Solar PV Analysis of Prior Lake, United States
Prior Lake, Minnesota, located in the Northern Temperate Zone, presents a mixed scenario for solar energy generation throughout the year. This location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Prior Lake, with an impressive 6.84 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.28 kWh/day. However, the output drops considerably during autumn (3.42 kWh/day) and reaches its lowest point in winter (2.32 kWh/day).
These figures indicate that solar energy production in Prior Lake is most effective from late spring through early fall. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimal Panel Installation
To maximize year-round solar production in Prior Lake, fixed solar panels should be installed at a tilt angle of 39 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and seasonal sun positions.
Environmental and Weather Considerations
Several factors can impact solar energy production in Prior Lake:
- Snow accumulation in winter can significantly reduce panel efficiency
- Cloudy days, particularly common in late fall and winter, can decrease output
- Potential shading from trees or nearby structures may affect performance
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off, using snow-clearing tools when necessary, and ensuring proper placement to minimize shading. Additionally, high-efficiency panels and micro-inverters can help maximize production even under less-than-ideal conditions.
While Prior Lake's location presents challenges for year-round solar energy production, particularly in winter, the strong performance during summer and spring makes it a viable option for supplementing energy needs. With proper installation and maintenance, solar PV systems can still provide significant benefits to homeowners and businesses in this area.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Prior Lake
Seasonal solar PV output for Latitude: 44.7098, Longitude: -93.4129 (Prior Lake, 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 Prior Lake, United States
To maximize your solar PV system's energy output in Prior Lake, United States (Lat/Long 44.7098, -93.4129) 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 Prior Lake, 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 Prior Lake, 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 |
|---|---|---|---|
| 28° South in Summer | 48° South in Autumn | 58° South in Winter | 37° 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 Prior Lake, 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 Prior Lake, 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 Prior Lake, United States
The topography around Prior Lake, Minnesota, is characterized by gently rolling hills and numerous small lakes, typical of the glacial landscape found in this part of the Midwest United States. Prior Lake itself is situated in a shallow depression, surrounded by low-lying areas and gradual slopes. The terrain is generally flat to slightly undulating, with occasional steeper hillsides near water bodies.
The area features a mix of open farmland, wooded areas, and suburban developments. The elevation changes are relatively modest, with most of the land ranging between 900 to 1,000 feet above sea level. This gentle topography is a result of glacial activity that occurred thousands of years ago, leaving behind a landscape dotted with lakes, wetlands, and subtle ridges.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would be:
- Open, flat or gently sloping farmland to the south and southwest of Prior Lake
- Areas with minimal tree cover and obstruction-free horizons
- Regions with good road access for construction and maintenance
- Locations near existing electrical infrastructure for easier grid connection
Specifically, the agricultural lands in Scott County and neighboring counties to the south and southwest of Prior Lake offer promising potential for solar PV development. These areas often feature large, open fields with minimal shading from trees or buildings, which is ideal for maximizing solar exposure throughout the day.
It's important to note that while the topography is generally favorable for solar installations, other factors such as local zoning regulations, environmental considerations, and community acceptance would also play crucial roles in determining the feasibility of large-scale solar projects in the region.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
