Keswick, Ontario, Canada, situated at 44.2392° N latitude and -79.477° W longitude, offers a varied landscape for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences distinct seasonal fluctuations in solar energy production.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy generation in Keswick, Ontario, with an impressive daily output of 5.97 kWh per kW of installed solar capacity. Spring follows closely behind, producing 5.29 kWh/day. These seasons present ideal conditions for maximizing solar energy production.

Autumn sees a significant decrease in solar output, generating 3.02 kWh/day. Winter experiences the lowest production, with only 1.75 kWh/day, due to shorter daylight hours and less direct sunlight.

Optimal Panel Positioning

To maximize year-round solar energy production in Keswick, Ontario, fixed solar panels should be installed at a tilt angle of 38 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and seasonal sun positions.

Environmental Considerations

While Keswick's location is generally favorable for solar energy production, there are some environmental factors to consider:

• Snow accumulation in winter can temporarily reduce panel efficiency
• Cloudy days, particularly common in autumn and winter, may decrease daily output

To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off and use high-efficiency panels that perform well in low-light conditions. Regular maintenance, including snow removal, can also help maintain optimal performance year-round.

Despite the seasonal variations, Keswick's location offers good potential for solar energy generation, especially during the spring and summer months. With proper installation and maintenance, a solar PV system can provide a significant contribution to a household's or business's energy needs throughout the year.

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 569 locations across Canada. 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 Keswick

Seasonal solar PV output for Latitude: 44.2392, Longitude: -79.477 (Keswick, 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 Keswick, Canada

To maximize your solar PV system's energy output in Keswick, Canada (Lat/Long 44.2392, -79.477) 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 Keswick, 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 Keswick, 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 Keswick, 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 Keswick, 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 Keswick, Canada

The area surrounding Keswick, Canada, located at 44.2392° North latitude and 79.477° West longitude, is characterized by gently rolling terrain typical of the southern Ontario region. This topography is a result of glacial activity during the last ice age, which shaped the landscape into a mix of low hills, shallow valleys, and flat plains. Keswick sits on the southeastern shore of Lake Simcoe, a large freshwater lake that significantly influences the local topography. The shoreline area is relatively flat, with some gentle slopes leading down to the water's edge. As you move away from the lake, the land gradually rises, forming subtle undulations across the countryside.

Surrounding Landscape

To the east and south of Keswick, the terrain becomes slightly more varied, with small hills and valleys interspersed with agricultural fields and patches of forest. These areas are part of the Oak Ridges Moraine, a prominent geological feature that runs east-west across south-central Ontario. While not mountainous, this region does offer some elevation changes that create a diverse landscape. To the west and northwest, the land is generally flatter, dominated by farmland and rural residential areas. This relatively level terrain extends towards the neighboring towns of Sutton and Pefferlaw.

Potential for Solar PV Installation

When considering areas suitable for large-scale solar PV installations near Keswick, several factors come into play. The gently rolling terrain in much of the surrounding area can be advantageous for solar farms, as it provides natural drainage and reduces the risk of shadowing between solar panels. The agricultural lands to the west and northwest of Keswick present promising opportunities for solar development. These areas offer expansive, open spaces with minimal obstructions, allowing for optimal sun exposure throughout the day. The relatively flat terrain in this direction also simplifies the installation process and reduces construction costs. Areas to the south and southeast, while slightly more varied in topography, could also be suitable for solar PV projects. The gentle slopes in these regions can be utilized to maximize solar panel efficiency by orienting them towards the sun. However, care must be taken to avoid areas with significant tree cover or steep inclines that could impact solar exposure. It's important to note that while the topography around Keswick is generally favorable for solar PV installations, other factors such as local zoning regulations, proximity to electrical infrastructure, and environmental considerations would also need to be taken into account when selecting specific sites for large-scale solar projects.

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]
