Lakeville, Massachusetts presents a moderately good location for year-round solar energy generation, though with significant seasonal variations typical of the Northern Temperate Zone climate.
Seasonal Solar Performance
The solar energy output at this location shows strong seasonal patterns. Summer provides the highest production at 6.08 kWh per day per kW of installed solar capacity, making it the peak generation season. Spring follows closely behind with 5.72 kWh per day per kW, offering nearly comparable output levels. Autumn production drops considerably to 3.57 kWh per day per kW, while winter represents the most challenging period with only 2.04 kWh per day per kW. This winter figure is approximately one-third of summer production, reflecting the typical challenges of solar generation in New England's climate. For optimal year-round performance, fixed solar panels at this location should be tilted at 36 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's changing position throughout the seasons.Local Factors Affecting Solar Production
Several environmental and weather factors in Lakeville could significantly impact solar energy generation:- Snow accumulation: Heavy winter snowfall can completely block solar panels for days or weeks
- Coastal moisture and fog: Being relatively close to the Atlantic coast, marine air can create foggy conditions that reduce solar irradiance
- Deciduous tree coverage: The heavily forested New England landscape means seasonal shading from nearby trees
- Ice storms: Winter ice formation can damage panels or mounting systems
Preventative Installation Measures
To maximize solar production despite these challenges, several installation strategies prove effective. Mounting panels at the recommended 36-degree tilt naturally helps snow slide off more easily than flatter installations. Installing panels with adequate spacing between rows prevents snow from one panel casting shadows on panels behind it. Careful site selection away from large deciduous trees, particularly those to the south and west of the installation, prevents seasonal shading issues. Where tree removal isn't possible, professional shade analysis can optimize panel placement. Using high-quality mounting systems rated for New England's freeze-thaw cycles and potential ice loading ensures long-term structural integrity. Some installers also recommend slightly higher mounting heights to account for potential snow accumulation at ground level. Regular maintenance becomes particularly important, including post-storm inspections and occasional snow removal during extended periods of heavy accumulation, though panels often self-clear due to their smooth surface and the recommended tilt angle.Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Lakeville, Massachusetts
Seasonal solar PV output for Latitude: 41.8363, Longitude: -70.9607 (Lakeville, Massachusetts, 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 36° South in Lakeville, Massachusetts, United States
To maximize your solar PV system's energy output in Lakeville, Massachusetts, United States (Lat/Long 41.8363, -70.9607) throughout the year, you should tilt your panels at an angle of 36° 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 Lakeville, Massachusetts, 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 Lakeville, Massachusetts, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 46° South in Autumn | 56° South in Winter | 35° 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.

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 Lakeville, Massachusetts, United States
Lakeville, Massachusetts sits in the southeastern portion of the state, characterized by gently rolling terrain typical of the Atlantic Coastal Plain region. The landscape features modest elevation changes with most areas ranging from sea level to approximately 200 feet above sea level. This relatively flat to gently undulating topography creates favorable conditions for large-scale solar installations, as steep slopes and dramatic elevation changes that could complicate construction are largely absent from the area.
The region displays a mixed landscape of agricultural fields, woodlands, and wetland areas. Open agricultural land dominates much of the surrounding countryside, with cranberry bogs being particularly prominent given the area's position within the historic cranberry-growing region of southeastern Massachusetts. These cleared agricultural areas often present ideal opportunities for solar development due to their existing open nature and generally level terrain.
Optimal Solar Development Areas
The most suitable locations for large-scale solar photovoltaic installations around Lakeville would be the expansive agricultural fields that stretch across the region. These areas offer several advantages including minimal tree clearing requirements, relatively level ground that reduces grading costs, and existing access roads that can facilitate construction and maintenance activities. The agricultural fields south and west of Lakeville center appear particularly well-suited, as they combine favorable topography with sufficient size to accommodate utility-scale solar arrays.
Former agricultural land that has been taken out of active production also presents excellent opportunities. These areas maintain the beneficial characteristics of cleared, level terrain while potentially facing fewer regulatory hurdles related to active farming operations. The sandy soils common throughout the region, while sometimes challenging for agriculture, actually provide good drainage characteristics that benefit solar installations by reducing issues with standing water.
Geographical Considerations
The area benefits from its position away from the immediate coastal zone, which helps avoid some of the more stringent environmental regulations associated with coastal development while still maintaining the relatively mild climate of southeastern Massachusetts. The landscape is intersected by several small streams and seasonal waterways, but these features are generally well-defined and can be easily avoided during site planning.
Wooded areas, while abundant throughout the region, would be less suitable for solar development due to the environmental impact and cost associated with clearing mature forest. However, areas where forests have been previously harvested or naturally cleared present potential opportunities, particularly if they maintain the favorable flat to gently sloping characteristics of the broader region.
The proximity to existing electrical infrastructure, including transmission lines that serve the greater southeastern Massachusetts region, enhances the viability of solar development in many of these areas. The relatively stable geology of the region, consisting primarily of glacial deposits over bedrock, provides suitable foundation conditions for solar mounting systems without the complications that might arise in areas with more challenging subsurface conditions.
