Ubaitaba, Bahia, Brazil presents a highly favorable location for year-round solar energy generation. This tropical location consistently delivers strong solar output across all seasons, making it an excellent choice for solar PV installations.

Seasonal Solar Performance

The solar energy production at Ubaitaba shows impressive consistency throughout the year. Autumn delivers the highest output at 5.95kWh per day per kW of installed solar capacity, closely followed by spring at 5.90kWh per day. Summer provides 5.68kWh per day, while winter shows the lowest but still substantial production at 4.67kWh per day. The best times for solar generation at this location are during autumn and spring months, when the sun's angle provides optimal conditions for energy production. Even during the winter season, the output remains quite strong due to the tropical location's advantageous position relative to the sun's path. For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 14 degrees facing north. This optimal angle takes into account the location's latitude and the sun's seasonal variations to maximize total annual output.

Environmental Factors and Mitigation Strategies

Several environmental factors in this tropical region could potentially impact solar energy production: High Humidity and Moisture The tropical climate brings elevated humidity levels that can cause corrosion of electrical components and reduce panel efficiency over time. Installing panels with robust anti-corrosion coatings and ensuring proper ventilation behind panels helps combat moisture-related issues. Heavy Rainfall During Wet Season Intense tropical rainfall can temporarily reduce solar output and may cause water damage if systems aren't properly sealed. Using high-quality weatherproof mounting systems and ensuring proper drainage around installations prevents water accumulation and damage. Dust and Debris Accumulation Tropical environments often generate significant dust and organic debris that can accumulate on panel surfaces, reducing efficiency. Regular cleaning schedules and installing panels at appropriate angles to encourage natural cleaning by rainfall helps maintain optimal performance. Potential Storm Activity Tropical regions may experience severe weather events that could damage solar installations. Using reinforced mounting systems rated for high wind loads and ensuring proper grounding protects against storm damage and electrical surges. Overall, Ubaitaba offers excellent conditions for solar energy generation, and with proper installation techniques and maintenance practices, these environmental challenges can be effectively managed to ensure reliable, high-output solar performance year-round.

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

Seasonal solar PV output for Latitude: -14.271, Longitude: -39.384 (Ubaitaba, 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 14° North in Ubaitaba, Brazil

To maximize your solar PV system's energy output in Ubaitaba, Brazil (Lat/Long -14.271, -39.384) throughout the year, you should tilt your panels at an angle of 14° 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 Ubaitaba, 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 Ubaitaba, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° 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.

Calculate solar panel row spacing in Ubaitaba, 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 Ubaitaba, Brazil.

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 Ubaitaba, Brazil

Topography Around Ubaitaba

Ubaitaba sits in the southern region of Bahia state, Brazil, nestled within the Atlantic Forest biome along the country's eastern coast. The terrain around this municipality is characterized by rolling hills and gentle undulations that are typical of the coastal mountain ranges of southeastern Bahia. The landscape features a mix of moderate elevations, with the town itself positioned at approximately 200 meters above sea level.

The topography transitions from the coastal lowlands to the east toward more pronounced hillsides and ridges as one moves inland to the west. These hills are part of the broader Serra do Mar mountain system, though in this region they present as more subdued formations rather than dramatic peaks. The terrain is dissected by numerous small valleys and waterways that drain eastward toward the Atlantic Ocean, creating a gently rolling landscape with varied microtopography.

The vegetation coverage consists primarily of Atlantic Forest remnants interspersed with agricultural lands, particularly cacao plantations and pastures. This mixed land use has created a patchwork landscape where forested areas alternate with cleared agricultural zones. The climate in this region is tropical, with distinct wet and dry seasons that influence both the natural vegetation patterns and agricultural practices.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Ubaitaba would be found on the gentler slopes and plateau areas that offer relatively flat terrain with good southern exposure. The cleared agricultural lands, particularly former pasture areas, present excellent opportunities for solar development as they require minimal additional clearing and often have existing access infrastructure.

Areas to the north and northwest of Ubaitaba town center appear particularly promising, where the terrain levels out into broader, more stable surfaces. These locations benefit from reduced grading requirements and lower development costs compared to steeper hillsides. The existing road network in these areas, developed to support agricultural activities, provides good access for construction and maintenance operations.

The elevated positions throughout the region offer advantages for solar installations, as they typically experience better air circulation and reduced atmospheric moisture compared to lower-lying areas. This elevation also helps minimize potential issues with ground moisture and flooding during the wet season. Former cacao plantation areas that have been converted to pasture or left fallow represent particularly attractive sites, as they often feature gentle slopes with good drainage characteristics.

Areas closer to existing electrical transmission infrastructure would be most practical for large-scale development, as connection costs represent a significant portion of project economics. The flatter agricultural zones that lie between the more pronounced hills offer the best combination of suitable topography, existing land use patterns, and infrastructure access for utility-scale solar photovoltaic projects.
