Pineville, Louisiana, situated in the northern subtropics at coordinates 31.2232, -92.3203, offers a reasonably good location for solar PV energy generation, though with notable seasonal variations. This central Louisiana city experiences strong solar production potential during summer months, with moderate to good production in spring and fall, but significantly reduced output during winter.
Solar panels in Pineville generate their highest electricity output during summer, producing approximately 6.55 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.36 kWh/day, while autumn yields a respectable 4.55 kWh/day. Winter performance drops considerably to 2.89 kWh/day, reflecting the shorter days and lower sun angles during this season.
For residents and businesses in Pineville considering solar installation, the optimal configuration for fixed panels is a 27-degree tilt facing south. This specific angle maximizes year-round energy production by optimizing exposure across all seasons, accounting for the location's subtropical latitude and seasonal sun paths.
Environmental and Weather Factors
Several environmental factors in Pineville may impact solar production. The region experiences high humidity and significant rainfall throughout the year, which can temporarily reduce solar efficiency during precipitation events. Additionally, Pineville's location places it at risk for occasional tropical storms and hurricanes that can damage installations if not properly secured.
The area also experiences approximately 15-20 days of fog annually, primarily during winter and early spring mornings, which can temporarily reduce morning production. Summer months bring high temperatures that can slightly reduce panel efficiency when modules exceed optimal operating temperatures.
Preventative Measures
To maximize solar production in Pineville despite these challenges, several preventative measures are recommended. Installing panels with sturdy mounting systems rated for high wind loads helps protect against tropical storm and hurricane damage. Selecting panels with anti-soiling properties assists with the humid conditions, while ensuring proper airflow beneath modules can mitigate heat-related efficiency losses during summer.
Regular cleaning schedules are particularly important in this humid environment to remove pollen, dust, and organic matter that accumulates more readily than in drier climates. Additionally, slightly increasing the panel tilt beyond the optimal 27 degrees can help with self-cleaning during the frequent rain events experienced in this region.
Despite these considerations, Pineville's location provides sufficient solar resources to make PV installations economically viable, particularly when systems are properly designed to account for the local environmental conditions.

Ideally tilt fixed solar panels 27° South in Pineville, United States
To maximize your solar PV system's energy output in Pineville, United States (Lat/Long 31.2232, -92.3203) 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 Pineville, 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 Pineville, 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 |
|---|---|---|---|
| 15° South in Summer | 36° South in Autumn | 47° South in Winter | 24° 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 Pineville, United States

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Pineville, United States
The landscape surrounding Pineville, Louisiana, is characterized by gentle, rolling terrain that forms part of the broader East Gulf Coastal Plain. This region features modest elevation changes, with the highest points typically rising no more than 150-200 feet above sea level. The topography has been shaped over millennia by the Red River, which flows near Pineville and has created a valley with fertile alluvial soils.
Natural Features
The immediate vicinity of Pineville includes a mix of forested areas, agricultural lands, and urban development. Pine forests dominate much of the undeveloped land, giving the city its name. These woodlands transition to mixed hardwood forests in lower-lying areas, particularly along the Red River and its tributaries. Small streams and bayous crisscross the landscape, creating minor valleys and drainage patterns throughout the region. To the west of Pineville, the terrain gradually flattens as it extends toward central Louisiana's prairie regions. The eastern side features slightly more pronounced hills and ravines, especially as one moves toward the Kisatchie National Forest, where the terrain becomes more varied with sandstone outcroppings and steeper slopes in some areas.Potential for Solar Development
For large-scale solar photovoltaic development, several areas near Pineville offer favorable conditions. The most suitable locations would be found on: The gently sloping agricultural lands northwest and southwest of Pineville present prime opportunities for solar development. These areas feature relatively flat terrain with minimal shading from natural features, providing excellent exposure for solar collection. The existing agricultural use typically means these lands are already cleared of significant forest cover. Former timber production areas that have been recently harvested could also be repurposed for solar installations. These sites are common in the region and often feature south-facing gentle slopes that maximize solar exposure throughout the day. The slightly elevated plateaus to the northeast of Pineville, extending toward Kisatchie National Forest, offer another possibility. While some selective clearing might be necessary, these areas benefit from higher elevation that reduces morning fog effects common in lower-lying areas.Topographical Considerations
When evaluating specific sites for solar development around Pineville, several topographical factors merit attention. South-facing slopes, even gentle ones, provide optimal sun exposure in this Northern Hemisphere location. The modest hills in the area can sometimes be advantageous, as they can reduce early morning fog impacts that occasionally affect the Red River valley floor. Drainage patterns are another important consideration. The region receives substantial annual rainfall, so ideal solar sites would feature natural gentle slopes that provide adequate drainage without experiencing erosion issues. Areas with existing erosion problems or those in flood-prone zones near the Red River and its tributaries should be avoided. The clay-rich soils common to parts of this region may require specific foundation designs for solar array installations, but generally don't present major obstacles to development. Overall, the topographical characteristics of the Pineville area are quite conducive to solar energy development, with numerous suitable locations within a short distance of the city.United States solar PV Stats as a country
