Ibipeba, Brazil represents an excellent location for year-round solar energy generation, with consistently high electricity output throughout all seasons. Located in the tropical region at coordinates -11.4978, -42.1908, this area benefits from the reliable sunlight patterns typical of tropical climates.
Solar Energy Production Performance
The solar energy output at Ibipeba demonstrates remarkable consistency across all meteorological seasons. Spring emerges as the peak production period, generating 7.01kWh per day for each kilowatt of installed solar capacity. Summer and autumn maintain nearly identical high performance levels at 6.50kWh/day and 6.46kWh/day respectively. Even during winter, the lowest production season, output remains strong at 6.20kWh/day per kilowatt installed. This minimal seasonal variation makes Ibipeba particularly attractive for solar installations, as energy production remains predictable and substantial throughout the entire year. The difference between the highest and lowest producing seasons is less than 15%, indicating exceptional stability for solar energy planning.Optimal Panel Configuration
For maximum year-round energy production at this location, solar panels should be installed at a fixed tilt angle of 11 degrees facing North. This optimal angle has been calculated by analyzing daily solar elevation angles at this specific latitude, determining daily optimal panel positioning, and weighting these angles according to solar irradiance data while accounting for Earth's elliptical orbit around the sun.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production at Ibipeba and require careful consideration during installation planning. Dust and Particulate Accumulation: The semi-arid climate characteristic of this region of Bahia can lead to significant dust buildup on solar panels, particularly during dry seasons. This accumulation can reduce panel efficiency by blocking sunlight from reaching photovoltaic cells. Seasonal Rainfall Patterns: While the wet season provides natural panel cleaning, the dry season can extend for several months, allowing substantial dust accumulation. The tropical climate's distinct wet and dry seasons create periods of both natural cleaning and potential soiling. High Temperature Effects: Tropical temperatures can cause solar panels to operate at elevated temperatures, which typically reduces their efficiency compared to cooler conditions.Preventative Measures for Optimal Performance
Several strategies can help maximize solar energy production despite these environmental challenges:- Install automated cleaning systems or schedule regular manual cleaning, particularly during extended dry periods
- Design panel mounting systems with adequate ventilation to promote air circulation and cooling
- Select solar panels with good high-temperature performance coefficients
- Consider anti-soiling coatings on panel surfaces to reduce dust adhesion
- Implement monitoring systems to track performance and identify when cleaning is needed
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 11° North in Ibipeba, Brazil
To maximize your solar PV system's energy output in Ibipeba, Brazil (Lat/Long -11.4978, -42.1908) 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 Ibipeba, 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 Ibipeba, 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 |
|---|---|---|---|
| 4° South in Summer | 18° North in Autumn | 27° 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 Ibipeba, 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 Ibipeba, 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 Ibipeba, Brazil
Topographical Features of the Ibipeba Region
The area surrounding Ibipeba in Bahia state, Brazil, is characterized by gently rolling terrain typical of the Caatinga biome. This semi-arid landscape features relatively low elevation changes, with the town itself situated at approximately 450 meters above sea level. The topography consists primarily of undulating plains interspersed with scattered low hills and occasional rocky outcrops that are characteristic of the Brazilian northeast interior. The terrain gradually rises and falls in gentle waves across the landscape, creating natural drainage patterns that flow toward larger river systems in the region. These elevation changes are generally modest, rarely exceeding 100-200 meters in variation across typical project-sized areas. The soil composition includes weathered crystalline basement rock covered by relatively thin layers of sediment, which creates stable foundation conditions for infrastructure development. Vegetation in the area is sparse due to the semi-arid climate, consisting mainly of drought-resistant shrubs, cacti, and small trees typical of the Caatinga ecosystem. This natural vegetation pattern creates an open landscape with minimal shading concerns and relatively easy land clearing requirements for development projects.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Ibipeba are the broad, gently sloping plateaus that extend to the north and west of the town. These areas offer several advantages including minimal grading requirements, stable geological conditions, and natural drainage that prevents water accumulation during the rainy season. The relatively flat expanses located approximately 10-15 kilometers northwest of Ibipeba present particularly attractive development opportunities. These areas feature consistent gentle slopes of less than 5 degrees, which are ideal for solar panel installation while still providing adequate drainage. The terrain in these locations requires minimal earthwork preparation, significantly reducing construction costs and environmental impact. Areas to the southwest also show promise, where the landscape opens into broader valleys between low ridges. These locations benefit from natural wind patterns that help keep solar panels cool and reduce dust accumulation. The stable, well-drained soils in these areas provide excellent foundations for mounting systems and electrical infrastructure. The eastern approaches to Ibipeba tend to be slightly more undulating and may require more extensive site preparation. However, several plateau areas in this direction still offer viable development sites, particularly where the terrain levels out into broader expanses suitable for large arrays. When selecting specific sites, developers should prioritize areas with consistent southern exposure on gentle slopes, avoiding locations in natural drainage channels or areas prone to seasonal flooding. The region's generally stable geological conditions and sparse vegetation make most suitable topographical areas relatively straightforward to develop for solar installations.Brazil solar PV Stats as a country
