Aramina, São Paulo, Brazil presents a highly favorable location for year-round solar photovoltaic energy generation. Located in the tropical region where sunlight remains consistent throughout most of the year, this area experiences the typical wet and dry seasonal patterns rather than traditional temperature-based seasons.
Solar Energy Production Potential
The solar energy output data for Aramina demonstrates excellent year-round performance. Summer provides the highest energy generation at 6.70kWh per day per kW of installed solar capacity, making it the peak production season. Spring follows closely with 6.22kWh/day per kW, while autumn delivers 5.80kWh/day per kW. Even during winter, the lowest production period, the location still generates a respectable 5.23kWh/day per kW. This consistent performance throughout all seasons makes Aramina an ideal location for solar installations, with summer and spring being the optimal times for maximum energy generation. The relatively small variation between seasons ensures reliable energy production year-round.Optimal Panel Configuration
For fixed panel installations at this location, the ideal angle to tilt panels is 19 degrees North to maximize total year-round production from solar PV. This calculation accounts for the daily solar elevation angles at this latitude, optimal panel positioning, and weights these factors using solar irradiance data while considering Earth's elliptical orbit.Environmental and Weather Considerations
Several environmental factors could potentially impact solar production efficiency in Aramina:- Tropical rainfall and humidity: The wet season brings heavy precipitation and high humidity levels that can reduce panel efficiency and create maintenance challenges
- Dust and particulate accumulation: Dry seasons may lead to dust buildup on panels, reducing light transmission and energy output
- High temperatures: Intense tropical heat can decrease panel efficiency as photovoltaic cells perform less efficiently at elevated temperatures
Preventative Measures for Optimal Performance
To maximize energy production and system longevity, several installation strategies should be considered:- Enhanced drainage systems: Install proper water drainage around panel arrays to prevent water pooling and ensure quick runoff during heavy rains
- Regular cleaning protocols: Implement scheduled panel cleaning, particularly during dry seasons, to remove dust and debris accumulation
- Improved ventilation: Design installations with adequate airflow beneath panels to reduce operating temperatures and maintain efficiency
- Quality mounting systems: Use corrosion-resistant materials suitable for high humidity environments to ensure long-term structural integrity
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 Aramina
Seasonal solar PV output for Latitude: -20.1669, Longitude: -47.8273 (Aramina, 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 19° North in Aramina, Brazil
To maximize your solar PV system's energy output in Aramina, Brazil (Lat/Long -20.1669, -47.8273) 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 Aramina, 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 Aramina, 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 Aramina, 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 Aramina, 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 Aramina, Brazil
Topographical Features of the Aramina Region
The area surrounding Aramina in São Paulo state sits within the Brazilian Highlands, characterized by gently rolling hills and elevated plateaus that form part of the Serra Geral geological formation. This region experiences a gradual transition from the higher elevations of the Mantiqueira mountain range to the east toward the more moderate terrain of the western São Paulo interior. The landscape features undulating topography with elevations typically ranging between 500 and 800 meters above sea level, creating a series of broad ridges and shallow valleys that extend across the countryside.
The terrain around Aramina consists primarily of weathered crystalline rocks covered by deep, reddish soils typical of the Brazilian shield. These geological formations have created relatively stable ground conditions with moderate slopes that rarely exceed 15 degrees. The area benefits from good natural drainage due to its elevated position and the presence of numerous small streams and tributaries that flow toward larger river systems in the region.
Agricultural Land Use and Existing Infrastructure
Much of the surrounding landscape has been modified for agricultural purposes, particularly cattle ranching and crop cultivation including sugarcane, coffee, and citrus fruits. This existing land use pattern has resulted in large cleared areas with minimal tree coverage, creating expansive open spaces that could potentially accommodate solar installations. The region benefits from established rural road networks that connect farming operations to regional markets, providing existing infrastructure that could support solar development projects.
The agricultural nature of the area means that land parcels tend to be relatively large and consolidated, which presents advantages for utility-scale solar development. Many properties in the region encompass hundreds of hectares of contiguous land, offering the scale necessary for major photovoltaic installations without the complications of assembling multiple smaller parcels.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be the elevated plateau areas to the north and west of Aramina, where the terrain is relatively flat and experiences minimal shading from topographical features. These areas offer consistent south-facing slopes that would maximize solar exposure throughout the day while maintaining gentle gradients that simplify construction and maintenance activities.
The broad ridgetops and gently sloping hillsides provide ideal conditions for solar arrays, as they offer unobstructed sky views and natural drainage that prevents water accumulation around equipment. Areas with elevations between 600 and 700 meters would be particularly advantageous, as they benefit from clearer atmospheric conditions while remaining accessible for construction equipment and ongoing maintenance operations.
The existing cleared agricultural lands, particularly those currently used for pasture or annual crops, would present the most straightforward development opportunities. These areas already have established property boundaries, existing access roads, and proximity to electrical transmission infrastructure that serves the agricultural operations. The relatively stable clay-rich soils in these locations would provide solid foundations for solar mounting systems while the open terrain would minimize the need for extensive site preparation or vegetation clearing.
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.
