Mosinee, Wisconsin, situated in the Northern Temperate Zone, presents a mixed landscape for solar energy generation. This location 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 Mosinee, with an impressive daily output of 6.47 kWh per kW of installed solar capacity. Spring follows as the second-best season, yielding 5.16 kWh/day. However, the colder months see a substantial drop in production, with autumn generating 3.28 kWh/day and winter falling to a mere 2.19 kWh/day.
These figures highlight the stark contrast between the warm and cold seasons, with summer producing nearly three times the energy of winter. This variation underscores the importance of efficient energy storage and management systems to balance the fluctuating supply throughout the year.
Optimal Panel Installation
To maximize year-round solar energy production in Mosinee, fixed solar panels should be tilted at a 39-degree angle facing south. This optimal angle has been calculated to capture the most sunlight across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.
Environmental Considerations
While Mosinee's location is generally suitable for solar energy production, there are some environmental factors that could potentially impact system performance:
- Snowfall: Wisconsin's winters can bring heavy snowfall, which may temporarily cover solar panels and reduce efficiency.
- Cloud cover: The region experiences significant cloud cover, particularly during winter months, which can decrease solar irradiance.
To mitigate these challenges, consider implementing the following measures:
- Install panels at a steeper angle to promote snow sliding off more easily.
- Use snow-shedding coatings on panels to minimize snow accumulation.
- Implement a regular cleaning schedule to remove snow and debris.
- Consider using bifacial solar panels to capture reflected light from snow, potentially increasing winter production.
By addressing these factors and optimizing panel installation, Mosinee residents can maximize their solar energy production despite the seasonal variations and environmental challenges.
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 Mosinee
Seasonal solar PV output for Latitude: 44.793, Longitude: -89.7032 (Mosinee, 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 39° South in Mosinee, United States
To maximize your solar PV system's energy output in Mosinee, United States (Lat/Long 44.793, -89.7032) throughout the year, you should tilt your panels at an angle of 39° 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 Mosinee, 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 Mosinee, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° 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 | 49° South in Autumn | 58° 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.

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 Mosinee, United States
The topography around Mosinee, Wisconsin, in the United States, is characterized by a diverse landscape that reflects the region's glacial history. Located in Marathon County, Mosinee sits in an area known for its gently rolling hills, expansive forests, and numerous water features. The terrain surrounding Mosinee is primarily composed of low, undulating hills interspersed with flat areas. These hills are remnants of ancient glacial activity, which shaped the land during the last ice age. The Wisconsin River, a major waterway in the state, flows through Mosinee, carving a shallow valley and contributing to the area's varied topography. Forests dominate much of the landscape around Mosinee, with a mix of deciduous and coniferous trees covering the hillsides and flat areas. These woodlands are punctuated by clearings, agricultural fields, and scattered wetlands, creating a patchwork of different land uses and habitats.
Potential Areas for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Mosinee, several factors come into play. The most suitable areas would be those with relatively flat terrain, good sun exposure, and minimal obstructions. Agricultural lands to the east and southeast of Mosinee present promising opportunities for solar PV development. These areas often feature expansive, open fields with fewer trees, providing excellent sun exposure throughout the day. The gently sloping terrain in these locations can also be advantageous for solar panel placement, allowing for optimal angling towards the sun. Some of the cleared areas within the forested regions surrounding Mosinee could also be potential sites for solar installations. However, care would need to be taken to ensure that nearby trees do not cast shadows on the panels, reducing their efficiency. It's important to note that while the topography around Mosinee offers some suitable locations for solar PV, the region's climate, characterized by long, cold winters and relatively short summers, may present challenges for year-round solar energy production. Nevertheless, with advancing solar technology and careful site selection, large-scale solar PV installations could still be viable in this area, contributing to renewable energy efforts in central Wisconsin.United States solar PV Stats as a country
