Andover, Minnesota, located in the United States at coordinates 45.2425, -93.2841, presents a viable but seasonally variable location for solar PV energy generation. This northern temperate zone location experiences significant seasonal fluctuations in solar production potential throughout the year.

Seasonal Solar Production

Solar energy production in Andover varies substantially across seasons. Summer stands out as the most productive period, generating an impressive 6.72kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 5.25kWh/day per installed kilowatt.

Production decreases considerably during autumn, dropping to 3.19kWh/day per kilowatt. Winter represents the greatest challenge for solar generation in Andover, with output falling to just 2.22kWh/day per kilowatt—roughly a third of summer production values.

Optimal Panel Positioning

For fixed solar panel installations in Andover, the ideal tilt angle to maximize year-round energy production is 39 degrees facing South. This angle has been calculated by analyzing daily solar elevation patterns at this latitude, weighted according to the location's solar irradiance potential throughout the year.

Environmental and Weather Considerations

Several significant factors may impede solar production in Andover. Snowfall represents the most substantial challenge, as Minnesota experiences considerable winter snow accumulation that can cover panels and dramatically reduce output during the already low-production winter months. Installing panels at the recommended 39-degree tilt helps with natural snow shedding, though periodic manual clearing may still be necessary after heavy snowfalls.

Extended periods of cloud cover, particularly during winter months, further reduce the already diminished solar radiation. This regional characteristic cannot be avoided but should be factored into production expectations.

Tree shading could also impact production, especially with the sun's lower winter path across the sky creating longer shadows. Careful site assessment and strategic tree management around the installation area can minimize this issue.

Preventative measures worth considering include:

• Snow removal systems (manual or automated)
• Slightly increased tilt angles if winter production is prioritized
• Regular panel cleaning to remove dust and pollen accumulation in spring and summer
• Selecting panels with anti-soiling glass coatings to maximize light absorption

While Andover isn't ideal for year-round consistent solar production, a properly designed system can still provide significant energy, particularly from late spring through early fall when production rates are highest.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 39° South in Andover, Minnesota, United States

To maximize your solar PV system's energy output in Andover, Minnesota, United States (Lat/Long 45.2425, -93.2841) 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 Andover, 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 Andover, 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 Andover, Minnesota, 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 Andover, 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 Andover, Minnesota, United States

The topography around Andover, Minnesota is characterized by gently rolling terrain typical of the greater Minneapolis-St. Paul metropolitan area. Located in Anoka County, the landscape was largely shaped by glacial activity during the last ice age, resulting in a mix of subtle hills, shallow depressions, and relatively flat expanses. The elevation generally ranges between 850 and 950 feet above sea level, with minimal dramatic changes in elevation. Andover sits within the Mississippi River watershed, and the area features numerous wetlands, small lakes, and streams that dot the landscape. These water features create a mosaic pattern across the otherwise modestly undulating terrain. The soil composition tends toward sandy loam in many areas, a legacy of the glacial deposits that form the foundation of the region.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic development near Andover, several topographical factors should be considered. The most suitable areas would be: The gently sloping south-facing hillsides throughout the region offer ideal conditions for solar collection. These natural features provide optimal sun exposure throughout the day while minimizing the need for extensive grading or site preparation. The agricultural and former agricultural lands that surround Andover present excellent opportunities for solar development. These areas typically feature cleared, relatively flat terrain with minimal shading from trees or structures. The open expanses allow for efficient arrangement of solar arrays with minimal site preparation costs. The slightly elevated plateaus found to the north and west of Andover's center provide good solar potential. These areas tend to have fewer wetlands and water features, reducing environmental complications for development while offering stable ground conditions. Areas to avoid would include the numerous wetlands and lowlands that characterize portions of the region, as these present both environmental sensitivity concerns and practical installation challenges. Additionally, heavily forested sections would require significant clearing, increasing both the environmental impact and development costs. The relatively minor elevation changes throughout the region mean that most areas receive comparable sunlight exposure, making the primary considerations for solar development related to current land use, access to transmission infrastructure, and avoiding environmentally sensitive areas rather than dramatic topographical variations.
