Cascavel, Paraná, Brazil, situated in the Southern Sub Tropics, offers a relatively favorable location for solar PV energy generation throughout the year, though with notable seasonal variations.

Seasonal Solar Production

The energy output from solar panels in Cascavel follows predictable seasonal patterns. Summer months deliver the highest production at 7.02kWh per day for each kilowatt installed, making December through February the prime time for solar generation. Spring follows as the second most productive season with 6.11kWh/day, while autumn yields a moderate 5.30kWh/day. Winter shows the lowest output at 3.96kWh/day, which is still reasonably productive but represents a significant drop from summer levels.

For maximum year-round energy production, fixed solar panels at this location should be installed at a tilt angle of 22 degrees facing North. This optimal angle has been calculated to capture the greatest amount of solar radiation across all seasons, accounting for Cascavel's specific latitude and the Earth's orbital patterns.

Environmental Considerations

Several environmental factors could potentially impact solar production in Cascavel:

• Dust and agricultural pollution: As Cascavel is located in an agricultural region, airborne dust and particulates from farming activities can accumulate on panels, reducing efficiency. Regular cleaning schedules are recommended, particularly during drier periods.
• Seasonal rainfall: The region experiences heavier rainfall during summer months, which can temporarily reduce production but also naturally cleans panels. Installing panels with adequate drainage and water-resistant connections is important.
• Occasional hail storms: The area can experience hail, particularly during transitional seasons. High-quality tempered glass panels with appropriate impact resistance ratings are recommended.

To maximize production, consider implementing a dual-axis tracking system rather than fixed panels, which could increase energy capture by up to 30% compared to the fixed 22-degree tilt. However, this comes with higher installation and maintenance costs that need to be weighed against the potential gains.

Overall, Cascavel presents a good location for solar PV installation with its strong summer and spring production compensating for the reduced winter output. With proper installation techniques and maintenance, a solar PV system here can provide reliable renewable energy throughout the year.

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

Ideally tilt fixed solar panels 22° North in Cascavel, Brazil

To maximize your solar PV system's energy output in Cascavel, Brazil (Lat/Long -25.0525, -53.3881) 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 Cascavel, 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 Cascavel, 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
9° North in Summer	30° North in Autumn	40° North in Winter	18° 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 Cascavel, 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 Cascavel, 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 Cascavel, Brazil

The city of Cascavel, located in the state of Paraná in southern Brazil, sits upon the third plateau of Paraná at an elevation of approximately 780 meters above sea level. The regional topography is characterized by gently rolling hills and plateaus, creating a landscape of undulating terrain with moderate variations in elevation. This western region of Paraná features a combination of open plains and subtle valleys carved by local river systems, most notably the Paraná River basin. The surrounding countryside displays a predominantly agricultural landscape, with vast fields extending across the plateau. Originally covered by Atlantic Forest and Araucaria moist forests, much of the native vegetation has been transformed into agricultural land over the past century. The soils in this region are notably fertile, particularly the characteristic reddish terra roxa (purple earth) soils that have made this area an important agricultural center.

Hydrography and Terrain Features

The hydrography around Cascavel is defined by several river basins, including tributaries that eventually flow to the Paraná River. The Iguaçu River basin influences the southern portions of the region. These waterways have carved subtle valleys through the plateau landscape over geological time. The terrain generally slopes westward toward the Paraná River, which forms part of Brazil's border with Paraguay. This gradual descent creates a landscape with good drainage characteristics and relatively stable geological features. The bedrock consists primarily of basaltic formations from the Serra Geral Formation, contributing to the region's moderately flat to rolling topography.

Optimal Areas for Solar PV Development

The most suitable areas for large-scale solar photovoltaic development near Cascavel would be the extensive agricultural plateaus surrounding the city. These locations offer several advantageous characteristics for solar energy production: The gently rolling terrain to the north and west of Cascavel presents large, continuous tracts of land with minimal shading concerns. These areas benefit from good solar exposure throughout the day due to their relatively flat nature and lack of significant natural obstacles. Agricultural lands that experience lower productivity or are undergoing crop rotation could be particularly appropriate for solar development, creating opportunities for agrivoltaic systems where agricultural activities continue beneath or between solar arrays. The plateaus extending toward the municipalities of Toledo and Marechal Cândido Rondon (northwest of Cascavel) offer extensive open spaces with favorable topographic conditions. These areas combine good drainage, stable soil conditions, and minimal flood risk—all important factors for solar infrastructure development. Areas with proximity to existing transmission infrastructure would reduce connection costs. The region around Cascavel has relatively well-developed electrical infrastructure due to its agricultural importance and proximity to the Itaipu hydroelectric dam, potentially facilitating grid integration for new solar projects. The southeastern portions of the region, toward the municipalities of Laranjeiras do Sul and Quedas do Iguaçu, also present viable locations with suitable terrain, though these areas have more variation in elevation and potentially more forest coverage to consider in development plans. It's worth noting that while the topography is generally favorable throughout the region, site-specific assessments remain essential. Factors such as localized slope orientation, soil stability, and environmental considerations would need detailed evaluation before final site selection for large-scale solar development.
