Charqueada, São Paulo, Brazil presents a good to very good location for year-round solar energy generation, with consistent performance across all seasons despite some seasonal variation in output.

Solar Production Performance

The solar energy output at this location shows strong performance throughout the year, with summer delivering the highest generation at 6.78 kWh per day per kW of installed capacity. Spring follows closely with 6.22 kWh/day, while autumn produces 5.55 kWh/day. Winter shows the lowest output at 4.80 kWh/day, but this still represents reasonable production levels. Summer and spring emerge as the optimal seasons for solar generation, with summer providing approximately 41% more energy than the winter months. However, even the winter production remains substantial, making this location viable for consistent year-round solar energy generation. For maximum annual energy production, solar panels should be installed at a fixed tilt angle of 21 degrees facing north. This angle has been calculated to optimize total yearly output by accounting for the sun's position throughout all seasons.

Environmental and Weather Factors

Several local factors could potentially impact solar production efficiency at Charqueada:

• Dust and agricultural particles - The region's agricultural activities may generate dust and organic particles that accumulate on solar panels
• Seasonal humidity and moisture - High humidity levels can reduce panel efficiency and promote dirt adhesion
• Tropical weather patterns - Occasional heavy rainfall and storms typical of tropical climates
• Temperature effects - High ambient temperatures can reduce photovoltaic efficiency

Preventative Measures for Optimal Performance

To maximize energy production despite these challenges, several installation strategies should be implemented: Regular maintenance scheduling is essential, with panels cleaned every 4-6 weeks during dry periods and monthly during humid seasons. Installing an automated cleaning system or scheduling professional cleaning services will help maintain peak efficiency. Proper ventilation design should be incorporated by mounting panels with adequate air circulation space underneath to reduce operating temperatures. This helps counteract the efficiency losses from high ambient temperatures. Quality mounting systems designed for tropical conditions will ensure panels remain secure during storms while maintaining the optimal 21-degree tilt angle. Using corrosion-resistant materials is particularly important in humid environments. Monitoring systems should be installed to track performance and quickly identify when cleaning or maintenance is needed, ensuring the system operates at maximum capacity throughout the year.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Charqueada

Seasonal solar PV output for Latitude: -22.5372, Longitude: -47.7377 (Charqueada, 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 Charqueada, Brazil

To maximize your solar PV system's energy output in Charqueada, Brazil (Lat/Long -22.5372, -47.7377) 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 Charqueada, 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 Charqueada, 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
7° North in Summer	28° North in Autumn	38° 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 Charqueada, 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 Charqueada, 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 Charqueada, Brazil

Topographical Features Around Charqueada

The region surrounding Charqueada in São Paulo state presents a gently undulating landscape characteristic of the Brazilian Planalto Central. This area sits within the broader Paraná sedimentary basin, featuring relatively modest elevation changes that create a rolling terrain punctuated by occasional steeper slopes and valley systems. The topography consists primarily of low hills and broad valleys, with elevations typically ranging between 500 and 700 meters above sea level. The terrain slopes gradually toward the southeast, following the natural drainage patterns that feed into the Tietê River system. These gentle gradients are interrupted by more pronounced ridgelines and escarpments that run roughly parallel to the regional geological strike. Local relief is generally subdued, with most slopes falling between 2 and 8 degrees. The landscape has been significantly modified by centuries of agricultural activity, particularly sugar cane cultivation, which has resulted in extensive cleared areas with minimal tree coverage. This agricultural transformation has created large expanses of relatively flat to gently sloping terrain that extends across much of the surrounding countryside.

Drainage and Landform Patterns

The area's drainage network consists of numerous small streams and tributaries that flow into larger waterways. These watercourses have carved shallow valleys through the sedimentary rocks, creating a dendritic drainage pattern that influences the local topography. The valley floors are typically broad and flat, while the interfluves between drainage lines form gentle ridges and plateaus. Seasonal variations in precipitation affect the local landscape, with wet periods causing temporary flooding in lower-lying areas and dry periods revealing extensive flat surfaces suitable for development. The underlying geology consists mainly of sedimentary formations that weather to create relatively stable soils and landforms.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be the broad, gently sloping plateaus and ridge tops that characterize the interfluve areas between major drainage lines. These elevated positions offer several topographical advantages, including consistent sun exposure throughout the day and minimal shading from adjacent landforms. The agricultural plains extending northward and westward from Charqueada present particularly favorable conditions. These areas feature extensive flat to gently undulating terrain with slopes generally less than 5 degrees, making them ideal for large-scale solar array installation. The cleared agricultural land requires minimal preparation, and the stable soils provide good foundation conditions for mounting systems. Areas along the broader valley floors also offer potential for solar development, particularly where they form wide, flat corridors between low hills. However, these locations may be subject to occasional flooding during extreme weather events, requiring careful site evaluation and possibly elevated mounting systems. The southeastern portions of the region, where the terrain begins to slope more noticeably toward the Tietê River valley, would be less suitable for large installations due to increased topographical complexity and potential drainage issues. Similarly, the steeper escarpments and ridge faces should be avoided in favor of the more gentle summit areas and broad valley floors that dominate the local landscape.
