Murray, Kentucky, located in the Northern Temperate Zone, offers a moderate potential for solar energy generation throughout the year. The location's solar productivity varies significantly across seasons, with peak performance during the summer months.
Seasonal Solar Output
Summer stands out as the most productive season, with an average daily output of 6.52 kWh per kW of installed solar capacity. Spring follows closely, generating 5.64 kWh/day. Autumn sees a noticeable decrease to 4.14 kWh/day, while winter experiences the lowest output at 2.46 kWh/day.
Ideal Generation Periods
The most favorable time for solar energy production in Murray is from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. However, even in winter, the panels continue to generate a meaningful amount of electricity, albeit at a reduced rate.
Optimal Panel Tilt
For fixed panel installations in Murray, the ideal tilt angle to maximize year-round solar production is 32 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for seasonal variations in the sun's position.
Environmental and Weather Considerations
While Murray'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 in spring and summer
- Periodic ice storms and snow in winter
To mitigate these challenges, solar installations should include robust mounting systems capable of withstanding high winds. Additionally, panels should be installed at an angle that facilitates snow and ice shedding. Regular cleaning and maintenance can help ensure optimal performance, especially after storms or prolonged periods of inclement weather.
Overall, while Murray experiences seasonal fluctuations in solar energy production, its location in the Northern Temperate Zone provides a reasonable foundation for solar PV systems, particularly when proper installation techniques and maintenance practices are employed.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Murray
Seasonal solar PV output for Latitude: 36.6089, Longitude: -88.3031 (Murray, 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 32° South in Murray, United States
To maximize your solar PV system's energy output in Murray, United States (Lat/Long 36.6089, -88.3031) throughout the year, you should tilt your panels at an angle of 32° 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 Murray, 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 Murray, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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 Murray, 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 Murray, United States.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Murray, United States
The area around Murray, Kentucky in the United States features a relatively flat to gently rolling landscape typical of the Jackson Purchase region. This westernmost part of Kentucky is characterized by low hills, broad river valleys, and expansive agricultural fields. The terrain gradually slopes downward from east to west towards the Mississippi River, with elevations typically ranging from about 350 to 600 feet above sea level. Murray itself sits on a slightly elevated plain, with subtle undulations in the surrounding countryside. The land is primarily composed of fertile soil deposits left behind by ancient flooding of nearby rivers. Small streams and creeks crisscross the area, creating shallow valleys between the low ridges and hills.
Nearby Areas Suitable for Large-Scale Solar PV
For large-scale solar photovoltaic (PV) installations, the regions to the west and southwest of Murray offer the most promise. These areas feature vast stretches of open farmland with minimal tree cover, providing ample space and unobstructed exposure to sunlight. The gently sloping terrain in this direction is ideal for solar panel placement, allowing for optimal angling towards the sun without significant earthwork. Specifically, the agricultural lands between Murray and Mayfield, extending towards the Kentucky-Tennessee border, present excellent opportunities for solar development. These areas benefit from relatively flat topography, good road access, and proximity to existing power infrastructure. It's worth noting that while the entire region receives adequate sunlight for solar power generation, care must be taken to avoid flood-prone areas near rivers and major creeks. Additionally, any solar projects would need to balance land use with the region's strong agricultural heritage. Overall, the topography and land use patterns around Murray make it a promising location for large-scale solar PV development, particularly in the open spaces to the west and southwest of the city.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.
