Dyersburg, Tennessee, located in the Northern Temperate Zone at coordinates 36.0428, -89.3916, presents a moderately favorable environment for solar PV energy generation throughout the year. The location experiences distinct seasonal variations in solar energy production, with peak performance during the summer months.

Seasonal Solar Production

Solar energy output in Dyersburg fluctuates significantly across the seasons. Summer stands out as the most productive period, with an average daily output of 6.72 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.72 kWh/day. Autumn sees a noticeable decrease in production at 4.30 kWh/day, while winter experiences the lowest output at 2.49 kWh/day.

The substantial difference between summer and winter production highlights the importance of proper system sizing to ensure adequate energy supply during less productive months. Despite the winter lull, the location still offers viable year-round solar potential, particularly from late spring through early fall.

Optimal Panel Installation

To maximize year-round solar energy production in Dyersburg, 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 Dyersburg's climate is generally conducive to solar energy production, there are some environmental factors to consider:

• Occasional severe weather: Tennessee can experience thunderstorms, tornadoes, and occasional ice storms, which may temporarily impact solar production or potentially damage equipment.
• Humidity and air quality: The region's humidity and occasional haze could slightly reduce solar panel efficiency.

To mitigate these factors, consider installing robust mounting systems designed to withstand high winds, using panels with anti-reflective coatings to improve performance in diffuse light conditions, and implementing a regular cleaning schedule to maintain optimal panel efficiency.

Overall, while Dyersburg may not offer the ideal conditions found in sun-drenched desert locations, it still presents a viable opportunity for solar energy production. With proper system design and maintenance, solar PV installations in this area can provide significant energy output, particularly during the extended daylight hours of late spring, summer, and early fall.

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 Dyersburg

Seasonal solar PV output for Latitude: 36.0428, Longitude: -89.3916 (Dyersburg, 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 Dyersburg, United States

To maximize your solar PV system's energy output in Dyersburg, United States (Lat/Long 36.0428, -89.3916) 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 Dyersburg, 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 Dyersburg, 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 Dyersburg, 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 Dyersburg, 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 Dyersburg, United States

The topography around Dyersburg, United States, located at latitude 36.0428 and longitude -89.3916, is characterized by a relatively flat landscape typical of the Mississippi River Valley region. This area, situated in northwestern Tennessee, is part of the Gulf Coastal Plain, which extends from the Appalachian Mountains to the Gulf of Mexico. The terrain surrounding Dyersburg is predominantly low-lying and gently rolling, with elevations generally ranging from 250 to 300 feet above sea level. The landscape is dotted with agricultural fields, small woodlands, and numerous streams and rivers that flow towards the Mississippi River, which lies about 20 miles to the west of Dyersburg.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat to gently sloping terrain in the region surrounding Dyersburg offers favorable conditions for solar farm development. Areas to the east and southeast of Dyersburg, where there are expansive agricultural lands, could be particularly well-suited for solar PV projects. These areas typically have fewer obstructions that could cast shadows on solar panels, such as tall buildings or dense forests. The open fields provide ample space for large arrays of solar panels and allow for optimal positioning to capture sunlight throughout the day. Additionally, the existing road infrastructure in these agricultural areas could facilitate the transportation of equipment and materials necessary for solar farm construction and maintenance. It's worth noting that while the topography is generally suitable, other factors such as proximity to electrical grid infrastructure, local zoning regulations, and environmental considerations would also need to be taken into account when determining the most appropriate locations for large-scale solar PV installations in the vicinity of Dyersburg.

United States solar PV Stats as a country

United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in United States?

Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
