Solar panels in Vancouver, BC

Roofs in Vancouver get about 1,162 hours of usable sunlight a year — less than 85% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.

Check your specific roof in Vancouver → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.

What a typical Vancouver solar system costs

A 28-panel system (11.2 kW) is about right for an average Vancouver home using 10,800 kWh a year. It would produce roughly 11,062 kWh annually and offset 100% of that usage.

How we worked this out for Vancouver

Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Vancouver rooftops.

Step 6 matters more than it looks. Only 34% of what a system this size produces in Vancouver is used the moment it is generated; the other 7,282 kWh is exported and credited one-for-one under net metering. Because exports here are credited at or near retail, that split changes the payback very little — 23.3 years against the 23.7 we show. In places where exports pay a fraction of retail the same split moves payback by years, which is why we model it explicitly rather than assuming.

Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), CA$2.85/W installed, 10,800 kWh typical annual household use, 12.4¢/kWh electricity. Change any of those and every figure above moves — which is exactly why a single national "solar costs X" number is misleading.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why Vancouver gets 1,162 sun hours

That figure comes from Google's analysis of real rooftops across Vancouver — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Vancouver reaches about 1,324 hours, roughly 14% better than typical.

When Vancouver actually produces

Annual totals hide the thing that catches people out: 41% of Vancouver's yearly sunlight arrives in May–July, and just 10% across November–January.

That is a severe seasonal swing — Vancouver produces roughly 5.1× as much in Jun as in Dec. A system sized to cover your annual usage will overproduce badly in summer and fall well short in winter, so how your utility credits exported power matters more here than in most places.

The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Vancouver's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How Vancouver compares to the other 788 cities

What actually stands out about Vancouver:

• Shading is a real problem here. Vancouver loses 12% of its potential sunlight to trees, chimneys and neighbouring buildings — the 29th-worst of the 788 cities measured. Panel placement matters more here than in most places, and a roof survey is worth more than a phone quote.
• The case here is financial, not environmental. Vancouver's grid is already clean at 151 kg CO₂ per MWh, so the carbon saving from solar is modest. Judge this one on payback.
• Older imagery. Google's aerial capture of Vancouver dates from 2021. Tree growth and new construction since then are not reflected.

Cities with almost the same sunlight

These are the closest matches to Vancouver's 1,162 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
