Solar Energy Potential in Francisco Morato, Brazil
Francisco Morato, located in the state of São Paulo, Brazil, offers a reasonably favorable location for solar energy generation throughout the year. Situated in the tropical region at coordinates -23.2683, -46.7092, this area benefits from relatively consistent sunlight patterns typical of tropical climates, where seasonal variations are more defined by rainfall than by significant changes in daylight hours. The solar energy production potential varies across the meteorological seasons, with the highest output occurring during summer months at 6.05kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.32kWh/day, while autumn generates approximately 5.07kWh/day. Winter shows the lowest production at 4.15kWh/day per installed kilowatt, but still maintains reasonable output compared to many non-tropical locations.Seasonal Performance and Optimal Timing
The data reveals that Francisco Morato experiences about a 31% difference between the highest and lowest producing seasons. This relatively moderate seasonal variation is advantageous for year-round solar energy production. Summer (December to February) clearly stands out as the prime period for solar generation, making this an excellent time for energy-intensive activities or for storing excess energy if battery systems are in place. For fixed solar panel installations in this location, the ideal tilt angle to maximize year-round energy production is 21 degrees facing North. This specific angle has been calculated by analyzing daily solar elevation patterns at this latitude, weighted by the location's solar irradiance potential throughout the year, and accounting for Earth's elliptical orbit around the sun.Environmental and Weather Considerations
Several environmental factors could potentially impact solar energy production in Francisco Morato:- Rainfall patterns: As a tropical location, Francisco Morato experiences a distinct wet season (typically October to March), which can reduce solar efficiency due to cloud cover and direct rainfall.
- Air pollution: Proximity to the Greater São Paulo metropolitan area may result in occasional air quality issues that could diminish solar irradiance.
- Vegetation growth: The region's lush vegetation and rapid plant growth may create shading issues if not properly managed.
Preventative Measures for Optimal Production
To maximize solar energy production despite these potential challenges, several preventative measures are recommended during installation and maintenance: Install panels slightly higher than standard height to reduce potential shading from rapidly growing vegetation. Regular trimming of surrounding trees and plants is also essential to prevent shading as the seasons progress. Include a robust cleaning system or schedule to address dust accumulation, which can be significant during the dry season, and pollen deposits during flowering periods. Self-cleaning systems or hydrophobic coatings can be particularly beneficial. Consider micro-inverters or power optimizers rather than string inverters, as these technologies help minimize production losses when some panels are partially shaded or affected by localized cloud cover, which is common during the wet season. Despite these considerations, Francisco Morato remains a viable location for solar energy production, with its year-round solar potential making it suitable for residential, commercial, and utility-scale installations.Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 21° North in Francisco Morato, Brazil
To maximize your solar PV system's energy output in Francisco Morato, Brazil (Lat/Long -23.2683, -46.7092) 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 Francisco Morato, 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 Francisco Morato, 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 | 17° 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 Francisco Morato, Brazil

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Francisco Morato, Brazil
Francisco Morato, located in the state of São Paulo, Brazil, sits within a region characterized by undulating to hilly terrain. The topography around this municipality is largely defined by its position in the Atlantic Plateau region, with elevations generally ranging from 750 to 900 meters above sea level. The landscape features a series of rolling hills, valleys, and ridgelines that are typical of southeastern Brazil's highland areas. The area exhibits significant topographical variation, with steeper slopes in the northern and western portions of the municipality. Several small rivers and streams cut through these hills, creating a network of narrow valleys. The Serra da Cantareira mountain range influences the broader regional topography, creating a somewhat rugged landscape in parts of the surrounding area.
Vegetation and Land Cover
The natural vegetation of the region consists primarily of Atlantic Forest remnants, though much of the original forest has been cleared for urban development and agriculture. The remaining forest patches tend to be concentrated on steeper slopes and protected areas. The combination of hills, forest fragments, and developed areas creates a mosaic landscape pattern typical of the periphery of the São Paulo metropolitan region.Solar PV Potential Areas
For large-scale solar photovoltaic (PV) installations, several factors must be considered beyond just topography, including solar radiation, land availability, grid connectivity, and environmental constraints. However, focusing primarily on topographical considerations, the most suitable areas near Francisco Morato would include: The flatter plateaus and gentle slopes to the south and southeast of Francisco Morato offer more favorable conditions for large-scale solar installations. These areas generally have gradients below 10 degrees, which is preferable for minimizing installation costs and maximizing panel efficiency. Specifically, portions of neighboring Franco da Rocha and Caieiras have some relatively level areas that could be suitable. The eastern sections toward Mairiporã contain some elevated plateaus with good solar exposure, though careful site selection would be necessary to avoid the steeper slopes that characterize much of this area. These higher elevation sites often benefit from reduced fog and haze compared to valley locations.Challenges and Considerations
It's important to note that the entire region around Francisco Morato presents certain challenges for large-scale solar development. The hilly terrain means that truly flat, extensive tracts of land are limited. Additionally, the proximity to the São Paulo metropolitan area means that much of the flatter land is already urbanized or designated for development. The region also experiences a humid subtropical climate with occasional cloudy conditions, which can affect solar efficiency. The combination of topographical constraints and the region's high population density suggests that medium-scale installations on suitable hillsides or repurposing of existing developed areas (such as rooftop solar) might be more practical than very large ground-mounted solar farms. Environmental considerations are also significant, as remaining Atlantic Forest fragments are protected by Brazilian law, and clearing these areas for solar development would face regulatory hurdles and ecological concerns.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
