Marituba, Pará, Brazil is an excellent location for year-round solar energy generation, benefiting from its tropical position where sunlight remains consistent throughout the year and weather patterns follow wet and dry seasons rather than traditional temperature-based seasons.

Solar Energy Output Performance

The solar energy production data for Marituba shows impressive and consistent performance across all seasons. During summer, solar panels generate 5.07 kWh per day for each kW of installed capacity. This increases to 5.42 kWh/day in autumn, peaks at 5.97 kWh/day in winter, and reaches its highest output of 6.16 kWh/day in spring. The location demonstrates excellent solar potential with spring being the optimal time for solar generation, followed closely by winter. Even the lowest-performing season (summer) still delivers strong energy output, making this location highly suitable for consistent year-round solar power generation.

Optimal Panel Installation

For fixed solar panel installations in Marituba, Pará, the ideal tilt angle is 2 degrees North. This extremely shallow angle maximizes total year-round solar production and reflects the location's proximity to the equator, where the sun travels nearly overhead throughout the year.

Environmental and Weather Challenges

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

• Heavy tropical rainfall: The wet season brings intense downpours that can reduce solar irradiance and create cloud cover
• High humidity: Persistent moisture in the air can create haze and reduce solar panel efficiency
• Dust and debris accumulation: Dry periods may lead to dust buildup on panels, while wet seasons can deposit organic matter
• Vegetation growth: The tropical climate promotes rapid plant growth that could create shading issues

Preventative Measures for Better Performance

To ensure optimal solar energy production despite these challenges, several installation strategies should be considered:

• Regular cleaning systems: Install automated washing systems or schedule frequent manual cleaning to remove dust, debris, and organic deposits
• Proper drainage: Ensure excellent drainage around solar installations to prevent water pooling and reduce humidity-related issues
• Vegetation management: Maintain clear zones around solar arrays and regularly trim nearby vegetation to prevent shading
• Quality mounting systems: Use corrosion-resistant materials designed for tropical climates to withstand high humidity and rainfall
• Ventilation spacing: Allow adequate airflow beneath panels to reduce heat buildup and improve efficiency in the tropical climate

Despite these considerations, Marituba's consistent high solar output throughout the year makes it an ideal location for solar energy projects, with proper installation and maintenance practices ensuring optimal performance.

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 Marituba

Seasonal solar PV output for Latitude: -1.3731, Longitude: -48.3142 (Marituba, 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 2° North in Marituba, Brazil

To maximize your solar PV system's energy output in Marituba, Brazil (Lat/Long -1.3731, -48.3142) throughout the year, you should tilt your panels at an angle of 2° 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 Marituba, 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 Marituba, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 2° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
15° South in Summer	8° North in Autumn	17° North in Winter	5° South 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 Marituba, 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 Marituba, 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 Marituba, Brazil

Topographical Features Around Marituba

Marituba sits within the expansive Amazon Basin in the northern Brazilian state of Pará, positioned just southeast of the state capital Belém. The topography in this region is characterized by remarkably flat terrain, with elevations rarely exceeding 50 meters above sea level. This low-lying landscape forms part of the vast alluvial plains that define much of the eastern Amazon region, where countless rivers have deposited sediments over millennia to create an essentially level surface.

The area features a complex network of waterways, including numerous small rivers, streams, and seasonal wetlands that drain toward the mighty Amazon River system. These water bodies create a mosaic of slightly elevated ridges and lower-lying areas that flood during the wet season. The terrain undulates very gently, with subtle rises and depressions that are often imperceptible to the casual observer but play crucial roles in local drainage patterns.

Dense tropical rainforest originally covered this entire region, though significant portions around Marituba have been cleared for urban development, agriculture, and pastureland. The remaining forested areas display the typical characteristics of Amazon lowland forest, with towering canopy trees rising 30-40 meters above the ground. Where deforestation has occurred, the landscape opens up to reveal the underlying gentle topography more clearly.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be found on the slightly elevated ridge areas that remain dry throughout the year. These higher portions of the landscape, though only marginally above the surrounding terrain, provide essential drainage and avoid the seasonal flooding that affects lower-lying zones. Such elevated areas can be identified southeast and southwest of Marituba, where the land rises almost imperceptibly toward the interior.

Already-cleared agricultural lands and cattle pastures present the most immediate opportunities for solar development, as they require minimal additional clearing and typically occupy the better-drained soils on these gentle rises. These areas often extend for several square kilometers in continuous blocks, providing the space necessary for utility-scale solar farms. The existing road infrastructure serving these agricultural areas would also facilitate construction and maintenance access.

Areas to avoid would include the numerous wetlands and seasonally flooded zones that characterize much of the local landscape. These lower-lying areas, while appearing suitable during the dry season, become waterlogged or completely inundated during peak rainfall periods. Additionally, any remaining primary forest areas would be environmentally unsuitable for development due to their ecological value and the complex permitting requirements associated with Amazon deforestation.

The relatively stable clay and sandy clay soils found on the elevated areas provide adequate foundation conditions for solar mounting systems, though proper geotechnical analysis would be essential for any specific site. The minimal topographical variation across potential sites would simplify installation logistics and reduce grading requirements, making development more cost-effective compared to hillier regions.
