Solar Energy Potential in Barcarena, Pará, Brazil

Barcarena, Pará, Brazil, located at latitude -1.5466 and longitude -48.6325, offers excellent conditions for solar PV energy generation throughout the year. This tropical location benefits from consistent sunlight patterns that make it highly suitable for solar power investments. The seasonal electricity output from solar PV systems in Barcarena shows remarkable consistency with slight variations throughout the year. During summer, each kilowatt of installed solar capacity produces approximately 5.07 kWh per day. This output increases to 5.42 kWh/day in autumn, rises further to 5.97 kWh/day in winter, and reaches its peak in spring with 6.16 kWh/day. Interestingly, unlike many locations worldwide where summer provides peak solar production, Barcarena experiences its highest solar energy generation during spring, followed closely by winter. This pattern reflects the tropical climate's unique characteristics, where factors beyond simply the sun's height in the sky influence energy production.

Optimal Panel Installation

For those considering solar PV installations in Barcarena, Pará, the ideal tilt angle for fixed solar panels to maximize year-round energy production is 2 degrees facing North. This nearly flat orientation captures the abundant tropical sunlight effectively throughout the year, taking advantage of the sun's path across the sky at this near-equatorial latitude.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Barcarena:
  • Heavy rainfall during the wet season can reduce solar efficiency through cloud cover and direct panel soiling
  • High humidity levels may accelerate component degradation if not properly protected
  • Tropical storms, while not as severe as hurricanes, can occasionally damage installations
  • Dust accumulation during dry seasons can gradually reduce panel efficiency
To mitigate these challenges, several preventative measures are recommended. Installing panels with robust waterproof ratings (minimum IP65) helps protect against moisture damage. Regular cleaning schedules, particularly during dry seasons when dust accumulates, can maintain optimal efficiency. Additionally, implementing proper drainage systems around ground-mounted installations prevents flooding issues during heavy tropical downpours. Despite these considerations, Barcarena's consistent year-round solar radiation makes it an excellent location for solar PV installations, with annual average daily production exceeding 5.65 kWh per installed kilowatt—significantly higher than many non-tropical locations worldwide.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 2° North in Barcarena, Brazil

To maximize your solar PV system's energy output in Barcarena, Brazil (Lat/Long -1.5466, -48.6325) 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 Barcarena, 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 Barcarena, 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
14° South in Summer 8° North in Autumn 17° North in Winter 4° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Barcarena, Brazil as follows: In Summer, set the angle of your panels to 14° facing South. In Autumn, tilt panels to 8° facing North for maximum generation. During Winter, adjust your solar panels to a 17° angle towards the North for optimal energy production. Lastly, in Spring, position your panels at a 4° angle facing South to capture the most solar energy in Barcarena, Brazil.

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.

Topography for solar PV around Barcarena, Brazil

Barcarena is a municipality located in the northern Brazilian state of Pará, situated near the mouth of the Amazon River. The topography of Barcarena is characterized by relatively flat terrain with gentle undulations typical of the Amazon Basin lowlands. The elevation in this region generally ranges from just a few meters above sea level to approximately 30 meters in some areas. This low-lying landscape is interspersed with numerous waterways, including the Pará River to the east and various smaller tributaries and streams that crisscross the region. The natural landscape around Barcarena consists predominantly of tropical rainforest vegetation, though significant portions have been cleared for agriculture, industrial development, and urban expansion. The soil composition is primarily latosols, which are highly weathered, acidic soils common in tropical regions. These soils have undergone extensive leaching due to the abundant rainfall characteristic of the Amazon climate.

Hydrological Features

The hydrological network around Barcarena is extensive and complex. The municipality is bordered by the Pará River to the east, which is part of the larger Amazon River system. Numerous smaller rivers, streams, and seasonal waterways create a dense drainage pattern throughout the area. During the rainy season, some low-lying areas may experience temporary flooding, which is an important consideration for any large-scale development projects in the region.

Climate Considerations

Barcarena experiences a tropical rainforest climate with consistent temperatures throughout the year and distinct wet and dry seasons. The region receives substantial precipitation, with the rainy season typically occurring from December to May. The relatively flat topography does not create significant rain shadow effects, meaning rainfall patterns are fairly consistent across the area.

Suitable Areas for Solar PV Development

When considering areas most suitable for large-scale solar photovoltaic development around Barcarena, several topographical factors come into play. The most appropriate locations would be: Areas of higher elevation that are less prone to flooding represent the most suitable terrain for solar PV installations. These include the slightly elevated plateaus and ridges found primarily in the central and western portions of the municipality. These areas offer better drainage and reduced risk of seasonal inundation that could damage infrastructure. Cleared lands that were previously used for agriculture or other human activities present opportunities for solar development with minimal additional environmental impact. These areas are predominantly located along major roads and around the outskirts of urban centers in the region. The northeastern section of the municipality, which experiences slightly less annual rainfall compared to areas closer to the Amazon River, may offer marginally better conditions for solar energy production. While the difference is not dramatic, even small improvements in solar irradiance can be significant for large-scale operations. Areas with good accessibility via existing road networks would reduce construction costs and ongoing maintenance expenses. The main highways connecting Barcarena to Belém and other nearby municipalities provide potential corridors for solar development.

Topographical Challenges

Despite the potential for solar development, the topography around Barcarena presents several challenges. The high water table and risk of flooding in many areas necessitate careful site selection and possibly elevated mounting systems for solar panels. The predominantly flat terrain, while easy to build on, may require more land area for the same generating capacity compared to regions where panels can be oriented on natural slopes. Additionally, the extensive waterway network means that many potential development sites are fragmented by rivers and streams, potentially limiting the contiguous area available for very large installations. Environmental considerations are also paramount, as the region is part of the ecologically sensitive Amazon Basin, requiring thoughtful planning to minimize habitat disruption.

Brazil solar PV Stats as a country
