Sapulpa, Oklahoma offers a moderate location for solar energy generation, with seasonal variations that affect overall production throughout the year. Located in the Northern Temperate Zone at coordinates 36.0055, -96.1096, this location experiences distinct seasonal differences in solar potential.

Seasonal Solar Production

Solar panels in Sapulpa generate their highest electricity output during summer months, producing an average of 7.04 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.24 kWh/day, while autumn yields 4.52 kWh/day. Winter shows the lowest production at just 2.91 kWh/day per installed kilowatt.

The six-month period from April through September represents the prime solar generation window for Sapulpa, when longer daylight hours and higher sun angles create optimal conditions for photovoltaic electricity production. May through August are particularly strong months, when daily production consistently exceeds 6 kWh per installed kilowatt.

Optimal Panel Installation

For fixed solar panel installations in Sapulpa, the ideal tilt angle to maximize year-round energy production is 32 degrees facing South. This angle optimizes the balance between summer and winter production, accounting for the sun's varying elevation throughout the year and Earth's elliptical orbit.

Environmental and Weather Considerations

Several significant environmental factors can impact solar production in Sapulpa:

• Thunderstorms and severe weather events, common during spring and early summer, can temporarily reduce production and potentially damage equipment if not properly secured
• Winter ice storms may cover panels and halt production until melting occurs
• Moderate snowfall (averaging 9 inches annually) can temporarily reduce winter production
• Oklahoma's dust and pollen can accumulate on panels, gradually reducing efficiency

To mitigate these challenges, installation should include sturdy mounting systems rated for Oklahoma's occasional high winds, self-cleaning panel technologies or regular maintenance schedules, and potentially snow-shedding mounting angles (slightly steeper than the optimal 32 degrees) if winter production is prioritized. Hail-resistant panels are also recommended given the region's propensity for severe thunderstorms during spring and summer.

Overall, while not ideal compared to the American Southwest, Sapulpa's solar potential is sufficient for cost-effective residential and commercial installations with proper system design and maintenance practices.

Solar output per kW of installed solar PV by season in Sapulpa

Seasonal solar PV output for Latitude: 36.0055, Longitude: -96.1096 (Sapulpa, 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 Sapulpa, United States

To maximize your solar PV system's energy output in Sapulpa, United States (Lat/Long 36.0055, -96.1096) 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 Sapulpa, 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 Sapulpa, 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	40° South in Autumn	51° 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 Sapulpa, 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 Sapulpa, 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 Sapulpa, United States

Sapulpa, Oklahoma is situated in a region characterized by gently rolling hills and modest elevation changes typical of northeastern Oklahoma's terrain. Located at the eastern edge of the Great Plains and nestled in the foothills of the Ozark Mountains, the landscape around Sapulpa features a mix of open prairies, wooded areas, and shallow valleys carved by local waterways. The topography around Sapulpa generally consists of elevations ranging from approximately 600 to 900 feet above sea level. The land undulates with a series of low hills and ridges, particularly to the east where the terrain becomes more pronounced as it transitions toward the Ozark Plateau. To the west, the landscape gradually flattens into the prairie lands characteristic of central Oklahoma. Several waterways influence the local topography, with Polecat Creek and Rock Creek being notable examples that have carved shallow valleys through the area. These creeks are part of the Arkansas River watershed, with the Arkansas River itself flowing several miles to the northeast of Sapulpa.

Vegetation and Land Use

The natural vegetation around Sapulpa consists of a mix of tallgrass prairie and cross timbers forest—a mosaic of oak woodlands and grasslands. This creates a diverse landscape with open areas interspersed with clusters of deciduous trees. Much of the original vegetation has been modified by human activities, with significant portions converted to agricultural use, urban development, and oil production facilities, reflecting the region's history as part of Oklahoma's oil boom.

Solar PV Potential in the Region

For large-scale solar photovoltaic (PV) development, several areas near Sapulpa offer promising conditions. The most suitable locations would generally be: The flatter prairie lands to the west and southwest of Sapulpa present the most favorable topography for large-scale solar installations. These areas offer relatively level terrain that would minimize grading costs and engineering challenges during construction. The reduced tree cover in these prairie regions also means less vegetation clearance would be required, lowering both environmental impact and development costs. Former agricultural lands throughout Creek County that are no longer in active production could be ideal candidates for solar development. These areas typically feature cleared, open spaces with established access roads and minimal slope, reducing development costs significantly. Reclaimed oil and gas production sites in the region represent another opportunity. The Sapulpa area has a long history of petroleum production, and many former extraction sites have already been disturbed, making them potentially suitable for repurposing as solar energy facilities with minimal additional environmental impact. Areas along major transportation corridors, such as land adjacent to Interstate 44 and Highway 75, might offer advantages for solar development due to existing infrastructure access and proximity to transmission lines, though careful siting would be necessary to avoid issues with road glare.

Challenges and Considerations

While the region does offer potential for solar development, developers would need to consider several topographical challenges. The rolling nature of the terrain in many areas would require careful site selection to minimize grading requirements. Additionally, the numerous small creeks and associated floodplains would need to be avoided, limiting some potential development areas. The cross timbers woodlands, particularly to the east of Sapulpa, would be less suitable for solar development due to the increased costs and environmental impacts associated with clearing mature trees. These areas also tend to have more pronounced hills and ravines that would complicate construction. Weather considerations are also important for solar development in this region. While Oklahoma receives abundant sunshine, the area is prone to severe weather including thunderstorms, tornadoes, and occasional ice storms, all of which would need to be factored into the design and engineering of any large-scale solar facility.
