Solar PV Analysis of Cranberry Township, United States
Cranberry Township, Pennsylvania, located in the Northern Temperate Zone, offers a moderate potential for solar energy generation throughout the year. The location's solar productivity varies significantly across seasons, with summer being the most productive period and winter the least.
Seasonal Solar Performance
Solar panels in Cranberry Township can expect to generate an average of 6.10 kWh per day for each kW of installed capacity during summer. This output drops to 3.46 kWh/day in autumn and plummets to just 1.84 kWh/day in winter. Spring sees a significant rebound, with daily production reaching 5.37 kWh/day per kW installed.
The substantial variation between seasons indicates that while solar energy can be a viable option in this location, it may require careful planning and potentially supplementary energy sources during the less productive winter months.
Optimal Panel Placement
To maximize year-round solar production in Cranberry Township, fixed solar panels should be installed at a tilt angle of 35 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.
Environmental and Weather Considerations
Several factors could potentially impact solar production in Cranberry Township:
- Snow accumulation in winter can significantly reduce panel efficiency.
- Frequent cloud cover, especially during winter months, may limit solar exposure.
- Tree cover and shading from nearby structures could obstruct sunlight.
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off, using snow removal techniques when necessary, and ensuring panels are placed in areas with minimal shading throughout the day. Additionally, using high-efficiency panels and incorporating a battery storage system can help maximize energy capture during peak production periods and provide power during less productive times.
In conclusion, while Cranberry Township's location presents some challenges for year-round solar energy production, proper planning and installation techniques can still make solar a viable renewable energy option for residents and businesses in the area.

Solar output per kW of installed solar PV by season in Cranberry Township
Seasonal solar PV output for Latitude: 40.6956, Longitude: -80.0969 (Cranberry Township, 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 Cranberry Township, United States
To maximize your solar PV system's energy output in Cranberry Township, United States (Lat/Long 40.6956, -80.0969) 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 Cranberry Township, 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 Cranberry Township, 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 | 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 Cranberry Township, 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 Cranberry Township, 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 Cranberry Township, United States
The topography around Cranberry Township, located in western Pennsylvania, is characterized by gently rolling hills and shallow valleys. This area is part of the Allegheny Plateau, which is a physiographic region known for its moderate elevation changes and undulating landscape. The terrain is not particularly steep or mountainous, but rather consists of a series of low hills and broad ridges interspersed with small streams and creeks.
The elevation in Cranberry Township and its surrounding areas typically ranges from about 900 to 1,300 feet above sea level. This variation in elevation creates a patchwork of slopes and flat areas throughout the region. The landscape is also marked by numerous small waterways, including Brush Creek and its tributaries, which have carved shallow valleys into the terrain over time.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. Ideally, solar farms require relatively flat or gently sloping land with good exposure to sunlight throughout the day. Based on the topography of the region around Cranberry Township, some potentially suitable areas might include:
- Open agricultural fields: The surrounding rural areas often feature expansive farmlands with minimal slope, which could be repurposed for solar installations.
- Plateau tops: The flatter areas atop some of the broader hills or ridges in the region could provide suitable sites for solar arrays.
- Reclaimed mining sites: Western Pennsylvania has a history of coal mining, and some nearby reclaimed mine lands might offer large, open spaces ideal for solar development.
- Industrial parks or brownfields: Existing industrial areas or abandoned industrial sites in the vicinity could be repurposed for solar energy production.
It's important to note that while the topography in this region is generally favorable for solar PV installations, other factors such as local zoning regulations, grid connectivity, and environmental considerations would also need to be taken into account when determining the most suitable locations for large-scale solar projects.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
