Solar Energy Potential in Barra Bonita, Brazil

Barra Bonita, Brazil, located at latitude -22.4717 and longitude -48.5491, offers a generally favorable location for solar energy generation throughout the year. Situated in the tropics, this location benefits from relatively consistent sunlight patterns compared to regions at higher latitudes. The solar energy production potential varies across the seasons, with the highest output occurring during the summer months. During summer, each kilowatt of installed solar capacity can generate approximately 6.90 kWh per day. Spring follows as the second most productive season with 6.30 kWh daily production per kilowatt installed. Energy production decreases somewhat during autumn, with daily generation averaging 5.56 kWh per kilowatt of installed capacity. Winter represents the least productive period, though still reasonably efficient with 4.78 kWh per day for each kilowatt installed. For those considering solar installation in Barra Bonita, it's worth noting that fixed solar panels should ideally be tilted at 21 degrees facing North to maximize year-round energy production. This specific angle optimizes the capture of solar radiation throughout the year, accounting for the location's position in the Southern Hemisphere.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Barra Bonita. The region experiences a distinct wet season, typically from October to March, which coincides with summer and early autumn. During this period, increased cloud cover and rainfall may occasionally reduce solar efficiency despite the generally higher solar potential of summer. Air pollution and dust accumulation represent another consideration. Barra Bonita is located in São Paulo state, which has significant agricultural activity including sugar cane cultivation. During harvest seasons, burning practices can create particulate matter in the air that may settle on panels and reduce efficiency.

Preventative Measures

To maximize solar energy production in Barra Bonita, several preventative measures are recommended:

• Install an automated cleaning system or implement a regular manual cleaning schedule, particularly during the dry season when dust accumulation is more significant
• Consider slightly adjustable mounting systems that allow for seasonal tilt optimization to capture more energy during winter months
• Use high-quality inverters with good performance in variable light conditions to better handle the fluctuations during the wet season
• Implement proper drainage systems around ground-mounted installations to prevent water accumulation during heavy tropical rains
• Select solar panels with good high-temperature performance, as the tropical climate can lead to elevated panel temperatures that may affect efficiency

With these considerations addressed, Barra Bonita remains an attractive location for solar energy production, with its year-round generation capability and relatively minor seasonal variations compared to locations at higher latitudes.

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

Ideally tilt fixed solar panels 21° North in Barra Bonita, Brazil

To maximize your solar PV system's energy output in Barra Bonita, Brazil (Lat/Long -22.4717, -48.5491) throughout the year, you should tilt your panels at an angle of 21° 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 Barra Bonita, 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 Barra Bonita, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
6° North in Summer	28° North in Autumn	38° North in Winter	16° 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 Barra Bonita, 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 Barra Bonita, 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 Barra Bonita, Brazil

The landscape around Barra Bonita, Brazil presents a diverse topography characterized by gently rolling hills, river valleys, and plateaus typical of the interior São Paulo state. Located in southeastern Brazil, Barra Bonita sits at an elevation of approximately 470 meters above sea level along the Tietê River.

Topographical Features

The region exhibits moderate relief with undulating terrain that gradually transitions between hills and lowlands. The Tietê River forms a significant topographical feature, winding through the landscape and creating a natural boundary that has shaped local geography for centuries. The river has been dammed to form the Barra Bonita Reservoir, which adds a substantial water feature to the topography. Surrounding the town, the terrain displays a patchwork of agricultural lands interspersed with areas of remaining native vegetation. The slopes are generally gentle to moderate, rarely exceeding 15-20% gradients in most areas. This rolling landscape continues for several kilometers in all directions, with occasional steeper hillsides.

Soil and Surface Conditions

The soils in the region are predominantly red latosols (oxisols), which are well-weathered, acidic soils common in tropical regions. These soils have developed from the underlying basaltic and sedimentary rocks that form the geological foundation of the area. Surface conditions vary from exposed soil in agricultural areas to vegetated patches where native cerrado (savanna) vegetation remains.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, the most suitable areas near Barra Bonita would be: The elevated plateaus to the north and northeast of the town offer ideal conditions for solar PV development. These areas feature relatively flat terrain with slopes generally less than 5%, minimizing the need for extensive grading and reducing construction costs. The elevation provides good exposure to sunlight throughout the day with minimal shadowing effects from surrounding topography. The gently sloping hillsides facing north (toward the equator) represent another prime location for solar installations. These north-facing slopes naturally receive more direct sunlight in the Southern Hemisphere, potentially increasing energy generation efficiency. Areas approximately 5-15 kilometers from the town center, particularly along the SP-255 highway corridor, combine favorable topography with existing infrastructure access. Agricultural lands that have already been cleared, particularly those with minimal agricultural productivity, present opportunities for solar development with reduced environmental impact. These areas typically have good drainage and minimal vegetation that would need clearing. Areas to avoid include the steeper slopes found in isolated pockets throughout the region, low-lying areas near the Tietê River that may be subject to flooding or higher humidity, and any remaining patches of native forest vegetation that hold conservation value. The combination of moderate elevation, generally open terrain, and existing road infrastructure makes the broader Barra Bonita region well-suited for solar energy development, particularly in the plateau areas that offer the optimal balance of topographical advantages.
