Marysville, Pennsylvania, located in the Northern Temperate Zone, offers a moderate potential for solar energy generation throughout the year. The location's seasonal variations in solar output provide both opportunities and challenges for solar PV installations.
Seasonal Solar Performance
Solar energy production in Marysville fluctuates significantly across the seasons. Summer stands out as the most productive period, with an impressive 6.07 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.31 kWh/day. However, autumn sees a considerable drop to 3.33 kWh/day, while winter experiences the lowest output at just 2.04 kWh/day.
Optimal Times for Solar Generation
The most favorable months for solar energy production in Marysville are typically from late spring through early fall. This period, roughly from May to September, offers longer daylight hours and generally clearer skies, maximizing solar panel efficiency. However, even during the less productive winter months, modern solar technologies can still harness a meaningful amount of energy.
Panel Tilt Optimization
To maximize year-round solar production in Marysville, fixed solar panels should be installed at a 35-degree tilt angle facing south. This optimal angle allows for efficient energy capture throughout the year, balancing the sun's varying positions across seasons.
Environmental and Weather Considerations
While Marysville's climate is generally conducive to solar energy production, there are some factors that could impact efficiency:
- Snow accumulation in winter can temporarily reduce panel output
- Cloudy days, particularly common in late fall and winter, may decrease production
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and use high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal and panel cleaning, can also help maintain optimal performance.
Overall, while Marysville may not offer ideal year-round conditions for solar energy production, it still presents a viable location for solar PV installations with proper planning and maintenance.

Solar output per kW of installed solar PV by season in Marysville, Pennsylvania
Seasonal solar PV output for Latitude: 40.3426, Longitude: -76.93 (Marysville, 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 Marysville, Pennsylvania, United States
To maximize your solar PV system's energy output in Marysville, Pennsylvania, United States (Lat/Long 40.3426, -76.93) 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 Marysville, 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 Marysville, 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 |
|---|---|---|---|
| 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 Marysville, 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 Marysville, Pennsylvania, 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 Marysville, Pennsylvania, United States
The topography around Marysville, Pennsylvania, located at approximately 40.3426 degrees north latitude and 76.93 degrees west longitude, is characterized by a mix of gently rolling hills and flat river valleys. This area is situated in the eastern part of the state, near the Susquehanna River, which has played a significant role in shaping the local landscape over millennia. The immediate vicinity of Marysville features relatively low-lying terrain, with elevations generally ranging from about 300 to 600 feet above sea level. The town itself is nestled along the western bank of the Susquehanna River, which forms a prominent feature of the local topography. The river valley provides a wide, flat area that contrasts with the surrounding hills. To the west and northwest of Marysville, the land gradually rises into the foothills of the Appalachian Mountains. These hills become more pronounced as one moves further west, eventually transitioning into the Ridge-and-Valley Appalachians. This region is characterized by long, parallel ridges and valleys that run in a northeast-southwest direction.
Potential Areas for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. Ideal locations for solar farms typically require large, flat or gently sloping areas with good sun exposure and minimal shading. The flat river valleys in the region, particularly those along the Susquehanna River, could potentially offer suitable sites for solar PV installations. These areas often have the advantage of being relatively level, which can reduce construction costs and simplify the installation process. However, it's important to consider potential flooding risks in these low-lying areas. The gently rolling hills to the west and northwest of Marysville might also provide good opportunities for solar farms. South-facing slopes in particular could offer excellent sun exposure throughout the day. These elevated areas may also be less prone to morning fog or mist that can sometimes accumulate in river valleys, potentially reducing solar efficiency. Former agricultural lands or brownfield sites in the surrounding area could be prime candidates for solar development. These locations often provide large, open spaces that are already cleared of trees and have existing road access. It's worth noting that while the topography around Marysville offers potential for solar PV development, other factors such as local zoning regulations, proximity to electrical infrastructure, and environmental considerations would also need to be taken into account when determining the most suitable locations for large-scale solar installations.United States solar PV Stats as a country
