Novo Repartimento, Brazil offers excellent conditions for year-round solar energy generation, making it a highly suitable location for solar PV installations. Located in the Amazon region of Pará state, this tropical location benefits from consistent sunlight throughout the year, with seasonal variations driven more by rainfall patterns than temperature changes.

Solar Energy Production Performance

The solar energy output at Novo Repartimento shows strong performance across all seasons, with winter providing the peak generation period. The expected electricity output per kilowatt of installed solar capacity varies seasonally:

• Summer: 4.85 kWh per day per kW installed
• Autumn: 5.38 kWh per day per kW installed
• Winter: 5.89 kWh per day per kW installed
• Spring: 5.39 kWh per day per kW installed

Winter emerges as the ideal time for solar generation, producing approximately 21% more energy than summer. This seasonal pattern is typical for locations in the Southern Hemisphere tropics, where winter months often feature clearer skies and less cloud cover. For optimal year-round energy production, solar panels should be installed at a fixed tilt angle of 6 degrees facing north. This relatively shallow angle maximizes solar collection throughout the year at this near-equatorial latitude.

Environmental and Weather Challenges

Several significant factors in the Amazon region can impact solar energy production and require careful consideration during installation planning. High Humidity and Moisture
The tropical climate brings persistent high humidity levels that can cause corrosion of metal components, degradation of electrical connections, and potential damage to inverters and other electronic equipment. Installing equipment in well-ventilated enclosures with proper sealing and using marine-grade or tropical-rated components can help mitigate these issues. Heavy Rainfall and Wet Season
The region experiences intense rainfall during wet seasons, which can reduce solar output due to cloud cover and physically block sunlight when rain accumulates on panel surfaces. While rain naturally cleans panels, ensuring proper drainage around installations and using panels with good self-cleaning properties helps maintain optimal performance. Vegetation Growth and Shading
The Amazon's rapid plant growth can quickly create shading issues if not properly managed. Regular vegetation maintenance around solar installations is essential, and initial site preparation should include adequate clearance zones to prevent future shading problems. Dust and Organic Debris
Despite frequent rainfall, periods between rains can allow dust, pollen, and organic matter to accumulate on panel surfaces. Installing panels at the recommended 6-degree tilt helps with natural cleaning, while establishing regular maintenance schedules ensures optimal light transmission.

Installation Best Practices

Successful solar installations in this environment require specific protective measures. Using corrosion-resistant mounting systems made from aluminum or stainless steel extends system lifespan. Electrical components should be rated for high-humidity tropical conditions, with proper grounding systems to handle frequent electrical storms common in the Amazon region. Adequate spacing between panel rows prevents moisture accumulation and allows for air circulation, which helps reduce humidity-related problems. Installing monitoring systems enables quick identification of performance issues caused by environmental factors. Overall, while Novo Repartimento presents some environmental challenges typical of Amazon locations, the consistently strong solar resource and year-round generation potential make it an attractive location for solar energy projects when proper installation and maintenance practices are followed.

Solar output per kW of installed solar PV by season in Novo Repartimento

Seasonal solar PV output for Latitude: -4.7003, Longitude: -50.5222 (Novo Repartimento, 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 6° North in Novo Repartimento, Brazil

To maximize your solar PV system's energy output in Novo Repartimento, Brazil (Lat/Long -4.7003, -50.5222) throughout the year, you should tilt your panels at an angle of 6° 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 Novo Repartimento, 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 Novo Repartimento, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
11° South in Summer	11° North in Autumn	20° North in Winter	1° 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 Novo Repartimento, 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 Novo Repartimento, 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 Novo Repartimento, Brazil

Topography of Novo Repartimento Region

Novo Repartimento sits in the southeastern portion of Pará state in Brazil's Amazon region, positioned along the Xingu River valley. The terrain around this municipality is characterized by gently rolling hills and relatively low-lying plains that are typical of the Amazon Basin's transition zones. The landscape exhibits modest elevation changes, with most areas ranging between 100 and 300 meters above sea level.

The topography is dominated by the broad floodplains and terraces associated with the Xingu River system, which creates a network of waterways, wetlands, and seasonally flooded areas throughout the region. These river valleys are interspersed with slightly elevated plateaus and gentle ridges that provide natural drainage divides between different tributary systems.

The region's geology consists primarily of sedimentary formations from the Amazon Basin, creating relatively stable ground conditions with occasional outcrops of older crystalline rocks. The terrain is generally well-drained except in the immediate vicinity of rivers and streams, where seasonal flooding can occur during the wet months.

Vegetation and Land Use Patterns

The natural vegetation transitions from dense Amazon rainforest to areas of cerrado savanna, creating a mosaic landscape. Much of the original forest cover has been modified through agricultural activities, cattle ranching, and selective logging operations. This land use pattern has created a patchwork of cleared areas, secondary forest growth, pastureland, and remaining primary forest fragments.

The cleared agricultural lands tend to be concentrated on the more elevated and well-drained terrain, while forested areas often remain in the lower-lying zones near waterways and in areas with steeper slopes or poorer drainage.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations would be found on the elevated plateaus and gentle ridges that extend between the major river valleys. These areas offer several advantages including stable, well-drained soils that minimize foundation challenges and reduce the risk of seasonal flooding.

Previously cleared agricultural lands and established pasture areas would be particularly well-suited for solar development, as they already lack forest cover and have been demonstrated to support infrastructure development. These locations typically feature relatively flat to gently sloping terrain that would minimize grading requirements and construction costs.

The elevated areas south and east of the main urban center would be especially favorable, as they combine appropriate topographic conditions with proximity to existing road networks and electrical infrastructure. These zones benefit from good drainage characteristics and are positioned away from the primary flood-prone areas along the Xingu River and its major tributaries.

Areas to avoid would include the immediate floodplains of rivers and streams, wetland zones, and any remaining steep-sloped terrain. The low-lying areas near water bodies, while offering flat terrain, present challenges related to seasonal flooding, higher humidity, and potential environmental sensitivities that could complicate large-scale solar installations.
