Solar Energy Production in Floresta, Brazil

Floresta, Brazil, located at latitude -23.6301 and longitude -52.0763 in the Southern Sub Tropics, offers very favorable conditions for solar photovoltaic (PV) energy generation throughout the year. The location experiences strong solar production potential across all seasons, making it an excellent candidate for solar energy investments. The seasonal energy production shows a clear pattern with the highest output during summer months when panels can generate approximately 6.95 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.14 kWh/day per kW installed. Energy generation decreases somewhat in autumn to 5.55 kWh/day, while winter represents the lowest production period at 4.33 kWh/day per kW installed.

Optimizing Panel Installation

For maximum year-round energy production at this location, fixed solar panels should be installed at a tilt angle of 21 degrees facing North. This specific angle has been calculated to optimize solar energy capture throughout the year based on Floresta's geographical position in the Southern Hemisphere. The substantial difference between summer and winter production rates (approximately 60% more energy in summer compared to winter) suggests that while the location is suitable year-round, energy planning should account for this seasonal variation. Despite winter showing the lowest production, the 4.33 kWh/day per kW figure remains quite respectable compared to many other global locations.

Environmental Considerations

The primary environmental factor that could potentially impact solar production in Floresta is the region's precipitation pattern. Located in a subtropical climate zone, Floresta can experience heavy seasonal rains that may temporarily reduce solar irradiance. To mitigate this impact, installations should incorporate:

• Adequate panel tilt to promote self-cleaning during rainfall
• Regular maintenance schedules aligned with dry season periods
• High-quality inverters capable of optimizing production during variable cloud conditions

Another consideration is dust accumulation, particularly during dry periods. Installing automated cleaning systems or planning periodic manual cleaning can help maintain optimal panel efficiency. Additionally, selecting panels with anti-soiling glass coatings can reduce maintenance requirements while maintaining higher production levels. Overall, Floresta presents an excellent location for solar PV installations with strong year-round production potential, especially during summer and spring months, with manageable environmental challenges that can be addressed through proper system design and maintenance protocols.

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 Floresta, Paraná

Seasonal solar PV output for Latitude: -23.6301, Longitude: -52.0763 (Floresta, Paraná, 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 21° North in Floresta, Paraná, Brazil

To maximize your solar PV system's energy output in Floresta, Paraná, Brazil (Lat/Long -23.6301, -52.0763) 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 Floresta, Paraná, 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 Floresta, Paraná, 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	16° 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 Floresta, Paraná, 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 Floresta, Paraná, 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 Floresta, Paraná, Brazil

The topography around Floresta, Brazil, situated at latitude -23.6301 and longitude -52.0763 in the state of Paraná, is characterized by gently rolling hills and plateaus typical of the southern Brazilian highlands. This region forms part of the Third Paraná Plateau, with elevations generally ranging between 400-600 meters above sea level. The landscape features a combination of open fields, agricultural land, and patches of remaining Atlantic Forest vegetation. The terrain generally slopes downward from east to west, with numerous small valleys created by the network of streams and rivers that are part of the Ivaí River basin. These waterways have carved shallow depressions throughout the region, creating a moderately undulating landscape rather than steep mountainous terrain. This gentle topography results from millions of years of erosion of the underlying basaltic rocks that form the geological foundation of the area.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic development near Floresta, the most suitable areas would be the elevated plateaus and gently sloping hillsides with southern to northern exposures. These areas offer several advantages for solar installations: The higher elevation plateaus to the east and northeast of Floresta provide excellent sites for solar farms as they typically experience less fog and atmospheric interference than lower-lying areas. These plateaus feature relatively flat terrain that minimizes the earthwork required for installation while still offering good drainage characteristics. The gently sloping areas facing north (toward the equator in the Southern Hemisphere) would be particularly advantageous for fixed-tilt solar arrays, as they naturally optimize the angle of solar incidence throughout the year. These north-facing slopes can be found scattered throughout the region, particularly along the southern edges of the plateau formations. Areas that have already been cleared for agriculture, which are abundant in the region surrounding Floresta, present opportunities for solar development with minimal additional environmental impact. These agricultural zones typically have existing access roads and are located away from densely forested areas, reducing both construction costs and ecological concerns. The western portions of the region, which tend to have slightly lower elevations and more open terrain, would also be suitable, particularly for larger installations requiring significant contiguous land area. These areas generally experience less cloud cover than the eastern sections, which are closer to the Serra do Mar mountain range and its associated weather patterns. It's worth noting that the soil composition in the region consists primarily of fertile terra roxa (red soil) derived from basalt decomposition, which provides good stability for mounting systems while allowing for effective cable trenching and foundation work required for solar installations.
