The location of Ishpeming, Michigan, in the United States, presents both opportunities and challenges for solar PV energy generation. Situated in the Northern Temperate Zone, this area experiences significant seasonal variations in solar energy production.

Seasonal Solar Output

Summer stands out as the most productive season, with an impressive 6.39 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, generating 4.89 kWh daily. Autumn sees a considerable drop to 2.87 kWh per day, while winter experiences the lowest output at just 1.52 kWh daily.

These figures highlight the stark contrast between summer and winter production, with summer yielding more than four times the energy of winter months. This disparity underscores the importance of maximizing energy collection during the longer, sunnier days of late spring through early fall.

Optimal Panel Installation

To achieve the best year-round performance, fixed solar panels should be tilted at a 39-degree angle facing south. This orientation helps capture the most sunlight throughout the year, balancing the low winter sun angle with the higher summer sun position.

Environmental Considerations

Ishpeming's location presents several challenges for solar energy production:

1. Snow accumulation: Heavy snowfall can significantly reduce panel efficiency during winter months.
2. Cloud cover: The region experiences frequent overcast conditions, particularly in autumn and winter.

To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off. Additionally, use high-efficiency panels and micro-inverters to maximize production during periods of lower light. Regular panel cleaning and maintenance, especially after snowstorms, can help ensure optimal performance year-round.

While Ishpeming may not be ideal for solar PV generation compared to sunnier locations, proper system design and maintenance can still yield substantial energy production, particularly during the extended daylight hours of summer months.

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 Ishpeming

Seasonal solar PV output for Latitude: 46.4885, Longitude: -87.6676 (Ishpeming, 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 Ishpeming, United States

To maximize your solar PV system's energy output in Ishpeming, United States (Lat/Long 46.4885, -87.6676) 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 Ishpeming, 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 Ishpeming, 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
30° South in Summer	50° South in Autumn	60° South in Winter	39° 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 Ishpeming, 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 Ishpeming, 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 Ishpeming, United States

The topography around Ishpeming, Michigan, is characterized by its rugged and varied landscape, typical of the Upper Peninsula region. Located in Marquette County, Ishpeming sits atop a hilly area that was shaped by glacial activity thousands of years ago. The terrain is a mix of rolling hills, rocky outcrops, and numerous small lakes and ponds scattered throughout the region. The area surrounding Ishpeming features dense forests, primarily composed of hardwood and coniferous trees. These wooded areas are interspersed with open spaces, including cleared land for agriculture and former mining sites. The elevation in and around Ishpeming varies significantly, with some hills rising several hundred feet above the surrounding landscape.

Nearby Water Bodies

Several notable water bodies are found near Ishpeming. To the north lies Lake Superior, the largest of the Great Lakes, which has a significant influence on the region's climate and topography. Closer to the city, there are numerous smaller lakes and rivers, including Teal Lake to the northeast and the Carp River to the southeast.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, there are a few factors to consider. The ideal locations would be relatively flat, open areas with good sun exposure and minimal shading from trees or hills. Some potential areas that might be suitable include: 1. Former mining sites: The region has a history of iron ore mining, and some of these now-defunct mining areas could potentially be repurposed for solar installations. These sites often have large, open spaces with minimal vegetation. 2. Agricultural land: Some of the cleared farmland in the surrounding area might be suitable for solar PV installations, particularly if it's less productive for crops. 3. Industrial parks: Existing or planned industrial areas on the outskirts of Ishpeming or neighboring communities might have suitable flat, open spaces for solar installations. It's important to note that while the Upper Peninsula receives ample sunlight during the summer months, the region experiences long, dark winters with significant snowfall. This could impact the overall efficiency and viability of large-scale solar projects in the area. Additionally, any potential solar installation would need to carefully consider the local ecosystem, wildlife habitats, and community needs before development.
