Weston, Ontario, Canada, located at latitude 43.7032 and longitude -79.5293, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

The solar energy production in Weston varies considerably across the four meteorological seasons. Summer stands out as the most productive period, with an average daily output of 6.16 kWh per kW of installed solar capacity. Spring follows closely, generating 5.25 kWh/day. However, there's a notable decline in autumn, with 3.10 kWh/day, and a significant drop in winter, producing only 1.81 kWh/day.

These figures indicate that Weston's location is most ideal for solar energy generation during the warmer months, particularly from late spring through early fall. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Weston, Ontario, fixed solar panels should be installed at a tilt angle of 37 degrees facing south. This optimal angle ensures the best possible exposure to sunlight throughout the year, balancing the seasonal variations in sun position and intensity.

Environmental and Weather Considerations

While Weston's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:

1. Snow accumulation in winter: Heavy snowfall can temporarily reduce solar panel output.
2. Cloud cover: Frequent cloudy days, especially in autumn and winter, can diminish solar energy generation.

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

In conclusion, while Weston's location presents challenges for year-round solar energy production, particularly in winter, it remains a viable option for renewable energy. With proper installation techniques and maintenance, solar PV systems can effectively contribute to the area's energy needs, especially during the more productive spring and summer months.

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

Seasonal solar PV output for Latitude: 43.7032, Longitude: -79.5293 (Weston, 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 37° South in Weston, Canada

To maximize your solar PV system's energy output in Weston, Canada (Lat/Long 43.7032, -79.5293) 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 Weston, 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 Weston, Canada. 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 Weston, 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 Weston, 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 Weston, Canada

The topography around Weston, Canada, located at latitude 43.7032 and longitude -79.5293, is characterized by a gently rolling landscape typical of Southern Ontario. This area, situated within the Greater Toronto Area, features a mix of urban development and natural features that have been shaped by glacial activity thousands of years ago. The terrain in and around Weston is generally flat to slightly undulating, with subtle variations in elevation. The most prominent topographical feature in the vicinity is the Humber River valley, which runs north-south just to the east of Weston. This river valley creates a natural depression in the landscape, with steeper slopes leading down to the water's edge. The surrounding areas are mostly composed of low-lying plains with occasional small hills and ridges.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat, open spaces with minimal shading from trees or buildings, and good access to existing power infrastructure. One potential area for solar PV development could be the former Kodak Heights lands, located just north of Weston. This large, mostly flat industrial site has been undergoing redevelopment and could potentially accommodate solar installations as part of its transformation. Another suitable location might be found in the agricultural areas to the northwest of Weston, towards Vaughan. These open fields provide ample space and minimal obstruction for solar panels. However, the conversion of farmland for solar use would need to be carefully considered in terms of land-use planning and food security. The hydro corridors that run through the region could also offer potential for solar PV installations. These linear strips of land are already dedicated to power infrastructure and often feature open, grassy areas that could be utilized for solar panels without significantly altering existing land use. It's important to note that while the topography around Weston is generally favorable for solar PV, the dense urban development in much of the area may limit the availability of large, contiguous spaces required for utility-scale solar farms. As such, smaller-scale installations on rooftops and in parking lots might be more feasible in the immediate vicinity of Weston itself.

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]
