What a Fort McMurray roof actually produces
NRCan's photovoltaic potential dataset models a well-oriented fixed array in Fort McMurray at about 1,179 kWh a year for every kW installed. On a 7 kW system that is roughly 8,300 kWh in a modelled year, before shading, snow cover and equipment losses are subtracted. Judge a design on that annual figure, because this far north the seasonal spread is extreme: the array does most of its work in a long stretch of summer daylight and very little in the short days at the other end of the year.
That seasonality has a practical consequence for sizing. A system scaled to cover a winter bill would be enormous and would spill most of its summer output onto the grid at export value, which in Alberta is the lower value. Sizing to annual consumption, and accepting that summer covers winter on paper rather than in real time, is the usual approach.
The design fundamentals are unchanged: south-facing planes collect the most over a year, east and west planes trade some annual total for a wider daily spread, north faces rarely justify the hardware, and midday shade from a chimney or a neighbouring roof costs more than its footprint because panels in a series string follow the worst-lit one. Snow on the glass stops a panel until it clears, which the annual model already assumes for some days.
ATCO Electric owns the wires, someone else sells you power
ATCO Electric Ltd. holds the exclusive electric distribution franchise for the Regional Municipality of Wood Buffalo, renewed in 2025 for a further term of roughly ten years. That makes ATCO the wires company your solar connection goes through, and it is not a choice: the franchise is geographic.
Your retailer is a different matter. Under Alberta's deregulated market, the company that bills you for the electricity itself is separate from the one that owns the poles, and you can change it. That distinction matters more for solar than for anything else on your bill, because it is the retailer contract, not ATCO, that sets what your exported power is credited at.
How Alberta credits the power you export
Under Alberta's Micro-generation Regulation, exported electricity is credited monthly at your retailer's energy rate. Every kilowatt hour you import is billed at that energy rate plus transmission, distribution, riders and local access charges, and the export credit never offsets those. So an exported kilowatt hour is worth materially less than an imported one. This is not one for one net metering, whatever a sales sheet calls it.
Alberta also has no province-wide residential time-of-use rate, so there is no expensive period to avoid and no cheap one to shift into. The only rate advantage available is using your own generation as it is produced. That is worth designing around in a house with electric heat, a hot tub, or an EV, because moving those loads into daylight hours converts export-value energy into avoided full-rate energy.
The credit rate is negotiated between you and your retailer rather than fixed by the province, so micro-generation terms are worth comparing between retailers line by line before signing. Unused credits are paid out in cash at year end rather than rolling forward indefinitely, and the regulation's 5 MW ceiling has no bearing on a house, so your system size comes from your consumption and your roof.
Two permits, and why you cannot install it yourself
In the Regional Municipality of Wood Buffalo a homeowner cannot self-install a solar photovoltaic system. A licensed electrical contractor must pull the Electrical Permit and do the work, following the Municipality's own Solar Photovoltaic Guidelines and its Structural Review Checklist for the mounting system. If you were planning a weekend project to save on labour, that option is closed here, and any quote should be from a contractor who can hold the permit.
The Municipality states that once a complete application is received, electrical permit processing takes three to five business days. Read that carefully: it describes the electrical permit alone. The same Solar Photovoltaic Guidelines also call for a conditional Building Permit, which the Municipality lists at five to fifteen business days, and a solar project needs both. Presenting the electrical figure as the time from application to approval understates the wait, and it is a common error in national installer marketing.
So plan on two sequential approvals rather than one, and treat the structural side as the one more likely to raise questions. The Structural Review Checklist exists because a roof carrying an array plus accumulated snow is a structural question, not a cosmetic one, and an incomplete submission is what turns a short review into a long one.
Your roof, and what the local housing mix means
One caveat before the numbers: Statistics Canada does not report Fort McMurray separately, so the housing figures here describe the Regional Municipality of Wood Buffalo as a whole. Fort McMurray is the great majority of that population, so the mix is close but not an exact match for the urban service area alone.
On that basis, about 48% of occupied private dwellings are single-detached, which is still the largest category and the case where one owner controls the roof and the permits. Low-rise apartments are about 22%, a large share, and there the decision belongs to a landlord or a condominium corporation rather than to a resident. Row houses are about 11% and high-rise apartments about 3%.
For a detached home the questions are the usual ones, with a northern emphasis: shingle age and remaining life, structural capacity for panels plus snow load, and how much of the best roof plane is already taken by vents and stacks. For row houses the array is usually smaller because the south-facing section is narrower and shared along the block, and exterior changes fall under the condominium bylaw where one applies.
Financing and programs to check first
Alberta's main financing route is the Clean Energy Improvement Program, which finances roughly $3,000 to $50,000 of solar and efficiency work through the property tax bill at a fixed rate set by the municipality, over a term of up to 25 years. It runs only in participating municipalities, and the program's own list names Calgary, Edmonton, Canmore and Lethbridge among more than twenty, so check directly whether it is offered where you live before counting on it.
Municipal solar rebates elsewhere in the province have historically run around $200 to $450 per kW with caps between $1,000 and $15,000, but they vary by community and change often, so confirm the current position rather than relying on a figure in a brochure.
Federally, the Canada Greener Homes Loan stopped accepting new applications on 2 October 2025 and now funds only previously approved loans. The Canada Greener Homes Affordability Program that replaced it delivers no-cost retrofits through participating provinces, which do not currently include Alberta, for low- to median-income households, with solar PV eligible federally but each province setting its own technology list. Canada has no residential investment tax credit equivalent to the American one, so no quote here should assume a federal percentage back.
