Jatobá, Brazil presents an excellent location for year-round solar PV energy generation. Located in the tropical region at coordinates -5.8623, -44.2692, this area benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods rather than significant temperature variations.

Solar Energy Production Potential

The solar energy output data for Jatobá demonstrates strong and consistent performance across all seasons. Winter provides the highest energy generation at 6.32 kWh per day per kW of installed solar capacity, followed closely by spring at 5.96 kWh/day. Autumn delivers 5.84 kWh/day, while summer produces 5.17 kWh/day per kW installed. This seasonal pattern is typical for tropical locations in the Southern Hemisphere, where winter months often provide optimal solar conditions due to clearer skies and the sun's position relative to the location. The relatively small variation between seasons (approximately 1.15 kWh difference between the highest and lowest production periods) indicates reliable year-round solar generation potential. For maximum energy production from a fixed solar panel installation at this location, panels should be tilted at 7 degrees facing north. This optimal angle is calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance data to maximize total annual output.

Environmental and Weather Factors

Several environmental factors in Jatobá could potentially impact solar energy production:

• Seasonal rainfall patterns: The tropical climate brings distinct wet and dry seasons, with heavy rainfall during wet periods potentially reducing solar irradiance through cloud cover
• High humidity levels: Tropical locations typically experience elevated humidity, which can affect panel efficiency and promote faster accumulation of dust and debris
• Dust and particulate matter: Dry season conditions may increase airborne dust that settles on solar panels, reducing their efficiency
• Vegetation growth: The tropical climate supports rapid plant growth, which could create shading issues if not properly managed

Preventative Measures for Optimal Performance

To ensure maximum energy production despite these environmental challenges, several preventative measures should be implemented: Regular cleaning schedules are essential, particularly during and after the dry season when dust accumulation is highest. Installing panels with adequate spacing and ventilation helps manage humidity-related issues and prevents moisture buildup that could affect electrical components. Proper site preparation and ongoing vegetation management around the solar installation prevents shading from rapidly growing tropical plants. This includes regular trimming of nearby trees and bushes that could cast shadows on the panels. Using high-quality mounting systems and electrical components rated for tropical conditions helps ensure long-term reliability in the humid environment. Anti-corrosion treatments and weatherproof sealing are particularly important in this climate. Installing monitoring systems allows for quick identification of performance issues, enabling prompt maintenance responses. This is especially valuable during the wet season when access for routine inspections might be more challenging. Despite these considerations, Jatobá's consistent solar output throughout the year makes it a highly suitable location for solar PV installations, with proper planning and maintenance ensuring optimal energy generation.

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 Jatobá, Maranhão

Seasonal solar PV output for Latitude: -5.8623, Longitude: -44.2692 (Jatobá, Maranhão, 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 7° North in Jatobá, Maranhão, Brazil

To maximize your solar PV system's energy output in Jatobá, Maranhão, Brazil (Lat/Long -5.8623, -44.2692) throughout the year, you should tilt your panels at an angle of 7° 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 Jatobá, Maranhão, 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 Jatobá, Maranhão, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
10° South in Summer	13° North in Autumn	21° North in Winter	0° 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 Jatobá, Maranhão, 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 Jatobá, Maranhão, 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 Jatobá, Maranhão, Brazil

Topographical Features of the Jatobá Region

The area surrounding Jatobá in northeastern Brazil sits within the Caatinga biome, characterized by relatively flat to gently rolling terrain typical of the interior Pernambuco state. The landscape consists primarily of low-lying plains and plateaus with elevations ranging from approximately 200 to 400 meters above sea level. These modest elevations create a predominantly level topography that extends across much of the region, interrupted occasionally by small hills and rocky outcroppings. The terrain features scattered mesas and low ridges that rise gradually from the surrounding plains. These elevated areas are often composed of sedimentary rock formations that have resisted erosion over time. Between these higher points, broad valleys and depressions collect seasonal rainfall, creating temporary wetlands during the rainy season before drying out completely during extended dry periods. Rocky surfaces and exposed bedrock are common throughout the region, with thin soils covering much of the landscape. The natural vegetation consists of drought-resistant shrubs, cacti, and small trees adapted to the semi-arid climate. This sparse vegetation cover means that much of the underlying terrain remains visible and accessible.

Drainage Patterns and Water Features

The regional drainage system consists mainly of intermittent streams and seasonal watercourses that flow only during periods of significant rainfall. These temporary waterways carve shallow channels through the landscape, creating minor undulations in an otherwise relatively flat terrain. Permanent water sources are scarce, with most surface water disappearing during the dry season. Small reservoirs and artificial ponds dot the landscape where local communities have constructed earthen dams to capture and store rainwater. These water retention structures create localized variations in the topography but generally occupy low-lying areas that follow natural drainage patterns.

Optimal Areas for Large-Scale Solar Development

The extensive flat and gently sloping areas south and southeast of Jatobá present ideal conditions for large-scale solar photovoltaic installations. These zones offer vast stretches of relatively level ground with minimal topographical obstacles, allowing for efficient panel placement and maintenance access. The sparse vegetation and thin soils in these areas would require minimal clearing and preparation work. The elevated plateau areas to the northeast of the town also show strong potential for solar development. While slightly higher in elevation, these locations maintain gentle gradients suitable for solar arrays while potentially offering improved drainage characteristics. The rocky substrate in these areas provides stable foundations for mounting systems. Areas immediately adjacent to existing infrastructure corridors would be particularly advantageous for solar development, as they already benefit from established access roads and proximity to electrical transmission networks. The relatively uniform topography throughout much of the region means that developers would have multiple viable site options, allowing them to select locations that best balance factors such as land availability, grid connectivity, and environmental considerations. The minimal topographical variation across much of the surrounding landscape means that large installations could be developed with standardized mounting systems and consistent panel orientations, potentially reducing both construction costs and ongoing maintenance requirements.
