Evansville, Minnesota, located at 46.0041° N, 95.6828° W in the Northern Temperate Zone, offers varying solar energy production potential throughout the year. The solar electricity output displays significant seasonal fluctuations, with the highest production occurring during summer months and substantially lower generation in winter.

Seasonal Solar Production

Solar panels in Evansville generate their maximum electricity during summer, producing about 6.76 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.27 kWh/day. Production decreases considerably in autumn to 3.07 kWh/day, while winter represents the lowest output period with just 1.96 kWh/day per installed kilowatt.

This seasonal pattern means Evansville residents can expect roughly 3.5 times more solar energy production in summer compared to winter months. The substantial difference highlights the importance of properly sizing a solar system to accommodate year-round energy needs, particularly during the less productive winter period.

Optimal Panel Installation

For fixed solar panel installations in Evansville, the ideal tilt angle is 39 degrees facing South. This specific angle maximizes total annual energy production by optimizing the panels' exposure to the sun's path throughout the year. Proper orientation at this angle helps compensate somewhat for seasonal variations in solar production.

Environmental and Weather Considerations

Several significant factors can affect solar production in Evansville:

• Snow accumulation during Minnesota's harsh winters can temporarily cover panels, reducing or eliminating production until cleared
• Frequent cloud cover during winter months compounds the already reduced daylight effectiveness
• Extremely cold temperatures, while generally beneficial for panel efficiency, can create issues with other system components
• Tree shading may be problematic in this heavily forested region

Preventative Measures

To maximize production despite these challenges, several installation considerations are recommended:

• Install panels at a steeper angle than the standard 39 degrees if winter production is particularly important, as this helps shed snow more effectively
• Implement snow removal protocols for winter months, potentially including accessible panel placement or specialized removal tools
• Consider ground-mounted systems in open areas to minimize tree shading issues
• Use microinverters or power optimizers to minimize production losses when partial shading occurs
• Select cold-weather rated components designed to withstand Minnesota's temperature extremes

With proper system design accounting for these local factors, solar energy remains a viable option for Evansville residents, particularly when sized appropriately to accommodate the significant seasonal production differences.

Solar output per kW of installed solar PV by season in Evansville, Minnesota

Seasonal solar PV output for Latitude: 46.0041, Longitude: -95.6828 (Evansville, Minnesota, 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 Evansville, Minnesota, United States

To maximize your solar PV system's energy output in Evansville, Minnesota, United States (Lat/Long 46.0041, -95.6828) 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 Evansville, Minnesota, 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 Evansville, Minnesota, 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
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 Evansville, Minnesota, 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 Evansville, Minnesota, United States

The landscape surrounding Evansville, Minnesota, exhibits the characteristic features of the Western Minnesota Prairie region. This area is part of the broader Northern Glaciated Plains ecoregion, shaped significantly by glacial activity during the last ice age. The topography is predominantly gently rolling to flat, with subtle elevation changes across the terrain. Evansville sits at an elevation of approximately 1,250 feet above sea level, with the surrounding countryside showing modest variations in height. The area features a mix of agricultural lands, scattered woodlands, and numerous small lakes and wetlands - a direct result of glacial deposits and meltwater. The nearby Lake Christina and smaller water bodies dot the landscape, creating a patchwork of land and water features. The soil composition tends toward fertile glacial till, which has made the region valuable for farming but also provides stable ground conditions for other land uses.

Solar PV Suitability in the Evansville Region

For large-scale solar photovoltaic installations, several areas around Evansville offer promising conditions. The gently rolling farmlands to the south and west of Evansville present particularly favorable topography for solar development. These areas combine several advantageous characteristics: The relatively flat terrain requires minimal grading during construction, reducing development costs and environmental disruption. Open agricultural fields provide large contiguous spaces that could accommodate utility-scale installations without major land clearing. The modest elevation changes in these areas can actually be beneficial, as slight south-facing slopes can optimize solar panel orientation. The northwestern Minnesota region generally experiences clear atmospheric conditions throughout much of the year, particularly during summer months when solar potential peaks. While winter brings shorter days, the reflective properties of occasional snow cover can enhance solar collection efficiency during those periods. Areas to potentially avoid include the immediate surroundings of Lake Christina and other wetland complexes to the northeast, which may face regulatory constraints and have higher ecological sensitivity. Similarly, the more heavily wooded sections scattered throughout the region would require clearing, increasing both environmental impact and development costs. The grid infrastructure in the region, though not as robust as in metropolitan areas, includes transmission lines that could potentially support solar development, particularly along the major transportation corridors. Proximity to existing electrical infrastructure should be a key consideration when identifying specific development sites. Agricultural lands currently in production would need careful evaluation to balance food production with energy generation needs, though dual-use approaches including agrivoltaics could be considered in some locations to maintain agricultural productivity while generating clean energy.
