Andradina, São Paulo, Brazil offers a promising location for solar PV energy generation, situated in the tropics where sunlight remains relatively consistent throughout the year. This location experiences seasonal variations primarily characterized by wet and dry periods rather than dramatic temperature changes typical of temperate regions.
Seasonal Solar Production
The solar energy potential at Andradina demonstrates good year-round performance with some seasonal fluctuation. Summer months yield the highest energy output at 6.94kWh per day for each kilowatt of installed capacity. Spring follows closely with 6.48kWh/day, while autumn produces 5.81kWh/day. Winter shows the lowest output at 5.07kWh/day per installed kilowatt, though this reduction is less dramatic than in locations farther from the equator.
For maximum energy harvest throughout the year, fixed solar panels at this location should be tilted at 19 degrees facing North. This specific angle has been calculated to optimize annual solar production based on Andradina's geographical position at latitude -20.8655, longitude -51.3157.
Environmental Considerations
Several environmental factors could potentially impact solar production at this location:
- Seasonal rainfall during the wet season (typically summer) may reduce solar efficiency due to cloud cover, though these same months benefit from longer days
- Dust accumulation is a significant concern in this region, as dry periods can lead to airborne particulates settling on panel surfaces
- High temperatures during summer months may slightly reduce panel efficiency, as most photovoltaic cells experience efficiency drops above certain temperature thresholds
Preventative Measures
To maximize solar production despite these challenges, several installation practices are recommended:
- Implement regular cleaning schedules, particularly during dry seasons when dust accumulation is highest
- Install panels with sufficient elevation from the ground to minimize dust collection and allow for natural air circulation
- Consider self-cleaning panel technologies or hydrophobic coatings that reduce dust adhesion
- Ensure proper spacing between panels for adequate airflow, reducing temperature-related efficiency losses
- Use high-temperature rated inverters and components designed for tropical climates
With these considerations addressed, Andradina presents an excellent location for solar energy production with its consistent tropical sunlight and relatively minor seasonal variations in energy output compared to locations at higher latitudes.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 19° North in Andradina, Brazil
To maximize your solar PV system's energy output in Andradina, Brazil (Lat/Long -20.8655, -51.3157) throughout the year, you should tilt your panels at an angle of 19° 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 Andradina, 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 Andradina, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 27° North in Autumn | 36° North in Winter | 14° 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 Andradina, 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 Andradina, Brazil.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Andradina, Brazil
The region surrounding Andradina, Brazil is characterized by a predominantly flat to gently rolling topography, typical of the western São Paulo state landscape. Situated in the Paraná River basin, Andradina sits at an elevation of approximately 400 meters above sea level. The terrain gradually slopes toward the Paraná River, which forms the border with Mato Grosso do Sul state to the west.
Landscape Features
The landscape around Andradina consists primarily of open plains with scattered patches of remaining Cerrado vegetation - Brazil's tropical savanna ecosystem. The natural vegetation has been significantly altered by agricultural development, with large portions converted to pastureland and crop cultivation. The soil composition tends toward sandy-clay loams, providing reasonable drainage across much of the region. Small streams and tributaries of the Paraná River system create shallow valleys throughout the area. The most significant water feature near Andradina is the Tietê River, which flows westward before joining the Paraná River. This river system has been modified by several hydroelectric dams, creating reservoirs that have altered some of the original topography.Solar PV Potential Areas
For large-scale solar photovoltaic installations, several areas around Andradina present favorable conditions. The northwestern sector of the municipality, extending toward Ilha Solteira, offers extensive flat terrain with minimal obstruction from natural features. These areas have been largely cleared for agricultural use, providing open expanses suitable for solar array deployment. The elevated plateaus between Andradina and Castilho, to the west, represent another promising zone. These areas experience minimal shadowing effects due to their elevation and lack of tall vegetation or significant geographical barriers. The stable soil conditions also reduce construction challenges for mounting systems. The southeastern corridor extending toward Guaraçaí contains gently sloping fields that receive consistent solar exposure throughout the day. The gradual incline in some sections can actually be advantageous for solar panel positioning, potentially increasing energy capture efficiency. Areas to potentially avoid include the immediate riparian zones along the river systems, which may be subject to seasonal flooding or have higher humidity levels. Additionally, any remaining densely forested patches would require clearing, creating both environmental concerns and additional development costs. The region's climate, with predominantly clear skies during much of the year, enhances the suitability of these topographical features for solar energy development. The combination of flat terrain, minimal natural obstacles, and established infrastructure from agricultural development makes much of the land surrounding Andradina conducive to large-scale solar projects.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Brazil?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil.
