Madawaska, Maine, located in the Northern Temperate Zone of the United States, presents varying conditions for solar energy generation throughout the year. The town's geographical position at latitude 47.3332 and longitude -68.3316 influences its solar potential significantly.
Seasonal Solar Production
Solar energy production in Madawaska fluctuates considerably across seasons. Summer stands out as the most productive period, with an average daily output of 5.95 kWh per kW of installed solar capacity. Spring follows closely, yielding 5.05 kWh/day. However, production drops dramatically during autumn and winter, with outputs of 2.72 kWh/day and 1.63 kWh/day, respectively.
Optimal Times for Solar Generation
The most favorable months for solar energy production in Madawaska are from late spring through early fall. This period, roughly from May to September, offers longer daylight hours and generally clearer skies, maximizing solar panel efficiency. The summer solstice in June typically marks the peak of solar potential.
Panel Installation Considerations
For fixed panel installations in Madawaska, the ideal tilt angle to maximize year-round production is 40 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the sun's varying positions across seasons.
Environmental and Weather Factors
Several factors can impede solar production in Madawaska:
- Snow accumulation in winter months can significantly reduce panel efficiency
- Frequent cloud cover, especially during winter and early spring
- Short daylight hours in winter, with some days having less than 9 hours of sunlight
Preventative Measures
To mitigate these challenges and ensure greater energy production, consider the following measures when installing solar panels:
1. Use snow-shedding designs or install panels at a steeper angle to facilitate snow sliding off.
2. Implement regular maintenance schedules, including snow removal during winter months.
3. Consider bifacial panels to capture reflected light from snow, potentially increasing winter production.
4. Use high-efficiency panels that perform better in low-light conditions to maximize output during cloudy periods.
5. Incorporate a battery storage system to balance out the seasonal variations in energy production.
While Madawaska's location presents challenges for year-round solar energy production, particularly in winter, proper planning and installation techniques can help maximize the system's efficiency and overall energy output.

Ideally tilt fixed solar panels 40° South in Madawaska, United States
To maximize your solar PV system's energy output in Madawaska, United States (Lat/Long 47.3332, -68.3316) throughout the year, you should tilt your panels at an angle of 40° 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 Madawaska, 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 Madawaska, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 51° South in Autumn | 61° South in Winter | 39° 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 Madawaska, 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 Madawaska, 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 Madawaska, United States
The area around Madawaska, located in northern Maine near the Canadian border, features a diverse and picturesque topography characteristic of the Appalachian region. The landscape is dominated by gently rolling hills, low mountains, and numerous water bodies, creating a beautiful tapestry of natural features.
The town of Madawaska itself sits in a relatively flat area along the Saint John River, which forms the border between the United States and Canada. As you move away from the river, the terrain becomes more varied. To the south and west, the land gradually rises into the foothills of the Appalachian Mountains, with elevations increasing as you travel further from the town.
The region is dotted with numerous lakes, ponds, and streams, which are remnants of glacial activity from thousands of years ago. These water bodies contribute to the area's appeal for outdoor enthusiasts and provide important habitats for local wildlife. The forested areas, primarily consisting of mixed hardwoods and conifers, cover much of the landscape, adding to the region's natural beauty and ecological diversity.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few factors to consider. Ideally, solar farms require relatively flat or gently sloping land with good exposure to sunlight throughout the day. Given the topography of the Madawaska area, the most suitable locations for solar PV would likely be:
- The flatter areas along the Saint John River valley, where there is less shadowing from hills and mountains.
- Cleared agricultural land or former farmland in the surrounding rural areas, which often provide open spaces with minimal obstructions.
- South-facing slopes of gentle hills, which can maximize exposure to sunlight throughout the day.
However, it's important to note that the northern location of Madawaska means it receives less direct sunlight compared to more southern regions, which could impact the overall efficiency of solar installations. Additionally, the area's heavy forest cover and the presence of numerous water bodies may limit the availability of large, contiguous areas suitable for extensive solar farms. Any potential solar PV project would need to carefully balance these factors with environmental considerations and local land use regulations.
