrastructure development. The combination of suitable terrain, reasonable accessibility, and proximity to existing infrastructure makes the broader Campo Alegre region well-positioned for substantial solar energy development, particularly in the flatter agricultural transition zones where land acquisition costs may be more favorable than in areas with higher agricultural productivity.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed.
