What a Saanich roof produces in a year
The modelled yield for Saanich is about 1,080 kWh a year for each kW of installed panel capacity, on a well oriented array with clear sky access. In round numbers that is 5,400 kWh from a 5 kW system, 6,500 kWh from 6 kW, 8,600 kWh from 8 kW and 10,800 kWh from 10 kW. Those figures describe an idealised roof, so treat them as a way of testing whether a quoted projection is reasonable rather than as a commitment about your own house.
What separates a real roof from the modelled one is mostly direction and obstruction. A south facing plane collects the highest annual total; east and west planes give up part of that in exchange for producing across more hours of the day, which is a more useful trade under the export rules described below than it used to be. Usable area is what remains after vents, plumbing stacks, skylights and edge clearances are subtracted, and shading has to be measured on site, because one shaded module can drag an entire string down unless the design isolates panels with microinverters or optimisers.
The annual figure also hides seasonality. Production concentrates in the long days on either side of midsummer and drops sharply under winter overcast, while your household's consumption has its own shape. The value of a system depends on how well the two overlap, not on whether the annual totals match.
The rate you are on by default, and the one you are not
Saanich homes connect to BC Hydro, and there are two facts about that account worth getting straight before anyone quotes you a system. The first is what rate you are on. BC Hydro does offer time of day pricing, but it is opt in, and the default residential rate is still the tiered one. Installing solar does not move you onto peak and off peak prices, and nothing about a solar application enrols you. That means guidance about timing your generation to hit expensive hours does not describe your bill unless you have gone out of your way to change rates.
The second is what happens to what you export. BC Hydro closed Rate Schedule 1289, its net metering rate, to new customers on 1 July 2026. New systems connect under Rate Schedule 2289, the self generation rate, where a surplus left at the end of a billing period is converted into a bill credit at a fixed 10 cents per kWh, applied against energy charges, for systems up to 100 kW. Your panels still supply the house first, and generation is still netted against consumption inside the billing period, so an array only counts as exporting once it has covered what the house is drawing at that moment. Existing net metering customers are not moved on the change date: they keep Rate Schedule 1289 until ten years from their own service start date.
Put those two facts together and the design conclusion follows without much arithmetic. Because you are on the tiered rate rather than a time of day one, there is no expensive hour to aim for, so the only lever that changes the value of a kilowatt hour is whether it is consumed in the house or sent to the grid. And because 10 cents sits below the residential energy rate, the consumed one is worth more. Sizing to your annual consumption, which made sense while surplus kilowatt hours could be banked, now overshoots. Sizing to what the household draws during daylight, and moving flexible load into those hours where you can, is the version that matches the rate you are actually on.
What Saanich charges, and the deposit you get back
Saanich prices building permits from a formula rather than a flat fee: $100 for the first $1,000 of construction value, plus $13 for each additional $1,000 up to $500,000, and $10 per $1,000 above that. A residential rooftop array never reaches the upper tier, so the fee simply scales with the declared value of your project. The useful consequence is that it is predictable: once you know the contract value, you can work out the permit cost before you apply, and a larger installation carries a proportionally larger fee.
The part that catches homeowners out is the surety deposit, because it is money you hand over and get back. Saanich takes a refundable deposit of $1,000 on single family additions or alterations, and $2,000 on new single family homes. A rooftop solar installation on an existing house is an alteration, so plan on the $1,000 being tied up for the duration of the work. It is a cash flow item rather than a cost, but it is real money out of the account while the project runs, and it belongs in your budget alongside the equipment and the labour.
Electrical and gas permits are not Saanich's to issue. They are regulated separately by Technical Safety BC, which means a completed solar project involves the municipal building permit on one side and the electrical permit and inspection on the other, plus the interconnection application to BC Hydro running in parallel. Ask your installer to name who files each of the three and in what order. The delays in projects like this usually come from one approval waiting on another rather than from any single office being slow.
Being on the Heritage Register is not the same as being designated
Saanich has no US style homeowners associations, so there is no private board with authority over what appears on your roof. What exists instead is a heritage system, and the distinction inside it is the one that matters. The District's Heritage Register lists close to 300 properties. Just over 80 of those are protected by a Heritage Designation Bylaw, which is what actually restricts exterior changes.
Only the second group faces a legal constraint on a rooftop array. Appearing on the Register alone is a form of recognition, not a restriction on altering the exterior. If your address sits in the smaller designated group, exterior changes are controlled and a roof mounted array is exactly the kind of change that review exists for, so establish that before commissioning a layout rather than after. Against 48,045 dwellings, both numbers are small: the overwhelming majority of Saanich homeowners will never encounter a heritage step at all.
So put two separate questions to the District about your own address: is this property on the Register, and is it designated. Only the second answer changes what you are allowed to do. The same rules apply across the district, from Cordova Bay and Gordon Head through Royal Oak, Shelbourne, Tillicum and rural Saanich, so this is a per property question rather than a per neighbourhood one.
A housing stock split down the middle
Saanich's 48,045 dwellings are spread more evenly across housing types than most municipalities: 46.6% single detached, 21.5% duplex, 20.3% low rise apartment, 7.6% row house, 2.5% semi detached and 1.3% high rise. The net effect is that nearly as many households share a roof or a building as own one outright, so who holds authority over the roof surface is a genuine question here rather than a formality.
The duplex share, at 21.5%, is the striking one. A duplex normally puts two households under a single roof structure, so even a small array touches a plane your neighbour lives beneath. How the property is held decides the process: a strata titled duplex will usually treat that roof as common property and require an alteration approval before any work, while other arrangements leave the decision with individual owners. In either case, agree the mounting details, the flashing and the sequencing of any future reroof with the household next door before the panels are ordered.
Low rise apartments at 20.3% and high rise at 1.3% are unambiguous: the roof is common property and an array is a building project rather than a personal one, approved collectively, funded from the reserve or a levy, and sized against the building's shared consumption. Row houses at 7.6% are the ambiguous middle, since strata plans frequently treat the roof plane above a unit as common property even though the home feels detached.
For the 46.6% in single detached houses the decision belongs to you alone, and the checks that remain are physical rather than procedural. Confirm the roof covering has enough life left that you will not be paying to remove and refit the array to replace shingles underneath, and have the electrical service assessed, since the main panel needs to accept a back fed breaker sized to your inverter.
Rebates, and adding up what the project actually costs
The BC Hydro solar and battery rebate pays $1,000 for each kW of installed generator capacity to a maximum of $5,000, and never more than 50% of the total installed cost. That percentage test is measured against what the installation actually costs you, so it is worth assembling the real total before assuming the headline figure: equipment, labour, the permit fee from Saanich's formula, and any electrical work needed to bring the service up to standard. The refundable surety deposit is not a cost, but it is cash that has to be available at the right moment.
Storage is a separate calculation with its own rules. A battery paired with solar earns $500 per kWh up to $1,500, subject to a 5 kWh minimum and the same 50% ceiling, and that limit rises to as much as $5,000 where the battery is enrolled in Peak Saver. The economic case for storage under the current export rules is straightforward: a surplus sent to the grid returns 10 cents per kWh, while the same energy held and used in the evening avoids the retail energy rate, and the gap between those two is what a battery captures.
Two conditions attach to the rebate. Since 1 June 2026 the work must be carried out by a member of the Home Performance Contractor Network, so ask about membership while you are still comparing installers. And taking the rebate places you on the Self Generation Service rate, which is where a new Saanich connection begins in any case, so it only carries a real cost for a homeowner already holding the older net metering rate with grandfathered years left.
On the financing side, the Canada Greener Homes Loan, interest free up to $40,000, closed to new applications on 2 October 2025 and now funds only previously approved loans. The Canada Greener Homes Affordability Program replaced it, delivering no cost retrofits through provincial partners to low and median income households, with solar federally eligible though each province publishes its own technology list. No federal investment tax credit for residential solar exists in this country, so a projection that includes one has been lifted from the American market. British Columbia has at times exempted qualifying solar equipment from provincial sales tax, and since the scope shifts with provincial budgets, confirm the current PST treatment of your equipment when you purchase it.
