Is Solar Worth It in BC
Is solar worth it in BC? The honest payback math
Here's the part the installer won't lead with: rooftop solar in BC is genuinely marginal. BC Hydro power is among the cheapest in North America, so every kWh your panels make offsets less money than it would in Ontario, Alberta, or the US. For some homes the math works; for many the honest answer is "not yet."
The short answer
- Solar is marginal in BC — cheap hydro means each kWh offsets only ~13.1¢.
- Payback is typically 10–15 years, and 16–20 for export-heavy systems under the new rules.
- It depends on your self-consumption, roof, utility, and rebates — not a single national average.
- For some homes it clearly pays; for many it doesn't yet — and that honesty is the point.
- The $19 kit gives you your number, not a sales pitch.
Why BC is the hard case for solar
Solar economics are simple at heart: a system costs money up front, and every kWh it makes saves you whatever a kWh would have cost from the grid. The catch in BC is that grid power is dirt cheap — retail BC Hydro is around 13.1¢/kWh, far below Ontario, Alberta, or most US states. So the same panels that pay off in 7 years in California take far longer here. This isn't pessimism; it's arithmetic. Installers are paid to say yes, which is exactly why an honest second opinion is worth having.
What a BC roof actually produces
Production in BC is decent — not Arizona, not terrible:
- Coast: roughly 1,000 kWh per kW per year. A 6 kW array makes about 6,000 kWh/yr.
- Southern Interior (Okanagan, Kootenays): the sunniest, around 1,130 kWh/kW (Kelowna 1,132 per NRCan).
- Northern BC: better than you'd expect — around 1,050 kWh/kW (Prince George 1,056), as clear, cold winters offset the shorter season.
East- or west-facing roofs and any shading (trees, chimneys, neighbouring buildings) cut that further. A south-facing, unshaded roof is the difference between a payback that's merely long and one that's genuinely not worth it.
So what's the payback?
A typical residential system costs roughly $11,000–$14,000 after rebates. On a 6 kW system, the annual bill offset is only a few hundred dollars — about $674/yr under the new export rules. Do the division and you land at a payback of roughly 16–20 years in many cases. With strong daytime self-consumption (you use what you make, rather than exporting it cheaply), it can come down to 10–15 years. That spread — driven almost entirely by how much of your own power you use versus export — is the whole ballgame in BC.
Rebates help — but don't close the gap on their own
BC's incentives are real and meaningful: BC Hydro offers up to $5,000 for solar panels, up to $5,000 for a battery, and a $2,000 income supplement on top. Those are what bring a system down to that $11–14k after-rebate figure. They improve the payback materially — but they don't turn a 20-year payback into a 5-year one.

The 2026 net-metering change makes export worth less
This is the big one most calculators still ignore. BC Hydro's old 1:1 net metering (rate RS 1289) closes to new customers on July 1, 2026. New solar customers move to the Self-Generation rate (RS 2289), which credits exported surplus at roughly 10¢/kWh — below the ~13.1¢ retail rate. If your system exports most of what it makes, that gap directly lengthens your payback. FortisBC keeps its own 1:1 program, which is one reason the answer differs by utility.

When solar is worth it in BC
- High daytime self-consumption — you're home during the day, charge an EV, or run a heat pump, so you use what you make instead of exporting it cheaply.
- A larger electricity bill — more offset to capture means a shorter payback.
- FortisBC territory — keeping 1:1 export makes the math noticeably better than under RS 2289.
- A strong south-facing, unshaded roof in the Southern Interior — best production per kW in the province.
- You value carbon or resilience over pure payback — a legitimate reason that just isn't a financial one.
When it isn't (yet)
- A small bill — little to offset, so the system can't pay for itself in a reasonable time.
- Significant shading — trees or surrounding buildings that knock down production.
- East/west-only roof orientation — meaningfully less yield than south-facing.
- You'd export most of it — under RS 2289, that power is worth only ~10¢/kWh, which stretches payback to the back half of the panels' life.
Bottom line
There's no single yes-or-no on BC solar. It's marginal because hydro is cheap, payback usually runs 10–15 years (longer for export-heavy systems), and the right answer depends on your self-consumption, roof, utility, and rebates. For the right home it pays off; for many it doesn't yet. The point isn't to talk you out of it — it's to give you the real number before you sign a contract. That's what the paid kit is built to do, and you can start with how the payback math works.
