Atilio Vivacqua, Espírito Santo, Brazil presents a generally favorable location for year-round solar PV energy generation, with its tropical positioning providing consistent sunlight throughout most of the year where seasons are characterized more by wet and dry periods rather than traditional temperature variations.
Solar Energy Production Potential
The solar energy output data for this location shows solid performance across all seasons. Summer delivers the highest production at 6.12 kWh per day per kW of installed solar capacity, making it the optimal time for solar generation. Spring follows as the second-best season with 5.13 kWh/day, while autumn maintains good productivity at 5.50 kWh/day. Winter shows the lowest output at 4.56 kWh/day, though this still represents reasonable solar generation potential. For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 20 degrees facing north. This optimal angle is calculated by analyzing daily solar elevation angles at this latitude, determining optimal panel positioning, and weighting these angles according to solar irradiance data while accounting for Earth's elliptical orbit.Environmental and Weather Challenges
Several local factors could potentially impact solar production efficiency at this location. The tropical climate means extended wet seasons with heavy rainfall, high humidity, and frequent cloud cover during certain months. These conditions can reduce solar irradiance and create challenges for optimal energy generation. The high humidity typical of tropical regions can lead to accelerated corrosion of solar panel components and mounting systems. Additionally, the combination of heat and moisture creates ideal conditions for biological growth, including algae, moss, and other organic matter that can accumulate on panel surfaces and significantly reduce efficiency. Tropical storms and intense weather events are another concern, as they can potentially damage installations and interrupt power generation for extended periods.Preventative Measures for Optimal Performance
Several strategies can help maximize solar energy production despite these environmental challenges:- Install panels with anti-reflective coatings and self-cleaning surfaces to minimize the impact of dust and organic buildup
- Use corrosion-resistant mounting systems made from marine-grade aluminum or stainless steel components
- Implement regular cleaning schedules, particularly during and after wet seasons when biological growth is most likely
- Design installations with adequate drainage to prevent water accumulation around mounting points
- Choose panels rated for high humidity and temperature variations typical of tropical climates
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 Atilio Vivacqua
Seasonal solar PV output for Latitude: -20.9547, Longitude: -41.191 (Atilio Vivacqua, 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 Atilio Vivacqua, Brazil
To maximize your solar PV system's energy output in Atilio Vivacqua, Brazil (Lat/Long -20.9547, -41.191) 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 Atilio Vivacqua, 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 Atilio Vivacqua, 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 |
|---|---|---|---|
| 5° North in Summer | 26° North in Autumn | 36° 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 Atilio Vivacqua, 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 Atilio Vivacqua, 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 Atilio Vivacqua, Brazil
Topographical Features of Atilio Vivacqua Region
The landscape surrounding Atilio Vivacqua in Espírito Santo state presents a diverse topographical profile characteristic of Brazil's southeastern coastal region. This area sits within the Atlantic Forest biome, where rolling hills and moderate elevations dominate the terrain. The municipality occupies a position between the coastal lowlands to the east and the more elevated interior highlands to the west. The immediate vicinity features undulating terrain with elevations ranging from approximately 200 to 800 meters above sea level. These gentle to moderate slopes are interspersed with river valleys that have carved their way through the landscape over millennia. The region's topography reflects its geological history, with weathered crystalline rocks forming much of the underlying foundation, creating relatively stable ground conditions. Drainage patterns in the area flow generally eastward toward the Atlantic Ocean, with several small to medium-sized waterways creating natural valleys and floodplains. The terrain becomes progressively more mountainous as one moves inland toward the west, while flattening out toward the coastal areas to the east.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be found on the broader ridgetops and plateau areas that characterize the higher elevations surrounding Atilio Vivacqua. These elevated areas typically offer several advantages including reduced atmospheric interference, consistent exposure conditions, and often feature more open terrain with fewer obstructions from vegetation or existing development. The gently sloping hillsides facing northward would be particularly well-suited for solar installations, as they provide optimal orientation for capturing solar radiation throughout the day while maintaining manageable gradients for construction and maintenance access. Areas with slopes between 5 and 15 degrees are generally considered ideal, as they allow for natural drainage while maximizing solar exposure. Valley floors and floodplain areas, while potentially offering flat terrain that might seem attractive for development, would typically be less suitable due to potential flooding risks, higher humidity levels, and possible shading from surrounding elevated terrain during certain times of the day. Additionally, these lower-lying areas often contain more valuable agricultural land or sensitive ecological zones. The transitional zones between the steeper mountainous terrain to the west and the flatter coastal regions to the east present some of the most promising opportunities. These areas often feature large expanses of relatively gentle terrain with good drainage characteristics and fewer environmental constraints than either the mountainous regions or the more ecologically sensitive coastal areas.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.
