Solar Energy Potential in Tawas City, Michigan

Tawas City, Michigan, in the United States, offers varying potential for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this location experiences significant seasonal fluctuations in solar energy production. The solar output varies dramatically across seasons. Summer stands out as the most productive period with an average of 6.27kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, generating 5.14kWh per day. Autumn production drops considerably to 2.90kWh per day, while winter shows the lowest output at just 1.63kWh per day.

Seasonal Considerations

This seasonal pattern makes Tawas City a location of contrasts for solar energy. The summer months provide excellent generation potential, with long days and typically clearer skies maximizing panel efficiency. Spring also offers strong production capabilities as daylight hours increase and temperatures remain moderate, which helps panel efficiency. The significant drop in autumn and particularly winter production presents challenges for year-round reliance on solar energy. Winter output is less than one-third of summer production, which means supplementary energy sources or substantial battery storage would be necessary during the colder months.

Optimal Panel Installation

For fixed panel installations in Tawas City, the ideal angle to maximize year-round energy production is 37 degrees tilted toward the South. This carefully calculated angle balances the seasonal variations in sun position to capture the most solar energy across the entire year.

Environmental and Weather Factors

Several significant factors could impede solar production in Tawas City:

• Snow accumulation is a major concern during winter months, which can completely cover panels and halt production
• Cloud cover is common in the Great Lakes region, particularly during late autumn and winter
• Ice storms can damage equipment and create opaque layers on panels
• Tree coverage and shading may be issues in this forested region

To mitigate these challenges, several preventative measures are recommended. Installing panels at the steeper 37-degree angle helps shed snow more effectively than flatter installations. Snow removal systems, whether manual or automated, should be considered essential. Additionally, micro-inverters or power optimizers can help minimize production losses when portions of arrays are shaded or covered. Finally, careful site selection to avoid tree shading, particularly from the southern exposure, is crucial for maximizing energy capture. Given these considerations, Tawas City represents a moderate location for solar energy production, with excellent potential during warmer months but significant challenges during the winter season.

Solar output per kW of installed solar PV by season in Tawas City

Seasonal solar PV output for Latitude: 44.2704, Longitude: -83.5487 (Tawas City, 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 37° South in Tawas City, United States

To maximize your solar PV system's energy output in Tawas City, United States (Lat/Long 44.2704, -83.5487) throughout the year, you should tilt your panels at an angle of 37° 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 Tawas City, 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 Tawas City, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° 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 Tawas City, 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 Tawas City, United States

The landscape around Tawas City, Michigan presents a captivating blend of natural features characteristic of northeastern Michigan's coastal region. Situated along the western shore of Lake Huron at the base of Tawas Bay, this area exemplifies the transition between the Great Lakes shoreline and the interior woodlands of Michigan's Lower Peninsula.

Coastal Features

The eastern edge of Tawas City borders the gentle waters of Tawas Bay, which is partially sheltered by the extending arm of Tawas Point. This sandy peninsula curves northeastward, creating a natural harbor and moderating the impact of Lake Huron's waves. The shoreline itself consists primarily of sandy beaches that gradually rise into low bluffs in some sections. Moving inland from the shore, the terrain exhibits a gentle rise with elevation gradually increasing from the lake level (approximately 577 feet above sea level) to rolling inland areas that reach heights of 650-800 feet. This gradual ascent creates a series of subtle terraces, evidence of ancient shorelines from when glacial Lake Huron covered more extensive areas.

Inland Topography

The western portions of the Tawas area feature gently rolling hills, small valleys, and occasional wetland depressions—all remnants of glacial activity that shaped this region thousands of years ago. The landscape is characterized by modest relief, with few dramatic changes in elevation. Several small streams and drainage channels cut across the terrain, flowing eastward toward Lake Huron. Approximately 5-10 miles west of Tawas City, the terrain becomes slightly more pronounced with the beginning of the Huron National Forest, where the landscape transitions into more substantial hills covered with mixed hardwood and conifer forests. This area represents the eastern edge of Michigan's northern forest ecosystem.

Soil Composition

The soils around Tawas City vary considerably, reflecting the region's glacial history. Near the shoreline, sandy soils predominate, while moving inland reveals a mix of sandy loams, clay deposits, and occasional gravelly patches. These soil variations influence drainage patterns and vegetation throughout the area.

Potential Solar PV Development Areas

For large-scale solar photovoltaic development, several areas near Tawas City offer promising conditions:

Former Agricultural Lands

The most suitable locations for solar PV development can be found in the flat to gently rolling former agricultural lands located 3-7 miles inland from Lake Huron. These areas, particularly west and southwest of Tawas City, offer several advantages: they typically feature cleared land with minimal shading concerns, relatively level topography requiring minimal grading, and reasonably good access to existing transportation infrastructure.

Reclaimed Industrial Sites

Several brownfield or previously developed industrial sites in the broader Iosco County area present opportunities for solar development without disrupting natural habitats. These locations often have existing grid connections and access roads, reducing development costs.

Topographical Considerations

The most favorable solar PV sites would be those with southern exposure on gentle slopes (ideally 5-10% grade facing south), which receive optimal sunlight throughout the day. Areas with minimal tree cover and good drainage characteristics would reduce installation costs and maximize energy production. Areas to avoid would include the immediate shoreline (subject to erosion and higher land values), wetland depressions (environmental sensitivity and poor drainage), and heavily forested sections of the Huron National Forest to the west (clearing costs and environmental concerns). The moderate relief of the landscape around Tawas City generally means that shading from topographical features is minimal, allowing for efficient solar collection across much of the area, particularly in the agricultural belt that runs parallel to the shoreline several miles inland.
