Irving, New York, located in the Northern Temperate Zone at coordinates 42.5676, -79.1128, presents a moderately favorable location for solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The solar energy output at this location varies dramatically throughout the year. Summer provides the strongest performance at 6.41 kWh per day per kW of installed solar capacity, making it an excellent time for solar generation. Spring follows as the second-best season with 5.34 kWh per day per kW, offering substantial energy production as daylight hours increase and weather improves. Autumn sees a notable decline to 3.16 kWh per day per kW as the region transitions toward winter conditions. Winter presents the most challenging period for solar generation, dropping to just 1.76 kWh per day per kW of installed capacity, representing less than one-third of summer production levels.

Optimal Installation Configuration

For maximum year-round energy production at Irving, New York, solar panels should be installed at a fixed tilt angle of 36 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and weighting for daily solar potential based on irradiance data.

Local Environmental Challenges

Several significant environmental and weather factors in this region can impede solar production and require careful consideration during installation:

• Heavy snow accumulation: Irving's location in western New York places it in a major snow belt region, particularly affected by lake-effect snow from nearby Lake Erie
• Ice formation: Winter conditions frequently create ice buildup on panels, blocking sunlight penetration
• Frequent cloud cover: The region experiences substantial overcast conditions, especially during fall and winter months
• High humidity and precipitation: The area receives significant rainfall and experiences high humidity levels that can affect equipment performance

Preventative Installation Measures

To maximize solar energy production despite these challenges, several installation strategies prove essential: Installing panels at the recommended 36-degree tilt angle serves a dual purpose - it not only optimizes sun exposure but also helps snow slide off more easily rather than accumulating on panel surfaces. Steeper angles can be considered in areas with particularly heavy snowfall, though this may slightly reduce optimal sun exposure. Selecting high-quality panels with anti-reflective coatings and smooth surfaces helps minimize snow and ice adhesion. Some installers also recommend dark-colored mounting systems that absorb heat and assist with snow melting around panel edges. Proper spacing between panel rows becomes crucial to prevent shading when snow builds up on lower panels. Additionally, ensuring adequate structural support for mounting systems accounts for the extra weight of snow and ice accumulation. Installing micro-inverters or power optimizers rather than string inverters helps maintain energy production when some panels are partially covered by snow or debris, as these systems allow each panel to operate independently rather than being limited by the lowest-performing panel in a series. Regular maintenance scheduling becomes particularly important, with plans for safe snow removal when accumulation is excessive and periodic cleaning to address dust, pollen, and other debris that can accumulate on panel surfaces throughout the year.

Solar output per kW of installed solar PV by season in Irving, New York

Seasonal solar PV output for Latitude: 42.5676, Longitude: -79.1128 (Irving, New York, 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 36° South in Irving, New York, United States

To maximize your solar PV system's energy output in Irving, New York, United States (Lat/Long 42.5676, -79.1128) throughout the year, you should tilt your panels at an angle of 36° 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 Irving, New York, 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 Irving, New York, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
26° South in Summer	46° South in Autumn	57° South in Winter	35° 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.

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 Irving, New York, United States

Topographical Features of the Irving Region

The area surrounding Irving in western New York State is characterized by gently rolling hills and relatively modest elevation changes typical of the Appalachian Plateau region. This landscape sits at approximately 1,400 feet above sea level, with the terrain gradually sloping toward the northwest in the direction of Lake Erie, which lies roughly 20 miles to the north. The topography consists primarily of agricultural land interspersed with woodlands, creating a patchwork of open fields and forested areas across the countryside. The region's geological foundation is built upon sedimentary rock layers that have been shaped by glacial activity over thousands of years. This has resulted in broad, sweeping valleys separated by low ridges and hills that rarely exceed 200-300 feet in relative height difference. Small streams and creeks flow through these valleys, eventually draining northward toward Lake Erie or southward into the Allegheny River system.

Drainage Patterns and Water Features

The local watershed is defined by several small tributaries that meander through the landscape, creating natural drainage corridors. These waterways have carved gentle valleys that break up the otherwise rolling terrain. Seasonal wetlands and small ponds dot the area, particularly in lower-lying sections where water naturally collects during spring snowmelt and periods of heavy precipitation. The soil composition varies across the region, with well-drained loamy soils on the higher elevations transitioning to heavier clay soils in the valley bottoms. This variation in soil types has historically influenced land use patterns, with the better-drained upland areas typically used for crop production and the lower areas often remaining in pasture or woodland.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations in this region would be the broad, gently sloping upland areas that offer several key advantages. These elevated plateaus and ridge tops provide relatively flat to slightly sloping terrain that minimizes grading requirements and reduces installation costs. The higher elevations also tend to have fewer trees and are often already cleared for agricultural use, reducing the need for extensive site preparation. South-facing slopes throughout the region present particularly attractive opportunities for solar development, as they naturally optimize panel orientation for maximum energy capture throughout the day. These areas typically have good drainage characteristics, which helps prevent water accumulation around solar installations and reduces long-term maintenance concerns. The agricultural fields scattered across the rolling landscape offer another category of prime solar real estate. Many of these areas feature large, contiguous parcels of relatively level ground with established access roads and proximity to existing electrical infrastructure. The open nature of these agricultural areas also means minimal shading concerns from surrounding vegetation or structures. Areas to avoid for large-scale solar development would include the steeper valley sides where erosion could become problematic, heavily forested sections that would require extensive clearing, and low-lying areas prone to seasonal flooding or poor drainage. The numerous small wetlands and stream corridors throughout the region should also be avoided to minimize environmental impact and regulatory complications.
