Elkins, Arkansas, located in the Northern Temperate Zone, offers a moderate potential for solar energy generation throughout the year. The location's solar production capabilities vary significantly across seasons, presenting both opportunities and challenges for solar PV installations.

Seasonal Solar Production

Solar energy output at this location fluctuates considerably with the changing seasons. Summer stands out as the most productive period, with an impressive 6.95 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.19 kWh/day/kW. Autumn sees a noticeable decrease in production at 4.41 kWh/day/kW, while winter experiences the lowest output at 2.66 kWh/day/kW.

These figures indicate that solar energy generation in Elkins is most effective from late spring through early fall. During these months, longer days and higher sun angles contribute to increased solar panel efficiency and output.

Optimal Panel Installation

To maximize year-round solar energy production in Elkins, fixed solar panels should be installed at a tilt angle of 31 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental Considerations

While Elkins generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

1. Tree cover: The area's vegetation might cast shadows on solar panels, reducing their efficiency. Regular trimming of nearby trees can help maintain optimal sun exposure.
2. Weather patterns: Occasional severe weather events, such as thunderstorms or hail, could potentially damage solar installations. Using durable, weather-resistant panels and protective coverings can mitigate these risks.

To enhance solar production in Elkins, consider implementing a tracking system that adjusts panel angles throughout the day. This can significantly increase energy output, especially during the less productive winter months. Additionally, regular cleaning and maintenance of the panels will help ensure they operate at peak efficiency year-round.

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 Elkins

Seasonal solar PV output for Latitude: 36.0015, Longitude: -94.0083 (Elkins, 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 Elkins, United States

To maximize your solar PV system's energy output in Elkins, United States (Lat/Long 36.0015, -94.0083) 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 Elkins, 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 Elkins, 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	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 Elkins, 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 Elkins, 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 Elkins, United States

The area around Elkins, Arkansas, located at 36.0015 degrees north latitude and 94.0083 degrees west longitude, is characterized by a diverse and picturesque topography typical of the Ozark Mountains region. This part of northwest Arkansas features a mix of rolling hills, forested areas, and small valleys, creating a scenic landscape that is both beautiful and challenging. The terrain surrounding Elkins is generally hilly, with elevations ranging from about 1,000 to 1,500 feet above sea level. The land is not uniformly mountainous but rather consists of a series of ridges and valleys, often referred to as the Boston Mountains, which form the southern part of the Ozark Plateau. These hills are covered with dense deciduous forests, primarily oak and hickory trees, interspersed with open areas used for agriculture and pasture.

Waterways and Valleys

Several streams and small rivers cut through the landscape, forming narrow valleys between the hills. The White River, a major waterway in the region, flows not far from Elkins, contributing to the area's drainage system and adding to its natural beauty. These waterways have, over time, carved out scenic valleys and created fertile bottomlands that contrast with the surrounding uplands.

Potential for Solar PV Installation

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The hilly terrain presents both challenges and opportunities for solar energy development. Ideally, solar farms require relatively flat land with good sun exposure throughout the day. Some of the more suitable areas for solar PV installations near Elkins might include: 1. Open agricultural fields or pastures on the tops of broader hills or ridges, where the land is flatter and there is less shading from surrounding trees or terrain. 2. Valley floors that are wide enough to accommodate large arrays and are oriented in a way that maximizes sun exposure, particularly those running east-west. 3. Areas that have been previously cleared for other purposes, such as former industrial sites or large rural properties with expansive open spaces. It's important to note that while the region does have potential for solar energy development, the overall topography may limit the size and number of suitable sites for large-scale installations compared to flatter regions. Any solar project in this area would need careful planning to work with the existing landscape and minimize environmental impact on the region's natural beauty and ecosystems.
