Youngsville, Louisiana is a moderately good location for year-round solar energy generation, though it experiences significant seasonal variation in solar output. Located in the Northern Sub Tropics, this area produces decent solar energy throughout the year, with some seasons being much more productive than others.
Seasonal Solar Performance
Summer is by far the best season for solar production in Youngsville, generating 6.26 kWh per day for each kilowatt of installed solar capacity. This represents peak performance when the sun is highest in the sky and days are longest. Spring comes in second with 5.44 kWh per day per kilowatt, making it another excellent time for solar energy generation. Autumn sees a notable drop to 4.64 kWh per day per kilowatt, while winter represents the lowest production period at just 3.13 kWh per day per kilowatt. This winter figure is exactly half of the summer output, showing the substantial seasonal difference in solar potential. For optimal year-round energy production, solar panels should be installed at a fixed tilt angle of 27 degrees facing south. This angle maximizes the total annual solar output by balancing the sun's varying position throughout the seasons.Local Factors That May Impact Solar Production
Several environmental and weather factors in Youngsville could potentially reduce solar energy output:- High humidity levels typical of Louisiana can create hazy atmospheric conditions that reduce solar irradiance
- Frequent thunderstorms and heavy rainfall, particularly during summer months, can temporarily block sunlight
- Hurricane season brings extended periods of cloudy skies and severe weather that can damage equipment
- Spanish moss and other vegetation common to the region can grow on or near panels if not properly maintained
Recommended Preventative Measures
To maximize solar production despite these challenges, several installation strategies can help: Installing panels with adequate spacing allows for proper air circulation, which helps combat the effects of high humidity and keeps panels cooler for better efficiency. Choosing high-quality mounting systems rated for hurricane-force winds ensures panels can withstand severe weather events common to the Gulf Coast region. Regular cleaning schedules become especially important in Louisiana's humid climate to remove accumulated moisture, dirt, and organic matter that can reduce panel efficiency. Installing panels away from large trees or regularly trimming nearby vegetation prevents shading from Spanish moss and overhanging branches. Consider installing micro-inverters or power optimizers rather than string inverters, as these can minimize the impact when individual panels are temporarily shaded by passing clouds or weather systems. This technology ensures that shading on one panel doesn't significantly reduce the output of the entire solar array.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 Youngsville, Louisiana
Seasonal solar PV output for Latitude: 30.0997, Longitude: -91.9901 (Youngsville, Louisiana, 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 Youngsville, Louisiana, United States
To maximize your solar PV system's energy output in Youngsville, Louisiana, United States (Lat/Long 30.0997, -91.9901) 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 Youngsville, Louisiana, 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 Youngsville, Louisiana, 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 | 46° 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.

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 Youngsville, Louisiana, United States
Topographical Features of Youngsville
Youngsville sits in the heart of Louisiana's Acadiana region, positioned on relatively flat terrain characteristic of the Gulf Coastal Plain. The landscape around this area consists primarily of low-lying prairie land with gentle undulations that rarely exceed a few feet in elevation change. The terrain slopes very gradually southward toward the Gulf of Mexico, creating a predominantly level topography that extends for miles in all directions. The region features numerous waterways including bayous, coulees, and drainage canals that meander through the landscape. These water features create slight depressions and raised areas along their banks, but the overall elevation changes remain minimal. The Vermilion River system influences much of the local topography, with its tributaries creating subtle valleys and ridges throughout the surrounding countryside. Much of the land consists of former prairie that has been converted to agricultural use, particularly rice farming and cattle pastures. These agricultural areas maintain the naturally flat characteristics of the original landscape, with field boundaries often marked by tree lines or drainage ditches rather than significant elevation changes.Soil Composition and Drainage Patterns
The underlying geology consists primarily of alluvial deposits and marine sediments, creating soils that range from clay to sandy loam. These soils generally provide stable foundations, though drainage considerations become important due to the flat terrain and periodic heavy rainfall typical of the region. Many areas feature constructed drainage systems to manage water flow during wet periods. The natural drainage patterns flow generally southward and eastward toward larger waterways, but the minimal elevation changes mean that water movement is often slow. This characteristic has led to the development of extensive artificial drainage networks throughout the agricultural areas surrounding Youngsville.Optimal Areas for Large-Scale Solar Development
The flat topography around Youngsville presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas lie to the north and west of the town, where extensive agricultural fields provide large, unobstructed parcels of land with minimal grading requirements. These areas benefit from consistent terrain that would require little site preparation beyond standard agricultural field modifications. Agricultural lands currently used for rice cultivation present particularly attractive opportunities, as these fields are already leveled and have established access roads and drainage infrastructure. The existing field boundaries often encompass areas of several hundred acres, providing sufficient space for utility-scale solar farms without the need for extensive land assembly. Areas along the major transportation corridors, particularly near Interstate 49 and Highway 90, offer additional advantages for solar development due to existing electrical transmission infrastructure and improved access for construction and maintenance activities. The flat terrain in these corridors eliminates concerns about shading from topographical features and allows for optimal panel orientation. The western portions of Lafayette Parish, extending into the prairie lands beyond Youngsville, contain some of the most consistently flat and open terrain in the region. These areas feature minimal tree cover, few structures, and large contiguous parcels that would be well-suited to major solar installations. The existing agricultural infrastructure in these areas, including farm roads and utility connections, would facilitate solar development. Areas to avoid for large-scale solar development include the immediate floodplains of major waterways, where periodic flooding could pose operational challenges. Additionally, the more densely wooded areas along bayous and coulees would require extensive clearing and might face environmental restrictions that could complicate development.United States solar PV Stats as a country
