Cloquet, Minnesota, located in the Northern Temperate Zone, presents a mixed picture for year-round solar energy generation. The city experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems throughout the year.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Cloquet, with an impressive daily output of 6.68 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.19 kWh/day. However, the performance drops considerably during autumn and winter, with outputs of 3.07 kWh/day and 2.11 kWh/day, respectively.

These figures indicate that solar energy production in Cloquet is most effective from late spring through early fall. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.

Optimal Panel Installation

To maximize year-round solar energy production in Cloquet, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental and Weather Factors

Several factors can impede solar production in Cloquet:

1. Snow accumulation in winter
2. Cloud cover, particularly during autumn and winter
3. Short daylight hours in winter

To mitigate these challenges, consider the following preventative measures:

• Install panels at a steeper angle to promote snow sliding off
• Use snow-clearing tools or heating elements for panels
• Implement a robust cleaning schedule to maintain panel efficiency
• Consider using high-efficiency panels to maximize output during low-light conditions

While Cloquet's location presents some challenges for year-round solar energy production, proper system design and maintenance can help maximize the benefits of solar PV technology in this northern climate.

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 Cloquet

Seasonal solar PV output for Latitude: 46.7216, Longitude: -92.4594 (Cloquet, 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 40° South in Cloquet, United States

To maximize your solar PV system's energy output in Cloquet, United States (Lat/Long 46.7216, -92.4594) throughout the year, you should tilt your panels at an angle of 40° 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 Cloquet, 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 Cloquet, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
30° South in Summer	50° South in Autumn	60° South in Winter	39° 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 Cloquet, 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 Cloquet, 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 Cloquet, United States

The topography around Cloquet, Minnesota, located at 46.7216°N and 92.4594°W, is characterized by a mix of gently rolling hills, flat plains, and forested areas. This region, situated in northeastern Minnesota, is part of the larger Great Lakes Plains physiographic province. The landscape has been shaped by glacial activity during the last ice age, resulting in a diverse terrain with numerous lakes, rivers, and wetlands. The area surrounding Cloquet features elevations ranging from approximately 1,000 to 1,300 feet above sea level. The St. Louis River, which flows through Cloquet, has carved a shallow valley in the landscape, creating some localized variations in elevation. The region is dotted with small lakes and ponds, remnants of glacial activity, which contribute to the area's scenic beauty and ecological diversity.

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 ideal locations for solar farms in this region would be: Open, flat areas: The relatively flat plains to the south and west of Cloquet offer potential sites for solar installations. These areas typically have fewer obstructions that could cast shadows on solar panels, maximizing sunlight exposure throughout the day. Former agricultural lands: Abandoned or underutilized farmland in the surrounding rural areas could be repurposed for solar energy production. These sites often have the advantage of being already cleared and having existing access roads. Areas with minimal tree cover: While much of the region is forested, there are pockets of land with less dense tree cover. These areas would require less clearing and have a lower environmental impact when developed for solar energy. South-facing slopes: Gently sloping hillsides that face south would be particularly advantageous for solar PV installations, as they naturally maximize exposure to sunlight throughout the day. It's important to note that while the topography around Cloquet is generally suitable for solar energy development, the region's northern latitude and cloudy climate may impact overall solar potential. Additionally, any large-scale solar project would need to consider factors such as proximity to existing electrical infrastructure, local zoning regulations, and environmental impact assessments.
