Jardim Alegre, Paraná, Brazil presents a moderately good location for year-round solar PV energy generation, situated in the Southern Sub Tropics at coordinates -24.2123, -51.7213. The location demonstrates reasonable solar potential throughout all seasons, though with notable seasonal variations that are typical for subtropical regions.
Seasonal Solar Performance
The solar energy output varies significantly across the seasons at this location. Summer delivers the highest production at 6.90 kWh per day per kW of installed solar capacity, making it the peak generation period. Spring follows as the second-best season with 6.04 kWh per day per kW, while autumn drops to 5.31 kWh per day per kW. Winter presents the lowest output at 4.23 kWh per day per kW, representing a substantial decrease of nearly 40% compared to summer production. For optimal year-round energy generation from a fixed panel installation at Jardim Alegre, Paraná, solar panels should be tilted at 22 degrees facing North. This angle maximizes total annual solar output by accounting for the sun's varying position throughout the year and the location's specific latitude.Environmental and Weather Challenges
Several local factors could potentially impede solar production at this Southern Sub Tropical location. The region experiences a distinct wet season that typically brings increased cloud cover, heavy rainfall, and higher humidity levels, which can reduce solar irradiance reaching the panels. Additionally, the subtropical climate may contribute to more frequent fog formation, particularly during cooler months, further limiting solar exposure. The area's agricultural setting means increased dust and particulate matter in the air, especially during harvest seasons and dry periods. This can accumulate on solar panel surfaces, creating a film that reduces light transmission and overall efficiency.Preventative Measures for Enhanced Production
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Install panels with adequate spacing to ensure proper ventilation and reduce moisture buildup
- Implement regular cleaning schedules, particularly during and after dusty agricultural seasons
- Use anti-reflective coatings on panels to minimize efficiency losses from dust accumulation
- Consider micro-inverters or power optimizers to minimize the impact of partial shading from clouds or debris
- Ensure proper drainage around installation areas to prevent water pooling that could create humidity issues
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Ideally tilt fixed solar panels 22° North in Jardim Alegre, Brazil
To maximize your solar PV system's energy output in Jardim Alegre, Brazil (Lat/Long -24.2123, -51.7213) throughout the year, you should tilt your panels at an angle of 22° 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 Jardim Alegre, 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 Jardim Alegre, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° 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 | 30° North in Autumn | 40° 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.

Topography for solar PV around Jardim Alegre, Brazil
Topographical Features Around Jardim Alegre
The terrain surrounding Jardim Alegre in Paraná state presents a predominantly rolling landscape characteristic of Brazil's southern plateau region. This area sits within the broader Paraná Basin, where gentle hills and undulating plains create a varied but generally accessible topography. The elevation changes are moderate rather than dramatic, with the landscape featuring a series of low ridges and shallow valleys that flow naturally across the region. The local topography is shaped by ancient geological processes that have created relatively stable ground conditions. The terrain consists mainly of sedimentary rock formations covered by fertile soils, which explains why agriculture thrives throughout this region. Small streams and waterways meander through the valleys, creating natural drainage patterns that have influenced both settlement patterns and land use over time.Terrain Characteristics for Solar Development
The rolling nature of the landscape around Jardim Alegre offers several advantages for large-scale solar photovoltaic installations. The moderate slopes provide natural drainage while avoiding the steep gradients that would complicate construction and maintenance activities. Many areas feature gentle south-facing slopes that would be particularly well-suited for solar panel orientation in the southern hemisphere. The terrain's stability is another significant factor favoring solar development. The underlying geology provides solid foundations for mounting systems, while the absence of extreme topographical features reduces the complexity and cost of site preparation. The landscape lacks the rocky outcrops or unstable soil conditions that might pose challenges for large-scale construction projects.Most Suitable Areas for Large-Scale Solar PV
The most promising locations for extensive solar installations would be found on the broader plateau areas and gentle hillsides that extend in multiple directions from Jardim Alegre. These areas combine favorable topographical conditions with practical accessibility considerations. The relatively flat to gently sloping terrain minimizes earthwork requirements while providing adequate drainage to prevent water accumulation around solar equipment. Areas with southern exposure on moderate slopes would be particularly attractive, as they naturally optimize panel positioning for maximum solar collection throughout the day. The open agricultural lands that characterize much of this region also offer the large, unobstructed spaces necessary for utility-scale solar farms without the complications of dense vegetation or significant elevation changes. The proximity to existing agricultural infrastructure, including access roads and electrical connections, makes many of these topographically suitable areas even more practical for solar development. The combination of favorable terrain, good accessibility, and existing infrastructure creates multiple potential sites within the broader region that could accommodate substantial solar installations.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]
