What a Kelowna roof produces in a year
Natural Resources Canada models Kelowna at about 1,132 kWh a year for every kW of installed panel capacity on a well oriented array. A 7 kW system therefore lands somewhere near 7,900 kWh a year, and a 10 kW system near 11,300. Those are annual totals and the year is uneven: production concentrates in the long days on either side of midsummer and thins out through the darkest weeks, so the useful comparison is against a full year of your own consumption rather than a single month.
Beyond the yield figure, the roof decides the outcome. South facing planes gather the most across a year, east and west planes trade some annual total for output spread through the morning and afternoon, and a north face rarely earns its racking. Snow is a design input anywhere panels see a real winter: a covered array produces nothing until it clears, and the mounting and the structure beneath it have to carry the accumulated load. Shade should be measured rather than judged by eye, because a single shaded module can drag down an entire string unless the design uses microinverters or per panel optimisers.
You are a FortisBC customer, not a BC Hydro one
This is the fact that changes everything else on the page. Kelowna is served by FortisBC, which runs under its own tariff and its own rules. BC Hydro's move off net metering, which reshaped the economics of solar elsewhere in British Columbia, does not apply to you. Advice written for a Vancouver or Victoria homeowner about export credits and closed rate schedules is simply about a different utility.
FortisBC net metering, Schedule 95, remains open to new customers for systems up to 50 kW. That ceiling is far above anything a house would install, so for residential purposes it is not a constraint at all. If you have been told that net metering in British Columbia is closed, that statement is true of BC Hydro and false of FortisBC.
The rate you pay is also different in shape, not just in number. Residential customers bill on Rate Schedule 1, which is flat: 15.503 cents per kWh with no tiers, effective 1 January 2026 under BCUC Order G-293-25. The customer charge is $49.58 per two month period, which works out to about $24.79 a month, and it is worth reading it that way because FortisBC bills bimonthly, so the charge appears once on a bill covering two months rather than once a month. And there is no residential time of use option to weigh: Rate Schedule 2A, the residential time of use schedule, is closed to new customers, so no FortisBC residential customer can be billed at on peak or off peak rates today.
What a flat rate and open net metering mean for sizing
A flat rate simplifies solar design considerably. There is no tier to stay under and no peak period to dodge, so a kilowatt hour saved at noon in July is worth the same as one saved at seven in the evening in January. That removes most of the reason to time appliances, shift EV charging or otherwise chase the rate, which is a real difference from how a BC Hydro customer now has to think.
Net metering under Schedule 95 removes the other complication. Because surplus generation is handled through the net metering program rather than converted into a low fixed export credit, sizing to your annual consumption is a defensible approach in Kelowna in a way it no longer is on the coast. That does not mean bigger is automatically better: an array sized well past what your household actually uses over a year is still capital you are unlikely to recover, and how a persistent annual surplus is treated is a question to put to FortisBC directly for your own account before you finalise a size.
Storage looks different here for the same reason. Where the value of a battery on a BC Hydro account now comes partly from avoiding a low export credit, a Kelowna homeowner on flat rate net metering has no rate spread to arbitrage: charging a battery at noon and discharging at night saves nothing on a rate that does not change with the hour. That leaves outage backup as the honest reason to buy one. It can be a good reason, but it should be weighed as a resilience purchase rather than a bill saving one.
One more piece of the bill is worth understanding before you size anything. The customer charge, $49.58 per two month period, is attached to the account and does not move with consumption, so it stays on the bill regardless of how well the array performs. Solar reduces the energy portion of a FortisBC bill. It does not close the account.
Your roof, and Kelowna's ground oriented housing
Kelowna has 62,210 dwellings and the stock is dominated by homes with roofs their owners control. Single detached houses alone are 42.5%, the largest category by a clear margin. Duplexes add 10.7%, row houses 7.9% and semi detached homes 4.9%. High rise apartments are rare here, just 3.9% of the stock. Rutland, Glenmore, Mission and the North End are among the neighbourhoods the city identifies.
That mix matters because the biggest obstacle to residential solar in denser cities is not engineering, it is permission. Where the roof is common property, an array becomes a strata project with its own approval process, budget and timeline. In Kelowna, most homeowners simply do not face that step, which shortens the path from decision to installation considerably.
The checks that remain are practical. Confirm the roof covering has enough remaining life that you will not be paying to remove and reinstall the array partway through: panels outlast shingles, so re-covering first is cheaper than doing it later. Check midday shading on the planes you would use, across the seasons rather than on the day of the site visit. And have the electrical service assessed, because the main panel has to accommodate a back fed breaker sized for the inverter, and a service upgrade found late is the most common reason a quoted price changes.
Being on the Heritage Register is not a restriction
Kelowna draws a clear line here, and it works in a homeowner's favour. Listing on the Kelowna Heritage Register does not constitute heritage designation and does not limit the development potential of the property. Listed buildings can be altered. The only practical consequence attached to a Register listing is that Council may briefly delay a demolition permit, which has nothing to do with putting panels on a roof.
The Abbott Street Heritage Conservation Area is the separate case. Properties inside its boundary face additional review for exterior work, so if your address is in that area, confirm what applies to a roof mounted array before you commission a design. For every other Kelowna homeowner, including those whose houses appear on the Register, heritage rules are not a barrier to solar.
Rebates and financing, and a caveat for FortisBC customers
Here is where being a FortisBC customer needs care rather than assumption. The headline residential solar incentive in British Columbia is a BC Hydro program: BC Hydro offers up to $5,000 for residential solar, at $1,000 per kW of installed generator capacity capped at 50% of the total installed cost, plus battery incentives of $500 per kWh up to $1,500, or up to $5,000 with Peak Saver enrollment. Since it is a BC Hydro program and Kelowna is a FortisBC service area, do not assume it applies to your account. Ask FortisBC directly what incentives are available to you before you build any rebate into a budget, and treat any installer who quotes you a BC Hydro rebate without checking as a reason for a second opinion.
Federal programs apply regardless of which utility serves you, and there is less of them than there was. The Canada Greener Homes Loan, interest free up to $40,000, stopped accepting new applications on 2 October 2025 and only previously approved loans are still being funded. Its replacement, the Canada Greener Homes Affordability Program, delivers no cost retrofits through provincial partners for low to median income households; solar counts as eligible federally, though the technology list is settled province by province. Canada has no federal investment tax credit for residential solar, so any quote built around one is borrowing American numbers.
On sales tax, British Columbia has at times exempted qualifying solar and renewable energy equipment from provincial sales tax. The scope and eligibility change with provincial budgets, so confirm the current PST treatment of your specific equipment at the time of purchase rather than relying on what applied to someone else's system last year.
