Vera Cruz, Bahia, Brazil, located at latitude -13.0255 and longitude -38.7091, offers a promising environment for solar energy generation throughout the year. Situated in the tropics, this location benefits from consistent sunlight and experiences seasons primarily characterized by wet and dry periods rather than significant temperature fluctuations.

Seasonal Solar Performance

The solar energy potential in Vera Cruz demonstrates relatively stable output across seasons, with some variations:

• Summer: 6.58 kWh/day
• Autumn: 6.04 kWh/day
• Winter: 4.81 kWh/day
• Spring: 6.33 kWh/day

These figures represent the expected daily electricity output per kilowatt of installed solar capacity.

Optimal Generation Periods

The most favorable times for solar energy production in Vera Cruz are during summer and spring, with autumn also showing strong potential. Winter experiences a slight dip in output but still maintains a respectable level of energy generation. This consistency makes Vera Cruz an excellent location for year-round solar power production.

Panel Tilt Optimization

For fixed panel installations in Vera Cruz, Bahia, the ideal tilt angle to maximize year-round solar production is 12 degrees facing North. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and Earth's elliptical orbit to ensure optimal energy capture throughout the year.

Environmental Considerations

While Vera Cruz generally offers favorable conditions for solar energy production, there are a few environmental factors to consider: 1. Humidity: The tropical climate can lead to high humidity levels, potentially affecting panel efficiency. Regular cleaning and maintenance can mitigate this issue. 2. Rainfall: During the wet season, increased cloud cover may temporarily reduce solar output. However, the rain can also help keep panels clean, which is beneficial in the long run. 3. Coastal location: Proximity to the ocean may expose panels to salt spray, which can cause corrosion over time. Using corrosion-resistant materials and applying protective coatings can help prevent damage.

Overall, these factors are not significant enough to deter solar installation in Vera Cruz. With proper planning and maintenance, solar PV systems can perform excellently in this location, taking advantage of the consistent tropical sunlight throughout the year.

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 Vera Cruz

Seasonal solar PV output for Latitude: -13.0255, Longitude: -38.7091 (Vera Cruz, 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 12° North in Vera Cruz, Brazil

To maximize your solar PV system's energy output in Vera Cruz, Brazil (Lat/Long -13.0255, -38.7091) throughout the year, you should tilt your panels at an angle of 12° 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 Vera Cruz, 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 Vera Cruz, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° South in Summer	18° North in Autumn	28° North in Winter	7° 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 Vera Cruz, 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 Vera Cruz, 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 Vera Cruz, Brazil

The topography around Vera Cruz, Brazil, located at approximately 13.0255°S and 38.7091°W, is characterized by a diverse landscape that includes coastal features and inland terrain. This region is situated on the eastern coast of Brazil, in the state of Bahia, and is part of the larger Salvador metropolitan area. The immediate coastal area of Vera Cruz is relatively flat, with sandy beaches and low-lying coastal plains. As you move inland, the terrain gradually becomes more varied, with gentle hills and undulating landscapes. The region is part of the Atlantic Forest biome, which historically covered much of Brazil's eastern coast. However, much of the original forest has been cleared for agriculture and urban development.

Coastal Features

The coastline near Vera Cruz is marked by beautiful beaches, small bays, and estuaries. The area is known for its mangrove swamps, which provide important ecological habitats. Offshore, there are several small islands that are part of the municipality of Vera Cruz, including Ilha de Itaparica, which is connected to the mainland by a bridge.

Inland Topography

Moving away from the coast, the land gradually rises, forming a series of low hills and plateaus. These areas are typically covered with a mix of grasslands, shrubs, and patches of secondary forest. The soil in this region is often sandy or clay-like, influenced by the coastal environment and the underlying geological formations.

Potential for Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would have the following characteristics: 1. Flat or gently sloping terrain: The inland areas just beyond the coastal plains, where the landscape begins to rise into low hills, could provide suitable sites. These areas often have enough elevation to avoid flooding risks while still offering relatively flat surfaces for solar panel installation. 2. Open spaces with minimal shading: Agricultural lands or cleared areas that are not currently in use for farming or urban development would be prime candidates. These spaces typically receive ample sunlight throughout the day. 3. Proximity to existing infrastructure: Areas near major roads or power lines would be advantageous for connecting the solar installations to the grid and facilitating maintenance access. 4. Away from environmentally sensitive areas: It would be important to avoid mangrove swamps, remaining patches of Atlantic Forest, and other ecologically important zones. 5. Elevated areas with good exposure: Some of the higher ground in the region, particularly on the western side of Ilha de Itaparica or the mainland areas northwest of Vera Cruz, could offer excellent solar exposure and minimal risk of coastal flooding. Given these considerations, the most promising areas for large-scale solar PV installations would likely be found in the cleared inland regions to the west and northwest of Vera Cruz. These areas often have the right combination of topography, available land, and infrastructure access to support significant solar energy development while minimizing environmental impact.
