Bauru, São Paulo, Brazil, located at latitude -22.2635 and longitude -49.1364, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant changes in daylight hours.

The solar energy potential in Bauru is substantial, with average daily electricity outputs per kilowatt of installed solar capacity varying across seasons. Summer yields the highest production at 6.97 kWh/day, followed closely by spring at 6.28 kWh/day. Autumn sees a slight decrease to 5.57 kWh/day, while winter experiences the lowest output at 4.72 kWh/day.

These figures indicate that Bauru is an excellent location for year-round solar energy generation, with peak production occurring during the summer months of December to February. The spring and autumn seasons also offer robust energy yields, making solar PV systems highly effective for most of the year.

Optimal Panel Installation

For fixed solar panel installations in Bauru, São Paulo, the ideal tilt angle to maximize year-round production is 20 degrees facing North. This orientation allows panels to capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's position in the Southern Hemisphere.

Environmental Considerations

While Bauru's climate is generally conducive to solar energy production, there are a few factors to consider:

1. Rainfall: The region experiences a wet season, typically from October to March, which may temporarily reduce solar output due to cloud cover.
2. Dust and pollen: During dry periods, accumulation of dust or pollen on panels can slightly decrease efficiency.

To mitigate these issues, regular cleaning and maintenance of solar panels is recommended, especially during and after the wet season. Additionally, installing panels at the optimal angle helps to maximize exposure and minimize the impact of temporary weather-related reductions in efficiency.

Overall, Bauru's tropical location and consistent sunlight make it an ideal site for solar PV installations, with only minor environmental factors to consider in system design and maintenance.

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 Bauru

Seasonal solar PV output for Latitude: -22.2635, Longitude: -49.1364 (Bauru, 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 20° North in Bauru, Brazil

To maximize your solar PV system's energy output in Bauru, Brazil (Lat/Long -22.2635, -49.1364) throughout the year, you should tilt your panels at an angle of 20° 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 Bauru, 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 Bauru, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° 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	15° 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 Bauru, 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 Bauru, 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 Bauru, Brazil

The topography around Bauru, Brazil, is characterized by gently rolling hills and plateaus, typical of the interior of São Paulo state. The city itself sits at an elevation of approximately 530 meters (1,740 feet) above sea level. The surrounding landscape is a mix of open grasslands, scattered patches of Atlantic Forest remnants, and agricultural areas. To the north and east of Bauru, the terrain gradually rises, forming part of the Western Plateau of São Paulo. This area features a series of low hills and shallow valleys, with elevations ranging from 500 to 700 meters. The soil in this region is predominantly red latosol, which is fertile and well-suited for agriculture. South and west of the city, the land becomes slightly flatter, with more extensive plains interspersed with occasional hills. This area is part of the Paraná River basin, and several smaller rivers and streams flow through the region, contributing to its undulating nature.

Potential for Large-Scale Solar PV

The areas most suited for large-scale solar photovoltaic (PV) installations near Bauru would be the flatter regions to the south and west of the city. These areas offer several advantages for solar energy development: Firstly, the relatively flat terrain reduces the need for extensive land preparation and allows for easier installation of solar panels. This can significantly lower construction costs and simplify maintenance procedures. Secondly, these areas often have fewer trees and obstacles that could cast shadows on the panels, maximizing sunlight exposure throughout the day. The open nature of the landscape also provides ample space for large arrays of solar panels. Additionally, the region's climate is favorable for solar energy production. Bauru experiences a tropical savanna climate with abundant sunshine throughout the year, particularly during the dry season from April to September. However, it's important to note that any large-scale solar PV project would need to consider factors such as proximity to existing power infrastructure, land ownership, and potential environmental impacts. Areas that are currently used for agriculture might also be suitable, provided there's a balance between energy production and food security concerns. While the immediate surroundings of Bauru offer good potential for solar PV, developers might also consider locations slightly further afield, particularly in the western part of São Paulo state, where even larger expanses of flat terrain can be found. These areas could potentially accommodate utility-scale solar farms capable of generating significant amounts of clean energy for the region.
