Solar PV Analysis of Aliquippa, United States
Aliquippa, Pennsylvania, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. This location experiences significant seasonal variations in solar output, which affect the overall efficiency of solar PV systems.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 6.10 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.37 kWh/day. These seasons offer ideal conditions for solar energy production, with longer days and more direct sunlight.
Autumn sees a notable decrease in output, dropping to 3.46 kWh/day. Winter presents the biggest challenge, with production plummeting to just 1.84 kWh/day per kW installed. This significant seasonal variation highlights the importance of proper system sizing to meet year-round energy needs.
Optimal Panel Positioning
For fixed panel installations in Aliquippa, the ideal tilt angle to maximize year-round solar production is 35 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the sun's changing position across seasons.
Environmental Considerations
Several environmental factors in Aliquippa can impact solar energy production:
- Snowfall: The region experiences significant snowfall in winter, which can cover panels and reduce output. Regular snow removal and the use of snow-shedding panel designs can mitigate this issue.
- Cloud cover: Aliquippa has many overcast days, particularly in winter. Using high-efficiency panels and micro-inverters can help maximize production even in low-light conditions.
To address these challenges, consider installing panels at a steeper angle to promote snow sliding and using bifacial panels to capture reflected light on cloudy days. Additionally, a robust mounting system is crucial to withstand potential heavy snow loads and occasional strong winds.
While Aliquippa's location presents some challenges for year-round solar energy production, proper system design and maintenance can still make solar PV a viable and beneficial energy option for residents and businesses in the area.

Solar output per kW of installed solar PV by season in Aliquippa
Seasonal solar PV output for Latitude: 40.6367, Longitude: -80.2401 (Aliquippa, 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 Aliquippa, United States
To maximize your solar PV system's energy output in Aliquippa, United States (Lat/Long 40.6367, -80.2401) 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 Aliquippa, 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 Aliquippa, 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 | 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 Aliquippa, 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 Aliquippa, 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 Aliquippa, United States
The topography around Aliquippa, Pennsylvania, is characterized by rolling hills and valleys typical of the Appalachian Plateau region. This area, situated along the Ohio River, features a mix of gently sloping terrain and steeper hillsides. The landscape is a result of long-term erosion of sedimentary rock layers, creating a varied topography with elevations ranging from about 700 to 1,200 feet above sea level.
The immediate vicinity of Aliquippa includes both flat areas near the river and more elevated, hilly sections as you move away from the water. The town itself is nestled in a relatively flat area along the Ohio River, but the surrounding region quickly transitions to more undulating terrain. This varied topography creates a patchwork of different slopes and aspects, with some areas facing south and others facing various other directions.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few key factors to consider. Ideally, solar farms require relatively flat or gently sloping land with good southern exposure to maximize sunlight capture throughout the day. Additionally, areas with minimal shading from surrounding hills or vegetation are preferable.
Given these criteria, the most suitable areas for large-scale solar PV near Aliquippa would likely be found on the broader, flatter hilltops or plateaus in the surrounding region. These areas would offer the advantage of elevation, potentially reducing shading issues from nearby terrain. Some of the more gently sloping south-facing hillsides could also be considered, although they may require more extensive site preparation.
It's important to note that while the topography plays a crucial role in site selection for solar farms, other factors such as proximity to existing electrical infrastructure, land use regulations, and environmental considerations would also need to be taken into account. Additionally, given the region's history of industrial activity, some areas may require environmental assessment before being repurposed for solar energy production.
