Ibirapitanga, Bahia, Brazil presents a highly favorable location for year-round solar PV energy generation. Located in the tropical zone at coordinates -14.0589, -39.4082, this region benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods than traditional temperature variations.

Solar Energy Production Potential

The solar output data demonstrates excellent energy generation capacity across all seasons. Autumn delivers the highest production at 5.95 kWh per day per kW of installed solar capacity, closely followed by spring at 5.90 kWh per day. Summer produces 5.68 kWh per day, while winter shows the lowest but still substantial output at 4.67 kWh per day. The most productive periods for solar generation occur during autumn and spring months, when atmospheric conditions and sun angles combine optimally. Even the winter months maintain strong production levels, making this location exceptionally well-suited for consistent year-round solar energy harvesting. For fixed panel installations at this location, the ideal tilt angle is 13 degrees North to maximize total annual production. This angle calculation accounts for the site's latitude, daily solar elevation angles throughout the year, and weights these factors based on actual solar irradiance data to optimize overall energy output.

Environmental and Weather Challenges

Several local factors could potentially impact solar production efficiency in this tropical Brazilian location:

• Heavy rainfall during wet season: Intense tropical downpours can reduce solar irradiance and leave water spots or debris on panels
• High humidity levels: Persistent moisture can lead to corrosion of electrical components and reduced panel efficiency
• Dust and vegetation growth: The warm, humid climate promotes rapid plant growth and dust accumulation on panel surfaces
• Salt air exposure: Depending on proximity to the coast, salt corrosion may affect metal components

Preventative Installation Measures

To maximize energy production despite these challenges, several protective measures should be implemented during installation: Regular cleaning systems or easy access for maintenance crews help address dust and debris accumulation. Installing panels with adequate spacing and ventilation reduces moisture-related issues and prevents overheating. Using marine-grade or tropical-rated electrical components and mounting hardware provides enhanced resistance to humidity and potential salt exposure. Proper drainage design prevents water pooling around installation areas, while selecting panel mounting angles that promote natural rainwater runoff helps maintain cleaner surfaces. Additionally, establishing vegetation management protocols around solar installations prevents shading from rapidly growing tropical plants. Despite these considerations, the consistently high solar output figures indicate that Ibirapitanga's tropical location offers excellent conditions for solar PV installations, with proper planning and maintenance protocols easily addressing the environmental challenges.

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

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

Seasonal solar PV output for Latitude: -14.0589, Longitude: -39.4082 (Ibirapitanga, 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 13° North in Ibirapitanga, Brazil

To maximize your solar PV system's energy output in Ibirapitanga, Brazil (Lat/Long -14.0589, -39.4082) throughout the year, you should tilt your panels at an angle of 13° 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 Ibirapitanga, 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 Ibirapitanga, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	20° North in Autumn	30° North in Winter	8° 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.

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 Ibirapitanga, Brazil

Topographical Features of the Ibirapitanga Region

The area surrounding Ibirapitanga in Bahia state presents a varied but generally favorable topographical landscape characterized by rolling hills and gentle undulations typical of Brazil's Atlantic coastal region. This municipality sits within the broader context of the Mata Atlântica (Atlantic Forest) biome transition zone, where the terrain gradually shifts from coastal lowlands toward the interior highlands. The immediate vicinity of Ibirapitanga features predominantly moderate elevation changes, with the landscape consisting of gentle slopes and relatively open areas that have been historically used for agriculture and cattle ranching. The region's topography is punctuated by small valleys and modest ridgelines that create a naturally varied but not dramatically steep terrain profile. Moving inland from Ibirapitanga toward the west and northwest, the landscape begins to show more pronounced elevation changes as it approaches the foothills of the Chapada Diamantina mountain range. These areas feature more significant topographical variation, including steeper slopes and deeper valleys carved by seasonal watercourses.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations in the Ibirapitanga region would be the gently sloping agricultural lands and cleared pasturelands that extend primarily to the south and southeast of the municipality. These areas offer several key advantages including relatively flat to moderately sloping terrain that requires minimal grading for solar panel installation. The cleared agricultural zones present particularly attractive opportunities because they typically feature good road access for construction and maintenance activities, while avoiding the environmental complications associated with clearing native vegetation. Many of these areas have been used for cattle grazing or crop cultivation, meaning the land has already been modified from its natural state and often has established infrastructure connections. Areas with southern-facing slopes of moderate grade would be especially well-suited for solar installations, as they can maximize exposure to direct sunlight throughout the day while maintaining manageable construction and maintenance requirements. The gentle topography in these zones also facilitates proper drainage, which is essential for long-term solar facility operation. The region's relatively stable geological conditions, typical of this part of Bahia's coastal plain, provide a solid foundation for large-scale solar infrastructure. The absence of extreme topographical features such as steep ravines, frequent flooding zones, or unstable soil conditions makes development more straightforward and cost-effective. Areas closer to existing electrical transmission infrastructure would also be preferable for large-scale solar development, as they would reduce the costs and complexity associated with connecting new solar facilities to the regional power grid. The flatter agricultural lands near established transportation corridors typically offer the best combination of suitable topography and infrastructure access.
