Elgin, Oklahoma, located in the Northern Sub Tropics, offers a generally favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies significantly, with summer being the most productive period and winter the least.

Seasonal Solar Production

Summer stands out as the peak season for solar energy production in Elgin, with an impressive 7.30 kWh per day for each kW of installed solar capacity. Spring follows as the second most productive season, generating 5.85 kWh/day. Autumn sees a slight decrease to 5.04 kWh/day, while winter experiences the lowest output at 3.32 kWh/day.

This seasonal variation indicates that Elgin's solar potential is strongest from late spring through early fall, making it an ideal time for maximizing solar energy generation. However, the relatively consistent production throughout the year suggests that solar PV systems can provide meaningful energy contributions even during less optimal seasons.

Optimal Panel Tilt

For fixed panel installations in Elgin, the ideal tilt angle to maximize year-round solar production is 31 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's orbit and the location's latitude.

Environmental Considerations

While Elgin's climate is generally conducive to solar energy production, there are some environmental factors to consider:

• Occasional severe weather events, including thunderstorms and tornadoes, which may pose risks to solar installations.
• Dust and pollen accumulation on panels, particularly during dry periods, which can reduce efficiency.

To mitigate these issues, solar installations in Elgin should incorporate sturdy mounting systems designed to withstand high winds. Regular cleaning and maintenance of panels can help maintain optimal efficiency. Additionally, installing a monitoring system can help detect and address any performance issues promptly.

Overall, Elgin's location provides a good balance of solar potential throughout the year, making it a suitable site for solar PV installations with proper planning and maintenance.

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.

Solar output per kW of installed solar PV by season in Elgin, Oklahoma

Seasonal solar PV output for Latitude: 34.7803, Longitude: -98.2923 (Elgin, Oklahoma, 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 Elgin, Oklahoma, United States

To maximize your solar PV system's energy output in Elgin, Oklahoma, United States (Lat/Long 34.7803, -98.2923) 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 Elgin, Oklahoma, 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 Elgin, Oklahoma, 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	39° South in Autumn	50° South in Winter	28° 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 Elgin, Oklahoma, 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 Elgin, Oklahoma, 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 Elgin, Oklahoma, United States

The topography around Elgin, Oklahoma, is characterized by gently rolling plains and prairies typical of the southern Great Plains region. The landscape is predominantly flat to slightly undulating, with occasional low hills and shallow valleys. The area is part of the Red River Valley, which influences its terrain and soil composition. Elgin sits at an elevation of approximately 1,250 feet above sea level. The surrounding countryside gradually slopes downward towards the south and east, where the Red River forms the border between Oklahoma and Texas. To the north and west, the terrain becomes slightly more elevated and rugged as it transitions into the Wichita Mountains. The region's vegetation consists mainly of grasslands and scattered patches of deciduous trees, particularly along creeks and in protected areas. The soil is generally fertile, composed of a mix of clay, silt, and sand, which has made it suitable for agriculture.

Areas Suitable for Large-Scale Solar PV

Several areas near Elgin would be well-suited for large-scale solar photovoltaic (PV) installations. The most promising locations would be: 1. The open plains to the south and east of Elgin: These areas offer vast stretches of flat or gently sloping land with minimal obstructions. The terrain here provides excellent exposure to sunlight throughout the day, making it ideal for solar energy production. 2. Agricultural lands surrounding the town: Many of the farms and ranches in the vicinity have large, open fields that could potentially be repurposed or partially used for solar installations without significantly impacting agricultural productivity. 3. The slightly elevated areas to the north and west: While these locations may have more varied terrain, they still offer ample flat or gently sloping surfaces suitable for solar panels. The higher elevation could potentially provide better exposure to sunlight and reduce the risk of shading from surrounding landscape features. When considering these areas for solar PV development, it's important to take into account factors such as proximity to existing power infrastructure, road access, and potential environmental impacts. Additionally, local zoning regulations and land use policies would need to be carefully reviewed before proceeding with any large-scale solar projects in the region.

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?
