Solar PV Analysis of Alamosa, United States
Alamosa, Colorado, situated in the Northern Temperate Zone at coordinates 37.4725, -105.8796, presents a relatively favorable location for solar PV energy generation throughout the year. The area experiences distinct seasonal variations in solar output, which can significantly impact the efficiency of photovoltaic systems.
Seasonal Solar Performance
Summer stands out as the peak season for solar energy production in Alamosa, with an impressive average of 7.72 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 6.79 kWh/day. Autumn sees a moderate decrease to 5.10 kWh/day, while winter experiences the lowest output at 3.80 kWh/day.
These figures indicate that Alamosa benefits from strong solar potential during the warmer months, particularly from late spring through early fall. The extended daylight hours and typically clear skies during this period contribute to optimal energy generation.
Optimal Panel Installation
To maximize year-round solar production in Alamosa, fixed solar panels should be installed at a tilt angle of 33 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.
Environmental Considerations
While Alamosa offers generally favorable conditions for solar energy production, there are some environmental factors to consider:
- Snow accumulation: Alamosa experiences snowfall during winter months, which can temporarily reduce panel efficiency. Installing panels at the recommended angle helps with natural snow shedding.
- Dust and pollen: The region's semi-arid climate can lead to dust accumulation on panels. Regular cleaning and maintenance can mitigate this issue.
To address these factors, consider implementing snow guards to prevent sudden snow slides, and schedule periodic panel cleaning, especially after dust storms or during pollen season. Additionally, investing in high-quality, durable panels designed to withstand local weather conditions can enhance long-term performance and reliability.
Overall, Alamosa's climate and geographic location make it a suitable candidate for solar PV installations, with the potential for significant energy production, particularly during the spring and summer months.

Solar output per kW of installed solar PV by season in Alamosa
Seasonal solar PV output for Latitude: 37.4725, Longitude: -105.8796 (Alamosa, 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 33° South in Alamosa, United States
To maximize your solar PV system's energy output in Alamosa, United States (Lat/Long 37.4725, -105.8796) throughout the year, you should tilt your panels at an angle of 33° 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 Alamosa, 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 Alamosa, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° South in Summer | 42° South in Autumn | 52° South in Winter | 30° 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 Alamosa, 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 Alamosa, 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 Alamosa, United States
The topography around Alamosa, Colorado, is characterized by a unique and diverse landscape. Alamosa is situated in the San Luis Valley, which is a vast, high-altitude basin surrounded by impressive mountain ranges. This area is known for its relatively flat valley floor, which sits at an elevation of about 7,500 feet above sea level.
To the east and west of Alamosa, the terrain rises dramatically into the Sangre de Cristo Mountains and the San Juan Mountains, respectively. These mountain ranges create a stunning backdrop to the otherwise level valley floor. The valley itself is quite expansive, stretching approximately 125 miles from north to south and about 65 miles from east to west.
The immediate vicinity of Alamosa features a mix of agricultural lands, grasslands, and wetlands. The Rio Grande River flows through the area, creating a riparian ecosystem that contrasts with the drier surrounding landscape. Sand dunes can also be found to the northeast of Alamosa, forming part of the Great Sand Dunes National Park and Preserve.
Regarding areas suitable for large-scale solar PV installations, the San Luis Valley presents excellent opportunities. The valley's flat terrain, high elevation, and abundance of sunny days make it an ideal location for solar energy production. Specifically, the open areas to the north and south of Alamosa would be well-suited for such projects.
These locations offer several advantages for solar PV development:
- Minimal topographical obstacles, allowing for easy installation and maintenance of solar panels
- Reduced shading from mountains due to the wide-open nature of the valley
- High altitude, which means clearer air and more intense sunlight
- Low population density, providing ample space for large installations
- Proximity to existing power infrastructure in and around Alamosa
It's worth noting that while these areas are well-suited for solar PV, any large-scale development would need to consider environmental impacts, land use regulations, and the needs of local communities and agriculture. The region's water scarcity and fragile ecosystem would also need to be taken into account when planning such projects.
