Menomonee Falls, Wisconsin, located in the Northern Temperate Zone, presents a moderate opportunity for solar energy generation throughout the year, with significant seasonal variations in production capacity.

Seasonal Solar Production

Solar panels in Menomonee Falls demonstrate considerable fluctuation in energy output across the seasons. Summer proves to be the most productive period, generating approximately 6.35kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 5.21kWh/day per installed kilowatt.

Energy production decreases substantially during autumn and winter months. Autumn yields about 3.20kWh/day, while winter production drops to its lowest point at just 2.13kWh/day per kilowatt of installed capacity. This represents nearly a 66% reduction in daily energy production from summer to winter.

Optimal Panel Installation

For fixed solar panel installations in Menomonee Falls, the ideal tilt angle to maximize year-round energy production is 37 degrees facing South. This specific angle optimizes the capture of available sunlight throughout the changing seasons, balancing the higher summer sun with the lower winter sun position.

Environmental and Weather Considerations

Several significant factors in Menomonee Falls can impact solar production:

• Snow accumulation during winter months can substantially reduce output by covering panels, requiring regular clearing or snow-shedding installation designs
• Frequent cloud cover in the Great Lakes region, particularly during late autumn and winter, contributes to the reduced production during these seasons
• Potential tree shading in this suburban area may create partial panel shading, especially when the sun is lower in the sky

To mitigate these challenges, solar installations in Menomonee Falls should incorporate several preventative measures. Panels can be installed at a slightly steeper angle than the optimal 37 degrees to facilitate snow sliding off more easily. Micro-inverters or power optimizers help minimize production losses from partial shading. Additionally, regular panel maintenance, including snow removal and cleaning, will help maintain efficiency throughout the year.

While the winter months present challenges for solar production in this location, the strong summer and spring performance can help offset these seasonal variations, making solar still viable when designed with these local factors in mind.

Solar output per kW of installed solar PV by season in Menomonee Falls

Seasonal solar PV output for Latitude: 43.1604, Longitude: -88.1173 (Menomonee Falls, 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 37° South in Menomonee Falls, United States

To maximize your solar PV system's energy output in Menomonee Falls, United States (Lat/Long 43.1604, -88.1173) throughout the year, you should tilt your panels at an angle of 37° 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 Menomonee Falls, 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 Menomonee Falls, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
27° South in Summer	47° South in Autumn	56° South in Winter	36° 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 Menomonee Falls, 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 Menomonee Falls, 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 Menomonee Falls, United States

Menomonee Falls, Wisconsin is situated within the Eastern Ridges and Lowlands geographical region of the state. The topography of the area is characterized by gently rolling hills, shallow valleys, and relatively modest elevation changes typical of glaciated terrain. This landscape was largely shaped during the last ice age when glaciers advanced and retreated across the region, leaving behind a mix of glacial deposits including moraines, drumlins, and eskers. The area sits at an average elevation of approximately 820 feet (250 meters) above sea level. The terrain features subtle undulations rather than dramatic relief, with elevation differences typically ranging between 50-100 feet across the broader region. The Menomonee River and its tributaries have carved shallow valleys through this glacial landscape, creating gentle slopes and occasional floodplains.

Geological Features

The underlying bedrock consists primarily of Paleozoic sedimentary rocks, mainly dolomite, limestone, and sandstone. However, these are largely covered by glacial till and outwash deposits of varying thickness. The soils tend to be relatively fertile loams and clay loams, though some areas feature sandy or gravelly compositions reflecting their glacial origins. To the west and northwest of Menomonee Falls, the terrain becomes slightly more pronounced as it transitions toward the Kettle Moraine region, where kettles (depressions formed by melting ice blocks) and moraines (ridges of glacial debris) create a more varied topography. To the east, the land gradually slopes toward Lake Michigan, about 20 miles away.

Solar PV Suitability

For large-scale solar photovoltaic (PV) development, several nearby areas offer promising conditions based on topographical considerations: The relatively flat agricultural lands to the west and northwest of Menomonee Falls present favorable conditions for solar development. These areas feature open spaces with minimal shading issues and gentle slopes primarily facing south or southwest, which is ideal for solar panel orientation in the Northern Hemisphere. Former agricultural lands or brownfield sites around the broader Waukesha County region could be particularly suitable. The gently rolling terrain provides natural drainage while minimizing grading requirements for installation. Areas with 1-3% slopes are generally optimal for solar farms, balancing drainage needs with construction simplicity. The rural areas north of Menomonee Falls toward Washington County offer expansive tracts with appropriate topography for solar development. These locations combine suitable terrain with proximity to existing electrical infrastructure, which is crucial for cost-effective grid integration. Areas to avoid include the steeper slopes associated with river valleys, particularly along the Menomonee River corridor, as these present more challenging construction conditions and potential erosion concerns. Similarly, low-lying areas prone to seasonal flooding would require additional site preparation and potentially raise environmental concerns. The glaciated landscape around Menomonee Falls ultimately provides many topographically suitable locations for solar development. The modest elevation changes, predominantly south-facing gentle slopes, and open terrain create favorable conditions for capturing solar energy efficiently while minimizing the earthwork required for installation.
