Correia Pinto, Santa Catarina, Brazil shows moderate potential for year-round solar energy generation, though with significant seasonal variation typical of its Southern Sub Tropics location. The solar output data reveals distinct patterns that make certain times of year much more productive than others.

Seasonal Solar Performance

Summer delivers the strongest solar performance at 6.54 kWh per day per kW of installed capacity, making it the peak season for solar energy generation. Spring follows as the second-best period with 5.29 kWh per day per kW, offering solid energy production. Autumn drops to 4.64 kWh per day per kW, representing a moderate decline from the warmer months. Winter shows the lowest output at just 3.45 kWh per day per kW, nearly half of summer's production. The ideal times for solar generation at this location are clearly summer and spring, when the combination of longer days and higher sun angles maximizes energy output. Winter presents the greatest challenge for solar installations, requiring careful system sizing to meet energy needs during this lower-production period.

Optimal Panel Installation

For fixed panel installations at Correia Pinto, Santa Catarina, the ideal tilt angle is 24 degrees facing North to maximize total year-round solar production. This angle represents the optimal compromise across all seasons, calculated by weighing daily solar elevation angles against actual solar irradiance data throughout the year.

Local Factors Affecting Solar Production

Several environmental and weather factors in this Southern Sub Tropics region can impact solar panel performance:

• High humidity levels can reduce panel efficiency and promote corrosion of electrical components
• Heavy rainfall during certain seasons may cause temporary shading and require robust drainage systems
• Temperature fluctuations between seasons can affect panel output, as extreme heat reduces efficiency
• Potential for strong winds during weather systems may require enhanced mounting security

Preventative Measures for Better Performance

To maximize solar energy production despite these challenges, several installation strategies prove effective:

• Use marine-grade wiring and corrosion-resistant mounting hardware to combat humidity effects
• Install panels with adequate spacing for air circulation to manage temperature buildup
• Design robust mounting systems capable of withstanding regional wind loads
• Ensure proper drainage around ground-mounted systems to prevent water accumulation
• Consider regular cleaning schedules during dusty or pollen-heavy seasons

Regular maintenance becomes particularly important in this climate, with periodic inspections helping identify humidity-related issues before they significantly impact energy production. The seasonal variation in output also suggests that battery storage or grid-tied systems may be beneficial to balance the lower winter production against higher summer generation.

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 Correia Pinto

Seasonal solar PV output for Latitude: -27.5551, Longitude: -50.3802 (Correia Pinto, 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 24° North in Correia Pinto, Brazil

To maximize your solar PV system's energy output in Correia Pinto, Brazil (Lat/Long -27.5551, -50.3802) throughout the year, you should tilt your panels at an angle of 24° 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 Correia Pinto, 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 Correia Pinto, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
11° North in Summer	33° North in Autumn	43° North in Winter	20° 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 Correia Pinto, 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 Correia Pinto, 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 Correia Pinto, Brazil

Topography of the Correia Pinto Region

Correia Pinto sits in the mountainous highlands of Santa Catarina state in southern Brazil, positioned within the Serra Geral mountain range. The terrain around this municipality is characterized by rolling hills, steep valleys, and elevated plateaus that create a complex landscape of varying elevations. The region forms part of the Brazilian Highlands, with altitudes typically ranging from 800 to 1,200 meters above sea level.

The topography is dominated by ancient volcanic formations and sedimentary rock structures that have been carved by centuries of erosion. Deep river valleys cut through the landscape, creating dramatic elevation changes over relatively short distances. The Canoas River system has played a significant role in shaping the local geography, with its tributaries creating numerous gorges and ravines throughout the area.

Mixed forests of Araucaria pine and Atlantic Forest remnants cover much of the steeper terrain, while agricultural activities have claimed many of the gentler slopes and valley floors. The climate in this elevated region is subtropical highland, with cooler temperatures than the coastal areas due to the altitude effect.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations around Correia Pinto would be the elevated plateaus and gently rolling uplands that characterize the higher elevations of the region. These areas offer several advantages including relatively flat or mildly sloping terrain that requires minimal grading and earthwork for solar panel installation.

The cleared agricultural lands on the broader ridgetops and plateau areas present excellent opportunities for solar development. These locations typically have fewer trees and existing infrastructure access, while the elevated positions help minimize shading from surrounding vegetation or topographic features. The consistent elevation of these plateau areas also means more predictable wind patterns that can help with natural cooling of solar panels.

Areas to the north and northeast of the town center, where the terrain opens up into broader agricultural valleys and upland pastures, would be particularly well-suited for large installations. These locations combine the benefits of relatively level ground with good access to existing road networks and electrical infrastructure.

The steeper valley sides and heavily forested areas would be less suitable due to challenging terrain, potential shading issues, and environmental concerns. Additionally, areas prone to fog formation in the deeper valleys might experience reduced solar exposure during certain weather conditions, making the higher, more exposed locations preferable for solar energy generation.

Brazil solar PV Stats as a country
