Solar panels in Langley, British Columbia

Langley’s mix of urban and agricultural properties creates diverse solar opportunities. Production of 1,010 kWh/kW. Larger rural lots often have excellent unshaded roof exposure. BC Hydro rebates (up to $5,000 for solar plus battery rebate (up to $1,500 without Peak Saver, or up to $5,000 with Peak Saver)) and PST exemption apply.

Note: The federal Canada Greener Homes Grant and Loan programs are now closed.

Until 1 July 2026 a Langley homeowner faced a genuine decision: take BC Hydro’s solar rebate, or stay on 1:1 net metering and bank every exported kilowatt-hour at full retail value. That decision no longer exists. Following a BC Utilities Commission ruling, BC Hydro closed the net metering rate (Rate Schedule 1289) to new customers on 1 July 2026.

New systems go on Rate Schedule 2289 instead. BC Hydro buys your excess generation at a fixed 10 cents per kWh, and — a real improvement on the old arrangement — pays you every billing cycle rather than banking credits until a yearly reconciliation. Because retail electricity in Langley costs more than 10 cents, a kilowatt-hour you use yourself is now worth more than one you export. That makes the shape of your daily consumption matter in a way it did not before: running the dishwasher at noon rather than at midnight is now worth something.

Take the rebate. Declining it no longer preserves 1:1 net metering, because that rate is closed to new customers regardless. BC Hydro’s own position is that the solar rebate is expected to fully offset the impact of the rate change for an average residential customer. One distinction worth knowing: if you accept only the battery rebate and no solar rebate, your service rate is unaffected. BC Hydro also does not permit a pro-rated or combined arrangement across the two rates — it is one or the other.

Langley is modelled at 1,010 kWh per kW a year. Among the Lower Mainland cities on this site only Chilliwack, at 1,050, and Abbotsford, at 1,030, are higher — and Langley is exactly level with Vancouver, ahead of Surrey at 1,000, Richmond at 990, Burnaby and Coquitlam at 980, and North Vancouver at 960.

The pattern is consistent and worth understanding, because it is the same effect all the way up the valley. The marine cloud that sits over the coast thins as you move east; the further inland you go, the more of the available daylight arrives as direct sun. Langley’s warm, dry summers are the local expression of that, and Chilliwack’s slightly better figure is the same trend continued another thirty kilometres.

What that is worth in practice is modest — about five per cent against North Vancouver, and nothing at all against Vancouver. It is not a reason to choose Langley, and it is certainly not a reason to think a Langley roof needs less scrutiny than a coastal one.

Where it does help is at the margin. A roof plane that is borderline at 960 becomes more defensible at 1,010, so households whose only usable aspect is imperfect have a little more room here than on the North Shore.

Payback of 10 to 13 years reflects that: better than the coastal municipalities, behind the interior. Kamloops, at 1,250, is in a different category altogether, and if you are comparing figures with relatives in the interior, that gap is real rather than a modelling artefact.

Langley includes a good deal of larger-lot housing — Fort Langley, Brookswood, Aldergrove and the rural edges have properties with roof area, outbuildings and room that a Burnaby townhouse does not have. Until this year the advice for such a property was simple: use it.

That advice has changed, and the reason is tariff rather than technology. BC Hydro closed its 1:1 net metering rate, Rate Schedule 1289, to new customers on 1 July 2026 following a BC Utilities Commission decision. New self-generation customers take Rate Schedule 2289, under which exports are bought at a fixed 10 cents per kilowatt-hour, paid each billing cycle. You buy electricity back at 11.87 cents on Step 1 and 14.08 on Step 2.

Under the old rate, a larger array on a larger roof simply banked more credit at full value, so spare capacity cost you only the price of the panels. Under the new one, generation beyond your own consumption is sold at a discount to what you pay. The roof still has the room; the tariff no longer rewards filling it.

This is not an argument for a small system. Larger properties often have genuinely larger consumption — well pumps, shops, outbuildings, more heating — and where the consumption is real the system should match it. It is an argument against sizing from square metres.

The practical sequence is unchanged from the rest of the province, but it bites harder here: total twelve months of actual kilowatt-hours, size to that, and treat any capacity beyond it as an export-priced investment rather than a retail-priced one. Where the roof genuinely outruns the household, storage or shifting load into daylight is the better use of the surplus.
