Wynnewood, Pennsylvania, located in the Northern Temperate Zone, offers a moderately favorable location for solar PV energy generation, though with significant seasonal variations.

Seasonal Solar Production

Solar energy output at this location follows a predictable seasonal pattern. Summer is the most productive season, generating an average of 5.96 kWh per day for each kilowatt of installed capacity. Spring follows closely behind with 5.32 kWh/day per kW installed. Production drops considerably during autumn to 3.36 kWh/day, while winter sees the lowest output at just 2.07 kWh/day per kW installed.

This pattern creates a roughly 3:1 ratio between the best and worst seasons, with summer producing nearly three times the energy of winter months. This substantial seasonal variation is typical for locations in the Northern Temperate Zone like Wynnewood.

Optimal Panel Installation

For fixed-panel installations in Wynnewood, the ideal tilt angle to maximize year-round production is 34 degrees facing South. This angle represents the best compromise between capturing low-angle winter sun and the higher summer sun path.

Environmental and Weather Considerations

Several factors may impact solar production in Wynnewood. Pennsylvania experiences frequent cloud cover throughout the year, particularly during winter months when production is already at its lowest. The region also receives significant snowfall, which can temporarily cover panels and reduce output unless removed.

Tree coverage is another consideration in this suburban Philadelphia location. Mature trees, especially deciduous varieties, may cast shadows across panels during part of the day, though leaf drop in winter partially mitigates this issue when the sun is already at its lowest angle.

To maximize production despite these challenges, consider these preventative measures:

• Install panels on south-facing roof sections whenever possible
• Use microinverters or power optimizers to minimize the impact of partial shading
• Implement a snow removal plan for winter months
• Consider selective tree trimming to reduce shading (while maintaining shade benefits for home cooling)
• Regular panel cleaning to remove pollen, leaves and other debris common in this suburban setting

With proper installation addressing these factors, a solar PV system in Wynnewood can still provide substantial renewable energy, particularly during the half of the year spanning spring and summer seasons.

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

Seasonal solar PV output for Latitude: 40.0021, Longitude: -75.2724 (Wynnewood, 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 34° South in Wynnewood, United States

To maximize your solar PV system's energy output in Wynnewood, United States (Lat/Long 40.0021, -75.2724) throughout the year, you should tilt your panels at an angle of 34° 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 Wynnewood, 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 Wynnewood, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
24° South in Summer	44° South in Autumn	55° South in Winter	33° 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 Wynnewood, 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 Wynnewood, 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 Wynnewood, United States

The area around Wynnewood, Pennsylvania, sits within the southeastern portion of the state, nestled in the Piedmont plateau region of the eastern United States. This location features gently rolling hills and shallow valleys, with elevations generally ranging between 200 and 400 feet above sea level. The topography is characterized by modest slopes rather than steep terrain, creating a landscape that transitions gradually between higher and lower points. Wynnewood itself lies in Lower Merion Township, Montgomery County, within the greater Philadelphia metropolitan area. The natural landscape has been significantly modified by suburban development, with residential neighborhoods, commercial areas, and transportation infrastructure covering much of the original terrain. Despite this development, the underlying topography still influences the area's drainage patterns and viewsheds.

Surrounding Landforms

To the east of Wynnewood flows the Schuylkill River, which has carved a shallow valley through the region as it makes its way toward its confluence with the Delaware River. This river valley represents one of the more significant topographical features in the vicinity. The land generally slopes gently toward this river valley from the west. Small streams and creeks, including Mill Creek and Indian Creek, have created minor valleys throughout the area, adding texture to the otherwise modest relief. These waterways have historically influenced settlement patterns and continue to affect land use decisions today.

Potential for Solar PV Development

When considering areas near Wynnewood for large-scale solar photovoltaic (PV) installations, several factors related to topography become important. The modest slopes throughout much of the region could be advantageous for solar development, as they provide natural drainage while not being so steep as to complicate construction or increase erosion risks. The most suitable areas for large-scale solar PV would be found in the flatter portions of the region, particularly in the less developed areas to the west and northwest of Wynnewood. These areas, extending toward Chester County, feature some agricultural and open lands with favorable topographical characteristics for solar arrays: relatively flat terrain with minimal shading from landforms. Areas to avoid would include the steeper slopes near stream valleys, flood-prone lowlands along the Schuylkill River, and heavily forested areas where clearing would be environmentally disruptive. Additionally, the highly developed suburban landscape immediately surrounding Wynnewood presents challenges for finding contiguous parcels large enough for commercial-scale solar development.

Topographical Considerations for Solar Efficiency

South-facing slopes, even gentle ones, offer natural advantages for solar collection in the Northern Hemisphere. The subtle ridgelines running roughly east-west through portions of the region could provide ideal orientation for solar arrays. These modest elevations also tend to experience less fog accumulation than the lower-lying areas near waterways. The rolling nature of the Piedmont landscape means that careful site selection is necessary to maximize solar exposure throughout the day. While the relief is not dramatic, even modest hills can cast shadows that affect solar productivity, particularly during winter months when the sun angle is lower. In summary, the topography around Wynnewood presents a moderately favorable environment for solar PV development in select areas, with the greatest potential lying in the less developed regions with gentle south-facing slopes away from stream valleys and dense suburban development.
