Solar PV Analysis of West Kelowna, Canada
West Kelowna, British Columbia, Canada, located in the Northern Temperate Zone, offers varying levels of solar energy potential throughout the year. During summer and spring, there is a high potential for generating solar energy with an average of 6.99kWh/day and 5.48kWh/day per kW of installed solar respectively. This means that these seasons are ideal for generating solar power due to longer daylight hours and higher sun intensity.
However, in autumn and winter, the amount of sunlight decreases significantly leading to lower electricity output from your solar panels - about 2.52kWh/day in autumn and even lower at 1.34kWh/day during winter.
To maximize your total year-round production from your solar panels at this location, you should tilt them at an angle of 42 degrees facing south. This angle is ideal because it allows the panels to capture as much sunlight as possible throughout different times of the day and across different seasons.
As for environmental or local factors that could affect solar production in West Kelowna; it's important to consider things like weather patterns (including cloud cover), topography (like mountains or large buildings that might block sunlight), as well as local wildlife or vegetation (which could potentially damage or obstruct your panels).
For instance, West Kelowna experiences a significant amount of snowfall during winter months which can cover up your panels reducing their efficiency significantly if not cleared regularly.
To prevent these issues:
1) Regular maintenance including cleaning off any snow or debris from your panel surfaces is key.
2) If possible install your system on a part of your property where obstructions are minimal.
3) Consider installing protective measures like fences or screens if wildlife or falling branches pose a risk.
4) Monitor weather patterns closely so you can adjust system operation accordingly if needed i.e., during periods with heavy cloud cover when productivity might be reduced.
So while West Kelowna does offer some good potential for solar energy generation, particularly in the warmer months, it's important to carefully consider these factors and take appropriate measures to ensure your system is as productive as possible year-round.
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 West Kelowna
Seasonal solar PV output for Latitude: 49.866, Longitude: -119.7387 (West Kelowna, 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 42° South in West Kelowna, Canada
To maximize your solar PV system's energy output in West Kelowna, Canada (Lat/Long 49.866, -119.7387) throughout the year, you should tilt your panels at an angle of 42° 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 West Kelowna, 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 West Kelowna, Canada. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 33° South in Summer | 53° South in Autumn | 64° South in Winter | 42° 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 West Kelowna, 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 West Kelowna, 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 West Kelowna, Canada
West Kelowna, located in the Okanagan Valley of British Columbia, Canada, is surrounded by mountains and valleys with a significant amount of forested areas. It is situated on the western shores of Okanagan Lake.
The area experiences a semi-arid climate with hot, sunny summers which could be beneficial for solar power generation. However, the mountainous and forested terrain might pose some challenges for large scale solar installations due to potential shading issues and land availability.
Ideal locations for large-scale solar PV installations would typically be flat open spaces with minimal shading and good sun exposure. Given this criteria, areas such as agricultural lands or cleared industrial lands in the valley could potentially be suitable.
It's also worth noting that West Kelowna's location near Okanagan Lake can create a microclimate effect where certain parts of the region may receive more sunshine than others - these spots could potentially be viable for solar power generation.
However, any decision about installing large-scale solar PV should also take into account other factors like local regulations, environmental impact assessments and grid connectivity among others. A detailed feasibility study would need to be conducted to determine the most suitable sites.
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]
Are there incentives for businesses to install solar in Canada?
