Houma, Louisiana offers reasonably good conditions for solar energy generation throughout most of the year, though it experiences significant seasonal variation typical of its Northern Sub-tropical location.

Seasonal Solar Performance

The solar energy output at this location shows strong performance during warmer months and reduced efficiency in winter. Summer delivers the highest energy production at 5.76 kWh per day per kW of installed solar capacity, while spring follows closely at 5.66 kWh per day. Autumn provides moderate output at 4.70 kWh per day, but winter sees a notable drop to 3.47 kWh per day. This seasonal pattern means that approximately 60% of annual solar energy production occurs during the six-month period from March through August. The location performs particularly well during late spring through early fall, making it most effective for offsetting air conditioning costs during Louisiana's hot, humid summers.

Optimal Panel Configuration

For fixed panel installations at Houma, the ideal tilt angle is 27 degrees facing south to maximize total year-round energy production. This angle balances the sun's varying position throughout the seasons to capture the most solar energy over the entire year.

Environmental and Weather Challenges

Several local factors can significantly impact solar energy production in the Houma area and require careful consideration during installation:

• Hurricane and severe storm risks - The Gulf Coast location makes this area vulnerable to hurricanes and intense thunderstorms with high winds
• High humidity and frequent rainfall - Louisiana's subtropical climate brings heavy moisture that can affect equipment longevity
• Salt air exposure - Proximity to coastal areas introduces salt-laden air that can corrode solar equipment
• Frequent cloud cover and thunderstorms - Afternoon and evening storms are common, particularly in summer months

Preventative Installation Measures

To maximize energy production and system longevity despite these challenges, several installation strategies prove essential: Hurricane-rated mounting systems designed to withstand winds exceeding 150 mph should be standard, with panels secured using reinforced rails and additional fastening points. Proper drainage design prevents water accumulation around electrical components and mounting hardware. Selecting solar panels and inverters with enhanced corrosion resistance helps combat salt air exposure. Marine-grade wiring, sealed electrical connections, and regular cleaning schedules remove salt buildup that can reduce panel efficiency. Installing micro-inverters or power optimizers rather than string inverters helps maintain energy production when individual panels are shaded by passing clouds or storm systems. This technology prevents the performance of one affected panel from reducing the output of the entire array. Regular maintenance including professional cleaning and inspection becomes particularly important in this environment. Scheduling maintenance before and after hurricane season ensures systems remain secure and efficient year-round.

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

Solar output per kW of installed solar PV by season in Houma

Seasonal solar PV output for Latitude: 29.6289, Longitude: -90.7262 (Houma, 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 Houma, United States

To maximize your solar PV system's energy output in Houma, United States (Lat/Long 29.6289, -90.7262) 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 Houma, 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 Houma, 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 Houma, 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 Houma, 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 Houma, United States

Topographical Features Around Houma

The landscape surrounding Houma, Louisiana is characterized by extremely flat, low-lying terrain that sits barely above sea level. This region forms part of the Mississippi River Delta, where centuries of sediment deposition have created a remarkably level topography with minimal elevation changes across vast distances. The area consists primarily of coastal marshlands, wetlands, and bayous that extend in all directions from the city center. The terrain is dominated by soft, alluvial soils composed of fine sediments carried down by the Mississippi River system over thousands of years. These soils are typically saturated with water, creating a landscape punctuated by numerous waterways, including bayous, canals, and small lakes. The natural drainage patterns flow generally southward toward the Gulf of Mexico, which lies approximately 40 miles to the south. Elevation changes throughout the region are so subtle that they are often measured in mere feet rather than the typical hills or valleys found in other parts of the country. The highest ground tends to be along natural levees near waterways or on small ridges that have formed through sediment accumulation. Much of the surrounding area consists of freshwater and saltwater marshes that flood regularly with tidal changes and seasonal weather patterns.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Houma would be found on the slightly elevated ridge areas and natural levees that provide better drainage and more stable foundation conditions. These areas typically run parallel to major waterways like Bayou Terrebonne and the Intracoastal Waterway, where sediment deposits have created marginally higher ground over time. Agricultural areas northwest and west of Houma present some of the best opportunities for solar development, as these lands have been cleared, leveled, and often feature improved drainage systems. The sugarcane fields and pastures in Terrebonne and Lafourche parishes offer large, relatively flat parcels that could accommodate substantial solar arrays while avoiding the most sensitive wetland areas. Industrial corridors along major transportation routes, particularly near Highway 90 and the areas around existing oil and gas infrastructure, provide additional suitable locations. These zones often feature compacted soils, existing electrical infrastructure, and road access that would support large-scale solar installations. The proximity to industrial facilities also means potential customers for the generated electricity are nearby. Areas closer to the Gulf Coast become increasingly challenging for solar development due to higher salinity, more frequent flooding, and greater exposure to tropical weather systems. The northern portions of the region, while still quite flat, generally offer better drainage and more stable soil conditions that would be preferable for mounting large solar installations.
