Powell, Wyoming, located in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation. The location experiences significant seasonal variations in solar output, which affects its overall suitability for year-round solar energy production.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 7.29 kWh per day output for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.87 kWh per day. However, autumn and winter see a substantial drop in production, with 3.61 kWh and 2.09 kWh per day, respectively.

These figures indicate that Powell's solar potential is heavily skewed towards the warmer months. The long summer days and higher sun angle during this period make it an ideal time for solar energy generation. Spring also offers good potential, with increasing daylight hours and moderate temperatures.

Optimizing Solar Panel Installation

To maximize year-round solar production in Powell, fixed solar panels should be tilted at a 38-degree angle facing south. This optimal angle takes into account the location's latitude and seasonal sun positions, ensuring the best possible exposure throughout the year.

Environmental and Weather Considerations

While Powell's location is generally favorable for solar energy, there are some environmental factors to consider:

• Snow accumulation in winter can significantly reduce solar panel efficiency. Regular panel cleaning or installing panels at a steeper angle can help mitigate this issue.
• Dust and pollen from agricultural activities in the region may accumulate on panels, especially during dry periods. Implementing a routine cleaning schedule can maintain optimal performance.

Despite these challenges, with proper installation and maintenance, solar PV systems in Powell can be an effective source of renewable energy, particularly during the spring and summer months. The substantial difference between summer and winter output suggests that supplementary energy sources or storage solutions might be necessary for year-round reliability.

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 Powell, Wyoming

Seasonal solar PV output for Latitude: 44.7538, Longitude: -108.7574 (Powell, Wyoming, 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 38° South in Powell, Wyoming, United States

To maximize your solar PV system's energy output in Powell, Wyoming, United States (Lat/Long 44.7538, -108.7574) throughout the year, you should tilt your panels at an angle of 38° 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 Powell, Wyoming, 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 Powell, Wyoming, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	48° South in Autumn	59° South in Winter	37° 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 Powell, Wyoming, 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 Powell, Wyoming, 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 Powell, Wyoming, United States

The topography around Powell, Wyoming in the United States is characterized by a diverse landscape typical of the American West. Located in the Bighorn Basin, Powell is surrounded by relatively flat to gently rolling terrain. The area is part of a large intermontane basin, which means it's a lowland area nestled between mountain ranges. To the east of Powell, the land gradually rises towards the Bighorn Mountains, creating a picturesque backdrop to the region. These mountains, while not immediately adjacent to Powell, are visible from the area and contribute to the scenic beauty of the landscape. To the west, the terrain becomes more rugged as it approaches the Absaroka Range, part of the Rocky Mountains. The immediate vicinity of Powell features agricultural lands, with many irrigated fields creating a patchwork of green amidst the semi-arid environment. The Shoshone River flows to the south of Powell, carving a shallow valley through the landscape and providing water for irrigation.

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 relatively flat terrain surrounding Powell offers promising locations for solar farms. The open, unobstructed land to the north and east of the town would be particularly well-suited for such developments. These areas benefit from minimal shading from geographical features, allowing for maximum sun exposure throughout the day. The gentle slopes in some locations could even be advantageous, as they can be oriented to optimize solar panel placement for increased efficiency. Moreover, the semi-arid climate of the region means there are many clear, sunny days throughout the year, which is ideal for solar energy production. The lack of dense vegetation or forests in the immediate surroundings also reduces potential obstacles for large-scale installations. However, it's important to note that any specific site selection would require detailed environmental and grid connectivity assessments. The proximity to existing power infrastructure and the impact on local ecosystems and agricultural land would need to be carefully evaluated before proceeding with any large-scale solar PV projects in the area.
