Dracut, Massachusetts, situated in the Northern Temperate Zone at coordinates 42.6582, -71.3058, presents varying conditions for solar PV energy generation throughout the year. The location experiences significant seasonal fluctuations in solar electricity production that are worth understanding for anyone considering solar installation.
Solar panels in Dracut generate their highest output during summer months, producing an average of 5.72 kWh per day for each kilowatt of installed capacity. Spring follows closely behind with 5.37 kWh/day per installed kilowatt. Production drops considerably in autumn to 3.29 kWh/day, while winter sees the lowest generation at just 1.97 kWh/day per kilowatt installed.
For fixed panel installations in this location, the ideal tilt angle to maximize year-round solar production is 37 degrees facing South. This specific angle has been calculated based on the location's latitude and seasonal solar patterns to optimize annual energy harvest.
Seasonal Considerations
The substantial difference between summer and winter production (nearly three times more energy in summer) indicates that Dracut experiences typical New England seasonal variations. The location is most productive for solar generation from late spring through early fall, with May through September likely providing the highest returns on solar investment.
Environmental and Weather Factors
Several environmental factors may impact solar production in Dracut:
- Snow accumulation in winter months can significantly reduce output by covering panels, explaining part of the low winter production figures.
- Deciduous tree coverage, common in Massachusetts, may create seasonal shading issues as trees leaf out in spring and summer.
- New England's variable weather patterns, including frequent cloud cover and precipitation throughout the year, contribute to lower overall production compared to sunnier regions.
Preventative Measures
To maximize solar production in Dracut despite these challenges, consider these installation strategies:
- Install panels at the recommended 37-degree tilt to optimize year-round production
- Use snow-shedding mounting systems that facilitate natural snow removal
- Consider slightly steeper panel angles if winter production is particularly important
- Conduct thorough shade analysis and tree trimming where necessary
- Implement micro-inverters or power optimizers to minimize the impact of partial shading
- Regular panel cleaning, especially after winter storms and during pollen season
While Dracut isn't ideal for solar production compared to sunnier regions, the strong summer and spring performance still makes solar viable, particularly with properly optimized installations that account for local conditions.

Ideally tilt fixed solar panels 37° South in Dracut, United States
To maximize your solar PV system's energy output in Dracut, United States (Lat/Long 42.6582, -71.3058) throughout the year, you should tilt your panels at an angle of 37° 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 Dracut, 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 Dracut, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 26° South in Summer | 47° South in Autumn | 57° 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 Dracut, 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 Dracut, 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 Dracut, United States
Dracut sits in northeastern Massachusetts, just across the Merrimack River from Lowell and approximately 30 miles northwest of Boston. The topography of Dracut and its surrounding areas consists primarily of gently rolling hills, small valleys, and modest elevation changes typical of the New England landscape. The terrain gradually rises from the Merrimack River valley, which forms Dracut's southern border, toward the north. The land contains a mixture of forested areas, open fields, wetlands, and suburban development. Beaver Brook and Spaulding Brook are notable waterways that traverse the town, creating small valleys within the otherwise moderately undulating terrain. The highest elevations in Dracut reach approximately 300-400 feet above sea level, with the most prominent high points located in the northern sections of town near the New Hampshire border.
Solar PV Potential in the Dracut Area
For large-scale solar PV development, several areas near Dracut offer promising characteristics. The most suitable locations would be: The open agricultural lands in northern Dracut and neighboring Pelham, New Hampshire present favorable conditions for solar installations. These areas feature relatively flat terrain with fewer tree stands, reducing the need for extensive clearing and grading. The gentle south-facing slopes that exist in parts of this region would optimize solar exposure throughout the day. Former industrial sites and brownfields around Lowell and southern Dracut could be repurposed for solar development. These areas typically have minimal vegetation, existing access to electrical infrastructure, and flat terrain that requires little preparation for panel installation. The cleared areas along existing utility corridors that run through the region offer linear pathways that are already maintained and free of tall vegetation. These corridors frequently feature accessible terrain and proximity to transmission infrastructure, reducing interconnection costs. Less suitable areas include the wetlands associated with Beaver Brook and other waterways, heavily forested sections that would require significant clearing, and steeply sloped terrain that would complicate construction and potentially create shading issues between panel rows. The moderately hilly nature of the region means that site selection requires careful assessment of slope orientation. South-facing slopes receive more direct sunlight in the northern hemisphere and would yield better performance for fixed-tilt systems. The rolling topography also necessitates consideration of potential shading from nearby hills, especially during winter months when the sun's path is lower in the southern sky.United States solar PV Stats as a country
