Emory, Texas offers reasonably good conditions for solar energy generation throughout most of the year, though like many locations in the Northern Sub Tropics, it experiences significant seasonal variation in solar output.
Seasonal Solar Performance
Summer represents the peak solar generation period at this location, producing 6.86 kWh per day per kW of installed solar capacity. This makes it an excellent time for maximum energy harvest. Spring follows as the second-best season with 5.25 kWh per day per kW, offering strong solar production as daylight hours increase and weather conditions improve. Autumn sees a notable decline to 4.84 kWh per day per kW as the sun angle decreases and weather patterns shift. Winter presents the most challenging period for solar generation, dropping significantly to just 2.84 kWh per day per kW of installed capacity.Optimal Panel Configuration
For maximum year-round solar energy production at Emory, Texas, solar panels should be installed at a fixed tilt angle of 29 degrees facing south. This angle has been calculated to optimize total annual energy output by accounting for the sun's changing position throughout the seasons and the varying solar irradiance levels at this latitude.Local Factors Affecting Solar Production
Several environmental and weather factors in the Emory area can impact solar panel performance:- Severe thunderstorms and hail are common in East Texas, potentially causing physical damage to solar panels
- High humidity levels can reduce solar efficiency and promote dust and debris accumulation
- Frequent cloud cover during storm seasons can significantly reduce solar irradiance
- Dust and pollen, particularly during spring months, can coat panels and reduce light transmission
- Ice storms, though infrequent, can damage panels or create dangerous cleaning conditions
Preventative Measures for Better Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Install impact-resistant tempered glass panels rated for hail resistance
- Ensure proper drainage and ventilation around panels to combat humidity effects
- Design mounting systems to withstand high winds common during severe weather
- Establish regular cleaning schedules, particularly during high pollen seasons
- Install monitoring systems to quickly identify performance drops due to soiling or damage
- Consider anti-reflective coatings that also resist dirt accumulation
- Maintain adequate spacing between panels for air circulation and easier maintenance access
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Emory
Seasonal solar PV output for Latitude: 32.8746, Longitude: -95.7655 (Emory, 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 29° South in Emory, United States
To maximize your solar PV system's energy output in Emory, United States (Lat/Long 32.8746, -95.7655) throughout the year, you should tilt your panels at an angle of 29° 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 Emory, 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 Emory, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 17° South in Summer | 38° South in Autumn | 48° South in Winter | 26° 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 Emory, 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 Emory, 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 Emory, United States
Topographical Features Around Emory
The landscape surrounding Emory in East Texas is characterized by gently rolling hills and relatively modest elevation changes typical of the East Texas Piney Woods region. This area sits within the transitional zone between the Gulf Coastal Plains and the more elevated terrain found further west in Texas. The topography features a series of low ridges and shallow valleys that create a moderately undulating terrain pattern across the region. The elevation around Emory generally ranges from approximately 350 to 450 feet above sea level, with the terrain sloping gradually toward the southeast in the direction of the Gulf of Mexico. The area is dotted with numerous small creeks and tributaries that flow toward the Sabine River system, creating natural drainage patterns that have carved gentle depressions and valleys throughout the landscape.Vegetation and Land Cover
The natural vegetation consists primarily of mixed pine and hardwood forests, which are characteristic of the East Texas Piney Woods ecoregion. These forested areas are interspersed with cleared agricultural lands, pastures, and residential developments. Many areas have been previously logged or cleared for farming activities, resulting in a patchwork of different land uses across the region. The soil composition includes sandy loams and clay-based soils that support both forest growth and agricultural activities. The relatively stable soil conditions and moderate drainage characteristics make the area suitable for various types of development projects.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be the previously cleared agricultural lands and open pastures scattered throughout the region. These areas offer several advantages, including existing cleared terrain that would minimize environmental impact and reduce preparation costs. The gently sloping topography in these cleared areas provides natural drainage while maintaining relatively flat surfaces suitable for solar panel installation. South-facing slopes with gradual inclines would be particularly advantageous for solar installations, as they can optimize panel orientation while maintaining good drainage characteristics. Areas with elevations on the higher end of the local range would also be preferable, as they tend to have better air circulation and are less prone to fog formation during certain weather conditions. The former agricultural lands northeast and southwest of Emory present some of the best opportunities, as these areas combine suitable topography with existing infrastructure access. These locations typically feature gentle slopes, good drainage, and proximity to existing electrical transmission infrastructure that would be necessary for connecting large-scale solar installations to the power grid. Areas near existing roadways and utility corridors would be most practical for development, as they provide essential access for construction and maintenance activities while offering connection points to electrical transmission systems. The relatively stable soil conditions throughout the region would support the foundation requirements for solar mounting systems without requiring extensive ground preparation in most locations.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.
