Uniondale, New York, located in the Northern Temperate Zone, offers a moderately favorable environment for solar PV energy generation throughout the year. The location's potential for solar power production varies significantly across seasons, with peak performance during summer months and reduced output in winter.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive daily output of 6.15 kWh per kW of installed solar capacity. Spring follows closely, generating 5.69 kWh/day. Autumn sees a noticeable decrease to 3.69 kWh/day, while winter experiences the lowest production at 2.20 kWh/day.

The substantial variation between seasons highlights the importance of considering year-round performance when planning solar installations in Uniondale. While summer and spring offer excellent generation potential, the significant drop in autumn and winter output may necessitate additional energy sources or storage solutions for consistent year-round power supply.

Optimal Panel Positioning

To maximize year-round solar energy production in Uniondale, fixed solar panels should be installed at a 35-degree tilt angle facing south. This orientation ensures optimal exposure to sunlight throughout the year, balancing the varying sun angles across seasons.

Environmental and Weather Considerations

Uniondale's climate presents some challenges for solar energy production. The area experiences occasional severe weather, including hurricanes and nor'easters, which can potentially damage solar installations. Heavy snowfall in winter may temporarily reduce panel efficiency if not promptly cleared.

To mitigate these risks, solar installations in Uniondale should incorporate robust mounting systems capable of withstanding high winds. Additionally, panels should be installed with sufficient elevation and tilt to facilitate natural snow shedding. Regular maintenance, including snow removal during winter months, can help ensure consistent energy production year-round.

Despite these challenges, Uniondale's location offers a good balance of solar potential, particularly during the warmer months. With proper planning and preventative measures, solar PV systems can provide a significant and reliable source of renewable energy for the community.

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

Seasonal solar PV output for Latitude: 40.7047, Longitude: -73.5933 (Uniondale, 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 Uniondale, United States

To maximize your solar PV system's energy output in Uniondale, United States (Lat/Long 40.7047, -73.5933) 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 Uniondale, 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 Uniondale, 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 Uniondale, 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 Uniondale, 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 Uniondale, United States

The area around Uniondale, located in Nassau County, New York, is characterized by a relatively flat topography typical of Long Island's coastal plain. This region, part of the larger Atlantic Coastal Plain, features gently rolling terrain with minimal elevation changes. The landscape is predominantly suburban, with a mix of residential neighborhoods, commercial areas, and scattered green spaces. The topography in and around Uniondale is generally low-lying, with elevations ranging from near sea level to approximately 100 feet above sea level. The terrain gradually slopes upward as you move north from the southern coast of Long Island. This gentle incline is barely noticeable in most areas, creating a mostly level surface throughout the region.

Natural Features

While the area is largely developed, there are some natural features that contribute to the local topography. Small streams and drainage channels crisscross the landscape, though many have been modified or channelized due to urban development. Scattered ponds and small lakes, both natural and man-made, dot the region, providing some variation to the otherwise flat terrain.

Urban Influence on Topography

The extensive urbanization of the area has significantly altered the natural topography. Roads, buildings, and other infrastructure have leveled much of the land, creating an even more uniform surface. Parks and golf courses in the vicinity often represent some of the few areas where the original contours of the land are still somewhat visible.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The flat terrain of the region is generally favorable for solar installations, as it minimizes the need for extensive land preparation. However, the dense suburban development in and immediately around Uniondale presents challenges for finding suitable large, open spaces. Areas that might be more appropriate for large-scale solar PV projects would likely be found further east on Long Island, where there is less dense development and more open land. The flatter, more rural areas of eastern Suffolk County, for instance, could potentially offer more suitable locations for expansive solar farms. Alternatively, large rooftops of commercial and industrial buildings in the broader Long Island region could be considered for solar PV installations. These structures often provide vast, unobstructed surfaces ideal for solar panels, without requiring additional land use. It's important to note that any large-scale solar project in this region would need to carefully consider local zoning regulations, environmental impacts, and community concerns, given the densely populated nature of Long Island and its limited open space.

United States solar PV Stats as a country
