Xinguara, Pará, Brazil, situated at latitude -6.8537 and longitude -49.4635, offers a promising location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.

Seasonal Solar Performance

The solar energy potential in Xinguara remains relatively stable across all seasons, with some variations: Winter stands out as the most productive season, yielding an impressive 6.36 kWh per day for each kilowatt of installed solar capacity. This peak performance during the cooler months is likely due to clearer skies and lower temperatures, which enhance solar panel efficiency. Spring and autumn show similar outputs, with 5.51 kWh/day and 5.48 kWh/day respectively. These transitional seasons maintain a strong solar generation potential, demonstrating the location's year-round suitability for solar power. Summer, surprisingly, has the lowest output at 5.04 kWh/day. This slight dip might be attributed to increased cloud cover or higher temperatures, which can marginally reduce panel efficiency.

Optimal Panel Installation

For fixed solar panel installations in Xinguara, Pará, the ideal tilt angle to maximize year-round energy production is 8 degrees facing North. This relatively shallow angle reflects the location's proximity to the equator, where the sun's path stays closer to directly overhead throughout the year.

Environmental Considerations

While Xinguara's climate is generally favorable for solar energy production, there are a few factors to consider: 1. High humidity: The tropical climate can lead to increased moisture, potentially affecting electrical components. 2. Heavy rainfall: During the wet season, frequent rain may temporarily reduce solar output. To mitigate these issues, installers should use weather-resistant equipment, ensure proper sealing of all components, and implement effective drainage systems. Regular maintenance and cleaning of panels will also help maintain optimal performance. In conclusion, Xinguara presents an excellent location for solar PV installations, with consistent and substantial energy generation potential throughout the year. The minor seasonal variations and environmental factors can be easily managed with proper planning and maintenance, making it an ideal site for sustainable energy production.

Solar output per kW of installed solar PV by season in Xinguara

Seasonal solar PV output for Latitude: -6.8537, Longitude: -49.4635 (Xinguara, 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 Xinguara, Brazil

To maximize your solar PV system's energy output in Xinguara, Brazil (Lat/Long -6.8537, -49.4635) 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 Xinguara, 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 Xinguara, 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
9° South in Summer	14° North in Autumn	23° North in Winter	1° 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.

Calculate solar panel row spacing in Xinguara, 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 Xinguara, 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 Xinguara, Brazil

The topography around Xinguara, Brazil is characterized by a mix of gently rolling hills and flat plains typical of the southeastern Amazon region. This area is part of the Brazilian Shield, an ancient geological formation that has been weathered over millions of years. The landscape is predominantly covered by tropical savanna, known locally as "cerrado," interspersed with patches of rainforest.

The terrain in this region is generally low-lying, with elevations ranging from about 200 to 400 meters above sea level. The area is drained by numerous small rivers and streams that are part of the larger Xingu River basin. These waterways have carved shallow valleys into the landscape over time, creating a subtle undulating pattern across the region.

For large-scale solar PV installations, the most suitable areas nearby would be the open, flat expanses of cerrado vegetation. These areas offer several advantages for solar energy development:

1. Abundant sunlight: The region experiences high levels of solar radiation throughout the year, making it ideal for solar power generation.
2. Minimal shading: The relatively sparse vegetation of the cerrado means less natural obstruction to sunlight.
3. Easy access: The gently rolling terrain allows for easier construction and maintenance of solar installations compared to more rugged landscapes.
4. Lower ecological impact: Utilizing already open areas reduces the need for deforestation, which is a significant concern in the Amazon region.

Specifically, the areas to the east and southeast of Xinguara tend to have more open, savanna-like terrain that would be well-suited for solar PV development. These locations offer a good balance of favorable topography, sunlight exposure, and accessibility to existing infrastructure.

However, it's important to note that any large-scale solar development in this region would need to carefully consider environmental impacts, local land use rights, and the potential effects on the delicate Amazon ecosystem. Proper planning and environmental assessments would be crucial to ensure sustainable implementation of solar energy projects in this area.
