Windsor, Maine, in the United States, offers a varied solar energy production profile throughout the year, with significant seasonal fluctuations. Located in the Northern Temperate Zone, this location experiences distinct seasonal changes that directly impact solar electricity generation.

Solar panels in Windsor can produce an average of 5.76 kWh per day for each kilowatt installed during summer months, making this the peak production season. Spring follows closely with 5.36 kWh/day per installed kilowatt. Production decreases substantially during autumn to 3.13 kWh/day, and reaches its lowest point in winter with just 1.95 kWh/day per kilowatt installed.

Optimal Panel Positioning

For fixed solar panel installations in Windsor, the ideal angle to maximize year-round energy production is 38 degrees tilted toward the South. This specific angle has been calculated to optimize annual solar collection based on Windsor's geographic position and seasonal sun paths.

Seasonal Considerations

The substantial difference between summer and winter production rates (nearly a 3:1 ratio) indicates that Windsor experiences significant seasonal variability. Summer and spring represent prime solar harvesting periods, while autumn and particularly winter months will see much lower generation. This seasonal pattern is important to consider when planning for annual energy needs.

Environmental Factors and Mitigation

Several environmental factors in Windsor may affect solar production. Snow accumulation during Maine winters can significantly reduce output by covering panels. Installing panels at the recommended 38-degree tilt helps facilitate snow sliding off, while snow removal systems or periodic manual clearing may be necessary during heavy snowfall periods.

Tree coverage is another consideration in this heavily forested state. Proper site assessment to minimize shading from surrounding trees, especially on the southern exposure, is essential. Strategic tree trimming or positioning panels away from tall growth can maximize production.

Windsor's location also experiences occasional ice storms, which can damage equipment and block sunlight. Using durable, weather-resistant panels rated for harsh conditions and installing ice guards can help protect the system during freezing precipitation events.

Despite these challenges, with proper installation techniques and maintenance practices, solar energy remains a viable renewable energy option for Windsor residents, particularly during the productive spring and summer months.

Solar output per kW of installed solar PV by season in Windsor, Maine

Seasonal solar PV output for Latitude: 44.2982, Longitude: -69.5827 (Windsor, 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 Windsor, Maine, United States

To maximize your solar PV system's energy output in Windsor, Maine, United States (Lat/Long 44.2982, -69.5827) 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 Windsor, 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 Windsor, 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	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 Windsor, 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 Windsor, 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 Windsor, Maine, United States

The topography around Windsor, Maine, nestled in Kennebec County, is characterized by gently rolling hills and shallow valleys typical of central Maine's landscape. This region sits within the Kennebec River watershed, with elevations generally ranging between 200-500 feet above sea level. The terrain was largely shaped by glacial activity during the last ice age, resulting in a mixture of modest hills, small wetland areas, and scattered ponds. Windsor's landscape features a blend of open fields, mixed woodlands dominated by pine, maple, and oak trees, and small agricultural areas. The topography is neither mountainous nor completely flat, but rather pleasantly undulating with gradual slopes. Several small streams and brooks traverse the area, eventually feeding into the Kennebec River system.

Solar Potential in the Windsor Area

The most suitable areas for large-scale solar PV development near Windsor would be the open, cleared lands that face south or southwest. Former agricultural fields or pastures that have minimal shading from tree lines offer particularly good potential. These areas typically have the necessary exposure to maximize solar energy collection throughout the day. Several specific areas around Windsor present promising opportunities for solar development: The cleared upland areas north and northeast of Windsor, extending toward Augusta, feature relatively flat terrain with good southern exposure. These locations often have existing access to roadways and potential grid connection points, making them logistically favorable for solar installations. The agricultural zones to the south and southeast of Windsor also demonstrate favorable topography for solar arrays. These areas typically have already been cleared of trees and have minimal slope issues that might otherwise complicate construction or optimal panel orientation. Areas along Route 17 and Route 32 corridors contain numerous parcels with the right combination of open space, suitable grade, and proximity to existing electrical infrastructure. These locations would minimize the need for extensive new transmission lines or major site preparation. It's worth noting that while Windsor's topography is generally favorable for solar development, site-specific assessments would still be necessary. Factors such as local wetlands, soil conditions, and existing land use restrictions would need careful evaluation before proceeding with any large-scale installation. The modest hills in the region rarely present steep slopes that would make solar construction prohibitively difficult, though careful site selection is still important to avoid north-facing slopes or heavily wooded areas that would require significant clearing.
