Pittsfield, Maine, located in the Northern Temperate Zone, presents a mixed picture for year-round solar energy generation. This location experiences significant seasonal variations in solar output, which impact the overall efficiency of photovoltaic (PV) systems throughout the year.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Pittsfield, with an impressive daily output of 5.79 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.41 kWh/day. However, the performance drops considerably during autumn and winter, with outputs of 3.19 kWh/day and 2.01 kWh/day, respectively.
These figures indicate that Pittsfield experiences a significant solar energy potential during the warmer months, making it an attractive location for PV installations. The extended daylight hours and higher sun angles during summer and spring contribute to this increased productivity.
Optimal Panel Positioning
To maximize year-round solar energy production in Pittsfield, fixed solar panels should be tilted at a 39-degree angle facing south. This optimal angle takes into account the location's latitude and seasonal variations in sun position, ensuring the best possible energy capture throughout the year.
Environmental and Weather Considerations
While Pittsfield offers good solar potential, there are some environmental factors that could impact solar production:
- Snow accumulation during winter months can temporarily reduce panel efficiency.
- Cloudy weather, particularly common in late autumn and winter, may decrease solar output.
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off and using high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal, can also help maintain optimal performance.
Conclusion
Despite the challenges posed by seasonal variations and weather conditions, Pittsfield, Maine, remains a viable location for solar PV installations. The strong performance during summer and spring months can offset the reduced output in autumn and winter, making it a worthwhile investment for those looking to harness renewable energy in this region.

Solar output per kW of installed solar PV by season in Pittsfield, Maine
Seasonal solar PV output for Latitude: 44.7907, Longitude: -69.3842 (Pittsfield, 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 39° South in Pittsfield, Maine, United States
To maximize your solar PV system's energy output in Pittsfield, Maine, United States (Lat/Long 44.7907, -69.3842) 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 Pittsfield, 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 Pittsfield, Maine, 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 | 49° South in Autumn | 59° 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 Pittsfield, 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 Pittsfield, Maine, 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 Pittsfield, Maine, United States
The area around Pittsfield, Maine, is characterized by a diverse and gently rolling landscape typical of central Maine. This region is part of the New England Upland, which features a mix of low hills, shallow valleys, and numerous small lakes and ponds scattered throughout the terrain.
The topography in and around Pittsfield is relatively modest in terms of elevation changes. The land gradually rises from the southeast to the northwest, with elevations ranging from about 200 feet to 500 feet above sea level. The countryside is a patchwork of open fields, farmland, and forested areas, interspersed with small streams and rivers that have carved shallow valleys over time.
To the east of Pittsfield lies the Sebasticook River, which flows southward and has shaped much of the local landscape. The river valley provides some of the flatter areas in the region, with gentle slopes leading down to the water's edge. To the west and northwest, the terrain becomes slightly more pronounced, with rolling hills becoming more frequent and pronounced.
For large-scale solar PV installations, the most suitable areas nearby would likely be found in the open, gently sloping fields to the south and southeast of Pittsfield. These areas offer several advantages for solar energy production:
- They tend to have fewer trees and obstructions that could cast shadows on solar panels.
- The gradual slopes often face south or southeast, which is ideal for maximizing sun exposure throughout the day.
- These areas are generally easily accessible, which is important for construction and maintenance of solar facilities.
- The land is often already cleared for agriculture, reducing the need for extensive site preparation.
While the hills to the northwest might offer some elevated positions for solar arrays, the increased forest cover and more varied terrain could make large-scale installations more challenging and costly to develop. The river valley areas, while flat, may be subject to more fog or mist, potentially reducing solar efficiency.
It's worth noting that any specific site selection for solar PV would require detailed local assessments, including soil stability, proximity to power infrastructure, and environmental impact studies. Additionally, local zoning laws and land use regulations would need to be considered before any large-scale solar project could be implemented in the Pittsfield area.
