La Crescent, Minnesota, located in the Northern Temperate Zone, presents a varied landscape for solar PV energy generation throughout the year. The location's seasonal solar output fluctuates significantly, reflecting the region's distinct climate patterns.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.52 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, yielding 5.04 kWh daily. Autumn sees a notable decrease to 3.35 kWh, while winter experiences the lowest output at 2.26 kWh per day.

These figures highlight the substantial difference between peak and off-peak seasons, with summer generating nearly three times the energy of winter. This variance underscores the importance of efficient energy storage and management systems to balance production throughout the year.

Optimal Panel Positioning

For fixed panel installations in La Crescent, the ideal tilt angle is 38 degrees facing south. This angle maximizes year-round solar energy capture, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While La Crescent's location is generally favorable for solar energy, there are some environmental factors to consider:

• Snowfall: Minnesota's winters can bring heavy snow, potentially covering panels and reducing efficiency. Regular panel cleaning and snow removal systems can mitigate this issue.
• Cloud cover: The region experiences significant cloud cover, especially in winter months. Using high-efficiency panels and microinverters can help maximize energy production even in less-than-ideal conditions.

Despite these challenges, La Crescent's location offers good potential for solar energy generation, particularly from late spring through early fall. Implementing strategies to address winter-related issues can help maintain consistent energy production year-round.

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 La Crescent

Seasonal solar PV output for Latitude: 43.828, Longitude: -91.304 (La Crescent, 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 38° South in La Crescent, United States

To maximize your solar PV system's energy output in La Crescent, United States (Lat/Long 43.828, -91.304) throughout the year, you should tilt your panels at an angle of 38° 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 La Crescent, 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 La Crescent, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
27° South in Summer	48° South in Autumn	57° 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 La Crescent, 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 La Crescent, 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 La Crescent, United States

La Crescent, located in southeastern Minnesota, is situated in a region characterized by diverse and picturesque topography. The area is part of the Driftless Region, which was largely untouched by glaciers during the last ice age. This unique geological history has resulted in a landscape that is quite different from the flat prairies often associated with the Midwest. The topography around La Crescent is dominated by steep bluffs, rolling hills, and deeply carved river valleys. The city itself sits at the base of these bluffs, nestled along the Mississippi River. To the east, the mighty Mississippi forms a natural border with Wisconsin, while to the west, the land rises dramatically into a series of forested ridges and valleys. These bluffs, some reaching heights of 500 feet or more above the river, offer stunning views of the surrounding area. They are often covered in dense hardwood forests, adding to the region's natural beauty. The valleys between these bluffs are typically narrow and steep-sided, with small streams and creeks winding their way down to the Mississippi.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal location would have relatively flat terrain, good sun exposure, and be easily accessible for construction and maintenance. Given the hilly nature of the immediate surroundings, the most suitable areas for solar PV development would likely be found in the broader river valleys or on the plateaus atop some of the bluffs. These areas tend to have more level ground and potentially better sun exposure throughout the day. Specifically, the agricultural lands to the north and northwest of La Crescent, stretching towards Winona, might offer promising locations. These areas have more open, gently rolling terrain that could accommodate large solar arrays without requiring extensive land modification. Another potential area could be the flatter regions to the southwest, moving towards the city of La Crosse, Wisconsin. This area, while still featuring some hills, has larger expanses of open land that could be suitable for solar development. It's important to note that any large-scale solar project would need to carefully consider environmental impacts, especially given the region's unique ecology. The steep bluffs and forested areas, while scenic, would likely be challenging and potentially environmentally disruptive for solar development. Therefore, focusing on already cleared agricultural land or less ecologically sensitive areas would be the most prudent approach for potential solar PV installations in this 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.
