Solar Energy Potential in Gloucester, Ontario, Canada
Gloucester, Ontario, Canada, located at 45.3516° N, 75.6339° W in the Northern Temperate Zone, shows significant seasonal variation in its solar energy generation potential. This location experiences strong solar performance during warmer months but faces substantial challenges during the colder seasons. The solar energy output varies dramatically throughout the year. During summer, solar panels can produce an impressive 5.92 kWh per day for each kilowatt of installed capacity. Spring follows closely with 5.40 kWh/day per kW. However, production drops considerably to 2.81 kWh/day in autumn and reaches a low of just 1.76 kWh/day during winter months.Optimal Panel Installation
For fixed solar panel installations in Gloucester, Ontario, the ideal tilt angle to maximize year-round energy production is 39 degrees facing South. This specific angle has been calculated to optimize solar collection throughout the changing seasons, accounting for the Earth's elliptical orbit and the location's position in the Northern Hemisphere.Environmental and Weather Challenges
Several significant factors can impede solar production at this location:- Snow accumulation during winter months can completely cover panels, blocking sunlight and drastically reducing output during a season that already has minimal production
- Frequent cloudy days, particularly in late autumn and winter, further reduce the already limited solar radiation
- Freezing rain events can create ice layers on panels that are difficult to remove
- Temperature extremes, with very cold winters potentially affecting equipment performance
Preventative Measures
To maximize energy production despite these challenges, several preventative measures can be implemented:- Install panels at a steeper angle than the optimal 39 degrees in areas prone to heavy snowfall to encourage snow sliding off
- Implement regular snow removal procedures during winter months
- Consider dual-axis tracking systems to maximize collection during limited winter daylight
- Use high-efficiency panels designed for cold-weather performance
- Apply anti-soiling and ice-resistant coatings to panel surfaces
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 Gloucester
Seasonal solar PV output for Latitude: 45.3516, Longitude: -75.6339 (Gloucester, 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 39° South in Gloucester, Canada
To maximize your solar PV system's energy output in Gloucester, Canada (Lat/Long 45.3516, -75.6339) throughout the year, you should tilt your panels at an angle of 39° 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 Gloucester, 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 Gloucester, Canada. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 29° South in Summer | 49° South in Autumn | 59° South in Winter | 38° 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 Gloucester, 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 Gloucester, Canada.
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 Gloucester, Canada
The area around Gloucester, Canada, which is situated at approximately 45.3516°N, 75.6339°W, presents a varied topography typical of the Ottawa Valley region in Eastern Ontario. This suburban area, now part of Ottawa, lies along the eastern banks of the Ottawa River and features gently rolling terrain with modest elevation changes. The landscape gradually rises from the river valley, with some areas displaying small hills and ridges interspersed with flatter plateaus.
Topographical Features
The topography around Gloucester is characterized by post-glacial features, including some drumlins and eskers formed during the last ice age. The terrain is generally flat to gently undulating, with elevations typically ranging between 70 to 100 meters above sea level. The Ottawa River forms a significant natural boundary to the north and west, with its associated floodplains and terraces adding complexity to the local landscape. Several creeks and smaller waterways, including Green's Creek and Bilberry Creek, have carved shallow valleys through the area, creating natural drainage systems that flow toward the Ottawa River. These waterways have shaped local relief features, producing some areas with steeper slopes near their banks. The soil composition varies across the region, with significant areas of clay plains resulting from the ancient Champlain Sea that once covered the region following glacial retreat. Some areas also feature sandy deposits and occasional rocky outcrops, particularly in the slightly higher elevation areas.Solar PV Suitability
For large-scale solar photovoltaic installations, several areas near Gloucester present favorable conditions based on topographical considerations. The most suitable locations would be: The open agricultural lands to the east and southeast of Gloucester offer relatively flat terrain with minimal shading obstacles. These areas, extending toward Carlsbad Springs and Russell, provide expansive spaces with consistent elevation that would minimize installation complexity and maximize exposure to sunlight throughout the day. Former industrial lands and brownfield sites in the eastern portions of Gloucester present opportunities for solar development without disrupting natural habitats or agricultural production. These areas often feature cleared, level terrain already connected to existing infrastructure. The slightly elevated plateaus south of Gloucester, extending toward Leitrim and Findlay Creek, offer good solar potential with their open aspect and minimal surrounding obstructions. These higher grounds typically experience less fog and ground-level atmospheric interference. Areas to avoid would include the river valleys and creek ravines, which experience more shading and have steeper slopes that complicate installation. Additionally, the wetland areas scattered throughout the region would present both environmental and practical challenges for solar development. The clay-heavy soils in some parts of the region may require special consideration for the anchoring systems of solar arrays, as they can experience significant seasonal movement with freeze-thaw cycles. The sandy soil areas might offer more stable foundations for larger installations. Overall, the geography around Gloucester presents numerous viable options for solar PV development, with the most promising sites being the open, elevated areas with southern exposure, good drainage, and minimal natural obstructions.Canada solar PV Stats as a country
