Uniontown, Pennsylvania, located in the Northern Temperate Zone at latitude 39.9001 and longitude -79.7164, presents a moderate opportunity for solar energy generation throughout the year. The location experiences significant seasonal variations in solar energy production, which is typical for regions at this latitude.

Seasonal Solar Energy Production

Solar energy production in Uniontown varies considerably across the seasons. Summer is the most productive period, with an average daily output of 6.26 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 5.27 kWh/day. Autumn sees a decline in production to 3.62 kWh/day, while winter experiences the lowest output at 1.98 kWh/day.

Optimal Times for Solar Generation

The most ideal time for solar energy production in Uniontown is from late spring through early fall. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The summer months of June, July, and August are particularly favorable, offering peak production potential.

Panel Installation Considerations

For fixed panel installations in Uniontown, the optimal tilt angle to maximize year-round solar production is 34 degrees facing south. This angle helps balance energy capture across seasons, accounting for the sun's changing position throughout the year.

Environmental and Weather Factors

Several environmental and weather factors can impact solar energy production in Uniontown:

1. Snow accumulation in winter can temporarily reduce panel efficiency
2. Cloudy days, which are common in the region, can decrease daily output

To mitigate these factors, consider installing panels at a steeper angle to promote snow sliding off and using high-efficiency panels that perform better in low-light conditions. Regular panel cleaning and maintenance can also help maintain optimal performance.

Conclusion

While Uniontown's location is not ideal for year-round solar energy production due to significant seasonal variations, it still offers good potential, especially during summer and spring. With proper installation techniques and maintenance, solar PV systems can be a viable renewable energy option for this area.

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

Seasonal solar PV output for Latitude: 39.9001, Longitude: -79.7164 (Uniontown, 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 34° South in Uniontown, Pennsylvania, United States

To maximize your solar PV system's energy output in Uniontown, Pennsylvania, United States (Lat/Long 39.9001, -79.7164) throughout the year, you should tilt your panels at an angle of 34° 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 Uniontown, 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 Uniontown, Pennsylvania, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
23° 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 Uniontown, 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 Uniontown, 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 Uniontown, Pennsylvania, United States

The area around Uniontown, Pennsylvania, located at 39.9001°N latitude and 79.7164°W longitude, is characterized by a diverse and picturesque topography typical of the Appalachian region. This part of southwestern Pennsylvania features rolling hills, gentle valleys, and occasional steep ridges, creating a landscape that is both beautiful and varied. The terrain surrounding Uniontown is part of the Allegheny Plateau, which has been shaped over millions of years by erosion and glacial activity. The result is a series of undulating hills interspersed with stream-carved valleys. The elevation in this area generally ranges from about 900 to 1,500 feet above sea level, with some higher points reaching up to 2,000 feet. To the east of Uniontown, the land becomes more rugged as it approaches the Laurel Highlands, a scenic region known for its higher elevations and forested slopes. This area includes Chestnut Ridge, a prominent geological feature that runs north-south and forms part of the westernmost ridge of the Appalachian Mountains.

Potential 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. The ideal locations for solar farms typically include flat or gently sloping land with good sun exposure and minimal shading from trees or other obstructions. In the vicinity of Uniontown, the most promising areas for solar PV development would likely be found in the broader valleys and on the tops of some of the less steep hills. These locations often provide larger, open spaces that could accommodate extensive arrays of solar panels. Specifically, the agricultural lands to the west and northwest of Uniontown, stretching towards Pittsburgh, might offer suitable sites. These areas tend to have more expansive, flatter terrain that has already been cleared for farming, potentially making it easier to repurpose for solar energy production. Additionally, some of the reclaimed strip mining sites in the region could be considered for solar development. These areas often provide large, open spaces with minimal vegetation and good sun exposure. However, careful site assessment would be necessary to ensure soil stability and environmental suitability. It's important to note that while the topography around Uniontown presents some challenges for large-scale solar installations due to its hilly nature, advancements in solar technology have made it increasingly feasible to utilize varied terrain for solar energy production. Careful site selection, combined with modern solar panel mounting systems, can help overcome some of the limitations posed by the region's topography.

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.
