Camargo, Rio Grande do Sul, Brazil presents a moderately favorable location for year-round solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.
Seasonal Solar Performance
The solar energy output at this Southern Sub Tropics location shows substantial fluctuation throughout the year. Summer delivers the strongest performance at 7.42 kWh per day per kW of installed capacity, making it an excellent time for solar generation. Spring follows as the second-best season with 6.05 kWh per day per kW, still providing robust energy production. However, the location experiences notably reduced solar output during cooler months. Autumn drops to 4.91 kWh per day per kW, while winter reaches the yearly minimum of just 3.61 kWh per day per kW. This represents a significant 51% reduction in daily energy generation compared to peak summer performance.Optimal Installation Configuration
For maximum year-round energy production at Camargo, Rio Grande do Sul, solar panels should be installed at a fixed tilt angle of 25 degrees facing North. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying elevation throughout the year and weighting for daily solar potential based on irradiance data.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production at this location:- Seasonal cloud cover: The dramatic reduction in winter solar output suggests increased cloud coverage during cooler months, which is common in subtropical regions
- Humidity and moisture: Subtropical climates typically experience high humidity levels that can reduce panel efficiency and create more frequent cleaning requirements
- Storm activity: Southern Brazil can experience severe weather including hailstorms and strong winds during certain seasons
Preventative Measures for Enhanced Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Regular maintenance scheduling: Implement more frequent panel cleaning during high-humidity periods to prevent efficiency losses from dirt and moisture buildup
- Robust mounting systems: Use reinforced mounting hardware designed to withstand strong winds and potential hail damage
- Proper ventilation: Ensure adequate airflow around panels to minimize efficiency losses from heat buildup in humid conditions
- Quality panel selection: Choose panels with superior performance ratings in high-humidity environments and better temperature coefficients
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Solar output per kW of installed solar PV by season in Camargo
Seasonal solar PV output for Latitude: -28.6138, Longitude: -52.2195 (Camargo, 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 25° North in Camargo, Brazil
To maximize your solar PV system's energy output in Camargo, Brazil (Lat/Long -28.6138, -52.2195) throughout the year, you should tilt your panels at an angle of 25° 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 Camargo, 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 Camargo, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° North in Summer | 34° North in Autumn | 44° North in Winter | 21° 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 Camargo, 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 Camargo, 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 Camargo, Brazil
Topographical Features of the Camargo Region
Camargo is situated in the northern region of Rio Grande do Sul, Brazil's southernmost state, within the broader landscape of the Brazilian Highlands. The terrain around this municipality is characterized by gently rolling hills and undulating plains that form part of the Serra Geral formation. The elevation in this area typically ranges from 400 to 600 meters above sea level, creating a moderately elevated plateau environment.
The topography consists primarily of smooth, rounded hills interspersed with broad valleys and gentle slopes. This landscape was shaped by ancient volcanic activity and subsequent erosion processes, resulting in relatively stable geological formations. The terrain is predominantly covered by grasslands and agricultural fields, with scattered patches of mixed forest, particularly along watercourses and in protected areas.
The region experiences a subtropical highland climate, with the elevated position contributing to moderate temperatures throughout the year. The rolling nature of the landscape provides natural drainage patterns, with several small streams and tributaries flowing through the valleys toward larger river systems. These waterways have carved gentle depressions in the terrain, creating a varied but generally accessible topographical profile.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations around Camargo would be the elevated plateaus and gentle south-facing slopes that characterize much of the northern and western portions of the municipality. These areas offer several topographical advantages, including naturally level or slightly inclined surfaces that minimize the need for extensive ground preparation and grading work.
The broad, open grassland areas present ideal conditions for solar development, as they typically lack significant vegetation that would require clearing and have relatively uniform soil conditions. These locations also tend to be above the immediate flood plains of local watercourses, reducing the risk of water-related damage to solar installations while maintaining good natural drainage.
The elevated plateau regions northwest of the town center would be particularly well-suited for large-scale projects. These areas combine favorable topographical conditions with good accessibility via existing rural roads and proximity to electrical infrastructure. The gentle gradients in these locations allow for efficient panel orientation while minimizing soil erosion risks that could affect long-term installation stability.
Areas with southern exposure on the moderate slopes would be especially valuable, as the natural inclination of the land can complement optimal panel positioning. The relatively stable geological conditions of the region, built on ancient volcanic bedrock, provide solid foundations for mounting systems and reduce concerns about ground subsidence or shifting that might affect solar installations over their operational lifespan.
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. These include reduced import taxes on solar equipment, accelerated depreciation of investments in renewable energy projects, and preferential financing from public banks. Additionally, some states offer additional incentives such as subsidies or grants for businesses that install solar systems.
