Willingboro, New Jersey, 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 energy production varies significantly across seasons, with peak performance during summer months and reduced output in winter.
Seasonal Solar Performance
Solar energy production in Willingboro exhibits strong seasonal variations:
- Summer: 6.05 kWh/day per kW installed
- Spring: 5.47 kWh/day per kW installed
- Autumn: 3.54 kWh/day per kW installed
- Winter: 2.18 kWh/day per kW installed
Optimal Panel Installation
For fixed panel installations in Willingboro, the ideal tilt angle to maximize year-round solar production is 35 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, balancing seasonal variations in sun position and intensity.
Environmental and Weather Considerations
While Willingboro's location is generally suitable for solar energy production, there are some environmental and weather factors that could impact performance: 1. Snowfall: New Jersey experiences moderate snowfall in winter, which can temporarily reduce solar panel efficiency. Regular panel cleaning or the installation of snow guards can mitigate this issue. 2. Cloud cover: The region experiences partly cloudy conditions throughout the year, which can intermittently reduce solar output. Using high-efficiency panels and microinverters can help maximize energy production even during cloudy periods. 3. Tree shading: Willingboro has a significant tree population, which could potentially cast shadows on solar panels. Careful site assessment and strategic panel placement can minimize shading issues.
Preventative Measures
To enhance solar energy production in Willingboro, consider the following preventative measures: 1. Install panels at the optimal 35-degree tilt facing South to maximize year-round production. 2. Use high-efficiency panels and microinverters to improve performance during cloudy periods and partial shading conditions. 3. Implement a regular cleaning schedule, especially after snowfall events, to maintain optimal panel efficiency. 4. Conduct a thorough site assessment to identify and mitigate potential shading issues from nearby trees or structures. By addressing these factors, solar installations in Willingboro can achieve improved energy production and long-term performance.

Solar output per kW of installed solar PV by season in Willingboro
Seasonal solar PV output for Latitude: 40.0296, Longitude: -74.8834 (Willingboro, 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 Willingboro, United States
To maximize your solar PV system's energy output in Willingboro, United States (Lat/Long 40.0296, -74.8834) 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 Willingboro, 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 Willingboro, 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 | 44° South in Autumn | 55° 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 Willingboro, 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 Willingboro, 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 Willingboro, United States
The topography around Willingboro, New Jersey, is generally characterized by flat to gently rolling terrain. This area is part of the Atlantic Coastal Plain, which extends along the eastern seaboard of the United States. The landscape is predominantly low-lying, with elevations typically ranging from just a few feet above sea level to around 100 feet in some areas.
Willingboro itself sits at an average elevation of about 40 feet above sea level. The surrounding region features a mix of suburban developments, agricultural lands, and patches of woodland. The nearby Delaware River, which flows to the west of Willingboro, has shaped much of the local topography over time, creating a broad, flat floodplain along its banks.
To the east of Willingboro, the terrain remains relatively flat as it extends towards the New Jersey Pine Barrens. This vast forested area is known for its sandy soil and subtle changes in elevation. To the north and south, the landscape continues to be mostly level, with occasional gentle hills and shallow valleys formed by small streams and creeks.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors come into play. Ideally, solar farms require large, open spaces with minimal shading and relatively flat terrain. Based on these criteria, some potentially suitable areas near Willingboro might include:
- Former agricultural lands or fallow fields to the east and southeast of Willingboro, where there are fewer dense urban developments.
- Open spaces along the outskirts of nearby towns and townships, such as Westampton, Eastampton, or Mount Laurel, where zoning laws may be more accommodating to large-scale solar projects.
- Brownfield sites or former industrial areas in the broader Burlington County region, which could be repurposed for solar energy production.
- Large, flat rooftops of commercial or industrial buildings in nearby business parks or shopping centers, although these would be smaller in scale compared to ground-mounted solar farms.
It's important to note that while the topography in this region is generally favorable for solar PV installations, other factors such as local regulations, grid connectivity, and environmental considerations would also need to be taken into account when determining the most suitable locations for large-scale solar projects.
