Marshall, Minnesota, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. This location experiences significant seasonal variations in solar potential, which impacts the overall effectiveness of solar PV systems.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Marshall, with an impressive output of 6.92 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, generating 5.31 kWh/day. However, the colder months see a substantial drop in solar production, with autumn yielding 3.41 kWh/day and winter producing only 2.33 kWh/day.

These figures indicate that Marshall experiences a significant solar energy potential during the warmer months, making it an attractive option for solar PV installation. The long summer days and generally clear skies contribute to this high productivity. Spring also offers good solar potential as daylight hours increase and temperatures rise.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Marshall, fixed solar panels should be installed at a tilt angle of 38 degrees facing south. This optimal angle takes into account the location's latitude and seasonal sun positions, ensuring the best possible exposure to sunlight throughout the year.

Environmental and Weather Considerations

While Marshall's location is generally favorable for solar energy production, there are some environmental and weather factors that could impact solar PV performance:

• Snow accumulation in winter can temporarily reduce panel efficiency
• Occasional severe weather events, such as hailstorms, may pose a risk to solar installations

To mitigate these factors, solar installations in Marshall should incorporate robust mounting systems capable of withstanding high winds and hail. Additionally, panels should be installed at an angle that facilitates snow shedding. Regular maintenance, including snow removal during winter months, can help ensure optimal performance year-round.

Despite the challenges posed by winter conditions, Marshall's location still offers considerable potential for solar energy generation, particularly during the spring and summer months. With proper installation and maintenance, solar PV systems can provide a significant contribution to the area's energy needs.

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 Marshall, Minnesota

Seasonal solar PV output for Latitude: 44.4491, Longitude: -95.7848 (Marshall, Minnesota, 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 38° South in Marshall, Minnesota, United States

To maximize your solar PV system's energy output in Marshall, Minnesota, United States (Lat/Long 44.4491, -95.7848) throughout the year, you should tilt your panels at an angle of 38° 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 Marshall, Minnesota, 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 Marshall, Minnesota, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	48° South in Autumn	58° South in Winter	37° 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 Marshall, Minnesota, 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 Marshall, Minnesota, 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 Marshall, Minnesota, United States

The topography around Marshall, Minnesota, located at 44.4491°N, 95.7848°W, is characterized by gently rolling plains typical of the Midwestern United States. This area is part of the vast Prairie Pothole Region, which was shaped by glacial activity during the last ice age. The landscape consists of mostly flat to slightly undulating terrain, with occasional shallow depressions known as potholes or sloughs that often contain wetlands or small ponds. The elevation in and around Marshall is relatively consistent, ranging from about 1,150 to 1,250 feet above sea level. The area is primarily agricultural, with expansive fields of crops such as corn and soybeans dominating the landscape. The Redwood River flows through Marshall, creating a shallow valley that adds some minor topographical variation to the otherwise level terrain.

Suitable Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Marshall, several factors come into play. The most suitable areas would be those that combine favorable topography with minimal environmental and land-use conflicts. The flat, open farmland surrounding Marshall presents numerous opportunities for solar development. Areas to the east and south of the city, where the terrain is particularly level and unobstructed, would be well-suited for large solar arrays. These locations offer expansive tracts of land with minimal shading from trees or structures, maximizing potential solar exposure throughout the day. Additionally, areas along major roads or near existing electrical infrastructure could be advantageous for solar PV development. This might include land adjacent to Highway 23 or Highway 59, which could facilitate easier connection to the power grid and simplify maintenance access. It's important to note that while the topography is generally favorable for solar development throughout the region, other factors such as land ownership, current agricultural use, and proximity to wildlife habitats would need to be carefully considered. Ideal sites would balance the need for open, sunny spaces with the preservation of prime farmland and sensitive ecosystems.
