Solar Energy Potential in Campos Borges, Rio Grande do Sul, Brazil

Campos Borges, Rio Grande do Sul, located in the southern subtropical region of Brazil, offers generally favorable conditions for solar photovoltaic (PV) energy generation, though with notable seasonal variations. This location experiences significant differences in energy production throughout the year, making it important to understand its solar profile. The seasonal solar production at this location shows a clear pattern: summer months are highly productive with 7.63kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.02kWh/day. Autumn sees a moderate decrease to 4.89kWh/day, while winter represents the lowest production period with 3.64kWh/day per kilowatt installed.

Optimal Panel Installation

For fixed solar panel installations in Campos Borges, Rio Grande do Sul, the ideal tilt angle to maximize year-round energy production is 25 degrees facing North. This specific angle has been calculated based on the location's latitude and seasonal solar patterns, accounting for Earth's elliptical orbit and the weighted solar potential throughout the year.

Seasonal Considerations

The substantial difference between summer and winter production (a drop of approximately 52%) indicates that this location experiences significant seasonal variability. This means that system sizing should account for these lower winter yields if year-round consistent energy supply is required. The most productive period for solar generation occurs during the summer months (December through February in the Southern Hemisphere), followed by spring (September through November). These two seasons combined represent the optimal time for solar energy production in Campos Borges.

Environmental Factors and Mitigation

Being in a subtropical region, Campos Borges may experience periods of heavy rainfall and potentially high humidity, which could temporarily reduce solar efficiency. Installing panels with good drainage systems and anti-soiling coatings can help mitigate these effects. The region may also experience occasional hail storms, which presents a physical risk to solar panels. Using hail-resistant panels with tempered glass and proper mounting systems can provide protection against weather-related damage. Dust and pollen accumulation could be another concern in this agricultural region. Regular cleaning schedules and possibly automated cleaning systems for larger installations would help maintain optimal production levels. Overall, Campos Borges offers good potential for solar energy generation with proper system design that accounts for seasonal variations and environmental factors specific to this subtropical location.

Solar output per kW of installed solar PV by season in Campos Borges

Seasonal solar PV output for Latitude: -28.8942, Longitude: -53.0298 (Campos Borges, 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 Campos Borges, Brazil

To maximize your solar PV system's energy output in Campos Borges, Brazil (Lat/Long -28.8942, -53.0298) 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 Campos Borges, 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 Campos Borges, 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
13° North in Summer	34° North in Autumn	44° North in Winter	22° 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 Campos Borges, 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 Campos Borges, Brazil.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Campos Borges, Brazil

Campos Borges is situated in the southern region of Brazil, within the state of Rio Grande do Sul. The topography of this area is characterized by gently rolling hills and plateaus that form part of the southern Brazilian highlands. The landscape around Campos Borges features moderate elevation changes, with altitudes generally ranging between 400 and 500 meters above sea level. The terrain consists predominantly of open grasslands interspersed with patches of forest and agricultural lands. The region is part of what is locally known as the "Planalto Médio" or Middle Plateau, which is a transitional zone between the more mountainous areas to the east and the flatter plains to the west. This undulating landscape has been shaped over millennia by natural erosion processes, creating a series of shallow valleys and rounded hilltops.

Hydrography

The area around Campos Borges is well-drained by several small rivers and streams that are part of the Jacuí River basin. These waterways have carved gentle depressions in the landscape, creating natural drainage systems throughout the region. The Jacuí River itself flows some distance to the south of Campos Borges, eventually emptying into the Guaíba Lake near Porto Alegre.

Vegetation and Land Use

The native vegetation of this region would have been a mixture of grasslands (campos) and Atlantic Forest remnants. However, much of the land has been converted to agricultural use, with soybean, corn, and wheat being common crops. Cattle ranching is also prevalent in the area, taking advantage of the natural grasslands.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, the most suitable areas near Campos Borges would be the gently sloping hills with southern to northern exposures. These locations offer several advantages: The elevated plateaus to the north and northeast of Campos Borges present particularly favorable conditions for solar PV development. These areas have minimal shading from natural features, relatively flat terrain that requires less grading for installation, and good drainage to prevent water accumulation around solar infrastructure. The agricultural lands that feature minimal tree cover would also be well-suited for solar development, as they already have reduced biodiversity impacts compared to forested areas. The conversion of some agricultural land to solar farms could be done with minimal environmental disruption. Areas to avoid would include the steeper slopes found in some parts of the region, particularly those facing south (in the Southern Hemisphere, north-facing slopes receive more direct sunlight), as well as low-lying areas near waterways that might be prone to seasonal flooding. The existing road network around Campos Borges provides reasonable access to many of these potential solar development sites, which is an important logistical consideration for large-scale installations. Additionally, the presence of transmission infrastructure in the region, serving the existing agricultural and urban centers, could potentially be leveraged for new solar energy projects.

Brazil solar PV Stats as a country
