Marinette, Wisconsin presents a moderately challenging location for year-round solar energy generation, with significant seasonal variations that are typical of northern temperate climates.

Seasonal Solar Production Patterns

The solar energy output at this location shows dramatic seasonal swings. Summer production peaks at 6.47 kWh per day per kilowatt of installed capacity, making it an excellent time for solar generation. Spring also offers strong performance at 5.02 kWh per day, providing good energy yields during this season. However, the colder months present significant challenges. Autumn production drops to 2.95 kWh per day, while winter sees the lowest output at just 1.72 kWh per day per kilowatt installed. This represents a nearly four-fold difference between peak summer and winter production.

Optimal Panel Configuration

For maximum year-round energy production at Marinette, solar panels should be installed at a fixed tilt angle of 38 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's changing position throughout the year and weighting for the varying solar potential across different seasons.

Environmental and Weather Challenges

Several significant local factors can impede solar production in this northern Wisconsin location:

• Heavy snow accumulation during winter months that can completely cover panels
• Ice formation that creates thick barriers blocking sunlight
• Frequent cloud cover and overcast conditions typical of Great Lakes region weather patterns
• Cold temperatures that can affect equipment performance and create thermal stress

Preventative Measures for Better Performance

To maximize solar energy production despite these challenges, several installation strategies should be considered:

• Install panels at steeper angles (potentially beyond the optimal 38 degrees) to encourage snow and ice to slide off naturally
• Use mounting systems that allow for easier manual snow removal when necessary
• Select cold-weather rated equipment designed to perform efficiently in sub-zero temperatures
• Consider micro-inverters or power optimizers to minimize the impact when individual panels are partially shaded or snow-covered
• Ensure adequate spacing between panel rows to reduce shading from accumulated snow

Despite these seasonal challenges, Marinette can still be viable for solar installations, particularly when systems are designed with winter conditions in mind and when the strong summer and spring production periods are factored into the overall energy planning strategy.

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 Marinette

Seasonal solar PV output for Latitude: 45.1, Longitude: -87.6307 (Marinette, 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 Marinette, United States

To maximize your solar PV system's energy output in Marinette, United States (Lat/Long 45.1, -87.6307) 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 Marinette, 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 Marinette, 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
29° South in Summer	49° South in Autumn	59° South in Winter	38° 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 Marinette, 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 Marinette, 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 Marinette, United States

Topographical Features Around Marinette

The topography surrounding Marinette, Wisconsin is characterized by relatively gentle terrain typical of the Great Lakes region. The city sits along the banks of the Menominee River where it flows into Green Bay, part of Lake Michigan. This location places Marinette in a transitional zone between the lake plain and the more elevated inland areas.

The immediate vicinity features low-lying areas near the waterfront that gradually rise toward the northwest and west. Elevations in the region generally range from around 580 feet above sea level near the water to approximately 800-900 feet in the higher inland areas. The landscape is predominantly rolling hills with occasional steeper slopes, but nothing that would be considered mountainous terrain.

Much of the surrounding countryside consists of mixed agricultural land and forested areas, with numerous small lakes and wetlands scattered throughout the region. The soil composition includes glacial deposits left behind from the last ice age, creating a mix of sandy soils near the lake and heavier clay-based soils further inland.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations would be found in the agricultural areas southwest and west of Marinette. These zones offer several advantages including relatively flat to gently rolling terrain that requires minimal grading for solar panel installation. The open farmland provides extensive cleared areas without the need for significant tree removal, which reduces development costs and environmental impact.

Areas approximately 5-15 miles inland from the immediate lakeshore would be particularly well-suited for solar development. This distance provides enough separation from the more densely developed waterfront areas while still maintaining reasonable access to existing electrical infrastructure. The slightly elevated terrain in these zones also offers better drainage compared to the lower-lying areas closer to Green Bay.

The agricultural lands to the southwest, extending toward the communities of Crivitz and Pound, present especially favorable conditions. These areas feature large contiguous parcels of relatively flat land with southern-facing slopes that would be ideal for solar panel orientation. The existing road network in these farming communities would facilitate construction access and ongoing maintenance operations.

Developers should avoid the heavily forested areas to the north and northwest, as well as the numerous wetland areas scattered throughout the region. The immediate shoreline areas, while offering unobstructed views, may face additional regulatory challenges due to their proximity to sensitive coastal environments and existing residential development.
