Coronel Domingos Soares, ParanĂ¡, Brazil shows moderate solar energy potential for year-round electricity generation, though with significant seasonal variation typical of its Southern Sub Tropics location.
Seasonal Solar Performance
The location experiences its strongest solar production during summer months, generating 6.41 kWh per day for each kilowatt of installed solar panels. This represents the peak performance period when solar installations operate at their highest efficiency. Spring provides the second-best solar generation at 5.53 kWh per day per kW, making it another favorable season for solar energy production. Autumn sees a notable decline to 4.84 kWh per day per kW as daylight hours shorten and sun angles become less favorable. Winter presents the most challenging period for solar generation, dropping to 3.72 kWh per day per kW of installed capacity. This represents a significant 42% reduction compared to summer peak performance, requiring careful consideration for year-round energy planning.Optimal Installation Configuration
For fixed panel installations at this location, the ideal tilt angle is 23 degrees North to maximize total year-round solar production. This angle is calculated by analyzing daily solar elevation angles throughout the year, determining optimal panel positioning, and weighting these angles based on solar irradiance data to achieve the best annual average performance.Local Environmental Factors
Several environmental factors at Coronel Domingos Soares could potentially impact solar energy production:- Subtropical climate patterns may bring periods of increased cloud cover and humidity, particularly during certain seasons
- Potential for dust and debris accumulation on panels, especially during drier periods
- Seasonal weather variations including possible storms or heavy rainfall that could affect system performance
- Morning fog or mist common in subtropical regions that may delay peak solar generation
Preventative Installation Measures
To maximize solar energy production despite these environmental challenges, several installation strategies prove effective: Regular cleaning schedules become essential, with automated cleaning systems or accessible panel positioning allowing for frequent maintenance. Proper drainage design prevents water accumulation during heavy rainfall periods common in subtropical climates. Installing panels with adequate ventilation spacing helps manage humidity effects and maintains optimal operating temperatures. Quality mounting systems with corrosion-resistant materials withstand the humid subtropical environment better than standard installations. Incorporating micro-inverters or power optimizers can minimize the impact of partial shading from passing clouds or weather-related obstructions. Strategic positioning away from areas prone to debris accumulation, such as near large trees or dusty surfaces, also improves long-term performance. Overall, while Coronel Domingos Soares presents reasonable solar potential, the significant seasonal variation and environmental factors require thoughtful system design and maintenance planning to achieve optimal year-round energy production.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 Coronel Domingos Soares
Seasonal solar PV output for Latitude: -26.1829, Longitude: -51.9778 (Coronel Domingos Soares, 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 23° North in Coronel Domingos Soares, Brazil
To maximize your solar PV system's energy output in Coronel Domingos Soares, Brazil (Lat/Long -26.1829, -51.9778) throughout the year, you should tilt your panels at an angle of 23° 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 Coronel Domingos Soares, 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 Coronel Domingos Soares, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° North in Summer | 32° North in Autumn | 41° North in Winter | 19° 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.

Topography for solar PV around Coronel Domingos Soares, Brazil
Topographical Features of the Region
Coronel Domingos Soares sits within the Serra do Mar mountain range system in southern Brazil, positioned in the state of ParanĂ¡ near the border with Santa Catarina. The terrain around this location is characterized by rolling hills and moderate elevation changes typical of the Atlantic Plateau region. The area features a mix of forested hillsides and cleared agricultural land, with elevations generally ranging from 800 to 1,200 meters above sea level. The landscape displays the classic undulating patterns of the Brazilian Highlands, with gentle to moderate slopes interspersed with flatter valley floors. Dense Atlantic Forest remnants cover many of the steeper hillsides, while agricultural activities have claimed much of the more accessible terrain. Small streams and tributaries create narrow valleys that cut through the landscape, contributing to the varied topographical character of the region.Climate and Environmental Conditions
The region experiences a humid subtropical climate with well-defined seasons. Winters bring cooler temperatures and occasional frost, while summers are warm and humid with frequent afternoon thunderstorms. The area receives substantial rainfall throughout the year, with precipitation levels supporting the lush vegetation that characterizes much of the Atlantic Forest biome. Morning fog and mist are common occurrences, particularly during the cooler months, as moisture from the Atlantic Ocean interacts with the elevated terrain. Cloud cover patterns vary seasonally, with clearer skies more prevalent during the winter months when high-pressure systems dominate the weather patterns.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be found on the broader plateau areas and gentle south-facing slopes that have already been cleared for agricultural use. These areas offer several advantages including relatively stable ground conditions, existing access infrastructure, and minimal environmental impact since the natural forest cover has already been removed. The flatter valley floors present excellent opportunities for large solar arrays, particularly where agricultural land could be repurposed or where dual-use arrangements with farming operations might be established. These locations typically offer easier construction access and reduced grading requirements, which significantly lower installation costs for utility-scale projects. Areas to the west and southwest of Coronel Domingos Soares show particular promise, where the terrain becomes more gently rolling and agricultural activity is more intensive. These zones combine favorable topographical conditions with existing infrastructure networks, including roads and electrical transmission lines that could support large-scale solar development.Infrastructure and Access Considerations
The region benefits from reasonable road networks connecting to larger population centers, though some areas remain relatively remote. Existing agricultural infrastructure provides a foundation that could support solar development, including access roads and some electrical infrastructure. The proximity to established farming communities means that skilled labor and basic services are available locally. Areas closer to existing electrical transmission infrastructure would be particularly attractive for large-scale solar projects, as connection costs represent a significant portion of project economics. The terrain generally allows for conventional construction techniques, though careful site selection would be necessary to minimize grading requirements and environmental impact.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]
