Solar Energy Potential in Bayeux, Paraíba, Brazil

Bayeux, Paraíba, Brazil, located at latitude -7.1197 and longitude -34.914, offers excellent conditions for solar energy production throughout the year. This tropical location benefits from consistent sunlight patterns with relatively minor seasonal variations compared to locations at higher latitudes. The solar energy generation potential in Bayeux demonstrates good year-round performance with some seasonal fluctuations. Spring yields the highest energy output at 7.19 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 6.95 kWh/day, while autumn produces 6.17 kWh/day. Winter shows the lowest output at 5.58 kWh/day, but this figure remains substantial compared to many other global locations.

Optimal Panel Installation

For fixed solar panel installations in Bayeux, Paraíba, the ideal tilt angle to maximize year-round energy production is 6 degrees facing North. This slight tilt optimizes energy capture across seasons, accounting for the sun's position throughout the year at this near-equatorial latitude.

Seasonal Considerations

The spring and summer months clearly represent peak production periods in Bayeux, Paraíba, making these ideal times for generating solar energy. However, the relatively small difference between the highest and lowest seasonal outputs (just 1.61 kWh/day) demonstrates the location's consistency for solar generation throughout the year.

Environmental and Weather Factors

Several environmental factors could potentially impact solar production in Bayeux:

• High humidity and coastal conditions may lead to salt corrosion on solar equipment
• The region's wet season can bring extended cloud cover, temporarily reducing generation
• Tropical vegetation growth may cause shading issues if not properly managed

To mitigate these challenges, several preventative measures are recommended. Installing corrosion-resistant mounting hardware and marine-grade components will protect against salt-air degradation. Regular panel cleaning, especially after the wet season, prevents dust and debris accumulation. Additionally, strategic vegetation management around installations prevents unexpected shading issues. Despite these considerations, Bayeux's location presents minimal serious impediments to solar energy production, making it an excellent candidate for solar PV installations with consistent year-round energy generation potential.

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 Bayeux

Seasonal solar PV output for Latitude: -7.1197, Longitude: -34.914 (Bayeux, 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 Bayeux, Brazil

To maximize your solar PV system's energy output in Bayeux, Brazil (Lat/Long -7.1197, -34.914) 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 Bayeux, 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 Bayeux, 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 Bayeux, 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 Bayeux, 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 Bayeux, Brazil

The region surrounding Bayeux in Brazil presents a varied and dynamic topography characteristic of the northeastern Brazilian coastline. Located in the state of Paraíba, Bayeux sits near the capital city of João Pessoa along the Atlantic Ocean. The terrain in this area is generally characterized by a coastal plain that gradually rises into rolling hills as one moves inland.

Near the coast, the landscape features extensive mangrove ecosystems along the Paraíba River estuary, with relatively flat, low-lying areas that have been heavily urbanized. These coastal plains have elevations typically ranging from sea level to about 40 meters. The soil composition in these areas tends to be sandy with areas of clay deposits, particularly around the river systems.

Inland Topography

Moving westward from Bayeux, the terrain begins to undulate more significantly. The landscape transitions into gently rolling hills with occasional plateaus, known locally as "tabuleiros." These plateaus typically range from 50 to 150 meters above sea level and feature relatively flat tops with steeper edges. The soil in these inland areas is generally more clay-rich and reddish in color, characteristic of the tropical soils found throughout much of northeastern Brazil.

The region experiences a tropical climate with distinct wet and dry seasons. This climate pattern has influenced the natural vegetation, which transitions from coastal mangroves to Atlantic Forest remnants and then to more drought-resistant caatinga vegetation as one moves further inland.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, the inland plateau regions west and southwest of Bayeux offer the most promising conditions. These "tabuleiros" provide several advantages for solar development:

The elevated plateaus receive consistent solar radiation throughout the year, with minimal shadowing from surrounding terrain. The flat topography of these plateaus minimizes the need for extensive land grading, reducing construction costs and environmental impact. These areas are also typically less densely populated than the coastal zones, providing more available land for large installations.

Specifically, the plateaus extending from the municipalities of Santa Rita and Conde (south of Bayeux) into the interior regions offer excellent potential. These areas combine favorable topography with proximity to existing transmission infrastructure, as they are not far from the metropolitan region of João Pessoa.

The drier climate of these inland areas also means less cloud cover during much of the year, particularly during the dry season from September to February. This climate pattern enhances the reliability of solar generation in these locations.

It's worth noting that while the coastal plains technically could support solar installations, these areas have higher land values due to urbanization and tourism development, making them less economically viable for large-scale solar projects. Additionally, the coastal zones experience more frequent cloud cover from maritime influences, which can reduce solar efficiency.

The transitional zones between the coastal plains and the inland plateaus, approximately 15-30 kilometers from the coast, represent a reasonable compromise between optimal solar conditions and proximity to existing infrastructure and population centers where electricity demand is highest.
