Manga, Minas Gerais, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical positioning where consistent sunlight is available throughout most of the year with seasons characterized more by wet and dry periods than temperature variations.
Solar Energy Production Performance
The solar energy output at this location shows remarkably consistent performance across all seasons. Spring emerges as the most productive period, generating 6.59 kWh per day for each kilowatt of installed solar capacity. Autumn follows closely with 6.25 kWh/day, while summer produces 6.18 kWh/day. Even winter, typically the lowest production season, still delivers a strong 6.04 kWh/day per kilowatt installed. This minimal seasonal variation makes Manga an ideal location for solar installations, as energy production remains reliable throughout the year. The difference between the best and worst performing seasons is only about 9%, which is exceptionally small compared to locations at higher latitudes.Optimal Panel Installation
For maximum year-round energy production at this location, solar panels should be installed at a fixed tilt angle of 15 degrees facing north. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying elevation angles throughout the year and weighting them according to solar irradiance data.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production at Manga and require attention during installation:- Wet season precipitation: Heavy rainfall during wet seasons can reduce solar output due to cloud cover and may leave water spots or debris on panels
- Dust accumulation: During dry periods, dust and particulate matter can build up on panel surfaces, reducing efficiency
- High humidity: Tropical humidity levels may affect electrical components and connections over time
- Intense UV exposure: Consistent strong sunlight, while beneficial for energy production, can accelerate wear on panel materials and mounting systems
Preventative Measures for Optimal Performance
To maximize energy production despite these challenges, several installation strategies should be implemented:- Proper drainage design: Install panels with adequate spacing and angling to allow rainwater to wash away debris naturally
- Regular maintenance scheduling: Plan cleaning routines during dry periods to remove dust buildup, and inspect systems after heavy rain seasons
- Quality component selection: Use marine-grade or tropical-rated electrical components, inverters, and wiring designed to withstand high humidity
- Ventilation considerations: Ensure proper airflow around panels and electrical components to prevent moisture buildup and overheating
- UV-resistant materials: Select mounting systems and protective materials specifically rated for high UV exposure environments
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 Manga
Seasonal solar PV output for Latitude: -14.6587, Longitude: -44.1262 (Manga, 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 15° North in Manga, Brazil
To maximize your solar PV system's energy output in Manga, Brazil (Lat/Long -14.6587, -44.1262) throughout the year, you should tilt your panels at an angle of 15° 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 Manga, 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 Manga, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° South in Summer | 21° North in Autumn | 30° North in Winter | 9° 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 Manga, 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 Manga, 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 Manga, Brazil
Topographical Features of the Manga Region
Manga is situated in the northern portion of Minas Gerais state, within Brazil's expansive Cerrado savanna region. The landscape surrounding this municipality is characterized by gently rolling hills and broad plateaus that form part of the Brazilian Highlands. The terrain exhibits a relatively moderate elevation, sitting comfortably within the elevated plains that define much of central Brazil's interior.
The topography features undulating grasslands interspersed with patches of native Cerrado vegetation, including scattered trees and shrubland. These rolling hills create a series of gentle slopes and ridges that provide natural drainage patterns across the landscape. The region lacks dramatic elevation changes, with most variations in height being gradual rather than steep or mountainous.
Water features in the area include seasonal streams and small tributaries that flow toward larger river systems during the wet season. The landscape is punctuated by occasional rocky outcrops and areas of exposed bedrock, typical of the ancient geological formations found throughout the Brazilian Shield region.
Climate and Environmental Characteristics
The surrounding environment is dominated by the tropical savanna climate typical of the Cerrado biome. This creates distinct wet and dry seasons, with the dry period extending through much of the year. The natural vegetation consists of drought-resistant grasses and scattered woody plants adapted to these seasonal rainfall patterns.
The open nature of the Cerrado landscape means that large areas experience minimal shading from trees or other vegetation. The relatively flat to gently rolling terrain, combined with the sparse canopy cover, creates extensive areas with unobstructed sky exposure throughout most of the day.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the elevated plateaus and gentle slopes that characterize the region's higher elevations. These areas offer several advantages including consistent wind flow for natural cooling of solar panels and minimal risk of flooding during the wet season.
The broad, open grasslands with minimal tree cover present ideal conditions for large solar arrays. These areas require minimal clearing and grading work, reducing installation costs and environmental impact. The gentle slopes also provide natural drainage while maintaining optimal positioning for solar panel orientation.
Areas with southern-facing slopes would be particularly well-suited for solar installations, as they can be positioned to maximize exposure throughout the day. The stable geological conditions of the Brazilian Shield provide excellent foundation support for large-scale solar mounting systems.
Regions closer to existing infrastructure, including roads and transmission lines, would offer additional advantages for solar development. The relatively flat terrain makes construction access easier and reduces the complexity of connecting solar installations to the electrical grid.
Areas with good natural drainage should be prioritized to prevent water accumulation around solar equipment during the rainy season. The higher elevation plateaus and ridge areas typically offer superior drainage compared to lower-lying valleys or depression 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]
