Roosevelt, New York, United States offers moderate solar energy potential for year-round electricity generation through solar photovoltaic systems. Located in the Northern Temperate Zone at coordinates 40.677° North, -73.587° West, this Long Island community experiences significant seasonal variation in solar output.

Seasonal Solar Performance

The location shows typical temperate zone patterns with strong summer production and reduced winter output. Summer delivers the highest energy generation at 6.14 kWh per day per kW of installed solar capacity, making it the prime season for solar electricity production. Spring follows as the second-best performing season at 5.64 kWh per day per kW, offering nearly as much energy generation as summer months. Autumn production drops to 3.62 kWh per day per kW, while winter represents the lowest output period at just 2.11 kWh per day per kW of installed capacity. This seasonal variation is normal for northeastern United States locations and should be factored into energy planning.

Optimal Installation Configuration

For fixed panel installations in Roosevelt, the ideal tilt angle is 35 degrees facing south to maximize total year-round solar production. This angle balances the sun's changing position throughout the seasons to capture the most energy over the entire year.

Environmental and Weather Challenges

Several local factors can significantly impact solar production in Roosevelt and require careful consideration during installation planning. Snow accumulation during winter months poses the primary seasonal challenge. Heavy snow can completely block solar panels, reducing output to zero until cleared. Long Island typically receives 20-30 inches of annual snowfall, with potential for occasional major storms dumping much larger amounts. The coastal proximity brings salt air exposure, which can corrode mounting hardware and electrical connections over time if not properly protected. This marine environment accelerates corrosion compared to inland locations. Roosevelt's location puts it in the path of nor'easter storms and occasional hurricanes, bringing high winds, heavy precipitation, and potential debris impacts. These weather events can damage panels or mounting systems if not properly secured. Tree coverage and urban development in the area can create shading issues, particularly during winter months when the sun angle is lower. Even partial shading can dramatically reduce panel output.

Preventative Installation Measures

Several strategies can help maximize solar production despite these environmental challenges:

• Install panels at steeper angles (40-45 degrees) to promote natural snow shedding, though this reduces summer efficiency slightly
• Use marine-grade mounting hardware and electrical components rated for salt air exposure
• Apply anti-corrosion coatings to all metal components and ensure proper grounding systems
• Design mounting systems to withstand wind loads up to 150 mph for hurricane resistance
• Install panels high enough to clear typical snow accumulation levels

Regular maintenance becomes crucial in this environment. Schedule professional cleaning and inspection twice yearly, with additional checks after major storms. Keep panels clear of snow, leaves, and debris that can block sunlight. Proper site assessment before installation helps identify and mitigate shading issues from nearby trees or structures. Strategic placement and possible tree trimming can preserve solar access throughout the year. Despite these challenges, Roosevelt's solar potential remains viable for homeowners and businesses willing to invest in quality installation and maintenance practices.

Solar output per kW of installed solar PV by season in Roosevelt

Seasonal solar PV output for Latitude: 40.677, Longitude: -73.587 (Roosevelt, 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 35° South in Roosevelt, United States

To maximize your solar PV system's energy output in Roosevelt, United States (Lat/Long 40.677, -73.587) throughout the year, you should tilt your panels at an angle of 35° 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 Roosevelt, 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 Roosevelt, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
24° South in Summer	45° South in Autumn	56° South in Winter	33° 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 Roosevelt, 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 Roosevelt, 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 Roosevelt, United States

Topography Around Roosevelt, New York

Roosevelt is located in Nassau County on Long Island, New York, positioned in a relatively flat coastal plain region. The area sits at a low elevation, generally ranging from sea level to approximately 100 feet above sea level. This part of Long Island was shaped by glacial activity during the last ice age, resulting in gently rolling terrain with minimal elevation changes across most of the landscape.

The topography consists primarily of glacial outwash plains and terminal moraine deposits, creating a mix of sandy soils and gentle undulations. The terrain slopes very gradually toward the Atlantic Ocean to the south and Long Island Sound to the north. Most of the land around Roosevelt features modest hills and shallow valleys, with no significant mountains or steep terrain that would create substantial shading issues for solar installations.

The surrounding area is predominantly suburban and residential, interspersed with commercial developments, parks, and some remaining agricultural land further east. The relatively flat nature of the region, combined with its coastal location, means there are few natural obstructions to solar exposure from topographical features.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations in the Roosevelt area would be the flatter, more open spaces that currently remain undeveloped or are used for agriculture. These areas typically offer the best combination of minimal shading, adequate space for solar arrays, and fewer zoning complications compared to densely populated residential zones.

Agricultural areas and open fields in the eastern portions of Nassau County and western Suffolk County present excellent opportunities for solar development. These locations benefit from the region's naturally flat topography while offering sufficient acreage for meaningful solar installations. The gentle, south-facing slopes found throughout the area are particularly well-suited for optimal solar panel positioning.

Former industrial sites and brownfields in the region also represent prime candidates for solar development. These areas often have existing electrical infrastructure nearby and fewer environmental concerns related to disrupting natural habitats or productive farmland. The flat, previously developed nature of these sites makes them ideal for large solar arrays without the need for extensive grading or terrain modification.

Coastal areas with minimal development, particularly those with southern exposure and protection from salt spray, could also serve as excellent locations for solar installations. The open nature of these areas, combined with the region's generally flat coastal plain topography, provides ideal conditions for capturing solar energy without obstruction from hills, mountains, or dense vegetation.
