Durango, Colorado, located in the Northern Temperate Zone, offers a relatively favorable location for solar PV energy generation throughout the year. With its geographical coordinates at 37.2845° N latitude and 107.8646° W longitude, Durango experiences varying levels of solar energy potential across different seasons.
Seasonal Solar Energy Production
Solar energy production in Durango fluctuates significantly between seasons. Summer stands out as the most productive period, with an impressive 7.25 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 6.71 kWh/day/kW. Autumn sees a moderate decrease in production at 4.80 kWh/day/kW, while winter experiences the lowest output at 3.34 kWh/day/kW.
The substantial difference between summer and winter production highlights the impact of seasonal variations on solar energy generation in Durango. However, the relatively high output during spring and autumn suggests that solar PV systems can still be effective for a significant portion of the year.
Optimal Panel Tilt Angle
For fixed panel installations in Durango, the ideal tilt angle to maximize year-round solar production is 33 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and Durango's specific latitude.
Environmental and Weather Considerations
While Durango's location is generally favorable for solar energy production, there are some environmental and weather factors to consider:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Occasional dust storms may deposit debris on panels, affecting performance
To mitigate these issues, installing panels at the recommended 33-degree tilt can help shed snow more easily. Regular cleaning and maintenance of panels, especially after dust storms, can ensure optimal performance. Additionally, considering snow-resistant panel designs and incorporating automated cleaning systems can further enhance energy production in challenging conditions.
Overall, Durango's location provides a good balance of solar potential throughout the year, with summer and spring offering excellent opportunities for energy generation. While winter production is lower, the area's generally sunny climate makes it a suitable location for solar PV systems with proper installation and maintenance practices.

Seasonal solar PV output for Latitude: 37.2845, Longitude: -107.8646 (Durango, 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 Durango, United States
To maximize your solar PV system's energy output in Durango, United States (Lat/Long 37.2845, -107.8646) 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 Durango, 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 Durango, 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 Durango, 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 Durango, 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 Durango, United States
The topography around Durango, Colorado, is characterized by a diverse and rugged landscape typical of the southwestern United States. Situated in the Animas River Valley, Durango is surrounded by the impressive San Juan Mountains, which are part of the larger Rocky Mountain range. The city itself sits at an elevation of approximately 6,512 feet (1,985 meters) above sea level, with the surrounding terrain featuring a mix of steep mountain slopes, mesas, and valleys. To the north and east of Durango, the landscape is dominated by the San Juan Mountains, with peaks reaching elevations over 14,000 feet (4,267 meters). These mountains create a dramatic backdrop and offer numerous opportunities for outdoor recreation. The terrain in this direction is characterized by steep, forested slopes, rocky outcrops, and high-altitude meadows. To the south and west, the landscape transitions into a series of mesas and canyons. This area is part of the Colorado Plateau, featuring flat-topped hills and deep, carved valleys. The terrain becomes increasingly arid as you move away from the mountains, with vegetation transitioning from dense forests to more sparse, desert-like flora.
Potential Areas for Large-Scale Solar PV
When considering areas near Durango for large-scale solar photovoltaic (PV) installations, several factors come into play, including topography, sun exposure, and land availability. The most suitable locations for solar PV projects would likely be found to the south and west of Durango, where the terrain becomes flatter and more open. The mesa tops and gently sloping areas of the Colorado Plateau offer ideal conditions for solar installations. These locations typically receive ample sunlight throughout the year and have fewer obstructions that could cast shadows on solar panels. The relatively flat terrain of the mesas also makes construction and maintenance of solar facilities more straightforward and cost-effective. Specific areas that might be well-suited for large-scale solar PV projects include the expanses south of Durango towards the New Mexico border, and the areas west of the city towards Cortez and Dolores. These regions generally have lower population densities and more available land that could potentially be developed for solar energy production. It's important to note that while these areas may be topographically suitable, any large-scale solar development would need to consider other factors such as proximity to existing power infrastructure, environmental impact, and local zoning regulations. Additionally, care should be taken to balance energy development with the preservation of the region's natural beauty and ecological integrity, which are vital to the area's tourism and outdoor recreation industries.United States solar PV Stats as a country
