Buxton, Maine, located in the Northern Temperate Zone at latitude 43.6401 and longitude -70.5213, offers varying potential for solar PV energy generation throughout the year. The location experiences significant seasonal fluctuations in solar electricity production, with the highest output occurring during summer months.
Seasonal Solar Production
Solar panels in Buxton generate their maximum electricity during summer, producing approximately 5.76 kWh per day for each kilowatt of installed capacity. Spring follows closely behind with 5.32 kWh/day per kW installed. Production decreases substantially in autumn to 3.24 kWh/day, while winter sees the lowest output at just 1.90 kWh/day per kW of installed solar capacity.
This pattern clearly indicates that Buxton's solar potential peaks during the warmer months of late spring through early fall, with a significant drop during the winter season. Homeowners and businesses considering solar installations should account for these seasonal variations when planning system size to meet year-round energy needs.
Optimal Panel Installation
For fixed solar panel installations in Buxton, the ideal tilt angle to maximize year-round energy production is 38 degrees facing South. This angle has been calculated by analyzing the daily solar elevation angles at this specific latitude, weighted by the solar irradiance potential throughout the year.
Environmental and Weather Considerations
Several significant factors could impede solar production in Buxton:
- Snow accumulation during Maine's winters can temporarily reduce or eliminate production if panels become covered
- Frequent cloud cover, particularly during winter months
- Tree coverage and shading issues common in Maine's forested regions
- Potential for ice buildup during winter storms
Preventative Measures
To maximize solar production despite these challenges, consider implementing these strategies:
- Install panels at the recommended 38-degree angle to promote natural snow sliding
- Ensure panels are mounted high enough to avoid snow drifts
- Consider periodic manual snow removal when necessary
- Conduct thorough shade analysis before installation to minimize tree shading
- Use microinverters or power optimizers to minimize the impact of partial shading
- Select solar panels with anti-reflective coatings and high low-light performance specifications
With proper installation techniques addressing these local factors, a solar PV system in Buxton can still provide substantial energy production, particularly during the productive spring through fall seasons, while continuing to generate some electricity even during the less favorable winter months.

Ideally tilt fixed solar panels 38° South in Buxton, United States
To maximize your solar PV system's energy output in Buxton, United States (Lat/Long 43.6401, -70.5213) 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 Buxton, 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 Buxton, 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 | 58° South in Winter | 36° 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 Buxton, 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 Buxton, 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 Buxton, United States
The topography around Buxton, Maine presents a gentle yet varied landscape characteristic of southern Maine's inland areas. Situated in York County, approximately 20 miles west of Portland, Buxton occupies a transitional zone between coastal lowlands and the foothills of the White Mountains. The terrain consists primarily of rolling hills with moderate elevation changes, typically ranging between 100 and 400 feet above sea level. The Saco River forms a significant natural feature as it winds through the eastern portion of Buxton, creating fertile floodplains and occasional steep embankments along its course. This river valley introduces some of the more dramatic topographical elements in an otherwise gently undulating landscape. Several smaller streams and brooks further dissect the terrain, creating small valleys throughout the area.
Forest Cover and Open Spaces
Mixed forests dominate much of the landscape around Buxton, with northern hardwoods and eastern white pine being particularly common. These wooded areas frequently alternate with cleared agricultural fields, creating a patchwork pattern typical of rural New England. The forest density varies, with some areas featuring dense woodland while others maintain more open canopies. Open spaces in the region include agricultural fields, meadows, and areas cleared for residential or commercial development. Historical land use patterns have created distinct zones where forests were cleared generations ago, resulting in relatively flat, open expanses that interrupt the otherwise forested landscape.Potential for Solar Development
When considering areas near Buxton suitable for large-scale solar photovoltaic installations, several factors related to topography become relevant. The most promising locations would be: Former agricultural lands with southern exposure represent prime candidates for solar development. These areas typically feature cleared, relatively flat terrain with minimal shading from surrounding forests. Several such locations exist in the western and northwestern portions of Buxton, particularly in areas where farming activities have diminished in recent decades. Gently sloping hillsides with southern or southeastern aspects also offer excellent potential for solar installations. These locations benefit from favorable sun angles throughout the day and seasons. The northern portions of Buxton contain several hills with ideal southern exposures that could accommodate substantial solar arrays while minimizing visual impact from populated areas. Areas with well-drained soils, typically found on slight elevations rather than in valley bottoms, would reduce construction challenges and maintenance issues. The glacial till soils common throughout much of the region provide reasonably good drainage on higher ground, making these locations technically advantageous for solar infrastructure. Locations with existing access to transmission infrastructure would minimize development costs. Several utility corridors traverse the Buxton area, creating opportunities for solar development adjacent to existing rights-of-way where land has already been partially cleared.Topographical Challenges
Despite these opportunities, certain topographical features around Buxton present challenges for large-scale solar development. The Saco River floodplain, while flat and often cleared, faces periodic flooding risks that would complicate solar installations. Similarly, the numerous wetland areas scattered throughout the region would require careful avoidance or mitigation strategies. Areas with steep slopes, particularly those exceeding 15% grade, would increase construction costs and erosion risks. Such terrain is more common in the eastern portions of Buxton and along stream valleys. The mixed forest cover, while aesthetically pleasing and ecologically valuable, creates potential shading issues that would require careful site selection or more extensive clearing, raising both economic and environmental considerations. In conclusion, the topography around Buxton offers moderate potential for large-scale solar development, with the most promising sites being former agricultural lands and gently sloping hillsides with southern exposure, particularly in the western and northern sections of the town. These areas combine favorable terrain with practical development considerations while working within the constraints of the region's rolling, partially forested landscape.United States solar PV Stats as a country
