Peixe, Tocantins, Brazil presents an excellent location for year-round solar energy generation through photovoltaic panels. Located in the tropical region at coordinates -11.997, -48.5296, this area benefits from consistent sunlight throughout most of the year, with seasonal variations typically defined by wet and dry periods rather than significant changes in solar availability.

Solar Energy Production Potential

The solar energy output data for Peixe demonstrates strong and consistent performance across all seasons. During summer months, solar panels can be expected to generate 5.36 kWh per day for each kW of installed capacity. Production increases notably in autumn to 5.95 kWh/day per kW, reaching its peak during winter at 6.38 kWh/day per kW. Spring maintains strong output at 6.06 kWh/day per kW. Winter emerges as the most productive season for solar generation at this location, followed closely by spring and autumn. Even summer, the lowest-producing season, still delivers substantial energy output, making this location highly suitable for consistent year-round solar power generation. For optimal performance, fixed solar panel installations at Peixe should be tilted at 13 degrees toward the north. This angle has been calculated to maximize total annual solar energy production by accounting for the sun's path throughout the year, Earth's orbital variations, and local solar irradiance patterns.

Environmental and Weather Considerations

Several local factors could potentially impact solar energy production in Peixe and require consideration during installation planning. The tropical climate brings significant rainfall during wet seasons, which can reduce solar panel efficiency through cloud cover and accumulated debris on panel surfaces. Heavy rains may also cause temporary flooding in low-lying areas, potentially affecting ground-mounted installations or electrical components. High humidity levels common in tropical regions can accelerate corrosion of metal components and electrical connections. The combination of heat and moisture creates challenging conditions for electronic inverters and other system components. Dust accumulation during dry periods can significantly reduce panel efficiency, as the fine particles common in this region of Brazil can create a film that blocks sunlight from reaching solar cells.

Preventative Installation Measures

Several installation strategies can help maximize solar energy production despite these environmental challenges:

• Install panels with adequate drainage and self-cleaning angles to allow rainwater to wash away dust and debris naturally
• Use corrosion-resistant materials and protective coatings for all metal components, particularly aluminum frames and mounting hardware
• Ensure proper ventilation around panels and electrical components to manage heat buildup and moisture accumulation
• Select inverters and electrical equipment rated for high-humidity tropical environments with appropriate IP ratings
• Establish regular cleaning and maintenance schedules, particularly during dry seasons when dust accumulation is highest

Elevating installations above potential flood levels and ensuring robust grounding systems will provide additional protection against weather-related damage. With proper installation techniques and regular maintenance, Peixe's excellent solar resource can be effectively harnessed for reliable renewable energy generation throughout the year.

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 Peixe

Seasonal solar PV output for Latitude: -11.997, Longitude: -48.5296 (Peixe, 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 13° North in Peixe, Brazil

To maximize your solar PV system's energy output in Peixe, Brazil (Lat/Long -11.997, -48.5296) throughout the year, you should tilt your panels at an angle of 13° 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 Peixe, 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 Peixe, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° South in Summer	19° North in Autumn	27° North in Winter	6° 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 Peixe, 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 Peixe, 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 Peixe, Brazil

Topography Around Peixe, Brazil

Peixe is located in the state of Tocantins in central Brazil, positioned within the vast Brazilian Cerrado savanna region. The topography around this area is characterized by gently rolling plains and plateaus that form part of the Central Brazilian Plateau. The landscape consists primarily of flat to moderately undulating terrain, with elevation changes that are generally gradual rather than steep.

The region sits at a moderate elevation above sea level, contributing to its relatively stable climate patterns. The terrain is dominated by expansive grasslands interspersed with gallery forests along waterways and scattered patches of cerrado woodland. The soil composition varies from sandy to clay-rich areas, with lateritic soils being common throughout the region due to the tropical climate and geological history.

Water features in the area include several seasonal streams and small rivers that flow toward the Tocantins River system. These waterways create subtle valleys and depressions in the otherwise predominantly flat landscape. The drainage patterns are well-established, with most water flowing in a generally northward direction toward the Amazon basin.

Optimal Areas for Large-Scale Solar PV Development

The relatively flat terrain surrounding Peixe presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas would be the extensive flat plains that stretch in multiple directions from the town center. These areas offer minimal grading requirements and would allow for efficient installation of solar arrays with consistent orientation and spacing.

The plateaus to the south and east of Peixe are particularly well-suited for solar development due to their stable ground conditions and minimal vegetation density. These elevated flat areas provide good drainage, reducing concerns about flooding during the rainy season, while their open nature minimizes shading issues that could affect panel performance.

Areas with sandy or well-drained lateritic soils would be preferable for solar installations, as they provide stable foundations while avoiding the complications that might arise from clay-heavy soils during wet periods. The gentle slopes found in some areas could actually be beneficial for solar installations, as they can provide natural drainage and potentially optimal panel angles without requiring extensive earthwork.

The proximity to existing infrastructure, including roads and power transmission lines, makes certain areas more economically viable for development. Locations within reasonable distance of Peixe itself would benefit from easier access for construction and maintenance activities, while areas near existing electrical infrastructure would reduce connection costs for feeding power into the grid.
