Clearfield, Pennsylvania, located in the Northern Temperate Zone, presents a moderately favorable location for 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 varies dramatically throughout the year. Summer provides the strongest performance at 5.94 kWh per day per kW of installed solar capacity, making it an excellent time for solar generation. Spring follows as the second-best season with 5.03 kWh per day per kW, offering nearly comparable performance to summer months. Autumn shows a notable decline to 3.07 kWh per day per kW, while winter presents the most challenging conditions with only 1.76 kWh per day per kW of installed capacity. This represents more than a three-fold difference between peak summer and winter production.

Optimal Installation Configuration

For maximum year-round energy production at Clearfield, solar panels should be installed at a fixed tilt angle of 35 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying position throughout the year and weighting the angles based on solar irradiance data.

Local Factors Affecting Solar Production

Several environmental and weather factors in the Clearfield area can significantly impact solar energy production:

• Snow accumulation: Pennsylvania winters bring substantial snowfall that can completely block solar panels for days or weeks
• Cloud cover: The region experiences frequent overcast conditions, particularly during autumn and winter months
• Tree coverage: The heavily forested Pennsylvania landscape can create shading issues
• Humidity and haze: Summer humidity can reduce solar efficiency and create atmospheric haze

Preventative Measures for Better Performance

Several installation strategies can help maximize solar production despite these challenges:

• Steeper panel angles: Installing panels at angles slightly steeper than the optimal 35 degrees can help snow slide off more easily
• Strategic placement: Careful site selection away from large trees and on south-facing slopes can minimize shading
• Snow removal systems: Consider installing heating elements or designing easy access for manual snow removal
• Quality equipment: Choose panels and inverters rated for cold weather performance and humidity resistance
• Regular maintenance: Schedule cleaning and inspection services to remove debris, leaves, and other obstructions

While Clearfield's winter performance is quite limited, the strong spring and summer production can still make solar installations economically viable, especially when combined with proper installation techniques and maintenance practices.

Solar output per kW of installed solar PV by season in Clearfield, Pennsylvania

Seasonal solar PV output for Latitude: 41.0217, Longitude: -78.4418 (Clearfield, Pennsylvania, 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 35° South in Clearfield, Pennsylvania, United States

To maximize your solar PV system's energy output in Clearfield, Pennsylvania, United States (Lat/Long 41.0217, -78.4418) throughout the year, you should tilt your panels at an angle of 35° 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 Clearfield, Pennsylvania, 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 Clearfield, Pennsylvania, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
25° South in Summer	45° South in Autumn	56° South in Winter	34° 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 Clearfield, Pennsylvania, 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 Clearfield, Pennsylvania, 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 Clearfield, Pennsylvania, United States

Topographical Features Around Clearfield

The landscape surrounding Clearfield, Pennsylvania is characterized by the rolling hills and valleys typical of the Appalachian Plateau region. This area sits within the broader Allegheny Mountains system, where elevations generally range from around 1,000 to 2,000 feet above sea level. The terrain features a mix of forested ridges, agricultural valleys, and cleared plateaus that have been shaped by centuries of water erosion and glacial activity. The immediate vicinity of Clearfield displays relatively moderate topographical variation compared to more mountainous regions of Pennsylvania. While the area does contain hills and ridges, many slopes are gradual rather than steep, creating a landscape that undulates gently across much of the region. This topography has historically supported both farming and forestry activities, indicating that significant portions of the land have manageable gradients. Several major waterways flow through the region, including the West Branch Susquehanna River and various tributaries that have carved valleys and floodplains into the landscape. These river valleys often contain the flattest terrain in the area, though they may be subject to periodic flooding and are frequently used for agriculture or development.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Clearfield would be the elevated plateaus and gently sloping hillsides that face southward. These areas combine several advantageous characteristics: they typically have been cleared of forest cover for agricultural use, they offer good drainage, and their elevation provides fewer obstructions from surrounding terrain features. The agricultural valleys, particularly those running east-west, present excellent opportunities for solar development. These areas often contain large, relatively flat parcels of land that have already been cleared and are easily accessible by existing road networks. The valley floors and lower slopes generally have gentle gradients that would minimize grading requirements for solar panel installation. Former mining areas and industrial sites scattered throughout the region may also provide suitable locations for solar development. These previously disturbed lands often have the advantage of being already cleared and may have existing electrical infrastructure nearby. Many such sites have relatively level terrain following reclamation efforts. Ridge tops and elevated plateaus that have been cleared for agriculture or other uses can be particularly attractive for solar installations. These locations typically receive excellent solar exposure with minimal shading from surrounding terrain. However, developers would need to consider factors such as wind exposure and accessibility when evaluating these higher elevation sites. The key consideration for any large-scale solar development in this region would be identifying parcels with minimal tree cover, southern-facing orientations, and gentle slopes that would not require extensive site preparation. Areas with existing utility infrastructure and good road access would be particularly well-suited for commercial solar projects.
