Solar Energy Potential in Serra Redonda, Paraíba, Brazil
Serra Redonda, Paraíba, Brazil offers promising conditions for solar energy generation throughout the year. Located in the tropical region where sunlight remains relatively consistent across seasons, this location demonstrates solid potential for photovoltaic (PV) electricity production. The seasonal performance data shows that spring yields the highest daily energy output at 6.76kWh per installed kilowatt of solar capacity. Summer follows closely with 6.23kWh/day, while autumn and winter produce 5.54kWh/day and 5.09kWh/day respectively. This pattern indicates that while there is some seasonal variation, the difference between the best and worst seasons is relatively modest compared to locations at higher latitudes.Optimal Panel Installation
For fixed solar panel installations in Serra Redonda, Paraíba, the ideal tilt angle is 6 degrees facing North. This specific angle has been calculated to maximize year-round energy production based on the location's position relative to the sun's path throughout the year.Environmental and Weather Considerations
Several environmental factors could potentially affect solar production in Serra Redonda:- Heavy rainfall during wet seasons may reduce solar efficiency due to cloud cover and direct precipitation on panels
- High humidity levels typical of tropical regions can create condensation on panels, potentially reducing efficiency
- Dust accumulation, particularly during dry seasons, can gradually decrease panel performance
Preventative Measures
To maximize solar energy production despite these challenges, several preventative measures are recommended:- Install self-cleaning panels or implement regular cleaning schedules, especially during dry seasons when dust accumulation is highest
- Use anti-reflective coatings on panels to improve performance in high humidity conditions
- Consider slightly adjusting the tilt angle beyond the mathematical optimum of 6 degrees to improve natural cleaning from rainfall
- Install robust mounting systems that can withstand potential seasonal storms
- Implement lightning protection systems, as tropical regions often experience electrical storms
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 Serra Redonda
Seasonal solar PV output for Latitude: -7.159, Longitude: -35.6791 (Serra Redonda, 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 6° North in Serra Redonda, Brazil
To maximize your solar PV system's energy output in Serra Redonda, Brazil (Lat/Long -7.159, -35.6791) throughout the year, you should tilt your panels at an angle of 6° 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 Serra Redonda, 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 Serra Redonda, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 13° North in Autumn | 23° North in Winter | 1° 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 Serra Redonda, 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 Serra Redonda, 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 Serra Redonda, Brazil
The topography around Serra Redonda, Brazil presents a diverse landscape characterized by undulating terrain typical of the northeastern Brazilian interior. Located in the state of Paraíba, Serra Redonda sits within the Borborema Plateau region, which features a mix of rolling hills, elevated plateaus, and scattered valleys. The terrain generally ranges from moderately hilly to mountainous, with elevations typically between 400 to 600 meters above sea level. The area exhibits characteristics of the Brazilian Caatinga biome, with predominantly semi-arid conditions. The landscape includes rocky outcroppings that punctuate the terrain, creating natural landmarks throughout the region. Seasonal watercourses cut through the landscape, forming small valleys that contrast with the higher surrounding elevations. The topography has been shaped by centuries of erosion, resulting in rounded hilltops and gradual slopes in many areas.
Optimal Areas for Solar PV Development
For large-scale solar photovoltaic development, the most suitable areas near Serra Redonda would be the elevated plateaus and gently sloping hillsides with southern to western exposures. These locations offer several advantageous characteristics for solar energy capture. The higher elevation plateaus, particularly those extending to the west and southwest of Serra Redonda, provide relatively flat terrain that would minimize grading requirements during construction while maximizing solar exposure. The areas approximately 5-10 kilometers to the west of Serra Redonda present particularly promising conditions, featuring more open terrain with fewer obstructions from the natural vegetation. These zones typically experience less cloud cover compared to the eastern regions, which may occasionally receive more coastal weather influences from the Atlantic. The northern slopes and plateaus also demonstrate strong potential for solar development, offering expansive areas with minimal competing land uses. These locations generally have good drainage characteristics, reducing flood risks that could potentially impact solar infrastructure. The natural contours of these areas would require less extensive site preparation, potentially lowering development costs. Areas to avoid would include the deeper valleys and eastern slopes with more pronounced vegetation, as these locations may experience more shading throughout the day. Similarly, the steeper mountainous sections would present engineering challenges that would likely make solar development less economically viable compared to the more accessible plateau regions.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. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
