Gardner, Colorado in the United States offers a promising location for solar PV energy generation, with varying seasonal performance throughout the year. Located in the Northern Temperate Zone, this site experiences significant seasonal fluctuations in solar energy production that follow predictable patterns.
Seasonal Solar Production
The solar energy potential at Gardner shows strong seasonal variation. Summer stands out as the most productive season, generating approximately 7.72kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.76kWh/day. Autumn production drops to 5.05kWh/day, while winter represents the lowest output period with 3.73kWh/day per installed kilowatt.
This seasonal pattern means that a solar installation in Gardner will produce more than twice as much electricity in summer compared to winter months, making summer and spring the ideal times for solar energy generation at this location.
Optimal Panel Installation
For fixed solar panel installations in Gardner, the ideal tilt angle to maximize year-round energy production is 34 degrees facing South. This carefully calculated angle optimizes the annual solar harvest by balancing seasonal variations in sun position and intensity throughout the year.
Environmental Considerations
Several environmental factors could potentially affect solar production at this location:
- Snow accumulation during winter months may temporarily reduce panel output unless properly managed
- Dust and pollen can accumulate on panels, particularly during dry periods
- Possible shading from nearby mountains, given Colorado's topography
To mitigate these challenges, solar installations in Gardner would benefit from regular cleaning schedules, snow removal systems (or steeper winter tilt angles), and careful site assessment to avoid mountain shadow effects. Additionally, installing microinverters or power optimizers can help minimize production losses when partial shading occurs.
Despite these considerations, Gardner's position in the Northern Temperate Zone with strong summer and spring production makes it a viable location for solar PV generation, particularly if installations are optimized with the recommended 34-degree south-facing tilt.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Gardner, Colorado
Seasonal solar PV output for Latitude: 37.7833, Longitude: -105.1655 (Gardner, Colorado, 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 Gardner, Colorado, United States
To maximize your solar PV system's energy output in Gardner, Colorado, United States (Lat/Long 37.7833, -105.1655) 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 Gardner, Colorado, 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 Gardner, Colorado, 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 |
|---|---|---|---|
| 22° South in Summer | 42° South in Autumn | 53° South in Winter | 31° 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 Gardner, Colorado, 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 Gardner, Colorado, 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 Gardner, Colorado, United States
Topography of Gardner, Colorado
Gardner is nestled in a picturesque region of southern Colorado, situated at the western edge of the Huerfano Valley. The area around Gardner exhibits diverse topographical features characterized by a transition zone between the eastern plains and the majestic Sangre de Cristo Mountains to the west. The immediate vicinity has an elevation of approximately 7,000 feet above sea level, placing it in the foothills region of Colorado. The landscape surrounding Gardner displays a mixture of gently rolling hills, grassy meadows, and steeper terrain as one moves westward toward the mountains. The Huerfano River runs through this area, having carved valleys and creating riparian corridors amid the predominantly semi-arid environment. To the east, the terrain gradually flattens as it extends toward the Great Plains, while to the west, the landscape rises dramatically into the Sangre de Cristo range, with peaks exceeding 14,000 feet.Ideal Areas for Solar PV Development
Several factors make certain areas around Gardner particularly suitable for large-scale solar photovoltaic installations. The most promising locations for solar development near Gardner would be the gently sloping, south-facing areas to the east and southeast of the community. These areas combine favorable topographical characteristics with optimal solar exposure conditions. The relatively flat to gently rolling terrain east of Gardner, extending toward the Huerfano Valley, presents ideal conditions for large-scale solar installations. These areas offer sufficient space for extensive arrays while requiring minimal grading work. The gradual slopes in these regions also provide natural drainage, reducing potential erosion concerns that might otherwise impact solar infrastructure. Another promising region lies in the elevated bench lands and mesas that occur throughout the area. These elevated plateaus typically have minimal vegetation obstruction and excellent southern exposure. The higher elevation also means these areas experience less fog and atmospheric interference that might otherwise reduce solar efficiency. The areas immediately west of Gardner become less suitable for large-scale solar development as the terrain quickly transitions to the steeper foothills and eventually mountains. These western zones present challenges including difficult access, shadowing effects from the mountains during certain periods, and increased construction complexity due to the rugged terrain. From a practical development perspective, locations with proximity to existing transmission infrastructure would be particularly advantageous. The relatively open valleys and flatlands that follow major transportation corridors in the region often combine favorable topography with easier access to the electrical grid, making them prime candidates for solar development. The semi-arid climate of this region means that much of the land features sparse vegetation dominated by drought-resistant species, which minimizes the environmental impact of converting these areas to solar use compared to more densely vegetated regions elsewhere in Colorado.United States solar PV Stats as a country
