Solar Energy Potential in Fagundes, Paraíba, Brazil

Fagundes, Paraíba, located in Brazil at latitude -7.355 and longitude -35.775, offers promising conditions for solar energy generation throughout the year. Situated in the tropics, this location benefits from relatively consistent sunlight patterns, with seasonal variations defined more by rainfall than by significant changes in daylight duration. The solar electricity production potential in Fagundes shows interesting seasonal patterns. Spring emerges as the most productive season with an impressive 6.76 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 6.23 kWh/day, while autumn and winter show somewhat reduced but still substantial output at 5.54 kWh/day and 5.09 kWh/day respectively. This seasonal variation indicates that while solar energy generation remains viable year-round in Fagundes, Paraíba, planning for slightly lower output during the winter months would be prudent for those depending heavily on solar power. The difference between the best and worst seasons amounts to approximately 25%, which is relatively modest compared to locations at higher latitudes where seasonal variations can be much more dramatic.

Optimal Panel Installation

For fixed solar panel installations in Fagundes, Paraíba, the ideal tilt angle to maximize year-round energy production is 6 degrees facing North. This relatively flat orientation reflects the location's proximity to the equator, where the sun passes nearly overhead throughout much of the year. This optimal angle has been calculated by analyzing daily solar elevation patterns at this specific latitude, weighted according to the daily photovoltaic potential at this location.

Environmental and Weather Considerations

Several environmental factors could potentially affect solar production in Fagundes:

• Seasonal rainfall: The tropical location means Fagundes likely experiences a distinct wet season, during which cloud cover could temporarily reduce solar output. Installing slightly more capacity than minimally required can help compensate for these cloudy periods.
• Dust and pollen accumulation: Agricultural activities and the natural environment in the region may produce airborne particles that settle on panels, reducing efficiency. Regular cleaning schedules should be implemented, potentially more frequently during dry seasons when dust is more prevalent.
• High temperatures: Tropical locations can experience high ambient temperatures, which can slightly reduce solar panel efficiency. Ensuring adequate airflow beneath panels and selecting high-temperature-rated equipment can mitigate this effect.

To maximize production despite these challenges, installations should incorporate elevated mounting structures with good ventilation, automated or manual cleaning systems, and potentially tracking systems for larger installations to capture the maximum available sunlight throughout the day. Additionally, regular maintenance checks, particularly before and after the wet season, can help ensure optimal performance year-round.

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

Ideally tilt fixed solar panels 6° North in Fagundes, Brazil

To maximize your solar PV system's energy output in Fagundes, Brazil (Lat/Long -7.355, -35.775) 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 Fagundes, 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 Fagundes, 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
8° 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 Fagundes, 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 Fagundes, 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 Fagundes, Brazil

Topographical Features of Fagundes

Fagundes sits within the Agreste region of Paraíba state in northeastern Brazil, positioned on the transition zone between the coastal lowlands and the interior plateau known as the Planalto da Borborema. The landscape around this municipality is characterized by gently rolling hills and undulating terrain typical of the Brazilian Northeast's semi-arid interior. Elevations in the immediate area range from approximately 400 to 600 meters above sea level, creating a moderately elevated plateau environment. The region features predominantly crystalline rock formations from the Precambrian period, which have been weathered over millions of years to create the current topographical profile. Small valleys and depressions dot the landscape, often following ancient drainage patterns, while low ridges and gentle slopes dominate the overall terrain. The soil composition consists mainly of shallow, rocky soils with patches of deeper alluvial deposits in the valley floors. Vegetation in the area is primarily Caatinga, the thorny scrubland ecosystem adapted to semi-arid conditions. This sparse vegetation coverage means that much of the land surface receives direct exposure to sunlight throughout the year, with minimal shading from tree cover. The landscape is punctuated by seasonal streams and small reservoirs that collect water during the rainy season.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Fagundes would be the relatively flat to gently sloping areas found on the broader plateau surfaces. These areas offer several advantages including stable ground conditions, minimal grading requirements, and excellent solar exposure due to their elevation and sparse vegetation cover. The elevated plateau areas to the north and east of Fagundes present particularly favorable conditions, as they combine relatively level terrain with good accessibility via existing road networks. These locations would require minimal site preparation while providing the stable foundation necessary for large solar arrays. The crystalline bedrock underlying much of this terrain offers excellent structural support for mounting systems. Valley floors and lower-lying areas, while potentially offering flat surfaces, would be less ideal due to higher moisture retention, potential flooding during seasonal rains, and possible shading effects from surrounding elevated terrain. The gentle south-facing slopes found throughout the region could also prove suitable, as they would maximize solar collection efficiency while maintaining reasonable construction and maintenance access. Areas with existing infrastructure connections, particularly those near the BR-230 highway corridor that passes through the region, would be especially attractive for development due to reduced costs for grid connection and equipment transportation. The relatively sparse population density in the rural areas surrounding Fagundes means that large tracts of land could potentially be developed without significant residential displacement concerns.
