Gananoque, Ontario, Canada, situated at coordinates 44.3322, -76.1676, presents a mixed landscape for solar energy production throughout the year. Located in the Northern Temperate Zone, this region experiences distinct seasonal variations that significantly impact solar PV efficiency.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.94 kWh per day output for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.33 kWh/day. These warmer months offer ideal conditions for solar energy harvesting, with longer daylight hours and more direct sunlight.

However, the colder seasons see a notable decline in solar efficiency. Autumn yields 2.96 kWh/day, while winter experiences a substantial drop to just 1.74 kWh/day per kW installed. This significant reduction is primarily due to shorter days, lower sun angles, and increased cloud cover typical of Canadian winters.

Optimal Panel Installation

To maximize year-round solar production in Gananoque, Ontario, fixed solar panels should be tilted at a 38-degree angle facing south. This orientation ensures optimal exposure to sunlight throughout the year, balancing the varying sun angles across seasons.

Environmental Considerations

Several environmental factors can affect solar production in Gananoque:

• Snow accumulation in winter can significantly reduce panel efficiency
• Tree cover and building shadows may limit sunlight exposure in urban areas

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off, and conduct thorough site assessments to minimize shading. Regular panel cleaning and maintenance, especially after snowfall, can help maintain optimal performance.

In conclusion, while Gananoque's location is not ideal for year-round solar production due to significant seasonal variations, proper installation techniques and maintenance can still make solar PV a viable energy option, particularly during the spring and summer months.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Gananoque

Seasonal solar PV output for Latitude: 44.3322, Longitude: -76.1676 (Gananoque, Canada), 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 38° South in Gananoque, Canada

To maximize your solar PV system's energy output in Gananoque, Canada (Lat/Long 44.3322, -76.1676) throughout the year, you should tilt your panels at an angle of 38° 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 Gananoque, Canada

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 Gananoque, Canada. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	48° South in Autumn	58° South in Winter	37° 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 Gananoque, Canada

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 Gananoque, Canada.

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 Gananoque, Canada

The topography around Gananoque, Canada, is characterized by a diverse and picturesque landscape that reflects the region's glacial history and its location at the eastern end of Lake Ontario. Situated in the Thousand Islands region, Gananoque is surrounded by a mix of gently rolling hills, rocky outcrops, and numerous small islands dotting the St. Lawrence River. The area features a combination of forested lands, open fields, and wetlands. The terrain is generally undulating, with elevations ranging from about 80 meters above sea level near the shoreline to around 150 meters in the higher areas inland. The landscape is punctuated by numerous small lakes, ponds, and streams, creating a complex network of waterways that drain into the St. Lawrence River. To the north and west of Gananoque, the land gradually rises, forming part of the Canadian Shield. This ancient geological formation is characterized by exposed bedrock, thin soil cover, and a more rugged terrain. The Shield's presence contributes to the area's unique topography, with scattered granite outcrops and small cliffs visible throughout the region.

Potential Areas for Large-Scale Solar PV

When considering areas near Gananoque that might be suitable for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have relatively flat or gently sloping terrain, good sun exposure, and minimal shading from trees or other obstacles. The agricultural lands to the south and southwest of Gananoque offer promising potential for solar PV development. These areas typically feature open fields with fewer trees, providing excellent sun exposure throughout the day. The gently rolling terrain in this region would allow for efficient panel placement without requiring extensive land modification. Another potentially suitable area lies to the northwest of Gananoque, where there are pockets of cleared land amidst the more forested regions of the Canadian Shield. While care would need to be taken to avoid ecologically sensitive areas, these clearings could provide good sites for solar installations, particularly on south-facing slopes that receive abundant sunlight. It's important to note that any large-scale solar PV project would require careful environmental assessment and community consultation. The region's natural beauty and ecological importance, particularly around the Thousand Islands, means that visual impact and habitat preservation would be crucial considerations in selecting suitable sites for solar development.

Canada solar PV Stats as a country

Canada ranks 23rd in the world for cumulative solar PV capacity, with 3,630 total MW's of solar PV installed. This means that 0.70% of Canada's total energy as a country comes from solar PV (that's 38th in the world). Each year Canada is generating 96 Watts from solar PV per capita (Canada ranks 40th in the world for solar PV Watts generated per capita). [source]
