Tomazina, Paraná, Brazil offers reasonably good conditions for year-round solar energy generation, though performance varies significantly between seasons. Located in the Southern Sub Tropics at coordinates -23.679, -49.984, this region experiences notable seasonal fluctuations in solar output.

Seasonal Solar Performance

Summer delivers the strongest solar performance at 6.89 kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows as the second-best period with 6.07 kWh daily output per kW. Autumn sees a moderate decline to 5.32 kWh per day per kW, while winter represents the weakest period at 4.45 kWh daily per kW. The data shows that summer and spring are clearly the ideal times for solar generation at this location, producing approximately 35-55% more energy than the winter months. However, even during winter, the location maintains reasonable solar output levels.

Optimal Panel Installation

For fixed panel installations at Tomazina, Paraná, the ideal tilt angle to maximize total year-round solar production is 21 degrees facing North. This angle has been calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance data to achieve optimal annual performance.

Environmental and Weather Challenges

Several local factors could potentially impact solar production in this subtropical Brazilian location:

• High humidity levels typical of subtropical climates can reduce solar panel efficiency
• Frequent rainfall and thunderstorms, particularly during summer months, may temporarily reduce output
• Dense cloud cover during wet seasons can significantly impact daily generation
• Dust and organic debris accumulation from the humid environment

Preventative Measures for Better Performance

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

• Install panels with adequate ventilation spacing to reduce heat buildup in humid conditions
• Implement regular cleaning schedules to remove dust, pollen, and organic matter
• Use high-quality inverters with good heat tolerance ratings
• Consider micro-inverters or power optimizers to minimize impact of partial shading from weather
• Ensure proper drainage around installations to prevent water pooling

Despite these potential challenges, Tomazina's location offers solid solar potential throughout the year, with particularly strong performance during the warmer months when energy demand for cooling is typically highest.

Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Ideally tilt fixed solar panels 21° North in Tomazina, Brazil

To maximize your solar PV system's energy output in Tomazina, Brazil (Lat/Long -23.679, -49.984) throughout the year, you should tilt your panels at an angle of 21° 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 Tomazina, 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 Tomazina, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
8° North in Summer	29° North in Autumn	39° North in Winter	17° 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 Tomazina, 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 Tomazina, 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 Tomazina, Brazil

Topographical Features Around Tomazina

The area surrounding Tomazina in Paraná state sits within the Brazilian Highlands, characterized by gently rolling hills and broad valleys typical of the interior plateau region. The terrain gradually descends from higher elevations in the east toward the Paranapanema River valley system to the north and west. This landscape features moderate relief with elevations generally ranging from 400 to 800 meters above sea level, creating a series of undulating ridges separated by wide, open valleys.

The region's topography has been shaped by ancient geological processes and erosion patterns, resulting in relatively stable slopes and well-drained upland areas. The rolling nature of the terrain means that steep gradients are uncommon, with most slopes being gentle to moderate. Stream valleys cut through the landscape in dendritic patterns, creating natural drainage corridors that flow toward larger river systems.

Soil and Surface Conditions

The underlying geology consists primarily of sedimentary rocks and weathered materials that have produced fertile soils suitable for agriculture. Much of the original Atlantic Forest vegetation has been cleared over decades for farming and cattle ranching, leaving extensive areas of open pasturelands and agricultural fields. The soil composition includes clay-rich materials that provide good stability for infrastructure development, though seasonal variations in moisture content can affect ground conditions.

Surface drainage is generally good throughout the region due to the rolling topography, which helps prevent waterlogging during the rainy season. The combination of cleared land and well-drained soils creates favorable conditions for large-scale development projects requiring substantial flat or gently sloping areas.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be found on the broader ridge tops and gentle south-facing slopes that characterize much of the region around Tomazina. These elevated areas typically offer the best combination of relatively flat terrain, good drainage, and minimal shading from surrounding topographical features. The wide valleys between ridges also present excellent opportunities, particularly where they open toward the north and have been cleared for agricultural use.

Areas to the west and northwest of Tomazina appear particularly promising, where the terrain becomes somewhat flatter as it approaches the Paranapanema River valley. These locations benefit from extensive cleared pasturelands with gentle gradients that would require minimal grading for solar panel installation. The stable soil conditions and existing agricultural infrastructure in these areas would facilitate construction access and grid connectivity.

The broad plateau areas southeast of the town also offer significant potential, where rolling farmland provides ample space for large arrays while maintaining good solar exposure throughout the day. These locations benefit from being situated on higher ground with excellent natural drainage, reducing concerns about flooding or ground instability that might affect solar installations in lower-lying areas.

Brazil solar PV Stats as a country
