For fixed solar panel installations in Collinsville, the ideal tilt angle to maximize year-round energy production is 28 degrees facing South. This angle has been calculated by analyzing solar elevation angles at this specific latitude, determining daily optimal panel tilt, weighting these angles by daily PV potential using NASA's solar irradiance data, and calculating the weighted annual average.Environmental and Weather Considerations
Several environmental factors in Collinsville may impact solar energy production:- Humidity and cloud cover: The subtropical climate brings periods of high humidity and cloud cover, particularly during summer thunderstorm season, which can temporarily reduce solar efficiency.
- Seasonal storms: The area experiences thunderstorms and occasional severe weather that can impact solar production.
- Tree cover and vegetation: The region's natural vegetation can create shading issues if not properly managed.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° 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.

Ideally tilt fixed solar panels 28° South in Collinsville, Mississippi, United States
To maximize your solar PV system's energy output in Collinsville, Mississippi, United States (Lat/Long 32.4979, -88.8459) throughout the year, you should tilt your panels at an angle of 28° 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 Collinsville, Mississippi, 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 Collinsville, Mississippi, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 16° South in Summer | 38° South in Autumn | 47° South in Winter | 25° 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.

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 Collinsville, Mississippi, 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 Collinsville, Mississippi, United States
Topography of Collinsville, Mississippi
Collinsville, Mississippi is situated in the east-central part of the state, in Lauderdale County. The landscape around Collinsville features gently rolling hills and shallow valleys, characteristic of the East Gulf Coastal Plain physiographic region. The terrain gradually transitions from the more rugged Appalachian foothills to the northeast toward the flatter coastal plains to the south and southwest. The area has a moderate relief with elevations typically ranging between 300 and 500 feet above sea level. This undulating landscape has been shaped by the erosion of sedimentary rock formations and the action of numerous small streams and creeks that flow through the region. The North Okatibbee Creek and its tributaries are particularly influential in carving the local topography. The natural vegetation consists primarily of mixed pine and hardwood forests, with areas that have been cleared for agricultural use and human settlement. The soil composition varies but generally includes sandy loams and clay soils with moderate drainage properties.Solar PV Suitability in the Region
When considering locations for large-scale solar photovoltaic (PV) installations near Collinsville, several areas show promise based on topographical features. The gently sloping lands to the south and southwest of Collinsville offer favorable conditions for solar development. These areas benefit from having: Relatively flat terrain with gradual slopes facing south or southwest, which maximizes exposure to the sun's path across the sky. Less dense forest cover in previously cleared agricultural lands, reducing the need for extensive site preparation and vegetation removal. Proximity to existing electrical infrastructure, including transmission lines that run through Lauderdale County, which can significantly reduce interconnection costs. The upland areas between stream valleys provide excellent sites as they tend to have better drainage and reduced flood risk compared to lowland areas. Additionally, the modest elevation changes can be advantageous for solar array placement, allowing for optimal panel orientation without excessive grading requirements. Areas to potentially avoid include the immediate floodplains of North Okatibbee Creek and its tributaries, as well as the more heavily forested sections with steeper slopes to the northeast. These locations would require more extensive site preparation and may present challenges related to erosion control and environmental impact. The combination of available open land, suitable slopes, and relatively stable soil conditions makes the area around Collinsville conducive to solar energy development, particularly in the already disturbed agricultural and pasture lands that feature south-facing gentle slopes.United States solar PV Stats as a country
