Neenah, Wisconsin shows moderate suitability for year-round solar energy generation, though with significant seasonal variations typical of its Northern Temperate Zone location. The solar output data reveals a clear pattern of higher production during warmer months and substantially reduced generation during winter.
Seasonal Solar Performance
Summer represents the peak solar generation period at this location, producing 6.45 kWh per day per kW of installed capacity. This strong summer performance makes it an excellent time for solar energy production. Spring follows as the second-best season with 5.11 kWh per day per kW, offering good solar generation as daylight hours increase and weather conditions improve. Autumn sees a notable decline to 3.13 kWh per day per kW as the region transitions toward winter conditions. Winter presents the most challenging period for solar generation, dropping significantly to just 2.08 kWh per day per kW of installed capacity. For maximum year-round energy production from a fixed solar panel installation at Neenah, the optimal tilt angle is 38 degrees facing south. This angle is calculated by analyzing the sun's elevation throughout the year and weighting these angles according to solar irradiance potential.Local Factors Affecting Solar Production
Several environmental and weather factors in Neenah can significantly impact solar energy generation:- Heavy snow accumulation during Wisconsin winters can cover panels and block sunlight
- Frequent cloud cover and overcast conditions, particularly during autumn and winter months
- Ice formation on panels during freezing periods
- Strong winds that can affect panel positioning and create debris issues
Preventative Installation Measures
To maximize solar production despite these challenges, several installation strategies prove effective. Installing panels at the optimal 38-degree tilt helps snow slide off more easily rather than accumulating on flat surfaces. This steep angle also improves winter sun exposure when the sun sits lower in the sky. Ensuring adequate spacing between panel rows prevents snow buildup and shading issues. Installing panels with sufficient ground clearance allows snow to fall away from the installation area. Using high-quality mounting systems designed for Wisconsin's wind loads and weather conditions ensures panels remain properly positioned. Regular maintenance becomes particularly important in this climate. Keeping panels clear of snow, ice, and debris during winter months can significantly improve energy production during the already-challenging low-production season. Some installations benefit from heated panel systems or easy-access designs that facilitate snow removal. Despite the winter production challenges, Neenah's strong summer and spring solar generation periods make it a reasonably viable location for solar energy, especially when proper installation techniques address the local environmental factors.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 Neenah
Seasonal solar PV output for Latitude: 44.1811, Longitude: -88.4762 (Neenah, 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 Neenah, United States
To maximize your solar PV system's energy output in Neenah, United States (Lat/Long 44.1811, -88.4762) 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 Neenah, 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 Neenah, 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.

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 Neenah, United States.
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 Neenah, United States
Topographical Features Around Neenah
The landscape surrounding Neenah, Wisconsin is characterized by relatively gentle terrain typical of the upper Midwest. The area sits within the Eastern Ridges and Lowlands region, featuring rolling hills with modest elevation changes and numerous water bodies. Lake Winnebago, Wisconsin's largest inland lake, lies immediately to the east of the city, while the Fox River flows northeastward through the urban area toward Green Bay. The topography consists primarily of glacially-formed features, including drumlins, moraines, and outwash plains left behind by retreating ice sheets thousands of years ago. Elevation changes are generally gradual, with most areas ranging from approximately 750 to 900 feet above sea level. The terrain includes a mix of agricultural fields, scattered woodlots, wetlands, and developed areas, creating a patchwork landscape across the region.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the expansive agricultural fields that dominate the landscape west and southwest of Neenah. These areas offer several advantages including minimal topographical obstacles, existing cleared land, and generally good southern exposure. The relatively flat to gently rolling farmland provides ideal conditions for mounting solar arrays without requiring significant grading or earthwork. Areas along the higher elevations of the glacial ridges, particularly those running north-south through the region, present excellent opportunities for solar development. These elevated positions often provide unobstructed exposure to sunlight throughout the day while avoiding the shadowing effects that can occur in lower-lying areas surrounded by trees or buildings. The open agricultural zones extending toward Oshkosh to the southwest and toward Appleton to the west contain some of the most promising sites. These locations benefit from minimal tree coverage, good accessibility via existing farm roads, and proximity to electrical infrastructure. The gentle slopes in these areas are typically well-suited for optimal solar panel positioning without requiring extensive site preparation. Areas immediately adjacent to Lake Winnebago should generally be avoided for large installations due to environmental sensitivities, while the more heavily forested regions to the north and northwest would require significant clearing and may face greater regulatory challenges. The existing urban and suburban development patterns create a patchwork that limits opportunities for very large contiguous installations within the immediate vicinity of the city itself.United States solar PV Stats as a country
