Hunlock Creek, Pennsylvania, located in the Northern Temperate Zone, presents a moderately favorable location for year-round 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 shows dramatic seasonal swings that are typical of northern temperate climates. Summer provides the strongest performance at 5.88 kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows as the second-best performing season with 5.11 kWh per day per kW, offering nearly as much energy production as the summer months. Autumn shows a notable decline to 3.05 kWh per day per kW, while winter presents the most challenging conditions with only 1.86 kWh per day per kW of installed solar capacity. This winter output represents less than one-third of the summer production levels, which is a significant consideration for anyone planning to rely heavily on solar energy during the colder months.Optimal Installation Configuration
For fixed panel installations at Hunlock Creek, the ideal tilt angle is 35 degrees facing south to maximize total year-round production. This angle has been calculated to optimize solar collection throughout all seasons by accounting for the sun's changing position and the varying solar irradiance levels throughout the year.Local Environmental and Weather Factors
Several environmental and weather factors in the Hunlock Creek area can significantly impact solar energy production:- Snow accumulation: Pennsylvania winters typically bring substantial snowfall that can completely block solar panels, eliminating energy production until the snow melts or is removed
- Cloud cover and precipitation: The region experiences frequent overcast conditions, particularly during autumn and winter months, which reduces solar irradiance
- Deciduous tree coverage: The area's abundant deciduous forests can create shading issues, especially when trees are in full leaf during spring and summer
- Temperature effects: While cold temperatures can actually improve solar panel efficiency, the combination of short days and frequent cloud cover in winter outweighs this benefit
Preventative Measures for Optimal Performance
Several installation strategies can help maximize solar energy production despite these challenges:- Steep panel angles: Installing panels at steeper angles (like the recommended 35 degrees) helps snow slide off more easily
- Strategic site selection: Choose installation locations with minimal shading from trees, particularly avoiding areas with large deciduous trees to the south
- Panel spacing: Proper spacing between panel rows prevents self-shading and allows better snow clearance
- Regular maintenance: Plan for periodic snow removal during heavy winter storms and keep panels clean of debris
- Quality equipment: Use panels and mounting systems rated for heavy snow loads and temperature extremes typical of Pennsylvania winters
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 35° South in Hunlock Creek, United States
To maximize your solar PV system's energy output in Hunlock Creek, United States (Lat/Long 41.2059, -76.066) 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 Hunlock Creek, 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 Hunlock Creek, 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.

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 Hunlock Creek, United States.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Hunlock Creek, United States
Topographical Features Around Hunlock Creek
Hunlock Creek sits within the Wyoming Valley region of northeastern Pennsylvania, nestled in a landscape shaped by both ancient geological forces and more recent glacial activity. The area features rolling hills and gentle ridges that are characteristic of the northern Appalachian foothills. The terrain around this location displays moderate elevation changes, with the immediate vicinity sitting at approximately 600 feet above sea level.
The topography is dominated by the Susquehanna River valley system, which creates broad, relatively flat bottomlands interspersed with low hills and ridges. These ridges generally run in a northeast-southwest orientation, following the grain of the underlying rock formations. The landscape shows evidence of glacial modification, with rounded hilltops and U-shaped valleys that have been softened from their original sharp profiles.
Local drainage patterns flow toward the Susquehanna River, creating a network of small creeks and streams that have carved modest valleys through the terrain. The area's geology consists primarily of sedimentary rocks, including sandstone and shale formations that weather to create moderately fertile soils on the gentler slopes and valley floors.
Optimal Areas for Large-Scale Solar Development
The most promising locations for substantial solar photovoltaic installations lie on the broad, south-facing slopes that characterize much of the region's rolling terrain. These areas benefit from excellent solar exposure while maintaining relatively gentle gradients that minimize construction challenges and reduce installation costs. The agricultural fields scattered throughout the valley bottoms also present excellent opportunities, as they typically feature minimal tree cover and already cleared, level ground.
The ridge tops and upper slopes facing south and southwest represent particularly attractive sites for solar development. These elevated positions not only capture optimal sunlight throughout the day but also tend to have fewer obstructions from surrounding vegetation or structures. The moderate elevation changes in the area mean that even ridge-top installations remain accessible for construction equipment and maintenance vehicles.
Former agricultural lands and open meadows in the broader valley areas offer additional advantages for large-scale solar projects. These locations typically have established road access, existing electrical infrastructure nearby, and soil conditions that can easily accommodate ground-mounted solar arrays. The relatively stable geology of the region, built on sedimentary bedrock, provides solid foundations for solar installations without the complications that might arise in areas with unstable soils or steep slopes.
Areas to avoid for solar development include the narrow valley bottoms where morning and evening shadows from surrounding hills could impact energy production, as well as the steeper north-facing slopes that receive less direct sunlight throughout the year. Forested areas, while potentially suitable if cleared, would require additional environmental considerations and higher development costs compared to already open land.
