Arabi, Louisiana, located in the Northern Sub Tropics at 29.9544° N, 90.0054° W, offers a reasonably good location for solar PV installations throughout the year. The seasonal electricity generation varies significantly, with the strongest production occurring during the summer months.

Seasonal Solar Production

Solar panels in Arabi demonstrate notable seasonal variation in energy production. Summer delivers the highest output at 5.76 kWh per day for each kilowatt installed, closely followed by spring with 5.65 kWh/day. Production decreases in autumn to 4.70 kWh/day, while winter represents the lowest generation period with 3.48 kWh/day per installed kilowatt.

This pattern indicates that Arabi's solar potential peaks during the warmer months (March through August), making these months ideal for maximum solar energy generation. Even during winter, however, the location still provides meaningful solar production, unlike more northern locations that might experience drastically reduced winter output.

Optimal Panel Installation

For fixed solar panel installations in Arabi, the ideal tilt angle to maximize year-round energy production is 27 degrees facing South. This angle optimizes the annual solar capture by accounting for the sun's changing position throughout the seasons.

Environmental and Weather Considerations

Several significant environmental factors may impact solar production in Arabi:

• Hurricane exposure: Located near the Gulf Coast, Arabi faces substantial hurricane risk which can damage solar installations and reduce production.
• High humidity and frequent precipitation: The subtropical climate brings humidity that can accelerate weathering of components and reduce panel efficiency.
• Flooding potential: Being in the greater New Orleans area, flooding presents a risk to ground-level electrical components.

To mitigate these challenges, solar installations in Arabi should incorporate hurricane-rated mounting systems designed to withstand high winds. Elevating inverters and electrical equipment above potential flood levels is essential. Additionally, regular cleaning to remove humidity-related residue and selecting panels with anti-corrosion treatments will help maintain optimal performance in this subtropical environment.

Despite these challenges, Arabi's relatively strong year-round solar radiation, particularly in spring and summer, makes it a viable location for solar PV investment with proper installation considerations.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Seasonal solar PV output for Latitude: 29.9544, Longitude: -90.0054 (Arabi, United States), 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 27° South in Arabi, United States

To maximize your solar PV system's energy output in Arabi, United States (Lat/Long 29.9544, -90.0054) throughout the year, you should tilt your panels at an angle of 27° South 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 Arabi, United States

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 Arabi, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
14° South in Summer	35° South in Autumn	45° South in Winter	23° South 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 Arabi, United States

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 Arabi, United States.

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 Arabi, United States

The topography around Arabi, Louisiana presents a distinctively flat landscape characteristic of the Mississippi River Delta region. Located in St. Bernard Parish, just east of New Orleans, Arabi sits at an extremely low elevation, typically only a few feet above sea level. This area is part of the vast alluvial plain formed by centuries of sediment deposition from the Mississippi River. The terrain is remarkably level with minimal natural elevation changes across the landscape.

Wetland Influence

The surrounding environment consists largely of wetlands, marshes, and swamps that extend eastward toward Lake Borgne and the Gulf of Mexico. These low-lying areas are interspersed with numerous waterways, including canals, bayous, and distributaries of the Mississippi River. The soil composition is predominantly alluvial, consisting of silt and clay deposits that have accumulated over thousands of years of river flooding cycles.

Flood Vulnerability

This flat topography makes Arabi and the surrounding areas particularly vulnerable to flooding. Much of the region lies below sea level and depends on an extensive system of levees, pumps, and flood control structures for protection. Following Hurricane Katrina in 2005, significant improvements were made to the flood protection infrastructure, though the fundamental topographical challenges remain.

Solar PV Potential Areas

For large-scale solar photovoltaic (PV) development, several factors must be considered beyond the immediate flatness of the terrain. While flat land is typically advantageous for solar installations, the flood-prone nature of this region presents significant challenges. Areas most suitable for large-scale solar PV near Arabi would include: The slightly elevated portions of St. Bernard Parish that sit on natural levees, particularly along major roadways like Judge Perez Drive, where the land has been built up and reinforced. These areas offer better drainage and reduced flood risk compared to surrounding lowlands. Reclaimed industrial zones in neighboring Chalmette and Meraux might offer suitable locations, as these areas often feature improved drainage systems and elevated foundations. Former industrial sites that have been properly remediated could provide ideal spaces for solar development without displacing residential or agricultural uses. The eastern portions of St. Bernard Parish, moving toward Violet and Poydras, contain some agricultural land on slightly higher ground that could potentially accommodate solar installations, though careful flood mitigation strategies would still be essential.

Topographical Challenges

Any solar development in this region must contend with several topography-related challenges. The high water table limits the depth of foundations and underground infrastructure. Seasonal tropical storms and hurricanes present risks of wind damage and flooding. Additionally, the soft alluvial soils may require specialized mounting systems and foundations to ensure the stability of solar arrays. Despite these challenges, the fundamental flatness of the terrain does eliminate concerns about shading from hills or mountains, which is a significant advantage for solar energy production. With proper engineering and site selection focused on the slightly higher elevation areas, large-scale solar PV development remains feasible in the vicinity of Arabi.
