Miracatu, São Paulo, Brazil, situated in the Southern Sub Tropics at coordinates -24.1732, -47.3632, offers generally favorable conditions for solar PV energy generation throughout the year, though with notable seasonal variations.
Solar energy production at this location follows a predictable seasonal pattern. During summer months, panels can generate an impressive 5.85kWh per day for each kilowatt of installed capacity. This drops to 4.50kWh/day during autumn, reaches its lowest point in winter at 3.40kWh/day, and then recovers to 4.43kWh/day in spring.
Seasonal Performance
Summer clearly stands out as the prime season for solar generation in Miracatu, São Paulo, producing nearly 72% more energy than during the winter months. Spring and autumn offer moderate production levels, making them reliable shoulder seasons for solar energy collection.
For fixed panel installations at this location, the ideal angle to maximize year-round energy production is 21 degrees facing North. This specific tilt optimizes the annual solar harvest by balancing seasonal variations in the sun's position throughout the year.
Environmental Considerations
Several environmental factors could potentially impact solar production in Miracatu. The region experiences a humid subtropical climate with occasional heavy rainfall, particularly during summer months. These weather patterns can temporarily reduce solar efficiency due to cloud cover and precipitation.
The Atlantic Forest biome surrounding Miracatu means vegetation growth can be rapid, potentially causing shading issues if not managed properly. Additionally, the coastal proximity may introduce salt spray concerns for installations closer to the shoreline.
Preventative Measures
To maximize solar production in Miracatu, São Paulo, several preventative measures are recommended:
- Regular panel cleaning to remove dust, pollen, and salt deposits that can accumulate on surfaces
- Strategic placement away from fast-growing vegetation or implementation of vegetation management plans
- Installation of weather-resistant components designed for humid environments
- Consideration of micro-inverter or power optimizer technology to minimize the impact of partial shading
- Proper drainage systems to prevent water accumulation after heavy rains
With these considerations addressed, Miracatu presents a viable location for solar PV installations, with its year-round production capabilities making it a worthwhile investment for renewable energy generation.

Ideally tilt fixed solar panels 21° North in Miracatu, Brazil
To maximize your solar PV system's energy output in Miracatu, Brazil (Lat/Long -24.1732, -47.3632) throughout the year, you should tilt your panels at an angle of 21° 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 Miracatu, 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 Miracatu, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° 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 | 40° 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 Miracatu, 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 Miracatu, 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 Miracatu, Brazil
The topography around Miracatu, Brazil presents a varied and complex landscape characteristic of the Atlantic Forest region of São Paulo state. Located in the Vale do Ribeira area, Miracatu sits within a transitional zone between the coastal plains and the Serra do Mar mountain range. This creates a distinctive topographical profile marked by significant elevation changes within relatively short distances. The terrain in and immediately surrounding Miracatu is characterized by undulating hills that gradually rise toward the northwest, where they meet the more pronounced slopes of the Serra do Mar. These mountains form part of the Great Escarpment that runs along much of Brazil's southeastern coast. Elevations in the municipality range from approximately 30 meters above sea level in the valley floors to over 900 meters in the mountainous areas.
River Valleys and Drainage
The São Lourenço River and its tributaries have carved significant valleys through the landscape, creating natural corridors between the hills. These river systems have formed alluvial plains in some areas, though these flat expanses are limited in size compared to the surrounding elevated terrain. The drainage pattern follows a generally southeastern direction, eventually reaching the Atlantic Ocean.Vegetation and Land Cover
The natural vegetation consists primarily of Atlantic Forest formations, with varying density depending on altitude and human intervention. While much of the original forest has been modified by agricultural activities, significant patches remain, especially on steeper slopes and protected areas. This vegetation cover influences not only the visual landscape but also affects factors like soil stability and local microclimate.Solar PV Potential Areas
For large-scale solar photovoltaic development, several factors must be considered within this topographical context. The most suitable areas would be: The gentler slopes and plateaus found in the northeastern portions of the municipality offer some of the better conditions for solar installations. These areas provide relatively flat terrain that reduces construction complexity while still being elevated enough to minimize shading from surrounding features. Some of the cleared agricultural lands in the river valleys, particularly along the middle sections of the São Lourenço drainage basin, present opportunities for solar development. These areas offer the advantage of already being modified landscapes with existing access infrastructure, though potential flooding risks must be evaluated. The transitional zones between the hills and valleys, especially on south-facing gentle slopes, could accommodate solar arrays. These locations often represent a compromise between accessibility and optimal solar exposure.Challenging Areas
The steeper sections of the Serra do Mar mountains, primarily in the northwestern parts of the region, present significant challenges for large-scale solar development. The combination of dense forest cover, steep gradients, and difficult access makes these areas generally unsuitable despite their elevation. Similarly, the lowest-lying areas along the river courses face potential flooding concerns and may have higher humidity levels that could affect equipment longevity.Infrastructure Considerations
The existing road network around Miracatu follows the natural topography, with the main highways (particularly BR-116) traversing the more accessible valleys. This infrastructure pattern would influence solar development feasibility, as sites with proximity to these transportation corridors would reduce construction and maintenance costs. In conclusion, while the topography around Miracatu presents certain challenges for large-scale solar PV development, the intermediate elevations and modified landscapes offer viable opportunities, particularly in the northeastern sections and along the middle elevation zones where moderate slopes and existing clearings coincide with reasonable accessibility.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.
