Solar PV Analysis of Union, New Jersey, United States
Union, New Jersey, in the United States, offers a moderately favorable location for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this area experiences distinct seasonal variations in solar energy production.
Seasonal Solar Performance
Solar energy output at this location fluctuates significantly across the seasons. Summer stands out as the most productive period, with an impressive daily average of 6.05 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.47 kWh/day. Autumn sees a noticeable decrease to 3.54 kWh/day, while winter experiences the lowest output at 2.18 kWh/day.
The substantial difference between summer and winter production highlights the impact of seasonal changes on solar energy generation in Union. This variation is primarily due to changes in daylight hours and sun angle throughout the year.
Optimal Panel Installation
To maximize year-round solar energy production in Union, fixed solar panels should be installed at a tilt angle of 35 degrees facing south. This optimal angle has been calculated to balance seasonal variations and capture the most sunlight throughout the year.
Environmental and Weather Considerations
While Union's location is generally suitable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:
- Snow accumulation in winter months can temporarily reduce panel output
- Occasional severe weather events, such as hurricanes or nor'easters, may pose risks to solar installations
To mitigate these factors, consider installing panels at a steeper angle to encourage snow sliding off, and ensure robust mounting systems are used to withstand high winds. Regular maintenance and cleaning, especially after snowfall or storms, can help maintain optimal performance.
Despite these challenges, Union's location still offers good potential for solar energy generation, particularly from late spring through early fall. With proper installation and maintenance, solar PV systems can provide a significant contribution to local energy needs throughout the year.
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 Union, New Jersey
Seasonal solar PV output for Latitude: 40.6947, Longitude: -74.2688 (Union, New Jersey, 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 Union, New Jersey, United States
To maximize your solar PV system's energy output in Union, New Jersey, United States (Lat/Long 40.6947, -74.2688) 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 Union, New Jersey, 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 Union, New Jersey, 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 Union, New Jersey, 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 Union, New Jersey, 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 Union, New Jersey, United States
The topography around Union, United States (located at 40.6947° N, 74.2688° W) is characterized by a mix of gently rolling hills and relatively flat areas. This region is part of the larger New Jersey Piedmont, which is a transition zone between the coastal plains to the east and the more rugged Appalachian Mountains to the west.
The area surrounding Union features low-lying terrain with modest elevation changes. The landscape is primarily urban and suburban, with pockets of green spaces and small wooded areas interspersed throughout. The nearby Watchung Mountains, a series of low ridges, provide some topographical variation to the northwest of Union.
To the east of Union, the land becomes increasingly flat as it approaches the coastal areas and wetlands near Newark Bay and the Arthur Kill strait. This gradual flattening of the terrain is typical of the transition from the Piedmont to the Atlantic Coastal Plain.
Regarding areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, there are a few considerations to keep in mind. The ideal locations for solar farms in this region would be:
- Open, flat areas with minimal shading from trees or buildings
- Lands that are not prime agricultural or ecologically sensitive
- Areas with existing infrastructure for power transmission
Given these criteria, some potential areas for large-scale solar PV near Union might include:
- Brownfield sites or former industrial areas that have been remediated
- Large, open spaces such as closed landfills or unused portions of industrial parks
- Expansive rooftops of warehouses or commercial buildings in nearby industrial zones
It's important to note that the densely populated nature of this region may limit the availability of large, contiguous areas suitable for extensive solar farms. As such, distributed solar installations on rooftops and smaller parcels of land may be more feasible in this urban environment. Additionally, any large-scale solar project would need to comply with local zoning regulations and environmental considerations.
