Solar Energy Potential in Prado, Brazil

Prado, Brazil offers a promising location for solar energy generation, situated in a tropical region where sunlight remains fairly consistent throughout the year. This coastal town in Bahia state shows strong solar potential across all seasons, though with some natural variation. The solar energy output in Prado demonstrates good year-round performance. During summer months, solar panels can generate approximately 5.97 kWh per day for each kilowatt of installed capacity. Autumn remains strong with 5.66 kWh/day, while spring delivers a similar 5.51 kWh/day. Winter shows the lowest production at 4.54 kWh/day, but still maintains respectable output compared to many other global locations.

Seasonal Variations and Optimal Production Periods

The data reveals that summer (December-February) represents the peak production period in Prado, which aligns with expectations for a Southern Hemisphere location. The relatively small difference between summer and autumn production (only about 5%) indicates consistent solar potential through half the year. Winter months show approximately 24% lower output compared to summer, representing the most significant seasonal variation. However, even during this "low" season, the 4.54 kWh/day figure remains substantial for solar energy production. For maximizing solar energy capture in Prado, fixed solar panels should be installed at a 16-degree tilt facing North. This specific angle has been calculated to optimize year-round energy production based on Prado's geographical position and seasonal solar patterns.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Prado:

• Coastal humidity and salt exposure can gradually degrade solar panels and electrical components if not properly protected.
• The region's wet season (typically November through April) may bring increased cloud cover that temporarily reduces solar output.
• Tropical vegetation growth can create shading issues if not regularly maintained around ground-mounted installations.

To mitigate these challenges, solar installations in Prado should incorporate marine-grade components with enhanced corrosion resistance. Regular cleaning schedules are advisable to remove salt deposits and maintain optimal panel efficiency. Additionally, strategic placement away from tall vegetation or implementing routine maintenance to prevent shading will help maximize energy capture. The relatively minimal seasonal variation makes Prado an excellent candidate for solar energy systems, as it provides more consistent year-round production compared to locations at higher latitudes where winter output often drops dramatically.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

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

Seasonal solar PV output for Latitude: -17.1182, Longitude: -39.3495 (Prado, 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 16° North in Prado, Brazil

To maximize your solar PV system's energy output in Prado, Brazil (Lat/Long -17.1182, -39.3495) throughout the year, you should tilt your panels at an angle of 16° 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 Prado, 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 Prado, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° North in Summer	23° North in Autumn	33° North in Winter	11° 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 Prado, 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 Prado, 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 Prado, Brazil

The terrain surrounding Prado, Brazil showcases a diverse topographical profile characteristic of Brazil's eastern coastal region. Located in the state of Bahia at approximately 17.12°S, 39.35°W, Prado sits where the Atlantic coastal plains meet more elevated inland territories. The immediate coastal area features relatively flat to gently undulating terrain, with sandy beaches and occasional coastal cliffs. Moving inland, the landscape gradually transitions to rolling hills and plateaus, with elevations typically ranging from near sea level along the coast to approximately 150-200 meters in the inland areas. The region contains a network of rivers and streams, including the Jucuruçu River, which create natural valleys and drainage systems throughout the landscape. These waterways have shaped the local topography, carving gentle depressions and creating alluvial plains in certain areas. Vegetation coverage varies from coastal restinga (sandy coastal forest) to patches of Atlantic Forest remnants and agricultural lands, influencing the visual character of the topography.

Solar PV Suitability

For large-scale solar photovoltaic development, the inland elevated plateaus west of Prado present the most promising opportunities. These areas offer several advantages for solar energy installation. The slightly higher elevation plateaus, approximately 10-15 kilometers inland from the coast, benefit from reduced maritime influence, resulting in less cloud cover compared to immediate coastal locations. These inland plateaus typically feature more consistent solar radiation patterns throughout the year. The gently rolling terrain of these plateaus provides relatively flat expanses that would minimize grading requirements during construction while still offering sufficient slope for natural drainage—an important consideration for maintaining solar array infrastructure. Additionally, these areas tend to have less dense vegetation compared to forest-covered regions, potentially reducing land clearing requirements and associated environmental impacts. Areas to the northwest of Prado, where the landscape opens into broader plateaus with fewer waterways intersecting the terrain, offer particularly suitable conditions. These locations combine favorable topography with good accessibility via existing road networks, facilitating both construction and ongoing maintenance operations for solar facilities. The coastal plains, while flat and seemingly suitable, may face challenges from higher humidity, salt exposure, and potential flood risk during extreme weather events. Similarly, areas with steeper slopes or dense forest coverage would present significant installation challenges and higher environmental impacts. For optimal solar PV development, focus should be directed toward the inland plateaus where topographical conditions, solar exposure, and practical development considerations align most favorably.
