Solar Energy Production in Cardoso, São Paulo, Brazil
Cardoso, São Paulo, Brazil, located at -20.0915, -49.9513 in the tropical region, offers a promising location for solar PV (photovoltaic) energy generation throughout the year. In this region, where sunlight remains relatively consistent and seasons are primarily distinguished by wet and dry periods rather than temperature variations, solar energy can be a reliable power source. The solar energy production in Cardoso varies by season, with the highest output occurring during summer months. A solar installation can be expected to generate 7.01kWh per day for each kilowatt of installed capacity during summer. Spring follows as the second most productive season with 6.50kWh/day, while autumn yields 5.80kWh/day. Winter, though less productive, still offers a respectable 5.16kWh/day per kilowatt installed. For maximizing year-round solar production in Cardoso, São Paulo, fixed solar panels should be installed at a tilt angle of 19 degrees facing North. This specific angle has been calculated to optimize annual energy harvest based on the location's position relative to the sun's path throughout the year.Environmental and Weather Considerations
Several factors could potentially impact solar production in Cardoso. The region experiences a distinct wet season, typically bringing increased cloud cover and rainfall which can temporarily reduce solar output. Dust accumulation is another consideration in this tropical environment, as it can gradually diminish panel efficiency if not addressed. To mitigate these challenges, several preventative measures can be implemented:- Installing panels with self-cleaning capabilities or establishing a regular cleaning schedule, especially after the dry season when dust accumulation is highest
- Using weather-resistant mounting systems designed to withstand potential heavy rainfall during wet seasons
- Incorporating micro-inverters or power optimizers to minimize the impact of partial shading from passing clouds
- Considering slightly oversized systems to compensate for reduced productivity during cloudier periods
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 Cardoso, Brazil
To maximize your solar PV system's energy output in Cardoso, Brazil (Lat/Long -20.0915, -49.9513) 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 Cardoso, 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 Cardoso, 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 |
|---|---|---|---|
| 4° North in Summer | 26° 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 Cardoso, 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 Cardoso, 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 Cardoso, Brazil
Cardoso, Brazil, situated at the coordinates -20.0915, -49.9513, lies within the northwestern region of São Paulo state. The topography of this area is characterized primarily by gently rolling hills and expansive plateaus typical of Brazil's interior highlands. The terrain around Cardoso is part of the larger Paraná Plateau, a geological formation that dominates much of southeastern Brazil. The landscape features modest elevation changes, with altitudes generally ranging between 400 and 550 meters above sea level. This relatively flat to undulating terrain creates wide open spaces with few significant natural barriers. The soil composition tends toward latosols (oxisols), which are reddish in color due to their high iron oxide content, a characteristic feature of tropical regions with significant weathering.
Hydrological Features
The region is part of the Turvo-Grande River basin, with several smaller rivers and streams crossing the area. These waterways have, over geological time, carved shallow valleys into the plateau, creating the gentle undulations that characterize the local topography. The Grande River, which forms part of the border between São Paulo and Minas Gerais states, flows not far from Cardoso and influences the broader regional landscape.Vegetation and Land Use
Originally covered by a transition zone between Atlantic Forest and Cerrado (Brazilian savanna) vegetation, much of the natural landscape has been transformed by agricultural activities. Today, the area around Cardoso is dominated by agricultural land, particularly sugar cane plantations, soybean fields, and pastures for cattle ranching. Remnant patches of native vegetation persist mainly along waterways and in protected areas.Solar PV Suitability
For large-scale solar photovoltaic installations, the areas most suitable around Cardoso would be the elevated plateau sections with minimal slope. These locations offer several advantages for solar development: The gently sloping terrain to the north and northeast of Cardoso presents ideal conditions for solar farms, with gradients typically less than 5%. These areas provide natural drainage while minimizing the earthwork required for installation. Agricultural lands that have already been cleared of native vegetation, particularly those currently used for annual crops, would minimize environmental impact if converted to solar use. These areas are abundant in the region surrounding Cardoso. The higher plateau sections, especially those with southerly aspects (facing north in the Southern Hemisphere), receive consistent solar exposure throughout the year. These areas typically have well-drained soils that reduce the risk of flooding or erosion issues. Areas with proximity to existing transmission infrastructure would reduce connection costs. Given the agricultural development in the region, there is a reasonably developed electrical grid network that could potentially accommodate new generating capacity. The northwestern portions of the municipality, where the terrain flattens out toward the Grande River valley, offer particularly promising locations for large-scale installations due to their combination of favorable topography, existing access roads, and limited competing land uses. While the entire region benefits from favorable solar conditions, these specific areas combine the topographical, infrastructural, and environmental characteristics that would minimize development costs while maximizing potential energy production for utility-scale solar photovoltaic 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. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power. These include reduced import taxes on solar equipment, accelerated depreciation of investments in renewable energy projects, and preferential financing from public banks.
