Solar PV Analysis of Passaic, United States
Based on the given data, Passaic in the United States has varying potential for solar energy production throughout the year. During summer and spring, it can produce a decent amount of solar energy with 6.05kWh/day and 5.47kWh/day per kW of installed solar respectively. This is because these seasons generally have longer days and more sunlight, making them ideal for solar power generation.
However, during autumn and winter, the potential for solar energy production decreases significantly to 3.54kWh/day and 2.18kWh/day respectively per kW of installed solar panel due to shorter daylight hours and less intense sunlight.
To maximize year-round production from your solar panels in Passaic, New Jersey, it's recommended to tilt them at an angle of 35 degrees facing South. This allows the panels to capture as much sunlight as possible throughout different times of the day and different seasons.
As far as local factors that could affect solar production at this location are concerned, weather conditions such as heavy snowfall in winter or frequent cloudy days could reduce the amount of sunlight reaching your panels thus reducing their output. Additionally, any tall buildings or trees that cast shadows on your panels would also limit their productivity.
To mitigate these issues:
1) Regular maintenance should be done especially during winter months to clear off any snow buildup on your panels.
2) If possible position your installation where there is minimal shading from nearby structures or vegetation.
3) Use high-quality PV modules which perform better under low light conditions.
4) Consider using tracking systems that follow sun’s path across sky for maximum exposure if budget permits.
Remember though even with these precautions there will still be fluctuations in output based on seasonal changes which are simply part of using a renewable energy source like sun power!
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Passaic
Seasonal solar PV output for Latitude: 40.8565, Longitude: -74.1231 (Passaic, 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 Passaic, United States
To maximize your solar PV system's energy output in Passaic, United States (Lat/Long 40.8565, -74.1231) 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 Passaic, 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 Passaic, 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 | 34° 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 Passaic, 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 Passaic, 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 Passaic, United States
Passaic, United States is located in the state of New Jersey and is characterized by a relatively flat topography. It lies within the Atlantic Coastal Plain with elevations ranging from sea level to approximately 150 feet. The region has a mix of urban, suburban, and some rural landscapes.
For large-scale solar PV installations, areas with open and flat terrains are ideal as they allow for easy installation and maximum sunlight exposure. In the vicinity of Passaic, suitable locations could include industrial zones or brownfield sites that are not currently in use or agricultural lands that are not highly productive.
However, it's important to note that land suitability for solar PV also depends on other factors such as local climate (amount of sunshine), proximity to power grids for easy transmission, land cost and availability, environmental considerations etc.
In terms of sunshine hours which is critical for solar energy production - New Jersey does receive ample sunlight making it suitable for solar power generation. Also worth noting is that NJ has several policies supporting renewable energy development including solar.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
