Salvaterra, Pará, Brazil represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropical region near the equator, this area benefits from consistent sunlight throughout the year, with seasonal variations characterized more by wet and dry periods rather than the dramatic temperature changes seen in temperate climates.

Solar Energy Production Potential

The solar energy output data for Salvaterra demonstrates strong and consistent performance across all seasons. The location produces between 4.92 and 6.68 kWh per day for each kilowatt of installed solar capacity, which represents excellent productivity for solar installations. Spring emerges as the peak season for solar generation, producing 6.68 kWh/day per kW of installed capacity. Winter follows closely as the second-best performing season at 6.04 kWh/day per kW. Summer generates 5.12 kWh/day per kW, while autumn shows the lowest output at 4.92 kWh/day per kW, though this still represents strong solar production.

Optimal Panel Configuration

For maximum year-round energy production at Salvaterra, Pará, solar panels should be installed at a fixed tilt angle of 1 degree facing north. This nearly flat configuration takes advantage of the location's proximity to the equator, where the sun passes almost directly overhead throughout the year.

Environmental and Weather Challenges

Several local factors could potentially impact solar energy production in Salvaterra and require careful consideration during installation:

• Heavy tropical rainfall: The wet season brings intense precipitation that can reduce solar irradiance and create challenges for equipment maintenance
• High humidity levels: Persistent moisture in the air can affect panel efficiency and accelerate corrosion of metal components
• Dust and debris accumulation: During dry periods, dust buildup on panels can significantly reduce energy output
• Extreme heat: High ambient temperatures can reduce photovoltaic cell efficiency

Preventative Measures for Optimal Performance

To maximize solar energy production despite these environmental challenges, several installation strategies should be implemented: Proper drainage systems around solar installations prevent water accumulation that could damage equipment or create safety hazards. Elevated mounting systems allow air circulation beneath panels, helping to reduce operating temperatures and improve efficiency. Regular cleaning schedules become essential, particularly during dry seasons when dust accumulation peaks. Installing panels with adequate spacing facilitates maintenance access and promotes better airflow for cooling. Equipment selection should prioritize components specifically rated for tropical climates, including corrosion-resistant mounting hardware and electrical connections designed to withstand high humidity. Protective coatings on metal components extend equipment lifespan in the humid environment. Vegetation management around installations prevents shading from rapidly growing tropical plants while maintaining some natural windbreaks that can reduce dust exposure during dry periods. Despite these environmental considerations, Salvaterra's consistent solar resource and strong year-round production potential make it highly suitable for solar photovoltaic installations when proper planning and maintenance practices are implemented.

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 Salvaterra

Seasonal solar PV output for Latitude: -0.7851, Longitude: -48.6217 (Salvaterra, 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 1° North in Salvaterra, Brazil

To maximize your solar PV system's energy output in Salvaterra, Brazil (Lat/Long -0.7851, -48.6217) throughout the year, you should tilt your panels at an angle of 1° 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 Salvaterra, 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 Salvaterra, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 1° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° South in Summer	8° North in Autumn	16° 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 Salvaterra, 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 Salvaterra, 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 Salvaterra, Brazil

Topography of Salvaterra, Brazil

Salvaterra is situated on Marajó Island in the state of Pará, Brazil, positioned in the Amazon River delta region near the Atlantic coast. The topography around Salvaterra is characterized by remarkably flat terrain with minimal elevation changes, typical of the expansive floodplains that dominate this part of the Amazon basin. The landscape consists primarily of low-lying areas that rarely exceed 20 meters above sea level, creating a gently undulating plain that stretches across much of Marajó Island. The region features a complex network of rivers, streams, and seasonal wetlands that create a mosaic of water bodies interspersed with slightly elevated patches of land. During the wet season, significant portions of the surrounding area experience flooding, as the Amazon River system and its tributaries overflow their banks. This seasonal inundation shapes the local topography, creating natural levees along waterways and leaving behind fertile alluvial deposits when the waters recede. The terrain is predominantly composed of sedimentary formations deposited over millennia by the Amazon River system. These deposits have created a relatively uniform landscape with gentle slopes and broad, flat expanses. The soil composition varies from sandy loams on higher ground to clay-rich sediments in lower-lying areas that retain water for extended periods.

Suitable Areas for Large-Scale Solar PV Development

The most appropriate locations for large-scale solar photovoltaic installations around Salvaterra would be the elevated areas that remain above the seasonal flood line. These higher ground locations, though still relatively low in absolute elevation, provide the stability and accessibility necessary for major infrastructure projects. The areas immediately surrounding the town of Salvaterra itself offer some of the most promising sites, as they benefit from existing road access and electrical infrastructure. The eastern and southeastern portions of Marajó Island present particularly favorable conditions for solar development. These areas feature more consistent elevation above flood levels and have better drainage characteristics compared to the western wetland areas. The terrain in these zones is sufficiently flat to minimize grading requirements while avoiding the seasonal flooding that affects lower elevations. Areas near the BR-365 highway corridor and other established transportation routes would be especially well-suited for solar installations due to their accessibility for construction equipment and maintenance operations. The relatively stable ground conditions in these locations, combined with their distance from major waterways, reduce the risk of seasonal flooding that could damage solar infrastructure. The northern coastal areas of the island also present opportunities for solar development, particularly where the terrain rises slightly above the immediate floodplain. These locations benefit from consistent elevation and often feature more consolidated soils that can better support the foundations required for large solar arrays. The proximity to existing settlements and infrastructure in these areas would facilitate grid connection and ongoing maintenance activities.
