Carnegie, Oklahoma, located in the Northern Temperate Zone, presents a moderately favorable location for year-round solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The solar energy output at this location shows typical patterns for the Northern Temperate Zone, with summer providing the highest generation at 7.30 kWh per day per kW of installed capacity. Spring offers good production at 5.79 kWh per day, while autumn drops to 4.94 kWh per day. Winter presents the most challenging period with only 3.29 kWh per day, representing less than half of summer production. Summer clearly emerges as the ideal time for solar generation at Carnegie, followed by spring. The substantial drop-off during winter months means that systems designed for this location need to account for significantly reduced output during approximately four months of the year.

Optimal Panel Configuration

For fixed panel installations at Carnegie, the ideal tilt angle is 31 degrees facing south to maximize total year-round production. This angle represents the optimal compromise across all seasons, calculated using weighted solar elevation angles and irradiance data throughout the year.

Local Environmental and Weather Challenges

Carnegie, Oklahoma faces several significant environmental factors that can impede solar production:

• Severe Weather Events: Oklahoma sits in "Tornado Alley" and experiences frequent severe thunderstorms, hail, and tornadoes that can damage solar panels
• High Winds: The region experiences strong winds year-round, with particularly intense periods during storm seasons
• Dust and Agricultural Debris: The rural, agricultural setting means panels can accumulate dust, pollen, and crop residue, reducing efficiency
• Temperature Extremes: Hot summers can reduce panel efficiency, while rapid temperature changes stress equipment

Preventative Measures for Enhanced Production

Several installation strategies can help mitigate these challenges and improve energy production:

• Impact-Resistant Panels: Choose panels rated for hail impact and high wind loads, typically certified for winds exceeding 140 mph
• Robust Mounting Systems: Install heavy-duty racking systems with proper anchoring designed for high wind zones
• Regular Cleaning Schedule: Implement quarterly cleaning routines to remove dust and debris, particularly important during harvest seasons
• Adequate Ventilation: Ensure proper airflow beneath panels to reduce heat buildup and maintain efficiency during hot summers
• Professional Installation: Use certified installers familiar with Oklahoma's specific weather challenges and local building codes

Despite these challenges, Carnegie's location still offers reasonable solar potential, particularly during the longer, sunnier months. With proper planning and installation techniques that account for local conditions, solar installations can perform effectively while withstanding the region's demanding weather patterns.

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 Carnegie

Seasonal solar PV output for Latitude: 35.1037, Longitude: -98.6037 (Carnegie, 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 Carnegie, United States

To maximize your solar PV system's energy output in Carnegie, United States (Lat/Long 35.1037, -98.6037) 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 Carnegie, 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 Carnegie, 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
19° South in Summer	40° South in Autumn	50° 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 Carnegie, 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 Carnegie, 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 Carnegie, United States

Topography Around Carnegie, Oklahoma

Carnegie sits in the heart of southwestern Oklahoma, positioned within the Great Plains region where the landscape is characterized by gently rolling prairie terrain. The area around Carnegie features relatively flat to mildly undulating topography, with elevations typically ranging from approximately 1,400 to 1,600 feet above sea level. This region represents part of the broader Southern Great Plains, where ancient sedimentary rocks lie beneath layers of fertile soil deposited over millennia. The immediate vicinity of Carnegie is dominated by agricultural land, with vast expanses of wheat fields, pastureland, and some cotton cultivation. The terrain slopes very gradually, creating natural drainage patterns that flow generally eastward toward the Washita River system. Small creeks and seasonal waterways cut shallow valleys through the landscape, but these features create only minor variations in the otherwise predominantly flat topography.

Geological Foundation and Land Features

The underlying geology consists primarily of Permian-age sedimentary rocks, including sandstone, shale, and limestone formations that provide a stable foundation. These rock layers are typically overlain by deep soils that have developed over thousands of years, creating the rich agricultural base that characterizes much of the region. The area experiences minimal seismic activity and has no significant geological hazards that would complicate large-scale development projects. Natural vegetation in undeveloped areas consists mainly of mixed-grass prairie species, though much of the original prairie has been converted to agricultural use. Small patches of native grassland remain, particularly in areas less suitable for cultivation or along creek bottoms where cottonwood and other riparian trees grow.

Optimal Areas for Large-Scale Solar Development

The topography around Carnegie presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas would be the extensive flat to gently sloping agricultural lands that surround the town in all directions. These areas offer several advantages including minimal grading requirements, excellent accessibility for construction and maintenance vehicles, and proximity to existing electrical infrastructure. Particularly promising locations would be the broad, level expanses to the north and east of Carnegie, where the terrain is exceptionally flat and currently used primarily for dryland farming or cattle grazing. These areas would require minimal site preparation and could accommodate very large solar arrays with optimal spacing between panel rows. The gentle topography allows for efficient panel orientation and minimizes shading issues that can occur in more varied terrain. The areas southwest of Carnegie also present good opportunities, though some locations may require more careful site selection to avoid seasonal drainage areas. The relatively uniform elevation across these expanses means that large installations could be designed with consistent panel angles and spacing, maximizing efficiency and reducing installation complexity. Transportation access throughout the region is generally good, with state highways and county roads providing adequate infrastructure for bringing in equipment and materials. The existing agricultural road network would facilitate access to most potential development sites, though some improvement might be needed for the heaviest construction equipment. The stable geological conditions and minimal topographic variation make this region particularly well-suited for the concrete foundations and mounting systems required for utility-scale solar installations. The absence of significant slopes, rocky outcrops, or unstable soils reduces both construction costs and long-term maintenance concerns.
