Park City, Utah, located in the United States, offers a mixed landscape for solar energy generation throughout the year. This location, situated in the Northern Temperate Zone, experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Park City, with an impressive daily output of 7.85 kWh per kW of installed solar capacity. Spring follows closely behind, generating 6.70 kWh/day. However, the colder months see a substantial drop in production, with autumn yielding 4.12 kWh/day and winter plummeting to a mere 2.59 kWh/day.

This stark contrast between seasons indicates that Park City is particularly well-suited for solar energy generation during the warmer months, from late spring through early fall. During this period, longer days and higher sun angles contribute to enhanced solar panel efficiency.

Optimal Panel Positioning

To maximize year-round solar production in Park City, fixed solar panels should be tilted at a 35-degree angle facing south. This optimal angle takes into account the location's latitude and seasonal sun paths, striking a balance between summer and winter performance.

Environmental Considerations

While Park City boasts excellent solar potential, there are some environmental factors that could impact solar production:

• Snowfall: Park City receives significant snowfall during winter months, which can temporarily cover solar panels and reduce efficiency.
• Mountain shadows: The surrounding mountainous terrain may cast shadows on solar installations, particularly during early morning and late afternoon hours.

To mitigate these challenges, solar installers can implement several strategies. For snow accumulation, panels can be installed at a steeper angle to promote snow sliding off. Additionally, regular maintenance and snow removal may be necessary during heavy snowfall periods. To address mountain shadows, careful site selection and panel orientation become crucial, potentially utilizing sun-tracking systems in some cases to maximize exposure.

Despite these challenges, Park City's location still offers substantial solar energy potential, especially when leveraging the peak production periods during summer and spring. With proper planning and installation techniques, solar PV systems can provide a significant contribution to the area's renewable energy portfolio.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Park City

Seasonal solar PV output for Latitude: 40.7038, Longitude: -111.5437 (Park City, 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 Park City, United States

To maximize your solar PV system's energy output in Park City, United States (Lat/Long 40.7038, -111.5437) 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 Park City, 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 Park City, 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 Park City, 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 Park City, 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 Park City, United States

Park City, located in Utah, is nestled in a picturesque mountainous region known as the Wasatch Back. The topography surrounding this popular resort town is characterized by dramatic elevation changes and diverse terrain. The area features steep, forested mountains interspersed with valleys and canyons, creating a stunning landscape that attracts visitors year-round. The city itself sits at an elevation of approximately 7,000 feet above sea level, with nearby peaks reaching heights of over 10,000 feet. The surrounding mountains are part of the Wasatch Range, which runs north-south through Utah. These mountains are typically covered in dense forests of pine, aspen, and other coniferous trees, with some areas giving way to open meadows and rocky outcrops. To the west of Park City, the terrain gradually descends towards the Salt Lake Valley, where the topography becomes flatter and more suitable for urban development. East of the city, the landscape remains mountainous, with rolling hills and valleys extending into the Uinta Mountains.

Potential Areas for Large-Scale Solar PV

When considering areas near Park City for large-scale solar photovoltaic (PV) installations, it's important to look for relatively flat, open spaces with good sun exposure. While the mountainous terrain immediately surrounding Park City may not be ideal for such projects, there are several areas within a reasonable distance that could be more suitable: The Salt Lake Valley, located to the west of Park City, offers more expansive, flat terrain that could accommodate large solar arrays. This area receives ample sunlight and has fewer geographical obstacles that might obstruct solar panels. South of Park City, towards the Heber Valley, there are open areas with gentler slopes that could potentially be used for solar installations. These locations benefit from the high elevation, which can increase solar efficiency due to less atmospheric interference. To the north and east, in the direction of Coalville and Kamas, there are some valley areas with open land that might be suitable for solar projects. These locations would need to be carefully evaluated to ensure they receive sufficient sunlight throughout the year, as surrounding mountains could potentially cast shadows during certain times of the day or season. It's worth noting that while these areas may be topographically suitable for large-scale solar PV, other factors such as land ownership, environmental considerations, and proximity to power infrastructure would also need to be taken into account when planning any significant solar energy development near Park City.
