Frederick, Colorado in the United States offers a variable solar energy potential throughout the year, with significant seasonal differences in electricity generation. Located in the Northern Temperate Zone, this location experiences distinct seasons that directly impact solar PV performance.

Seasonal Solar Production

Summer stands out as the most productive season in Frederick, with solar panels generating approximately 7.48kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, yielding about 5.79kWh/day per kW. Autumn production drops to 4.50kWh/day per kW, while winter shows the lowest output at just 2.85kWh/day per kW.

This seasonal pattern creates a nearly threefold difference between peak summer and minimum winter production, which is typical for locations in the Northern Temperate Zone. The substantial drop during winter months means that system sizing needs to account for these seasonal variations if year-round energy needs are to be met.

Optimal Panel Installation

For fixed solar panel installations in Frederick, the ideal tilt angle to maximize year-round energy production is 35 degrees facing South. This angle represents the mathematically optimized position that balances seasonal solar elevation changes throughout the year, weighted by the available solar energy at this specific location.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Frederick. Colorado's Front Range region is known for occasional hailstorms during spring and summer months, which can damage solar panels if severe enough. Installing impact-resistant panels or panels with hail certification can mitigate this risk.

Winter snowfall can temporarily reduce production by covering panels. This can be addressed by installing panels at the recommended 35-degree tilt, which helps snow slide off more easily than flatter installations. Some systems may benefit from occasional snow removal during heavy accumulation periods.

The area also experiences periodic dust storms and high winds, which can deposit dirt on panel surfaces and reduce efficiency. Regular cleaning and maintenance can help counter this issue. Additionally, choosing mounting systems rated for local wind conditions is important for system longevity.

Frederick's generally sunny climate with relatively low humidity is otherwise quite favorable for solar production, with few other significant impediments to solar generation throughout the year.

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 Frederick, Colorado

Seasonal solar PV output for Latitude: 40.095, Longitude: -104.9378 (Frederick, 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 35° South in Frederick, Colorado, United States

To maximize your solar PV system's energy output in Frederick, Colorado, United States (Lat/Long 40.095, -104.9378) throughout the year, you should tilt your panels at an angle of 35° 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 Frederick, 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 Frederick, Colorado, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° 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.

Calculate solar panel row spacing in Frederick, 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 Frederick, Colorado, 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 Frederick, Colorado, United States

The landscape surrounding Frederick, Colorado unfolds as a captivating transition zone between the Great Plains and the foothills of the Rocky Mountains. Situated in Weld County in the northern part of the state, Frederick occupies an area characterized by gently rolling prairie terrain. The elevation sits at approximately 5,000 feet above sea level, creating a high plains environment that gradually rises toward the west where the majestic Front Range of the Rocky Mountains dominates the horizon. The topography around Frederick primarily consists of open grasslands and agricultural fields stretching across a relatively flat to moderately undulating surface. This area forms part of the Colorado Piedmont, a region where the High Plains meet the Rocky Mountain foothills. Small creeks and drainage systems carve subtle valleys through the landscape, including the nearby St. Vrain Creek and Boulder Creek watersheds that eventually feed into the South Platte River system.

Soil and Surface Features

The soils around Frederick typically consist of fertile loams and clay loams that have supported agricultural activities for generations. The natural vegetation, where undisturbed, includes native prairie grasses and scattered shrubs adapted to the semi-arid climate. The terrain lacks significant forested areas except along watercourses where cottonwoods and other riparian vegetation may form narrow corridors. Unlike the dramatic mountain landscapes to the west, the Frederick area features more subtle topographic variations. Small buttes, gentle hills, and shallow drainages provide minor relief to the predominantly level landscape. This relatively flat character makes much of the surrounding land accessible for various land uses, from farming to potential energy development.

Solar Potential Areas

The areas most suitable for large-scale solar photovoltaic development near Frederick would be the extensive tracts of level to gently sloping land, particularly in the eastern and northeastern directions where the terrain becomes increasingly flat as it extends into the High Plains proper. These locations offer several advantages for solar installations: The flat to gently rolling terrain minimizes the need for extensive grading and site preparation, reducing construction costs and environmental disruption. Additionally, the open character of the landscape means fewer natural obstacles that might cast shadows across solar arrays, maximizing potential energy capture throughout the day. Land parcels east of Frederick, extending toward the communities of Firestone and Dacono, present particularly favorable conditions. These areas combine accessible terrain with proximity to existing electrical infrastructure, including transmission lines that connect to the greater Denver metropolitan area's power grid. The northern sectors toward Mead and the eastern reaches toward Fort Lupton also contain significant tracts of suitable land. These regions feature expansive, open spaces with minimal topographic constraints and good solar exposure. The consistent grade and lack of significant drainage issues in many of these areas further enhance their suitability for large-scale installations.

Topographic Considerations

While seeking optimal sites for solar development, several topographic factors merit consideration. The subtle slopes facing south and southeast generally receive more direct sunlight in the northern hemisphere, potentially increasing energy production efficiency. Areas with minimal shadowing from landforms, even the distant mountain silhouettes to the west, would maintain consistent energy generation throughout the day. The region experiences relatively low precipitation, limiting concerns about erosion or drainage issues that might affect solar infrastructure. However, site-specific assessments would still be necessary to identify any localized drainage patterns or seasonal water accumulation areas that could impact facility design or operation. The combination of favorable topography, abundant open space, and proximity to energy infrastructure makes the Frederick area a compelling candidate for solar energy development, with the eastern plains offering particularly advantageous conditions for large-scale photovoltaic installations.
