Solar PV Analysis of Lagoa Dos Patos, Brazil
Lagoa dos Patos, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical position where consistent sunlight is available throughout most of the year. The seasonal variations are characterized more by wet and dry periods rather than the dramatic temperature changes seen in temperate regions.
Solar Energy Production Potential
The solar energy output at this location shows strong performance across all seasons. Summer delivers the highest production at 6.42 kWh per day per kW of installed solar capacity, closely followed by spring at 6.34 kWh per day. Even during the lowest production period in winter, the system still generates a respectable 5.62 kWh per day per kW, while autumn maintains solid output at 6.16 kWh per day.
For optimal year-round energy capture, solar panels should be installed at a fixed tilt angle of 16 degrees facing north. This angle maximizes total annual production by accounting for the sun's path throughout the year and the location's specific latitude.
Environmental and Weather Challenges
Several environmental factors could potentially impact solar energy production at Lagoa dos Patos. The tropical climate brings distinct wet and dry seasons, with the wet season potentially creating challenges through increased cloud cover, heavy rainfall, and higher humidity levels that can reduce solar panel efficiency.
Dust accumulation during dry periods can significantly reduce panel performance by blocking sunlight from reaching the photovoltaic cells. The region may also experience occasional severe weather events typical of tropical areas, including strong winds and intense storms that could damage installations.
High humidity levels throughout much of the year can lead to corrosion of electrical components and mounting systems, while the combination of heat and moisture creates ideal conditions for vegetation growth that might shade panels if not properly managed.
Preventative Measures for Optimal Performance
Several strategies can help maximize solar energy production despite these challenges:
- Install panels with adequate spacing and ventilation to prevent overheating and allow air circulation
- Use corrosion-resistant materials and weatherproof electrical connections designed for tropical climates
- Implement regular cleaning schedules, particularly during dry seasons when dust accumulation is highest
- Design mounting systems to withstand high winds and provide proper drainage during heavy rainfall
- Maintain clear zones around installations to prevent vegetation from creating shade
Regular maintenance becomes particularly important in this environment. Monthly cleaning and quarterly inspections can help identify potential issues before they significantly impact energy production. Installing monitoring systems allows for real-time performance tracking, making it easier to detect when cleaning or maintenance is needed.
Despite these considerations, the consistently high solar output throughout the year makes Lagoa dos Patos an attractive location for solar energy projects, with proper installation and maintenance practices ensuring reliable long-term performance.

Solar output per kW of installed solar PV by season in Lagoa Dos Patos
Seasonal solar PV output for Latitude: -17.0143, Longitude: -44.6663 (Lagoa Dos Patos, 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 16° North in Lagoa Dos Patos, Brazil
To maximize your solar PV system's energy output in Lagoa Dos Patos, Brazil (Lat/Long -17.0143, -44.6663) throughout the year, you should tilt your panels at an angle of 16° 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 Lagoa Dos Patos, 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 Lagoa Dos Patos, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° North in Summer | 23° North in Autumn | 33° North in Winter | 11° 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 Lagoa Dos Patos, 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 Lagoa Dos Patos, Brazil
Topographical Features Around Lagoa dos Patos
The region surrounding Lagoa dos Patos in Minas Gerais, Brazil, sits within the Brazilian Highlands, characterized by gently rolling hills and elevated plateaus typical of the central Brazilian landscape. This area forms part of the Cerrado biome, where the terrain consists of moderately undulating topography with elevations generally ranging between 800 and 1,200 meters above sea level. The landscape features broad, rounded hilltops separated by shallow valleys and gentle slopes that create a naturally varied but not dramatically steep terrain.
The local topography is dominated by weathered crystalline rocks and sedimentary formations that have been shaped over millions of years into relatively stable, mature landforms. These geological foundations create a landscape of modest relief, where the difference between hilltops and valley floors typically measures between 100 and 300 meters. The terrain is punctuated by numerous small streams and seasonal watercourses that flow through the valleys, contributing to the formation of the gentle, erosional features that characterize this part of Minas Gerais.
Vegetation in the area consists primarily of Cerrado savanna, featuring scattered trees and shrubs interspersed with grasslands. This natural vegetation pattern reflects the underlying topography, with denser tree cover typically found in valleys and along watercourses, while more open grasslands occupy the hilltops and slopes. The relatively sparse natural vegetation and open character of much of the landscape means that large areas are already naturally clear or have been converted to agricultural use.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations in this region would be the elevated plateaus and broad hilltops that characterize the higher elevations of the local landscape. These areas offer several advantages for solar development, including relatively flat to gently sloping terrain that requires minimal grading and site preparation. The elevated positions also provide excellent exposure to solar radiation throughout the day, with minimal shading from surrounding topographical features.
The southern and southeastern facing slopes of the rolling hills present particularly favorable conditions for solar panel orientation, allowing for optimal positioning to capture maximum solar energy. These slopes typically have gradients gentle enough to accommodate large solar arrays while providing natural drainage that helps prevent water accumulation around installations. The stable geological foundation of these elevated areas also provides excellent support for the infrastructure required for major solar facilities.
Areas of converted agricultural land on the plateaus and gentle slopes would be especially well-suited for solar development, as they are already cleared of natural vegetation and often have existing access roads. The open character of these landscapes means that large, continuous solar installations can be developed without significant obstacles from trees or steep terrain. Additionally, the elevated positions of these sites often provide good access to existing electrical transmission infrastructure that typically follows the higher ground in this region.
Valley floors and areas immediately adjacent to watercourses should generally be avoided for large-scale solar installations due to potential flooding risks and the presence of more sensitive riparian ecosystems. The steeper slopes, while less common in this gently rolling landscape, would also present challenges for solar development due to increased installation costs and potential erosion concerns.
