Perry, Oklahoma, located in the Northern Temperate Zone, offers a moderately favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies significantly, with peak production occurring during the summer months.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive daily output of 7.14 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.52 kWh/day. Autumn sees a decrease in production to 4.72 kWh/day, while winter experiences the lowest output at 3.12 kWh/day.

The substantial variation between summer and winter production highlights the impact of seasonal changes on solar energy generation in Perry. This location experiences its peak solar potential from late spring through early fall, making it an ideal time for maximizing solar energy harvesting.

Optimal Panel Installation

For fixed panel installations in Perry, the ideal tilt angle to maximize year-round solar production is 32 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental and Weather Considerations

While Perry's location is generally suitable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

1. Severe thunderstorms and tornadoes: Oklahoma is prone to extreme weather events, particularly during spring and early summer. These storms can potentially damage solar installations if not properly secured.
2. Dust and pollen: The region's agricultural activities and natural vegetation can lead to dust and pollen accumulation on solar panels, reducing their efficiency.

Preventative Measures

To mitigate these potential issues and ensure optimal solar energy production, consider implementing the following measures:

• Install robust mounting systems designed to withstand high winds and severe weather conditions.
• Implement a regular cleaning schedule for solar panels to remove dust, pollen, and other debris.
• Consider installing a monitoring system to track performance and quickly identify any issues affecting energy production.

By addressing these factors and optimizing panel placement, Perry, Oklahoma can effectively harness solar energy throughout the year, with particularly strong performance during the summer months.

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

Seasonal solar PV output for Latitude: 36.2882, Longitude: -97.2854 (Perry, 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 32° South in Perry, Oklahoma, United States

To maximize your solar PV system's energy output in Perry, Oklahoma, United States (Lat/Long 36.2882, -97.2854) throughout the year, you should tilt your panels at an angle of 32° 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 Perry, 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 Perry, Oklahoma, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
20° South in Summer	41° South in Autumn	51° South in Winter	30° 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 Perry, 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 Perry, 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 Perry, Oklahoma, United States

Perry, Oklahoma, situated in the north-central part of the state, is characterized by gently rolling plains and prairie landscapes typical of the Great Plains region. The topography around Perry is relatively flat to slightly undulating, with occasional low hills and shallow valleys. The area's elevation generally ranges from about 900 to 1,100 feet above sea level, with minimal dramatic changes in elevation. The landscape surrounding Perry is primarily composed of open grasslands and agricultural fields, interspersed with patches of deciduous woodlands, particularly along streams and rivers. The Cimarron River, which flows to the south of Perry, has carved a shallow valley through the otherwise level terrain, creating some minor variations in the local topography.

Suitability for Large-Scale Solar PV

The areas surrounding Perry offer several advantages for large-scale solar photovoltaic (PV) installations. The relatively flat terrain and abundance of open spaces make it easier to construct and maintain solar arrays without the need for extensive land preparation or terracing. Additionally, the region receives ample sunlight throughout the year, which is crucial for solar energy production. The most suitable areas for large-scale solar PV near Perry would likely be found in the expansive agricultural lands to the north, east, and west of the city. These areas offer large, unobstructed plots of land with minimal shading from trees or buildings. The gently sloping terrain in these directions also provides good drainage and reduces the risk of flooding, which is beneficial for solar installations. Areas to the south of Perry, closer to the Cimarron River, may be less ideal due to the increased likelihood of trees and slightly more varied topography. However, carefully selected sites in this direction could still be suitable, particularly if they are situated on higher ground away from the river's immediate vicinity. It's worth noting that while the topography around Perry is generally favorable for solar PV, other factors such as proximity to existing power infrastructure, local zoning regulations, and environmental considerations would also need to be taken into account when determining the most suitable locations for large-scale solar installations.
