Alpine, Utah, situated in the Northern Temperate Zone, offers a varied landscape for solar energy production throughout the year. The location experiences significant seasonal fluctuations in solar output, which can impact the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Summer stands out as the prime season for solar energy generation in Alpine, with an impressive daily output of 7.85 kWh per kW of installed solar capacity. Spring follows closely behind, yielding 6.70 kWh/day. These seasons provide ample sunlight and longer days, making them ideal for maximizing solar energy production.
Autumn sees a noticeable decline in solar output, dropping to 4.12 kWh/day. Winter presents the most challenging conditions for solar generation, with daily production falling to just 2.59 kWh per kW installed. This significant seasonal variation underscores the importance of proper system sizing to ensure adequate year-round energy supply.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Alpine, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This optimal angle helps balance energy capture across seasons, ensuring the best possible performance throughout the year.
Environmental and Weather Considerations
Alpine's location in Utah's mountainous region introduces some environmental factors that could affect solar production:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Potential for dust and pollen during dry seasons may impact panel performance
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and implement regular cleaning routines. Additionally, using high-quality, durable panels designed to withstand local weather conditions can help maintain optimal performance.
Despite these challenges, Alpine's location generally provides favorable conditions for solar energy production, especially during the spring and summer months. With proper installation and maintenance, a solar PV system in this area can effectively harness the abundant sunlight and contribute significantly to meeting local energy needs.
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 Alpine, Utah
Seasonal solar PV output for Latitude: 40.4599, Longitude: -111.7752 (Alpine, Utah, 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 Alpine, Utah, United States
To maximize your solar PV system's energy output in Alpine, Utah, United States (Lat/Long 40.4599, -111.7752) 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 Alpine, Utah, 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 Alpine, Utah, 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 |
|---|---|---|---|
| 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.

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 Alpine, Utah, United States
Alpine, United States, located at latitude 40.4599 and longitude -111.7752, is situated in a picturesque mountainous region characterized by diverse topography. The area surrounding Alpine is dominated by the impressive Wasatch Range, which forms part of the Rocky Mountains. This mountain range creates a dramatic backdrop for the city, with steep slopes and rugged peaks rising sharply from the valley floor. To the west of Alpine lies Utah Valley, a relatively flat expanse that contrasts with the mountainous terrain to the east. This valley, which includes Utah Lake, provides a more level landscape amidst the surrounding highlands. The transition between the valley and the mountains is marked by foothills and gentle slopes that gradually give way to more dramatic elevations.
Nearby Areas Suitable for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Alpine, the most suitable areas would likely be found in the more open, flatter regions to the west and southwest. The Utah Valley, with its expansive terrain and fewer obstructions, offers promising potential for solar energy development. Specifically, the areas surrounding Utah Lake, particularly to its west and south, could be well-suited for solar PV projects. These locations benefit from relatively level ground, which simplifies installation and maintenance of solar panels. Additionally, the open landscape in these areas receives ample sunlight throughout the day, maximizing potential energy generation. It's important to note that while the mountainous regions surrounding Alpine offer breathtaking views, they are generally less suitable for large-scale solar installations. The steep slopes, variable terrain, and potential shading from nearby peaks can reduce the efficiency and feasibility of solar projects in these areas. However, any large-scale solar development would need to consider factors beyond just topography, such as local zoning laws, environmental impact, and proximity to existing power infrastructure. Careful site selection and environmental assessments would be necessary to ensure the success and sustainability of any solar PV project in the region.United States solar PV Stats as a country
