Goodlettsville, Tennessee, located in the Northern Temperate Zone, offers a moderately favorable environment for solar PV energy generation throughout the year. The location's potential for solar energy production varies significantly across seasons, with peak performance during the summer months.

Seasonal Solar Performance

Solar panels in Goodlettsville can be expected to generate the most electricity during summer, with an average daily output of 6.44 kWh per kW of installed capacity. Spring follows closely behind with 5.64 kWh/day. Autumn sees a noticeable decrease in production at 4.06 kWh/day, while winter experiences the lowest output at 2.51 kWh/day per kW installed.

The substantial variation between seasons suggests that Goodlettsville's solar potential is heavily influenced by the changing solar angles and daylight hours throughout the year. The location benefits from long, sunny days during summer and spring, making these seasons ideal for solar energy generation.

Optimal Panel Installation

For fixed panel installations in Goodlettsville, the ideal tilt angle to maximize year-round solar production is 31 degrees facing South. This angle optimizes the panels' exposure to sunlight across all seasons, balancing the high summer sun with the lower winter sun angle.

Environmental and Weather Considerations

While Goodlettsville's climate is generally conducive to solar energy production, there are some factors that could potentially impact solar panel efficiency:

• Occasional severe thunderstorms and tornadoes, which may cause physical damage to panels
• Humidity and precipitation, which could lead to temporary reductions in solar irradiance

To mitigate these risks, solar installations should incorporate sturdy mounting systems capable of withstanding high winds. Regular cleaning and maintenance can help combat the effects of humidity and precipitation on panel efficiency. Additionally, using high-quality, weather-resistant panels can ensure better performance in varying weather conditions.

Overall, while Goodlettsville experiences seasonal fluctuations in solar potential, its location in the Northern Temperate Zone provides a reasonably good environment for solar PV energy generation, especially during the spring and summer months.

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 Goodlettsville

Seasonal solar PV output for Latitude: 36.3403, Longitude: -86.7195 (Goodlettsville, 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 Goodlettsville, United States

To maximize your solar PV system's energy output in Goodlettsville, United States (Lat/Long 36.3403, -86.7195) 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 Goodlettsville, 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 Goodlettsville, 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	52° 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 Goodlettsville, 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 Goodlettsville, 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 Goodlettsville, United States

The area surrounding Goodlettsville, Tennessee, located at 36.3403°N, 86.7195°W, is characterized by gently rolling hills and shallow valleys typical of the Nashville Basin region. This topography is a result of the area's underlying limestone bedrock, which has been slowly eroded over millions of years, creating a landscape of low, rounded hills interspersed with fertile valleys and small streams. The terrain in and around Goodlettsville is generally mild, with elevations ranging from about 400 to 700 feet above sea level. The land gradually rises as you move east towards the foothills of the Appalachian Mountains, while to the west, it becomes slightly flatter as it approaches the Highland Rim. The nearby Cumberland River and its tributaries have carved out some steeper slopes and bluffs in certain areas, adding variety to the otherwise gentle landscape.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The gently rolling terrain of the region offers some advantages for solar development, as it provides natural drainage and reduces the risk of flooding. However, the ideal locations for solar farms would be areas with the following characteristics: Flat or gently sloping land: While the entire region is relatively mild in terms of topography, the flatter areas to the west and northwest of Goodlettsville would be more suitable for large solar installations. These areas require less grading and site preparation, reducing construction costs and environmental impact. Open fields: Agricultural land or former pastures that are no longer in active use would be ideal candidates for solar development. These areas are often already cleared of trees and have good sun exposure. Proximity to existing infrastructure: Sites close to major roads and electrical transmission lines would be preferable, as they reduce the costs associated with connecting the solar farm to the grid and transporting materials during construction. Areas with minimal shading: While the rolling hills can provide some natural beauty, they can also cast shadows that reduce solar efficiency. Therefore, open areas with unobstructed southern exposure would be most suitable for maximizing solar energy production. Land away from sensitive ecosystems: To minimize environmental impact, areas that are not home to threatened or endangered species, and that are not part of critical wildlife corridors, would be more appropriate for large-scale solar development. Given these considerations, the areas to the west and northwest of Goodlettsville, particularly those closer to the flatter regions of the Highland Rim, would likely be the most suitable for large-scale solar PV installations. However, specific site assessments would be necessary to determine the most optimal locations, taking into account local zoning regulations, land availability, and environmental factors.
