Irituia, Pará, Brazil offers an excellent location for solar power generation throughout the year. Situated in the tropical region of northern Brazil, this location benefits from consistent sunlight patterns that make it highly suitable for solar PV installations.

The energy production data reveals impressive solar potential across all seasons. Spring stands out as the most productive period with 6.27kWh per day for each kilowatt installed, closely followed by winter with 6.04kWh/day. The autumn and summer seasons still deliver strong performance at 5.36kWh/day and 5.03kWh/day respectively.

For fixed solar panel installations in Irituia, Pará, the ideal tilt angle is 2 degrees North. This slight tilt optimizes year-round energy capture by accounting for the location's proximity to the equator, maximizing the total annual solar production.

Environmental and Weather Considerations

Despite Irituia's excellent solar potential, several environmental factors could affect solar production. The most significant challenge is the high rainfall during the wet season, typical of tropical regions. Heavy cloud cover during these periods can temporarily reduce solar energy generation.

Another consideration is dust and debris accumulation, which is common in rural tropical areas. Regular rainfall helps with natural cleaning, but during dry periods, dust buildup can gradually reduce panel efficiency.

High humidity levels in this tropical location may accelerate degradation of certain system components if not properly protected. Additionally, potential vegetation growth can create shading issues if not managed properly.

Preventative Measures

To maximize solar production in Irituia, Pará, several practical measures can be implemented:

• Install panels with high humidity and corrosion resistance ratings specifically designed for tropical environments
• Implement regular cleaning schedules during dry periods when natural rainfall cleaning is less frequent
• Use microinverters or power optimizers to minimize the impact of partial shading from clouds or vegetation
• Maintain adequate clearance around the installation to prevent vegetation overgrowth
• Consider slight overprovisioning of the system to compensate for reduced output during the rainier months

With these preventative measures in place, a solar PV system in Irituia can capitalize on the location's excellent year-round solar potential, particularly taking advantage of the peak production periods in spring and winter.

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 Irituia

Seasonal solar PV output for Latitude: -1.767, Longitude: -47.4204 (Irituia, 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 Irituia, Brazil

To maximize your solar PV system's energy output in Irituia, Brazil (Lat/Long -1.767, -47.4204) 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 Irituia, 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 Irituia, 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	9° North in Autumn	17° North in Winter	4° 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 Irituia, 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 Irituia, 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 Irituia, Brazil

The topography surrounding Irituia, Brazil presents a diverse landscape characteristic of the eastern Amazon region. Located in the state of Pará, Irituia sits in a predominantly flat to gently undulating terrain with moderate variations in elevation. The area features a mix of low-lying plains interspersed with subtle hills and shallow valleys, creating a rolling landscape that gradually changes as one moves away from the town center. The region is part of the larger Amazon Basin, with the topography being shaped by numerous small rivers and streams that form a complex hydrological network. These waterways have carved shallow valleys throughout the landscape, creating natural drainage systems that flow predominantly toward the larger river systems in the region. The Irituia River itself is a significant geographical feature that influences the local topography.

Vegetation and Land Cover

The natural vegetation around Irituia consists of a transition between dense tropical rainforest and more open forest formations. However, much of the original forest cover has been altered through human activities, with significant portions converted to agricultural land, pastures, and secondary forest growth. This mosaic of different land uses creates a patchwork appearance when viewed from above. The soil composition varies throughout the region but generally consists of weathered, nutrient-poor soils typical of tropical environments, with areas of more fertile alluvial soils along river valleys. These soil characteristics, combined with the topographical features, influence land use patterns and potential development opportunities.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic (PV) installations, the most suitable areas near Irituia would be the cleared, relatively flat lands that have already been modified from their natural state. These areas offer several advantages for solar development: The gently undulating plains to the east and southeast of Irituia present particularly favorable conditions for solar PV deployment. These locations feature minimal slope angles, reducing the costs associated with land preparation and maximizing the efficiency of panel placement. The reduced vegetation in these areas also means less clearing would be required before installation. Elevated plateaus and higher ground that exist in patches throughout the region would provide excellent exposure to sunlight throughout the day. These slightly elevated areas typically experience less flooding during the rainy season, which is an important consideration for infrastructure stability and maintenance access. Former agricultural lands or pastures represent another opportunity for solar development. These areas have already been cleared of dense vegetation and often have existing access roads, reducing the environmental impact and development costs of new solar installations.

Topographical Challenges

Despite the generally favorable conditions, certain topographical features present challenges for solar development around Irituia. The numerous small streams and seasonal waterways create natural divisions in the landscape that would need to be accounted for in site planning. During the rainy season, low-lying areas may experience temporary flooding, making them less suitable for permanent infrastructure. Areas with remaining dense forest cover would require significant clearing, raising both environmental concerns and development costs. The environmental services provided by these forested areas, including carbon sequestration and biodiversity support, would need to be carefully weighed against the benefits of renewable energy development. The optimal approach would likely involve targeting already-disturbed lands with good solar exposure, relatively flat terrain, and proximity to existing roads and transmission infrastructure. This strategy would minimize both environmental impacts and development costs while maximizing the potential for successful large-scale solar energy production.
