Solar Energy Potential in Barra de Santa Rosa, Brazil

Barra de Santa Rosa, located in northeastern Brazil, presents a favorable location for solar energy generation throughout the year. This tropical location benefits from consistent sunlight patterns, making it a promising site for photovoltaic (PV) installations. The seasonal solar energy production shows strong performance across all seasons, with some notable variations. Spring stands out as the most productive season, yielding approximately 7.29 kWh per day for each kilowatt of installed solar capacity. Summer follows with 6.59 kWh/day, while autumn and winter produce 6.14 kWh/day and 5.73 kWh/day respectively.

Optimal Panel Installation

For fixed solar panel installations in Barra de Santa Rosa, the ideal tilt angle to maximize year-round energy production is 6 degrees facing North. This slight tilt optimizes the capture of solar radiation throughout the year, accounting for the location's proximity to the equator and the sun's seasonal path variations.

Seasonal Considerations

The relatively small variation between seasons indicates consistent solar potential throughout the year. The peak production during spring months suggests this would be an ideal time for energy-intensive activities or for storing excess energy if battery systems are in place. Winter, while still productive, shows the lowest output but remains quite viable for solar generation with 5.73 kWh/day per installed kilowatt—a figure that would still be considered good in many non-tropical regions.

Environmental and Weather Factors

Several environmental factors could potentially impact solar production in Barra de Santa Rosa:

• Seasonal dust accumulation during dry periods can reduce panel efficiency by up to 15% if not regularly cleaned
• Brief but intense tropical rainfall events, particularly during the wet season, can temporarily reduce output
• High temperatures in summer months may slightly reduce panel efficiency, as most PV panels lose efficiency above 25°C

Preventative Measures

To maximize solar energy production in this location, several preventative measures are recommended:

• Implement a regular cleaning schedule, particularly during dry seasons when dust accumulation is highest
• Install panels with sufficient elevation to prevent flooding during heavy rains
• Consider panels with good heat tolerance ratings and ensure adequate airflow beneath panels to minimize temperature-related efficiency losses
• Use microinverters or power optimizers to minimize the impact of partial shading from occasional cloud cover

Overall, Barra de Santa Rosa presents excellent conditions for solar energy generation with relatively minor seasonal variations, making it suitable for year-round solar power production with proper system design and maintenance.

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 Barra De Santa Rosa

Seasonal solar PV output for Latitude: -6.7904, Longitude: -36.0018 (Barra De Santa Rosa, 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 Barra De Santa Rosa, Brazil

To maximize your solar PV system's energy output in Barra De Santa Rosa, Brazil (Lat/Long -6.7904, -36.0018) 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 Barra De Santa Rosa, 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 Barra De Santa Rosa, 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 Barra De Santa Rosa, 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 Barra De Santa Rosa, 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 Barra De Santa Rosa, Brazil

Topography of Barra de Santa Rosa Region

Barra de Santa Rosa is situated in the northeastern Brazilian state of Paraíba, within a region characterized by a diverse topographical landscape. The terrain around this municipality features a mixture of gently rolling hills, intermittent plateaus, and shallow valleys, with elevations generally ranging between 400 and 600 meters above sea level. This area lies within Brazil's semi-arid region known locally as the "Agreste," which forms a transition zone between the more humid coastal areas to the east and the drier Sertão to the west. The landscape exhibits typical Caatinga characteristics, with predominantly scrubland vegetation adapted to the region's seasonal rainfall patterns. The topography has been shaped over millennia by erosional processes, resulting in a terrain that alternates between exposed rock formations and soil-covered areas. Several seasonal waterways cut through the region, creating natural drainage patterns that become active during the rainy season but remain dry for extended periods.

Terrain Features and Solar PV Suitability

The terrain surrounding Barra de Santa Rosa presents several advantageous features for solar photovoltaic development. The moderate elevation provides good exposure to sunlight throughout the day, while the generally flat to gently sloping terrain reduces complications associated with installation and maintenance of solar arrays. The relatively sparse vegetation of the Caatinga biome minimizes natural shading concerns that might otherwise reduce solar efficiency. The western and southern outskirts of Barra de Santa Rosa offer particularly favorable conditions for large-scale solar PV installations. These areas feature more extensive flat plains with minimal slope variations, reducing the need for significant terrain modifications during construction. The soil composition in these zones typically consists of sandy to rocky substrates that provide stable foundations for mounting systems while facilitating proper drainage during occasional heavy rainfall events.

Optimal Areas for Large-Scale Solar Development

Several specific zones within a 30-kilometer radius of Barra de Santa Rosa stand out as especially suited for large-scale solar PV development. The southwestern corridor extending toward the municipality of Remígio features expansive plateaus with minimal terrain obstacles and good accessibility via existing road networks. These plateaus receive consistent solar exposure throughout the year and offer sufficient space for industrial-scale installations. The northwestern sector approaching Picuí presents another promising zone, characterized by gently undulating terrain with favorable south-facing aspects that maximize solar gain. The soil stability in this area provides good conditions for ground-mounted systems, while the relatively sparse population density minimizes potential land-use conflicts. The eastern plains extending toward Cacimba de Dentro constitute a third area of high potential, offering extensive flat terrain with minimal vegetation coverage. This area benefits from reduced cloud formation patterns compared to areas closer to the coast, resulting in more consistent solar radiation conditions. Each of these areas benefits from the region's characteristic climate patterns, with minimal seasonal variation in day length and solar angle. The predominantly clear atmospheric conditions of the Brazilian Northeast interior further enhance the suitability of these locations for solar energy capture and conversion.
