Candeal, Bahia, Brazil presents a highly favorable location for year-round solar photovoltaic energy generation. Located in the tropical zone at coordinates -11.895, -39.2039, this region benefits from consistent sunlight throughout most of the year, with seasonal variations primarily driven by wet and dry periods rather than dramatic changes in daylight hours.
Solar Energy Output Performance
The solar energy production data reveals strong performance across all seasons. Summer delivers the highest output at 6.33 kWh per day per kW of installed solar capacity, followed closely by spring at 6.27 kWh/day. Autumn maintains solid production at 6.04 kWh/day, while winter shows the lowest but still respectable output of 4.70 kWh/day per kW installed. The most productive periods for solar generation at Candeal occur during summer and spring months, when energy output exceeds 6.2 kWh/day per kW. Even during the least productive winter season, the location still generates nearly 75% of peak summer output, demonstrating the consistency that makes tropical locations attractive for solar installations.Optimal Panel Configuration
For fixed panel installations at this location, the ideal tilt angle to maximize total year-round solar production is 11 degrees facing North. This relatively shallow angle reflects the location's proximity to the equator and optimizes energy capture throughout the annual solar cycle.Environmental and Weather Challenges
Several environmental factors could potentially impact solar production efficiency in Candeal's tropical climate:- High humidity and moisture: The tropical environment creates conditions that can lead to corrosion of electrical components and degradation of panel materials over time
- Heavy rainfall during wet seasons: While rain can help clean panels naturally, intense tropical downpours may cause temporary shading and reduced output
- Salt air exposure: Depending on proximity to the coast, salt-laden air can accelerate corrosion of metal components and mounting systems
- Dust and organic debris: During dry periods, dust accumulation and falling leaves or organic matter can reduce panel efficiency
Preventative Installation Measures
To maximize energy production and system longevity in Candeal's environment, several protective measures should be implemented:- Marine-grade components: Use corrosion-resistant aluminum frames, stainless steel mounting hardware, and weatherproof electrical enclosures rated for high-humidity environments
- Enhanced drainage design: Install panels with adequate spacing and drainage channels to prevent water pooling and ensure rapid drying after rainfall
- Regular maintenance scheduling: Establish routine cleaning protocols to remove dust, debris, and any organic growth that could shade panels
- Protective coatings: Apply anti-corrosive treatments to mounting structures and use UV-resistant cabling designed for tropical climates
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 11° North in Candeal, Brazil
To maximize your solar PV system's energy output in Candeal, Brazil (Lat/Long -11.895, -39.2039) 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 Candeal, 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 Candeal, 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 | 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 Candeal, 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 Candeal, 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 Candeal, Brazil
Topographical Features Around Candeal
Candeal is situated in the northeastern region of Bahia state, Brazil, within a landscape characterized by gently rolling hills and relatively low elevation terrain. The area sits at approximately 200 meters above sea level, forming part of the broader Bahian coastal plain that extends inland from the Atlantic Ocean. This region experiences a transitional topography between the flat coastal lowlands to the east and the more elevated interior highlands to the west.
The immediate surroundings of Candeal feature undulating terrain with modest elevation changes, creating a series of low ridges and shallow valleys. The landscape is predominantly composed of sedimentary formations that have been weathered over time, resulting in generally stable ground conditions. Small streams and seasonal watercourses meander through the valleys, though the overall drainage pattern is relatively sparse due to the semi-arid climate characteristics of this part of Bahia.
The vegetation in this area consists primarily of caatinga scrubland, a dry forest ecosystem adapted to periodic drought conditions. This natural vegetation creates a relatively open landscape with scattered trees and shrubs, interspersed with areas of grassland and exposed soil during drier periods. The terrain shows evidence of agricultural use, with cleared areas used for livestock grazing and small-scale farming operations.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations around Candeal would be the elevated plateau areas and gently sloping hillsides that offer stable ground conditions and minimal shading throughout the day. These areas typically feature gradual south-facing slopes that would optimize solar panel orientation for maximum energy capture in the Southern Hemisphere.
The relatively flat to gently undulating terrain found on the broader ridgetops provides excellent opportunities for large solar arrays, as these locations avoid the complications of steep grades while maintaining good drainage characteristics. These elevated positions also benefit from consistent air circulation, which helps maintain optimal operating temperatures for photovoltaic equipment.
Areas with minimal existing vegetation cover, particularly those that have been previously cleared for agricultural purposes, present the most cost-effective development opportunities. The sparse caatinga vegetation in many locations means that land preparation requirements would be relatively modest compared to heavily forested regions. Additionally, the stable geological conditions of the sedimentary substrate provide excellent foundations for solar mounting systems.
The proximity to existing road infrastructure connecting to larger regional centers would be another crucial factor in site selection. Areas within reasonable distance of the BR-116 highway corridor or other major transportation routes would facilitate both construction logistics and ongoing maintenance operations. The relatively open terrain also offers advantages for electrical transmission infrastructure, with fewer topographical obstacles to overcome when connecting to the regional power grid.
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.
