Caconde, São Paulo, Brazil presents a good to excellent location for year-round solar PV energy generation. The consistent tropical climate and reliable sunlight make this area well-suited for solar installations throughout all seasons.

Seasonal Solar Performance

The solar energy output at Caconde shows strong performance across all seasons, with summer delivering the highest production at 6.36 kWh per day per kW of installed capacity. Spring follows closely with 6.02 kWh/day, while autumn maintains solid output at 5.62 kWh/day. Even during winter, the location still produces a respectable 5.05 kWh/day per kW. Summer and spring emerge as the ideal seasons for solar generation at this location, offering the peak energy production periods. However, the relatively modest seasonal variation means that solar panels will generate substantial electricity year-round, making this an attractive location for consistent energy production.

Optimal Installation Configuration

For maximum year-round energy production at Caconde, São Paulo, solar panels should be installed at a fixed tilt angle of 20 degrees facing North. This optimal angle is calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance data to maximize total annual output.

Environmental and Weather Considerations

Several local factors could potentially impact solar production at Caconde and should be addressed during installation:

• Tropical rainfall patterns: Heavy seasonal rains can reduce solar output and create debris accumulation on panels
• High humidity levels: Can lead to moisture-related equipment issues and reduced panel efficiency
• Dust and vegetation growth: Rapid plant growth in tropical climates can create shading issues
• Intense UV exposure: Can accelerate equipment degradation over time

Preventative Installation Measures

To maximize energy production despite these challenges, several preventative measures should be implemented: Proper drainage and ventilation systems are essential to handle heavy rainfall and high humidity. Installing panels with adequate spacing allows air circulation and prevents moisture buildup that could damage electrical components. Regular maintenance scheduling becomes particularly important in tropical locations. This includes frequent panel cleaning to remove accumulated dust, debris, and any organic matter that could block sunlight. Establishing clear sight lines and trimming vegetation regularly prevents shading issues. Quality equipment selection makes a significant difference in tropical environments. Choose panels and inverters specifically rated for high humidity and temperature conditions, with robust weatherproofing and corrosion-resistant materials. Monitoring systems should be installed to track performance and quickly identify any drops in efficiency that might indicate cleaning needs or equipment issues. This proactive approach helps maintain optimal energy production throughout the year. Despite these considerations, Caconde's consistent solar resource and favorable climate make it an excellent location for solar PV installations when proper planning and maintenance practices are implemented.

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

Seasonal solar PV output for Latitude: -21.542, Longitude: -46.6252 (Caconde, 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 20° North in Caconde, Brazil

To maximize your solar PV system's energy output in Caconde, Brazil (Lat/Long -21.542, -46.6252) throughout the year, you should tilt your panels at an angle of 20° 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 Caconde, 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 Caconde, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
6° North in Summer	27° North in Autumn	37° North in Winter	15° 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 Caconde, 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 Caconde, 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 Caconde, Brazil

Topographical Features Around Caconde

Caconde sits in the northeastern region of São Paulo state, positioned within the Brazilian Highlands at an elevation of approximately 870 meters above sea level. The surrounding landscape is characterized by rolling hills and undulating terrain typical of the Serra da Mantiqueira mountain range system. This elevated plateau region features a mix of gentle slopes and steeper hillsides, with the topography gradually rising toward the northeast as it approaches the border with Minas Gerais state.

The area displays a predominantly hilly terrain with numerous small valleys carved by seasonal streams and tributaries. The elevation varies considerably across the region, ranging from around 700 meters in the lower valleys to over 1,200 meters on the highest ridgelines. The landscape is punctuated by rounded hilltops and broad ridges that have been shaped by millions of years of erosion, creating a relatively mature topographical profile with less dramatic elevation changes than younger mountain systems.

Local drainage patterns flow primarily toward the southwest, eventually feeding into the Pardo River system. The terrain slopes are generally moderate, though some areas feature steeper gradients where harder rock formations have resisted erosion more effectively. Agricultural activities have modified much of the natural landscape, with terraced fields and cleared areas creating a patchwork of land uses across the rolling countryside.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations around Caconde would be the broad, south-facing slopes and relatively flat ridge tops that characterize much of the regional topography. These elevated areas offer several advantages, including reduced atmospheric interference due to altitude and typically fewer obstructions from vegetation or structures that might create shading issues.

The gently rolling plateau areas to the south and southwest of Caconde present particularly favorable conditions for large solar arrays. These locations feature moderate slopes that can be easily graded for optimal panel positioning while maintaining good drainage characteristics. The terrain in these areas is stable, with well-consolidated soils that can support the infrastructure requirements of major solar installations without extensive foundation work.

Ridge systems running roughly east-west provide excellent opportunities for solar development, as their southern exposures can be utilized effectively while their elevation offers clear sight lines to the sun throughout most of the day. Areas with slopes between 5 and 15 degrees toward the south would be ideal, as they naturally provide good panel orientation while facilitating construction and maintenance access.

The cleared agricultural lands on broader valley floors also present opportunities for solar development, particularly where the terrain is relatively level and already cleared of native vegetation. These areas often have existing road access and electrical infrastructure that could support solar installations, though careful consideration would need to be given to local drainage patterns during the rainy season.

Areas to avoid would include the steeper hillsides with gradients exceeding 20 degrees, narrow valleys prone to morning fog or afternoon shadows, and locations with unstable soils or significant erosion issues. The most challenging terrain lies in the deeply incised valleys and on the steepest slopes of the higher ridgelines, where construction would be difficult and the risk of equipment damage from erosion or landslides would be elevated.
