Tonawanda, New York, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation via photovoltaic (PV) panels. The location's potential for solar power production varies significantly throughout the year, with notable fluctuations across seasons.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.04 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.19 kWh/day. However, the output drops considerably in autumn to 3.06 kWh/day, and winter sees a dramatic decrease to just 1.71 kWh/day.

These figures indicate that Tonawanda experiences a substantial difference in solar potential between the warmer and colder months. The location is most ideal for solar energy production from late spring through early fall, with peak performance during the summer months when daylight hours are longest and sun angle is highest.

Optimal Panel Installation

To maximize year-round solar energy production in Tonawanda, fixed solar panels should be installed at a tilt angle of 37 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the lower winter sun with the higher summer sun.

Environmental Considerations

Several environmental factors in Tonawanda could potentially impact solar energy production:

1. Snow accumulation in winter, which can cover panels and reduce output
2. Cloudy weather, particularly common in the Great Lakes region

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and using high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal, is crucial for optimal performance.

While Tonawanda's location isn't ideal year-round for solar PV, with proper installation and maintenance, it can still provide significant energy production, especially during the warmer months. The substantial summer and spring output can help offset the reduced winter production, making solar a viable option for this area.

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 Tonawanda

Seasonal solar PV output for Latitude: 43.0037, Longitude: -78.8496 (Tonawanda, 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 37° South in Tonawanda, United States

To maximize your solar PV system's energy output in Tonawanda, United States (Lat/Long 43.0037, -78.8496) throughout the year, you should tilt your panels at an angle of 37° 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 Tonawanda, 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 Tonawanda, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
27° South in Summer	47° South in Autumn	57° South in Winter	36° 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 Tonawanda, 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 Tonawanda, 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 Tonawanda, United States

The area around Tonawanda, New York, is characterized by relatively flat terrain typical of the Great Lakes region. Situated along the Niagara River, Tonawanda and its surrounding areas are part of the Erie-Ontario Lowlands, a region known for its gently rolling plains and low-lying topography. The landscape is predominantly level, with only slight variations in elevation across the area. To the north and east of Tonawanda, the land gradually slopes towards Lake Ontario, while to the south and west, it remains mostly flat as it extends towards Buffalo and the eastern shores of Lake Erie. The Niagara River, which forms part of Tonawanda's western border, has carved a shallow valley through the region, but dramatic changes in elevation are rare.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain surrounding Tonawanda offers some advantages for solar development, as it reduces the need for extensive land preparation and allows for easier installation of solar panels. Rural areas to the east and northeast of Tonawanda, extending towards Lockport and beyond, present potential opportunities for large-scale solar PV projects. These areas often feature expansive agricultural lands and open fields that could be repurposed or dual-used for solar energy production. The relatively unobstructed horizons in these rural settings can maximize sun exposure throughout the day. Additionally, areas south of Tonawanda, towards Cheektowaga and Lancaster, might also be suitable for solar development. These locations offer a mix of industrial zones and open spaces that could accommodate large solar installations while being close to existing power infrastructure and urban centers that demand electricity. It's important to note that while the topography is favorable, other factors such as local zoning regulations, proximity to power grids, and environmental considerations would need to be carefully evaluated before determining the most suitable locations for large-scale solar PV projects in the region.

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.
