Solar Energy Potential in Jacobina, Bahia, Brazil
Jacobina, Bahia, Brazil, located at latitude -11.1479 and longitude -40.4311, presents a favorable location for solar PV energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns, with seasons characterized more by wet and dry periods than significant temperature variations. The solar energy production potential varies somewhat across the meteorological seasons. Spring shows the highest production at 6.17kWh per day for each kilowatt of installed capacity. Summer follows closely with 6.02kWh/day, while autumn maintains strong production at 5.93kWh/day. Winter experiences a noticeable dip to 4.75kWh/day per kilowatt installed, though this still represents good generation capacity compared to many global locations.Optimal Panel Installation
For fixed solar panel installations in Jacobina, Bahia, the ideal tilt angle to maximize year-round energy production is 10 degrees facing North. This specific angle has been calculated by analyzing the solar elevation patterns at this tropical latitude and weighting them according to the daily PV generation potential throughout the year.Seasonal Considerations
Spring and summer represent the peak production periods in Jacobina, Bahia, making these seasons particularly valuable for solar energy generation. The relatively small variation between the highest producing season (spring) and the lowest (winter) indicates a fairly consistent solar resource throughout the year, which is advantageous for reliable energy planning.Environmental and Weather Factors
Several environmental factors could potentially impact solar production in Jacobina:- Dust accumulation during dry seasons can reduce panel efficiency by creating a film that blocks sunlight absorption
- Heavy rainfall during wet seasons may temporarily reduce production and could potentially damage poorly sealed equipment
- High tropical temperatures can slightly decrease panel efficiency, as most solar panels lose efficiency above certain temperature thresholds
Preventative Measures
To maximize solar energy production in Jacobina, Bahia, several preventative measures should be considered:- Install panels with regular cleaning schedules, especially during dry seasons when dust accumulation is highest
- Use quality weatherproof components rated for tropical conditions
- Consider mounting systems that allow for adequate airflow beneath panels to help mitigate efficiency losses from high temperatures
- Install lightning protection systems, as tropical regions often experience thunderstorms
- Use anti-reflective coated panels that perform better in diffuse light conditions during cloudy periods of the wet season
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 10° North in Jacobina, Brazil
To maximize your solar PV system's energy output in Jacobina, Brazil (Lat/Long -11.1479, -40.4311) throughout the year, you should tilt your panels at an angle of 10° 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 Jacobina, 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 Jacobina, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 4° South in Summer | 17° North in Autumn | 26° North in Winter | 5° 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 Jacobina, 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 Jacobina, 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 Jacobina, Brazil
The terrain surrounding Jacobina, Brazil, is characterized by a striking topographical diversity, with the city itself nestled in a valley between two prominent mountain ranges. Located in the northeastern state of Bahia, Jacobina sits at an elevation of approximately 460 meters above sea level, creating a distinctive landscape that transitions between various geological features.
Mountain Ranges and Valleys
The most notable topographical feature around Jacobina is the Serra da Jacobina mountain range, which forms part of the larger Chapada Diamantina region. These mountains create a dramatic backdrop to the east of the city, with peaks rising to heights of over 1,000 meters. The western side of Jacobina is bordered by another significant mountain formation, creating a valley corridor where the urban area has developed. This valley positioning has historically shaped the development of Jacobina, which was initially established as a gold mining settlement in the 17th century. The surrounding mountains not only provided mineral resources but also influenced the local climate and hydrology.Vegetation and Land Cover
The region exhibits a transition between different Brazilian biomes. The natural vegetation around Jacobina includes elements of the Caatinga (a dry shrubland ecosystem typical of Brazil's northeast) and patches of Atlantic Forest remnants at higher elevations. The mountainsides feature varying degrees of vegetation density, with more lush growth occurring in areas with greater moisture retention. Lower elevations and flatter areas have been significantly altered by human activity, with agriculture and livestock raising being important economic activities. This has created a mosaic landscape of natural vegetation interspersed with cultivated fields and pastures.Hydrography
The topography influences the local hydrographic network, with numerous streams and small rivers flowing through the valleys, many originating in the surrounding highlands. The Itapicuru-Mirim River is one of the significant watercourses in the area, flowing through the region and contributing to the broader Itapicuru River basin.Potential Areas for Solar PV Development
For large-scale solar photovoltaic installations, the most suitable areas near Jacobina would be the flatter terrains located to the west and northwest of the city. These areas offer several advantages: The western plains provide relatively flat topography with minimal shading from the mountain ranges, allowing for optimal solar exposure throughout the day. These areas typically have sparser vegetation compared to the eastern mountains, reducing land clearance requirements and environmental impact. Accessibility is another key factor favoring the western regions. The presence of transportation infrastructure, including highways connecting to major urban centers like Salvador, facilitates the construction and maintenance of large solar installations. The northeastern areas beyond the immediate mountain ranges also present viable options for solar development. These regions feature gently rolling terrain with adequate solar exposure and relatively stable soil conditions for mounting solar array foundations.Topographical Challenges
Despite these opportunities, developers must consider certain topographical challenges. The mountainous areas immediately surrounding Jacobina are less suitable for large-scale installations due to steep slopes, difficult access, and increased cloud cover at higher elevations. Seasonal variations in rainfall can also affect certain low-lying areas, particularly during the rainy season (typically November to April), potentially causing localized flooding in some valley bottoms. This necessitates careful site selection with proper drainage considerations. The semi-arid climate of the broader region does present an advantage for solar energy generation, with minimal cloud cover throughout much of the year, particularly in the drier western areas. This climate pattern, combined with the available flat terrain west of the mountains, creates favorable conditions for solar PV development at scale.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]
Are there incentives for businesses to install solar in Brazil?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power. These include reduced import taxes on solar equipment, accelerated depreciation of investments in renewable energy projects, and preferential financing from public banks. Additionally, some states offer additional incentives such as subsidies or grants for businesses that install solar systems.
