Auburn, Maine, in the United States offers varying solar energy potential throughout the year due to its northern temperate location. Situated at latitude 44.0938° N and longitude 70.2368° W, Auburn experiences significant seasonal fluctuations in solar electricity production.

Seasonal Solar Production

The solar energy output in Auburn follows a predictable seasonal pattern. Summer months are the most productive, generating approximately 5.62 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind with 5.12 kWh/day per installed kilowatt. Production drops considerably in autumn to 2.99 kWh/day, and reaches its lowest point during winter with just 1.78 kWh/day per kilowatt of installed capacity.

This pattern creates a roughly 3:1 ratio between summer and winter production, which is typical for locations in the northern United States. The substantial difference between seasons means that a solar system sized for winter needs would produce excess energy in summer, while one sized for summer needs would fall short in winter.

Optimal Panel Installation

For fixed solar panel installations in Auburn, the ideal tilt angle to maximize year-round energy production is 38 degrees facing south. This angle optimizes the balance between summer and winter solar collection, accounting for the sun's changing position throughout the year and the Earth's elliptical orbit.

Environmental and Weather Considerations

Several local factors in Auburn can affect solar production:

• Snow accumulation during Maine's winters can temporarily reduce output until panels clear
• Tree coverage is substantial in the region and can create shading issues
• Occasional heavy cloud cover, particularly during winter months
• Potential for ice storms that could damage equipment

To mitigate these challenges, solar installations in Auburn should incorporate several preventative measures. Panels can be installed at slightly steeper angles than the optimal 38 degrees to help shed snow more effectively. Regular tree maintenance around the array prevents shading issues. Using microinverters or power optimizers helps minimize production losses when partial shading occurs. Additionally, high-quality mounting systems designed for heavy snow loads and potential ice accumulation ensure system durability through harsh Maine winters.

Despite these seasonal challenges, Auburn's strong spring and summer production makes solar viable when properly designed with these local conditions in mind.

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 Auburn, Maine

Seasonal solar PV output for Latitude: 44.0938, Longitude: -70.2368 (Auburn, Maine, 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 Auburn, Maine, United States

To maximize your solar PV system's energy output in Auburn, Maine, United States (Lat/Long 44.0938, -70.2368) 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 Auburn, Maine, 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 Auburn, Maine, 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
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 Auburn, Maine, 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 Auburn, Maine, 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 Auburn, Maine, United States

Auburn, Maine is nestled in a region characterized by gentle rolling hills and valleys, typical of New England's interior landscape. The city sits in Androscoggin County, along the western bank of the Androscoggin River, which has carved a significant valley through the terrain over geological time. This river valley creates a natural lowland corridor that runs roughly northeast to southwest through the area. The topography around Auburn features modest elevation changes, with hills generally ranging between 200-500 feet above sea level. The land gradually rises as one moves westward from the river, with more pronounced hills appearing as you approach the foothills of the White Mountains further to the west. The eastern portions of Auburn, closer to the Androscoggin River, tend to be flatter and less elevated. Several small lakes and ponds dot the landscape surrounding Auburn, including Taylor Pond and Lake Auburn to the north and northwest of the city center. These water bodies occupy natural depressions in the rolling terrain and contribute to the region's varied topography.

Potential Areas for Solar PV Development

When considering large-scale solar photovoltaic (PV) installations near Auburn, several factors related to topography become important. The most suitable areas would generally include: The relatively flat agricultural lands to the west and southwest of Auburn offer promising potential for solar development. These areas feature cleared fields with minimal shading from trees, gentle slopes that can be oriented toward the sun's path, and relatively easy access to existing infrastructure. Former industrial sites or brownfields within and around Auburn present opportunities for solar development without disrupting natural or agricultural lands. These areas are typically already cleared, relatively flat, and often have existing connections to the electrical grid. The slightly elevated hillsides with southern exposures provide naturally advantageous conditions for solar collection. Areas with south-facing slopes between 5-15 degrees can capture more solar radiation throughout the year than completely flat terrain, particularly during winter months when the sun's angle is lower. Areas to avoid would include the steeper slopes found in the more rugged terrain to the west, wetlands associated with the river and various streams, and densely forested regions that would require significant clearing. The immediate floodplain of the Androscoggin River would also pose challenges due to potential flooding risks. The mixture of open agricultural land, gently rolling terrain, and existing cleared areas makes the region around Auburn conducive to solar development, though careful site selection would need to account for local zoning, environmental considerations, and proximity to transmission infrastructure.
