Solar PV Analysis of Keller, United States
Keller, Texas, located in the Northern Sub Tropics at latitude 32.9275 and longitude -97.2512, offers a generally favorable environment for solar PV energy generation throughout the year. The location experiences significant seasonal variations in solar output, which can affect the overall efficiency and effectiveness of solar installations.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Keller, with an impressive average daily output of 7.00 kWh per kW of installed solar capacity. This high performance is due to longer daylight hours and more direct sunlight during the summer months.
Spring and autumn also provide good solar generation potential, with daily outputs of 5.43 kWh and 5.05 kWh respectively per kW installed. These transitional seasons offer moderate temperatures and generally clear skies, contributing to efficient solar production.
Winter sees a significant drop in solar output, with an average of 3.31 kWh per day per kW installed. This reduction is primarily due to shorter daylight hours and the sun's lower position in the sky, resulting in less direct sunlight reaching the panels.
Optimal Panel Installation
To maximize year-round solar energy production in Keller, fixed solar panels should be installed at a tilt angle of 29 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the seasonal variations in the sun's position.
Environmental Considerations
While Keller's climate is generally conducive to solar energy production, there are some environmental factors to consider:
- Occasional severe weather events, such as hailstorms or tornadoes, could potentially damage solar panels.
- High summer temperatures may slightly reduce panel efficiency, although this is typically offset by increased sunlight hours.
To mitigate these risks, it's advisable to use high-quality, impact-resistant solar panels and ensure proper installation with sturdy mounting systems. Additionally, regular maintenance and cleaning can help maintain optimal performance, especially during periods of high pollen or dust.
Overall, Keller, Texas provides a suitable location for solar PV installations, with strong potential for energy generation throughout most of the year. The significant seasonal variations highlight the importance of proper system sizing to meet energy needs during less productive winter months while capitalizing on the abundant solar resources available during the rest of the year.

Solar output per kW of installed solar PV by season in Keller
Seasonal solar PV output for Latitude: 32.9275, Longitude: -97.2512 (Keller, 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 Keller, United States
To maximize your solar PV system's energy output in Keller, United States (Lat/Long 32.9275, -97.2512) 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 Keller, 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 Keller, 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 | 27° 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 Keller, 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 Keller, 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 Keller, United States
The topography around Keller, Texas, which is located in the Dallas-Fort Worth metroplex, is generally characterized by gently rolling hills and relatively flat terrain. This area is part of the larger Cross Timbers region, which is known for its mix of prairie grasslands and wooded areas. The landscape is not particularly dramatic or mountainous, but rather consists of subtle elevation changes and open spaces.
The terrain in and around Keller features a blend of small creeks, scattered woodlands, and open fields. The elevation in this area typically ranges from about 600 to 700 feet above sea level, with only minor variations. This gentle topography is a result of the region's geological history, which includes ancient seabeds and sedimentary deposits.
As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the best locations would likely be found in the more rural areas surrounding Keller. Ideal spots for solar farms typically include large, open spaces with minimal shading from trees or buildings. The relatively flat terrain in much of the region surrounding Keller could be advantageous for solar panel placement.
Some of the most promising areas for large-scale solar PV projects might be found to the west and northwest of Keller, where there are more expansive rural and agricultural lands. These areas often have fewer obstructions and larger parcels of land available. Additionally, regions to the south and southwest, towards Fort Worth, might offer suitable locations where urban development is less dense.
It's important to note that while the topography is generally favorable for solar installations, other factors such as local zoning regulations, proximity to electrical infrastructure, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar PV projects in the vicinity of Keller.
