Solar Energy Production in Buri, São Paulo, Brazil

Buri, São Paulo, Brazil, located in the Southern Sub Tropics at coordinates -23.796, -48.5924, offers generally favorable conditions for solar PV energy generation throughout the year. This location benefits from consistent solar radiation that varies seasonally but remains productive in all four seasons. The seasonal energy production from solar PV in Buri shows a predictable pattern. Summer is the most productive period, with panels generating approximately 6.70 kWh per day for each kilowatt installed. Spring follows as the second most productive season with 5.86 kWh/day, while autumn yields 5.18 kWh/day. Winter, though less productive, still provides a reasonable 4.38 kWh/day per kilowatt installed.

Optimal Panel Installation

For fixed solar panel installations in Buri, São Paulo, the ideal tilt angle to maximize year-round energy production is 22 degrees facing North. This specific angle has been calculated taking into account the location's latitude, the sun's position throughout the year, and the weighted potential for solar energy production in different seasons.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Buri:

• Seasonal rainfall: The region experiences a rainy season that can temporarily reduce solar output due to cloud cover. Installing panels with high-efficiency ratings that perform better in diffuse light conditions can help mitigate this issue.
• Dust and agricultural particulates: As Buri is located in an agricultural region, dust and particulate matter can accumulate on panels. Regular cleaning schedules and potentially automated cleaning systems would help maintain optimal efficiency.
• Occasional hail: While not frequent, hailstorms can occur and potentially damage panels. Using tempered glass panels rated for impact resistance is recommended.

The relatively mild temperature range in Buri is actually beneficial for solar production, as extreme heat can reduce panel efficiency. However, ensuring adequate airflow beneath the panels during installation will help prevent any performance losses during hotter summer days. Despite these considerations, Buri's location offers excellent solar potential with relatively minor and manageable environmental challenges. The consistent year-round production, particularly strong in summer and spring, makes this location very suitable for solar PV installations with proper preparation and maintenance.

Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Ideally tilt fixed solar panels 22° North in Buri, Brazil

To maximize your solar PV system's energy output in Buri, Brazil (Lat/Long -23.796, -48.5924) throughout the year, you should tilt your panels at an angle of 22° 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 Buri, 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 Buri, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
8° North in Summer	29° North in Autumn	39° North in Winter	17° 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 Buri, 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 Buri, 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 Buri, Brazil

Topography of Buri, Brazil

The city of Buri is situated in the state of São Paulo in southeastern Brazil, nestled within a region of varied topography that transitions between the Atlantic Plateau and the Paranapanema River basin. The landscape around Buri features a mix of gently rolling hills, shallow valleys, and modest plateaus, with elevations generally ranging between 550 to 650 meters above sea level. The terrain is characterized by its undulating nature, with gradual slopes rather than steep inclines dominating the landscape. This rolling topography has been shaped over millennia by the weathering of the underlying sedimentary and basaltic rocks common to this part of Brazil, as well as by the action of numerous small rivers and streams that flow through the area, eventually feeding into the Paranapanema River system to the west. Vegetation in the region has been significantly modified by human activity, with much of the original Atlantic Forest having been cleared for agriculture and pasture. Today, the landscape is a mosaic of agricultural fields, scattered forest fragments, and grasslands, with more continuous forest cover remaining primarily on steeper slopes and along watercourses.

Solar PV Potential in the Buri Region

The topographical characteristics of the Buri region offer several advantages for large-scale solar photovoltaic (PV) development. The most suitable areas for solar PV installation include: The gently sloping plateaus to the east and northeast of Buri present ideal conditions for solar farms. These areas combine favorable topography with minimal shading issues, as the gradual slopes generally face north (in the Southern Hemisphere, north-facing slopes receive more direct sunlight). The relatively open nature of these plateaus, already cleared for agricultural use, minimizes the need for extensive land preparation. The broader valleys to the west and southwest of Buri also offer promising locations for solar development. These areas feature expansive, relatively flat terrain that would require minimal grading for installation of solar arrays. The open character of these valleys ensures minimal obstruction of sunlight throughout the day. Several elevated areas with minimal tree cover approximately 10-15 kilometers from the city center provide excellent solar exposure conditions. These higher-elevation sites often experience less morning fog than the lower valleys, potentially increasing overall solar efficiency. Areas to avoid for solar PV development include the steeper slopes found primarily in the southern portions of the region, which would require expensive terracing and present challenges for construction and maintenance. Similarly, the riparian zones along the numerous streams and rivers should be preserved for ecological reasons and are generally less suitable due to potential flooding and increased humidity. The soil composition around Buri, predominantly consisting of clay-rich soils derived from weathered basalt, provides generally good stability for ground-mounted solar installations, though seasonal rainfall patterns should be considered in foundation design. The existing road network connecting Buri to larger cities like Sorocaba and the broader São Paulo metropolitan area represents an additional advantage, facilitating the transportation of equipment and connection to the electrical grid, factors that complement the favorable topographical conditions for solar energy development.
