Feira de Santana, Brazil, located at latitude -12.2619 and longitude -38.9702, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.
Seasonal Solar Performance
Solar panel performance in Feira de Santana demonstrates strong potential across all seasons. Summer yields the highest output at 6.21 kWh per day for each kilowatt of installed capacity. Spring follows closely with 6.00 kWh/day, while autumn produces 5.60 kWh/day. Even during winter, the least productive season, panels still generate a respectable 4.52 kWh/day. The relatively small variation between seasons indicates that Feira de Santana is well-suited for year-round solar energy production. The most ideal times for generation are during summer and spring, but the consistent output suggests that solar installations can be beneficial throughout the entire year.Optimal Panel Tilt
For fixed solar panel installations in Feira de Santana, the ideal tilt angle to maximize year-round energy production is 11 degrees facing North. This angle takes into account the location's proximity to the equator and the sun's path throughout the year, ensuring optimal exposure to sunlight across all seasons.Environmental Considerations
While Feira de Santana's climate is generally favorable for solar energy production, there are a few factors to consider: 1. Rainfall: The region experiences a wet season, which could temporarily reduce solar output due to cloud cover. 2. Dust and pollen: Being in a tropical area, accumulation of dust and pollen on panels may occur. To mitigate these issues, installing panels at the recommended tilt angle helps with natural cleaning during rainfall. Regular maintenance and cleaning schedules should be implemented to address dust and pollen buildup. Additionally, using high-quality, weather-resistant panels can help ensure consistent performance in varying weather conditions. Overall, Feira de Santana presents an excellent location for solar PV installations, with strong potential for energy generation throughout the year and minimal environmental challenges to overcome.Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 11° North in Feira De Santana, Brazil
To maximize your solar PV system's energy output in Feira De Santana, Brazil (Lat/Long -12.2619, -38.9702) throughout the year, you should tilt your panels at an angle of 11° 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 Feira De Santana, 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 Feira De Santana, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 3° South in Summer | 18° North in Autumn | 28° North in Winter | 6° 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 Feira De Santana, 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 Feira De Santana, 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 Feira De Santana, Brazil
The topography around Feira de Santana, Brazil, is characterized by a mix of gently rolling hills and flat plains. This region, located in the northeastern state of Bahia, sits at an elevation of approximately 230 meters above sea level. The landscape is part of the larger Brazilian Highlands, which gradually slope down towards the Atlantic coast to the east. The area surrounding Feira de Santana features a semi-arid climate, with vegetation transitioning from the more lush Atlantic Forest in the east to the drier Caatinga biome in the west. This gradual change in ecosystems is reflected in the topography, with the terrain becoming slightly more rugged and elevated as one moves inland. To the north and west of Feira de Santana, the land becomes increasingly arid, with scattered rock formations and sparse vegetation. The soil in these areas tends to be thin and less fertile, making them less suitable for agriculture but potentially ideal for other land uses.
Potential Areas for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Feira de Santana, several factors come into play. The semi-arid climate of the region, with its abundant sunshine and relatively low cloud cover, makes it generally favorable for solar energy production. The areas to the north and west of Feira de Santana would likely be most suited for large-scale solar PV projects. These regions typically have: 1. Flatter terrain, which simplifies construction and reduces costs associated with land preparation. 2. Lower agricultural value, minimizing conflicts with food production. 3. Sparser vegetation, reducing the need for land clearing. 4. Higher solar irradiance due to their more arid nature and reduced cloud cover. Specific locations that might be particularly suitable include the municipalities of Santa Bárbara, Tanquinho, and Anguera. These areas have expanses of relatively flat land that receive ample sunlight throughout the year. It's important to note that while these areas may be topographically and climatically suitable, other factors such as proximity to electrical infrastructure, land ownership, and environmental considerations would need to be carefully evaluated before embarking on any large-scale solar PV project.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.
