The location delivers its strongest solar performance during summer months, generating 6.37kWh per day for each kW of installed solar capacity. Spring follows as the second-best season with 5.97kWh/day per kW, while autumn produces 5.77kWh/day per kW. Winter represents the lowest production period at 5.16kWh/day per kW, but this still provides substantial energy output. The difference between the best and worst seasons is only about 19%, indicating relatively stable year-round performance.Optimal Installation Setup
For maximum energy production at this location, solar panels should be installed at a fixed tilt angle of 20 degrees facing north. This angle has been calculated to optimize total annual output by accounting for the sun's path throughout the year and the Earth's orbital patterns.Environmental Factors and Challenges
Several local factors could potentially impact solar energy production at Desterro de Entre Rios:- Tropical rainfall: Heavy rains during wet seasons can reduce solar output and create debris buildup on panels
- High humidity: Can cause corrosion of electrical components and reduce system efficiency over time
- Dust and vegetation: Rapid plant growth and dust accumulation can shade panels and reduce output
- Temperature effects: High tropical temperatures can decrease panel efficiency
Preventative Measures
To maximize energy production despite these challenges, several installation strategies should be considered:- Regular cleaning systems: Install automated washing systems or schedule frequent manual cleaning to remove dust, debris, and organic matter
- Proper ventilation: Ensure adequate airflow around panels to reduce operating temperatures and improve efficiency
- Quality mounting systems: Use corrosion-resistant materials designed for high-humidity tropical environments
- Vegetation management: Maintain clear areas around installations and trim nearby trees regularly to prevent shading
- Enhanced drainage: Design installations with proper water drainage to prevent standing water and moisture damage
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 Desterro De Entre Rios
Seasonal solar PV output for Latitude: -20.6407, Longitude: -44.2802 (Desterro De Entre Rios, 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 Desterro De Entre Rios, Brazil
To maximize your solar PV system's energy output in Desterro De Entre Rios, Brazil (Lat/Long -20.6407, -44.2802) 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 Desterro De Entre Rios, 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 Desterro De Entre Rios, 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.

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 Desterro De Entre Rios, 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 Desterro De Entre Rios, Brazil
Topographical Features of Desterro de Entre Rios
Desterro de Entre Rios sits within the rolling hills and elevated plateaus characteristic of Minas Gerais state in southeastern Brazil. The municipality is positioned at approximately 900 meters above sea level, placing it within the Brazilian Highlands region. This elevated terrain creates a landscape of gentle to moderate slopes interspersed with flatter valley areas and ridge tops. The local topography is dominated by the ancient geological formations of the Brazilian Shield, resulting in weathered hills with rounded summits and broad valleys. The terrain exhibits the typical features of the Mantiqueira Mountains region, though at a more moderate elevation than the highest peaks of this range. Rocky outcrops of granite and gneiss occasionally punctuate the landscape, while much of the area features deep, weathered soils developed over millions of years. Water courses have carved numerous small valleys throughout the region, creating a dendritic drainage pattern that flows generally toward the larger river systems. These valleys tend to be relatively shallow compared to more mountainous regions, contributing to the overall gentle nature of the local relief.Terrain Suitability for Solar Development
The gently rolling topography around Desterro de Entre Rios presents several advantages for large-scale solar photovoltaic installations. The elevated plateau areas and broad ridge tops offer relatively flat to gently sloping terrain that requires minimal grading for solar panel placement. These higher elevation sites also benefit from reduced atmospheric interference and excellent exposure to solar radiation throughout the day. The most suitable areas for solar development would be the expansive hilltops and plateau surfaces that characterize much of the local landscape. These locations typically feature slopes of less than 10 degrees, making them ideal for standard solar mounting systems without requiring extensive earthwork. The well-drained nature of these elevated sites also reduces concerns about flooding or water accumulation that could affect solar installations. Areas along the broader valley floors also present opportunities for solar development, particularly where agricultural land use has created large, relatively flat parcels. These valley locations often provide easier access for construction and maintenance vehicles, though careful site selection would be necessary to avoid areas prone to seasonal water accumulation. The region's moderate relief means that most potential solar sites would not face significant shading issues from nearby terrain features. The gentle nature of the topography also facilitates the construction of access roads and transmission infrastructure necessary for large-scale solar projects, making development more economically viable than in areas with steeper or more rugged terrain.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.
