Solar PV Analysis of Vernon Hills, United States
Vernon Hills, Illinois, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. The location's solar potential varies significantly across seasons, with peak production during summer months and a noticeable decline in winter.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 6.24 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.20 kWh/day. Autumn sees a considerable drop to 3.17 kWh/day, while winter experiences the lowest output at just 1.80 kWh/day.
These figures indicate that Vernon Hills experiences substantial fluctuations in solar energy potential throughout the year. The location is most ideal for solar generation from late spring through early fall, with peak performance in the summer months when daylight hours are longest and sun angle is highest.
Optimal Panel Installation
To maximize year-round solar production in Vernon Hills, fixed solar panels should be tilted at a 36-degree angle facing south. This optimal angle helps balance energy capture across seasons, compensating for the sun's changing position in the sky throughout the year.
Environmental and Weather Considerations
Several factors in Vernon Hills may impact solar energy production:
- Snowfall: The area experiences significant snowfall in winter, which can cover panels and reduce efficiency. Regular panel cleaning or installing panels at a steeper angle can help mitigate this issue.
- Cloud cover: The region has frequent cloudy days, particularly in late fall and winter, which can reduce solar output. Using high-efficiency panels can help maximize energy capture even in less-than-ideal conditions.
To address these challenges, consider installing snow guards or heating elements on panels to prevent snow accumulation. Additionally, using microinverters or power optimizers can help maintain system efficiency during partial shading conditions caused by cloud cover or snow.
While Vernon Hills may not be the most ideal location for year-round solar energy production, proper system design and maintenance can still yield significant benefits, particularly during the more productive spring and summer months.
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 Vernon Hills
Seasonal solar PV output for Latitude: 42.2284, Longitude: -87.9722 (Vernon Hills, 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 36° South in Vernon Hills, United States
To maximize your solar PV system's energy output in Vernon Hills, United States (Lat/Long 42.2284, -87.9722) throughout the year, you should tilt your panels at an angle of 36° 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 Vernon Hills, 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 Vernon Hills, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 26° South in Summer | 46° South in Autumn | 57° South in Winter | 35° 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 Vernon Hills, 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 Vernon Hills, 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 Vernon Hills, United States
The topography around Vernon Hills, Illinois, in the United States, is characterized by gently rolling terrain typical of the Midwestern region. This area, located in Lake County, is part of the Chicago metropolitan area and sits on what was once glacial terrain. The landscape is generally flat to slightly undulating, with subtle variations in elevation.
Vernon Hills itself is situated at an elevation of around 690 feet (210 meters) above sea level. The surrounding area features a mix of low hills, shallow valleys, and some wetland areas. To the east, the terrain gradually slopes down towards Lake Michigan, while to the west, it remains relatively consistent with the local topography.
The region around Vernon Hills includes several small lakes and ponds, as well as forest preserves and open spaces. These natural features contribute to the area's gentle topographic variations. The Des Plaines River, which flows to the west of Vernon Hills, has shaped some of the local terrain, creating shallow river valleys and floodplains.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few considerations to keep in mind:
1. Open, flat areas: The most suitable locations for solar farms would be large, open spaces with minimal shading and relatively flat terrain. Agricultural land or former industrial sites to the west and northwest of Vernon Hills might offer potential.
2. Avoiding wetlands and forests: Areas to the north and northeast, which include more forested regions and nature preserves, would be less ideal due to environmental concerns and shading issues.
3. Proximity to infrastructure: Sites closer to existing electrical infrastructure and away from densely populated areas would be preferable. Areas to the west and southwest of Vernon Hills, where there's a transition to more rural landscapes, could offer suitable locations.
4. Considering future development: As the Chicago metropolitan area continues to expand, it's important to select sites that are less likely to be needed for urban development in the near future.
5. Zoning and land use: Any potential site would need to comply with local zoning laws and land use regulations, which may limit options in this suburban area.
While the immediate vicinity of Vernon Hills may have limited space for large-scale solar installations due to suburban development, exploring options in the surrounding rural areas of Lake County or neighboring counties could yield more suitable locations for solar PV projects.
