Oak Grove, Minnesota, situated in the United States at coordinates 45.3398, -93.245, offers a variable environment for solar PV energy generation throughout the year. This northern temperate location experiences significant seasonal fluctuations in solar production potential.
Seasonal Solar Production
Solar panels in Oak Grove perform best during summer months, generating approximately 6.72kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.25kWh/day. Production decreases considerably during autumn (3.19kWh/day) and reaches its lowest point in winter (2.22kWh/day).
This seasonal pattern creates a production ratio of approximately 3:1 between the best and worst seasons, with summer generating about three times the electricity of winter months. The substantial difference highlights the variability of solar potential at this northern location.
Optimal Panel Installation
For fixed solar panel installations in Oak Grove, the ideal tilt angle to maximize year-round production is 39 degrees facing South. This specific angle optimizes the annual solar harvest by balancing seasonal variations and accounting for the Earth's elliptical orbit and the location's position in the Northern Temperate Zone.
Environmental Considerations
Several environmental factors can impact solar production in Oak Grove:
- Snow accumulation during Minnesota winters can significantly reduce output by blocking sunlight from reaching panels. Installing panels at the recommended 39-degree tilt helps with natural snow shedding, while periodic clearing may be necessary during heavy snowfall periods.
- Minnesota's cold climate actually benefits solar efficiency, as panels operate more efficiently in cooler temperatures, partially offsetting the reduced winter sunlight.
- Oak Grove experiences approximately 44 inches of annual precipitation, including snowfall. Ensuring proper drainage systems and mounting hardware resistant to moisture damage is essential.
Despite the seasonal variations, Oak Grove receives sufficient solar radiation to make PV installations viable, particularly if sized appropriately to account for the winter production decrease. The substantial summer and spring production can make up for reduced winter output in properly designed systems.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 39° South in Oak Grove, Minnesota, United States
To maximize your solar PV system's energy output in Oak Grove, Minnesota, United States (Lat/Long 45.3398, -93.245) 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 Oak Grove, 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 Oak Grove, 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 Oak Grove, 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 Oak Grove, Minnesota, 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 Oak Grove, Minnesota, United States
The topography surrounding Oak Grove, Minnesota is characterized by a gentle, rolling landscape typical of the Upper Midwest region. Located in Anoka County, this area sits within the glaciated terrain of central Minnesota, shaped by the retreat of ice sheets during the last ice age. The land features subtle elevation changes rather than dramatic hills or valleys, with elevations generally ranging between 850 and 900 feet above sea level. The terrain consists of a mix of flat plains interspersed with modest hills, shallow depressions, and subtle ridges. These glacial features create a varied but not extreme topographical profile. The area includes numerous wetlands, small lakes, and ponds scattered throughout the landscape, which are remnants of glacial activity. The Rum River, a tributary of the Mississippi, flows through the region, adding riparian elements to the topography.
Vegetation and Land Use
Oak Grove and its surroundings feature a combination of deciduous woodlands, open grasslands, and agricultural fields. The natural vegetation includes oak savannas (as the name suggests), maple-basswood forests, and prairie remnants. Much of the original landscape has been modified for agricultural use and residential development, though significant natural areas remain.Solar Potential Areas
For large-scale solar photovoltaic development, the most suitable areas near Oak Grove would be: The agricultural plains to the west and northwest of Oak Grove present ideal conditions for solar installations. These areas feature relatively flat terrain with minimal shading obstacles and have already been cleared for farming, reducing environmental impact and site preparation costs. Former farmland or fallow fields throughout the region offer good potential. These areas typically have favorable drainage, established access roads, and limited tree cover that would otherwise cast shadows on solar arrays. The slightly elevated ridges and hills in the area, particularly those with southern exposures, could be advantageous for solar collection efficiency. These subtle rises in the landscape can sometimes receive better solar exposure than completely flat terrain. Areas away from the wetland complexes and water features would be preferable, as these locations avoid potential environmental complications and flooding risks. The drier upland areas provide more stable ground conditions for mounting solar infrastructure.Topographical Considerations
The modest elevation changes in the region generally don't pose significant challenges for solar development. The gentle slopes can actually be beneficial, as slight south-facing inclines naturally optimize the angle for solar collection in this northern latitude. The glacial till soils common in the area typically provide good stability for ground-mounted solar systems, though site-specific geotechnical assessment would be necessary for any large installation. Winter conditions should be considered in site selection, as the rolling topography can create areas of snow accumulation or drifting. Slightly elevated positions with good air circulation might help minimize snow cover duration on solar panels. The region's network of rural roads and existing electrical infrastructure makes many areas accessible for development and grid connection, though proximity to substations and transmission capacity would need to be evaluated for specific locations.United States solar PV Stats as a country
