Yellville, Arkansas is a moderately good location for solar energy generation, though it experiences significant seasonal variation typical of the Northern Temperate Zone climate.

Seasonal Solar Performance

The solar energy output at this location varies considerably throughout the year. Summer provides the best conditions with 6.82 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows as the second-best season at 5.33 kWh per day, while autumn drops to 4.36 kWh per day. Winter presents the most challenging conditions with only 2.55 kWh per day, representing less than half of summer's output. For optimal year-round energy production from a fixed panel installation at this location, solar panels should be tilted at 31 degrees facing south. This angle maximizes the total annual solar output by accounting for the sun's changing position throughout the seasons.

Local Factors Affecting Solar Production

Several environmental and weather factors in the Yellville area can impact solar energy generation:

• Ice storms and heavy snow accumulation during winter months can block solar panels
• Severe thunderstorms with hail pose risks to panel integrity
• High humidity and frequent cloud cover can reduce solar irradiance
• Tornado activity in the region creates potential for wind damage
• Dense tree coverage common in Arkansas can create shading issues

Preventative Installation Measures

To maximize solar production despite these challenges, several installation strategies should be considered. Panels should be mounted with adequate clearance from the roof to allow snow and ice to slide off naturally. Installing panels at the recommended 31-degree tilt also helps with natural snow shedding. Choosing impact-resistant panels rated for hail damage is essential in this storm-prone region. Proper grounding and surge protection equipment will help protect the system from lightning damage during thunderstorms. Careful site selection is crucial - panels should be positioned away from large trees and in areas with maximum southern exposure. Regular tree trimming may be necessary to prevent shading as vegetation grows. Additionally, installing monitoring systems can help quickly identify when panels need cleaning or maintenance after severe weather events.

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 Yellville

Seasonal solar PV output for Latitude: 36.2262, Longitude: -92.6849 (Yellville, 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 Yellville, United States

To maximize your solar PV system's energy output in Yellville, United States (Lat/Long 36.2262, -92.6849) 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 Yellville, 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 Yellville, 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
20° South in Summer	41° 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 Yellville, 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 Yellville, 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 Yellville, United States

Topographical Features Around Yellville

Yellville sits in the heart of the Arkansas Ozarks, where rolling hills and deeply carved valleys define the landscape. The terrain around this small Marion County town is characterized by moderate elevation changes, with the area positioned at approximately 550 feet above sea level. The topography reflects the classic Ozark Mountain geography, featuring limestone bluffs, wooded ridges, and numerous stream valleys that cut through the countryside.

The Buffalo National River flows nearby, creating a significant valley system that has shaped much of the local topography. This river corridor and its tributaries have carved relatively steep-sided valleys through the underlying bedrock, creating a landscape of alternating ridges and hollows. The surrounding hills typically rise 200 to 400 feet above the valley floors, though some prominent ridges reach higher elevations.

Forest cover dominates much of the region, with oak-hickory woodlands blanketing the hillsides and ridgetops. Open agricultural areas tend to concentrate in the broader valley bottoms and on some of the more gently sloping hillsides. The soil composition varies considerably, with rocky, thin soils common on the steeper slopes and ridgetops, while deeper, more fertile soils are found in the valley bottoms.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Yellville would be the relatively flat to gently sloping agricultural areas found in the broader valley systems. These locations offer several advantages over the steeper, forested terrain that characterizes much of the region. The cleared farmland provides immediate access without requiring extensive tree removal, and the gentler slopes minimize the need for complex mounting systems or extensive grading.

South-facing slopes with gradients of less than 15 degrees present particularly attractive opportunities for solar development. These areas combine optimal orientation for solar collection with manageable terrain for construction and maintenance access. Several such locations exist along the broader creek valleys that feed into the Buffalo River system, where agricultural use has already cleared the land.

The ridgetops, while offering potential advantages in terms of reduced shading from surrounding terrain, present significant challenges due to their typically rocky soils, forest cover, and often irregular topography. Additionally, many of these elevated areas would require substantial infrastructure development to provide adequate road access for construction and ongoing maintenance operations.

Areas near existing infrastructure corridors, particularly along major county roads and near electrical transmission lines, would be most practical for development. The terrain immediately surrounding Yellville itself, where the landscape transitions from the steeper valley walls to more moderate slopes, offers some of the best combinations of suitable topography and infrastructure access. These locations typically feature partially cleared land with manageable slopes and proximity to existing electrical grid connections.
