Urussanga, Santa Catarina, Brazil presents a moderately good location for year-round solar energy generation, though with notable seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The solar energy output at this Southern Sub Tropics location shows significant fluctuation throughout the year. Summer delivers the strongest performance at 6.09 kWh per day per kW of installed capacity, making it the optimal season for solar generation. Spring follows as the second-best period with 5.14 kWh per day per kW, while autumn drops to 4.46 kWh per day per kW. Winter presents the most challenging season for solar production, generating only 3.37 kWh per day per kW of installed capacity. This represents nearly a 45% reduction compared to peak summer output, which is typical for locations at this latitude due to shorter days and lower sun angles during the Southern Hemisphere winter months.

Optimal Installation Configuration

For maximum year-round energy production at Urussanga, Santa Catarina, solar panels should be installed at a fixed tilt angle of 26 degrees facing North. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying position throughout the year and weighting the angles based on solar irradiance data.

Environmental and Weather Considerations

Several local factors in the Urussanga region could potentially impact solar energy production:

• High humidity levels typical of coastal Southern Brazil can lead to increased dust and salt accumulation on solar panels
• Frequent rainfall during certain seasons may cause temporary reductions in solar output
• Coastal proximity increases the risk of salt corrosion on panel frames and mounting systems
• Regional vegetation growth can create shading issues if not properly managed

Preventative Measures for Optimal Performance

To maximize solar energy production despite these environmental challenges, several installation strategies should be implemented:

• Install panels with anti-reflective coatings and hydrophobic surfaces to minimize dust and water spot accumulation
• Use corrosion-resistant mounting systems specifically designed for coastal environments
• Establish regular cleaning schedules, particularly during high-humidity periods
• Ensure adequate spacing between panel rows to prevent shading and allow for proper air circulation
• Implement proper drainage systems to prevent water pooling around installation areas

Regular maintenance and monitoring will be essential to maintain optimal performance throughout the year, particularly during the lower-output winter months when every bit of available solar energy becomes more valuable.

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 Urussanga

Seasonal solar PV output for Latitude: -28.4753, Longitude: -49.308 (Urussanga, 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 26° North in Urussanga, Brazil

To maximize your solar PV system's energy output in Urussanga, Brazil (Lat/Long -28.4753, -49.308) throughout the year, you should tilt your panels at an angle of 26° 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 Urussanga, 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 Urussanga, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° 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 Urussanga, 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 Urussanga, 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 Urussanga, Brazil

Topography Around Urussanga

The landscape surrounding Urussanga in southern Brazil presents a diverse mix of coastal plains and rolling hills characteristic of the Santa Catarina state region. Located approximately 200 kilometers south of Florianópolis, this area sits within the Atlantic Forest biome where the terrain gradually transitions from the coastal lowlands toward the more elevated interior regions. The immediate vicinity of Urussanga features relatively gentle topography with elevations ranging from near sea level along the coastal areas to modest hills reaching several hundred meters inland. The region is crossed by numerous small rivers and streams that have carved shallow valleys through the landscape, creating a gently undulating terrain pattern. These waterways flow generally eastward toward the Atlantic Ocean, following the natural slope of the land. Much of the surrounding countryside consists of agricultural land interspersed with patches of native Atlantic Forest vegetation on steeper slopes and in riparian zones. The coastal plain extends inland for several kilometers before giving way to more pronounced rolling hills that characterize much of the Santa Catarina interior.

Optimal Areas for Large-Scale Solar Development

The most promising locations for substantial solar photovoltaic installations would be found on the broader, flatter areas of the coastal plain and the gentler slopes of the inland rolling terrain. These zones offer several advantages including reduced construction complexity, lower earthwork requirements, and more efficient panel layout configurations. Agricultural areas with minimal slope present excellent opportunities for solar development, particularly where the land use can be adapted or where dual-use agricultural solar systems might be implemented. The relatively open nature of much of the farming landscape in this region means fewer obstacles from existing vegetation or structures. The elevated plateaus and ridge tops in the inland areas also merit consideration for solar development. While these locations may require more complex access infrastructure, they often provide consistent exposure conditions and can accommodate large arrays without significant grading work. The natural drainage patterns on these elevated sites also help minimize water management challenges during construction and operation. Areas to avoid would include the steeper hillsides where significant forest cover remains, as these locations would require extensive clearing and present challenging installation conditions. Similarly, the immediate floodplains of the various streams and rivers should be avoided due to potential flooding risks and environmental sensitivities. The transitional zones between the coastal plain and the inland hills often provide an ideal compromise, offering relatively flat to gently sloping terrain with good accessibility while maintaining adequate elevation for drainage and reduced flood risk. These intermediate elevation areas frequently have established road networks that would facilitate construction access and ongoing maintenance operations.
