Van Buren, Arkansas, United States offers a moderately favorable location for year-round solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.
Seasonal Solar Performance
The solar energy output at this location shows distinct seasonal patterns. Summer delivers the strongest performance at 6.86 kWh per day per kW of installed capacity, making it the prime season for solar generation. Spring follows as the second-best period with 5.22 kWh per day per kW, offering excellent conditions for solar production. Autumn sees a notable decline to 4.49 kWh per day per kW, while winter presents the most challenging conditions with only 2.64 kWh per day per kW. This represents a dramatic difference between peak summer and winter production, with summer generating nearly three times more energy than winter months.Optimal Installation Configuration
For maximum year-round energy production at Van Buren, solar panels should be installed at a fixed tilt angle of 31 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and weighting the angles based on actual solar irradiance data.Local Environmental and Weather Factors
Several regional factors in Van Buren could potentially impact solar energy production:- Severe Weather Events: Arkansas experiences thunderstorms, hail, and occasional tornadoes that can damage solar installations
- High Humidity and Heat: Summer conditions can reduce panel efficiency and accelerate equipment degradation
- Tree Coverage: The region's dense vegetation can create shading issues, particularly during lower sun angle seasons
- Dust and Pollen: Seasonal pollen and agricultural dust can accumulate on panels, reducing light transmission
Preventative Measures for Enhanced Performance
To maximize solar energy production despite these challenges, several preventative measures should be implemented:- Impact-Resistant Panels: Install panels rated for hail impact and high wind loads to withstand severe weather
- Proper Ventilation: Ensure adequate airflow beneath panels to manage heat buildup and maintain efficiency
- Strategic Placement: Conduct thorough shade analysis and trim vegetation regularly to minimize shading throughout the day
- Regular Cleaning Schedule: Implement routine panel cleaning, especially during high pollen seasons in spring
- Quality Mounting Systems: Use robust mounting hardware designed for the region's weather patterns
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Van Buren
Seasonal solar PV output for Latitude: 35.4563, Longitude: -94.3298 (Van Buren, 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 31° South in Van Buren, United States
To maximize your solar PV system's energy output in Van Buren, United States (Lat/Long 35.4563, -94.3298) throughout the year, you should tilt your panels at an angle of 31° 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 Van Buren, 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 Van Buren, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 19° South in Summer | 40° South in Autumn | 51° South in Winter | 29° 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 Van Buren, 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 Van Buren, 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 Van Buren, United States
Topographical Features Around Van Buren
Van Buren sits in the Arkansas River Valley of west-central Arkansas, positioned along the northern bank of the Arkansas River. The terrain in this region is characterized by relatively gentle topography, with the city itself located at a modest elevation on river terraces that provide natural drainage. The Arkansas River forms a significant geographical feature, flowing westward through the valley and creating fertile bottomlands on both sides. To the north of Van Buren, the landscape gradually rises toward the foothills of the Ozark Mountains. These hills create a series of rolling ridges and valleys, with elevations increasing as one moves further north. The terrain becomes more dissected and steep in these areas, with numerous small creeks and tributaries cutting through the landscape as they flow toward the Arkansas River. South of the city, across the Arkansas River, the land transitions into the Arkansas River Valley's southern reaches. This area features a mix of river terraces, bottomlands, and gentle slopes that extend toward the Ouachita Mountains further south. The topography here is generally less rugged than the northern areas, with broader valleys and more gradual elevation changes.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Van Buren would be the relatively flat to gently sloping areas south and southwest of the city. These locations offer several advantages, including minimal grading requirements, reduced installation costs, and fewer topographical obstacles that could create shading issues. The river terraces and broader valley floors in these areas provide extensive tracts of land with consistent solar exposure throughout the day. Areas to the immediate east and west of Van Buren also present favorable conditions for solar development. The Arkansas River Valley extends in both directions, creating corridors of relatively level terrain that would accommodate large solar arrays. These locations benefit from the valley's natural orientation and the absence of significant topographical barriers that might interfere with solar collection. The agricultural lands surrounding Van Buren, particularly those on the valley floor and lower terraces, represent prime candidates for solar development. These areas typically feature gentle slopes that can be easily adapted for solar panel installation while maintaining good drainage characteristics. The existing cleared land reduces preparation costs and environmental impact compared to forested or more topographically challenging sites. Areas to avoid for large-scale solar installations include the steeper terrain to the north, where the Ozark foothills create irregular topography with significant elevation changes. These locations would require extensive grading and could face shading issues from adjacent ridges and hills. Similarly, the more dissected terrain along creek valleys and drainage areas would present challenges for large-scale installations due to irregular slopes and potential flooding concerns.United States solar PV Stats as a country
