Huntingdon, Tennessee shows moderate potential for year-round solar energy generation, though with significant seasonal variations that homeowners and businesses should consider when planning solar installations.

Seasonal Solar Performance

The solar energy output at this Northern Temperate Zone location varies considerably throughout the year. Summer provides the strongest performance at 6.51 kWh per day per installed kilowatt, making it the peak season for solar generation. Spring follows as the second-best season with 5.63 kWh daily output per kilowatt, offering excellent production during the longer days of March through May. Autumn sees a notable decline to 4.14 kWh per day per kilowatt as daylight hours shorten and the sun's angle decreases. Winter presents the most challenging conditions, dropping to just 2.49 kWh daily per kilowatt - less than half of summer's peak output.

Optimal Installation Setup

For maximum year-round energy production at this location, solar panels should be installed at a fixed tilt angle of 31 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's seasonal path and daily solar irradiance patterns specific to Huntingdon's latitude.

Local Environmental Challenges

Several regional factors in Tennessee can impact solar panel efficiency and require preventative measures during installation:

• High humidity and frequent storms: Tennessee's humid subtropical climate can lead to moisture buildup and severe weather events including hail, high winds, and tornadoes
• Tree coverage: The region's abundant forests and mature trees can create shading issues throughout the day
• Dust and pollen: Heavy pollen seasons and agricultural dust can accumulate on panel surfaces
• Ice and snow: Winter weather can occasionally bring ice storms and snow accumulation

Preventative Installation Measures

To maximize solar production despite these challenges, several installation strategies should be implemented. Proper mounting systems rated for high wind loads and impact-resistant panels can withstand severe weather events. Adequate spacing between panels allows for air circulation, reducing moisture-related issues. Careful site selection and tree trimming help minimize shading throughout the year, while installing panels with anti-reflective coatings and smooth surfaces makes cleaning easier and reduces dust accumulation. Steeper mounting angles naturally help shed snow and debris, though this must be balanced with the optimal 31-degree angle for maximum annual production. Regular maintenance schedules for cleaning and inspection become particularly important in this climate to ensure panels continue operating at peak efficiency despite environmental challenges.

Solar output per kW of installed solar PV by season in Huntingdon, Tennessee

Seasonal solar PV output for Latitude: 36.006, Longitude: -88.4252 (Huntingdon, Tennessee, 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 Huntingdon, Tennessee, United States

To maximize your solar PV system's energy output in Huntingdon, Tennessee, United States (Lat/Long 36.006, -88.4252) 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 Huntingdon, Tennessee, 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 Huntingdon, Tennessee, 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 Huntingdon, Tennessee, 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 Huntingdon, Tennessee, 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 Huntingdon, Tennessee, United States

Topographical Features Around Huntingdon

The area surrounding Huntingdon in Carroll County, Tennessee is characterized by gently rolling hills and relatively modest elevation changes typical of the western Tennessee landscape. This region sits within the broader Tennessee River valley system, where the topography has been shaped by centuries of river activity and erosion. The terrain generally slopes toward the Tennessee River, which flows roughly fifteen miles to the north of Huntingdon. The elevation around Huntingdon ranges from approximately 400 to 600 feet above sea level, with the town itself positioned at around 450 feet. The landscape features a series of low ridges and shallow valleys that run in a generally northeast-southwest direction, following the natural drainage patterns of the area. These ridges are typically separated by small creeks and tributaries that eventually flow into larger waterways. The soil composition in this region consists primarily of clay and loam mixtures, with some areas containing sandy deposits left behind by ancient river systems. The terrain is generally stable, though the clay-heavy soils can present drainage challenges during periods of heavy rainfall. Most of the area has been cleared for agricultural use over the past century, leaving relatively few forested areas compared to the original landscape.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Huntingdon would be the elevated ridge areas and gentle south-facing slopes that characterize much of the surrounding countryside. These elevated positions offer several advantages, including reduced risk of flooding, better drainage, and fewer obstructions from trees or buildings that might create shading issues. The agricultural fields that dominate the landscape south and southwest of Huntingdon present particularly promising opportunities for solar development. These areas have already been cleared and leveled for farming operations, which significantly reduces the site preparation costs associated with solar installations. The relatively flat to gently sloping terrain in these agricultural zones would allow for efficient placement of solar arrays with minimal grading requirements. Areas along the higher ridgelines, particularly those running parallel to Highway 70 and extending toward the communities of McLemoresville and Clarksburg, offer excellent potential due to their elevation and exposure. These locations benefit from being above the immediate drainage areas while still maintaining reasonable access to existing electrical infrastructure and transportation networks. The terrain immediately north of Huntingdon, while closer to the Tennessee River valley, tends to be lower in elevation and more prone to seasonal flooding concerns. These areas would generally be less suitable for large-scale solar development due to potential water management issues and the increased costs associated with flood-resistant installations. Eastern areas around Huntingdon also present good opportunities, particularly where the landscape opens into broader agricultural valleys. These locations combine favorable topographical conditions with existing cleared land and reasonable proximity to electrical transmission infrastructure that could support utility-scale solar operations.
