Cerquilho, São Paulo, Brazil, located at latitude -23.1911 and longitude -47.7734, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant changes in daylight hours.

Seasonal Solar Performance

The solar energy potential in Cerquilho varies across the meteorological seasons. Summer yields the highest output at 6.55 kWh per day for each kilowatt of installed solar capacity. Spring follows with 5.89 kWh/day, then autumn with 5.28 kWh/day. Winter, while still productive, sees the lowest output at 4.39 kWh/day. These figures indicate that Cerquilho maintains good solar generation potential year-round, with peak performance during the summer months (December to February in the Southern Hemisphere). The relatively small difference between the highest and lowest seasonal outputs suggests a stable and reliable solar resource throughout the year.

Optimal Panel Orientation

For fixed solar panel installations in Cerquilho, São Paulo, the ideal tilt angle to maximize year-round energy production is 21 degrees facing North. This orientation allows panels to capture the most sunlight across all seasons, accounting for the location's position in the Southern Hemisphere and the Earth's elliptical orbit.

Environmental Considerations

While Cerquilho's climate is generally conducive to solar energy production, there are a few factors to consider: 1. Rainfall: The region experiences a wet season, typically from October to March. Heavy rain can temporarily reduce solar output and may require more frequent panel cleaning. 2. Dust and pollen: During dry periods, dust accumulation on panels can slightly decrease efficiency. To mitigate these issues, consider implementing the following measures:

• Install panels at the recommended 21-degree tilt to facilitate natural cleaning by rainwater
• Use self-cleaning panel technologies or schedule regular cleaning, especially during drier months
• Employ robust mounting systems to withstand occasional strong winds or storms

Overall, Cerquilho presents an excellent location for solar PV installations, with consistent year-round production and manageable environmental challenges. The tropical climate and relatively stable seasonal variations make it an ideal site for harnessing solar energy throughout the year.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 21° North in Cerquilho, Brazil

To maximize your solar PV system's energy output in Cerquilho, Brazil (Lat/Long -23.1911, -47.7734) 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 Cerquilho, 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 Cerquilho, 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	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 Cerquilho, 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 Cerquilho, 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 Cerquilho, Brazil

The topography around Cerquilho, Brazil, is characterized by gently rolling hills and low-lying plains. This region, located in the state of São Paulo, is part of the larger Atlantic Plateau, which extends across much of southeastern Brazil. The landscape is a mix of agricultural lands, scattered patches of remnant Atlantic Forest, and urban areas. The terrain in and around Cerquilho is generally undulating, with elevations ranging from about 500 to 600 meters above sea level. The area is drained by several small rivers and streams, including the Sorocaba River, which flows near the city. These waterways have carved shallow valleys into the landscape over time, creating a subtle interplay of slopes and flatlands.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat or gently sloping areas with good sun exposure throughout the day. These conditions are generally met in the agricultural lands surrounding Cerquilho. The open fields and pastures to the north and east of the city offer promising potential for solar PV development. These areas typically have fewer obstructions that could cast shadows on solar panels, such as tall buildings or dense forests. The gentle slopes in these regions can also be advantageous, as they can be oriented to maximize sunlight capture throughout the day. Another potentially suitable area lies to the southwest of Cerquilho, where there are expansive agricultural lands with minimal urbanization. This region's topography is relatively flat, making it easier and more cost-effective to install large arrays of solar panels. It's important to note that while the topography in these areas is generally favorable for solar PV, other factors such as land ownership, proximity to power infrastructure, and environmental considerations would also need to be taken into account when planning large-scale solar installations. Additionally, detailed site surveys would be necessary to determine the most optimal locations within these broader areas.
