Johnstown, New York, located in the Northern Temperate Zone at coordinates 43.0083, -74.3688, presents a mixed picture for year-round solar PV energy generation. The location experiences significant seasonal variations in solar output, which impacts its overall suitability for solar power production.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.66 kWh per day output for each kW of installed solar capacity. Spring follows closely behind, generating 4.98 kWh per day. These seasons offer ideal conditions for solar energy production, with longer daylight hours and more direct sunlight. Autumn sees a notable decrease in solar output, dropping to 2.82 kWh per day. Winter presents the most challenging conditions, with production plummeting to just 1.67 kWh per day. This significant seasonal variation highlights the importance of efficient system design and energy storage solutions to maintain consistent power supply throughout the year.

Optimal Panel Installation

For fixed panel installations in Johnstown, the ideal tilt angle to maximize year-round solar production is 37 degrees facing South. This angle optimizes the panels' exposure to sunlight across all seasons, balancing the high summer sun with the lower winter sun angle.

Environmental and Weather Considerations

Several factors could potentially impede solar production in Johnstown: 1. Snowfall: The region experiences significant snowfall in winter, which can cover panels and reduce efficiency. Regular panel cleaning and the use of snow-shedding systems can mitigate this issue. 2. Cloud cover: Johnstown has a considerable number of cloudy days, particularly in winter and early spring. Using high-efficiency panels and microinverters can help maximize energy production even in low-light conditions. 3. Temperature fluctuations: Extreme cold in winter can affect panel efficiency, while high summer temperatures can also reduce performance. Choosing temperature-resistant panels and ensuring proper ventilation can help maintain optimal performance. To address these challenges, installers should consider using durable, weather-resistant panels, implementing effective snow removal strategies, and designing systems with ample capacity to compensate for seasonal variations. Additionally, incorporating energy storage solutions can help balance the significant difference between summer and winter production rates. In conclusion, while Johnstown's location presents some challenges for year-round solar energy production, particularly in winter, the strong performance in spring and summer makes it a viable option for solar PV installations when properly designed and maintained.

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

Seasonal solar PV output for Latitude: 43.0083, Longitude: -74.3688 (Johnstown, 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 37° South in Johnstown, New York, United States

To maximize your solar PV system's energy output in Johnstown, New York, United States (Lat/Long 43.0083, -74.3688) 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 Johnstown, 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 Johnstown, New York, 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	58° 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 Johnstown, New York, 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 Johnstown, New York, 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 Johnstown, New York, United States

The topography around Johnstown, New York, is characterized by a mix of gently rolling hills, small valleys, and relatively flat areas. This region, located in the southern Adirondack foothills, features a landscape that has been shaped by glacial activity during the last ice age. The terrain is generally mild, with elevations ranging from about 600 to 1,000 feet above sea level. The area surrounding Johnstown is part of the Mohawk Valley, which runs east to west through this part of New York State. The valley floor is relatively flat, with some low-lying areas and occasional wetlands. As you move away from the valley, the land gradually rises into a series of hills and ridges, creating a patchwork of open fields, forested areas, and small streams.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would be relatively flat, open areas with good sun exposure and minimal shading from trees or hills. Based on the topography of the region, the following areas near Johnstown could be potential candidates: The flatter portions of the Mohawk Valley, particularly to the south and southeast of Johnstown, offer promising locations for solar farms. These areas often feature expansive agricultural fields that could potentially be repurposed or shared with solar installations. Some of the gentler hillsides and plateaus to the north and west of Johnstown might also be suitable, especially if they have a southern exposure. These elevated areas could potentially receive more direct sunlight throughout the day, increasing their efficiency for solar power generation. It's important to note that while the topography is generally favorable for solar PV in many areas around Johnstown, other factors such as land ownership, zoning regulations, proximity to power infrastructure, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar projects. Additionally, a detailed site-specific analysis would be necessary to accurately assess the solar potential of any given location in the area.

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.
