Strathmore's yield, and how to size a system against it
At about 1,315 kWh a year per installed kW, Strathmore sits at the stronger end of what NRCan models across central Alberta. A 7.5 kW array on that basis works out near 9,900 kWh a year, and a 10 kW array near 13,200 kWh, before shade, snow and equipment losses are deducted. Those are modelled figures for a fixed array at sensible tilt and orientation, not a promise about any particular roof.
A higher yield per kilowatt is genuinely useful, because it means fewer panels for the same annual output, which reduces both the hardware cost and the amount of clear roof you have to find. It does not change the shape of the year. Production still concentrates between spring and early autumn, still falls away through the short days of December and January, and still depends far more on shading and orientation than on which Alberta town you live in.
Design to your consumption rather than to your roof area. Because of the export rules covered below, the last few panels that push a system past your household's annual use earn less per kilowatt hour than the first ones do. Bring a year of bills to the conversation and ask for production modelled month by month against them, which is also the only way to see how much of your winter load the array will never cover.
FortisAlberta connects you, your retailer pays you
Strathmore's distribution utility is FortisAlberta Inc. It owns the local wires and handles the microgeneration interconnection, applied for and tracked through the PowerClerk portal it runs for that programme. That application deals with the physical side of the project: how large the system is, what equipment it uses, and when it may be energised.
Who you buy electricity from is a separate decision, and in Alberta's deregulated market it is genuinely yours to make. The retailer is the party that credits the power you export, on terms negotiated with it, so two identical systems on identical Strathmore roofs can be worth different amounts depending on which contract sits behind them. Compare micro-generation terms as carefully as you compare panel quotes.
A practical note: changing retailer does not require touching the FortisAlberta connection, so a poor micro-generation contract is not a permanent condition. Before signing one, check the term, any exit fees, and whether the micro-generation credit is fixed or tracks a floating rate.
Why an exported kilowatt hour is worth less than an imported one
Alberta credits micro-generation exports at your retailer's energy rate and at nothing more. The bill for what you import adds transmission and distribution charges, riders and local access charges on top of that same energy rate, and export credits never reach those lines. Calling this one for one net metering would be wrong, and understanding the difference is the single most important input into choosing a system size.
There are no peak or off-peak hours to plan around here either, because Alberta has no province-wide residential time-of-use tariff. The only timing question that matters is whether a load runs while the array is producing. Every load moved into daylight avoids the fully delivered rate instead of earning the smaller export credit, which is why the cheapest efficiency measure available to a solar owner in this town costs nothing at all.
Storage earns its keep on the same logic rather than on any special rate. A battery charged from your own midday surplus supplies the evening at the price you would otherwise pay for delivered electricity, and that is worth more per kilowatt hour than exporting the surplus would have been. It is also a real capital cost, so ask to see the case with and without it, run against your own consumption data.
Any credit left over at year end must be paid out in cash by the retailer rather than carried forward. Between that and the gap between the energy rate and the delivered rate, a system matched to your consumption usually beats a maximum-size one in Strathmore.
Permits, and the setback and height question
Strathmore's residential permit page sets out where a Development Permit and Building Permit are required: decks over 0.6 m, secondary suites, and new low-density or multi-residential construction. It also states the rule that matters most for a solar project, which is that renovations that do not increase a building's area, and that comply with land-use setback and height rules, may not need a Development Permit.
Read that against your actual design. A flush roof-mounted array adds no floor area, but a tilted rack raises the highest point of the structure, and a ground-mounted array is a structure in the yard subject to setbacks. Those are the cases where the answer can change, and they are far cheaper to resolve before hardware is ordered than afterwards.
Solar is not addressed separately anywhere on that page, so the town asks you to contact development@strathmore.ca to confirm what your project requires. Do it in writing and keep the reply with your file. Strathmore publishes no review turnaround for these applications, which means there is no service standard to hold anyone to and no basis on which an installer can promise an approval date.
Your roof, and the guidelines that are not in the bylaw
Alberta has no US-style homeowners associations, but the town's own guidance notes something close enough to matter: some Strathmore neighbourhoods carry architectural guidelines that add restrictions beyond the general municipal bylaw, fence height being the example the town itself gives. These are private instruments, they differ from one subdivision to the next, and they will not turn up in a municipal permit search. If your neighbourhood has them, read them before choosing panel colour, array layout or a tilted rack.
The housing mix decides who else gets a say. Single-detached houses are 58.6% of dwellings, so most owners here control their own roof. Semi-detached at 12.7% and row housing at 10.1% together make up close to a quarter of the town, where the roofline is shared or adjoining and a condominium bylaw commonly governs anything that alters the exterior. Low-rise apartments account for 13.4%, where a landlord or a board decides, and duplexes for 1.1%. No high-rise buildings appear in the mix.
On the building itself the questions are the ordinary ones, and they are worth settling early: how much life the shingles have left, whether the roof structure carries an array plus snow, how much of the best plane is broken up by vents and stacks, and whether the electrical service has capacity for the interconnection without an upgrade. Any of these can change a price after a site visit, so treat a quote issued without one as provisional.
Financing, rebates and what federal programmes now cover
There is no federal tax credit for residential solar in Canada, so the help available in Strathmore is provincial and municipal in character. The Clean Energy Improvement Program is the main financing route: roughly $3,000 to $50,000 of solar and efficiency work, repaid through the property tax bill at a fixed rate set by the participating municipality, over terms of up to 25 years.
Participation is the first thing to check, since the programme operates only where a municipality has adopted it and the published roster names Calgary, Edmonton, Canmore and Lethbridge among more than twenty. Ask the town whether an intake is open before treating that financing as available to you.
Municipal rebates are the volatile layer. Communities elsewhere in Alberta have offered something in the order of $200 to $450 per kW, with caps in the $1,000 to $15,000 range, and those windows open and close on short notice. Verify anything a salesperson quotes with the municipality itself rather than with the person quoting it.
Federally, the interest-free Canada Greener Homes Loan of up to $40,000 stopped accepting applications on 2 October 2025 and now pays out only on approvals already granted. The Canada Greener Homes Affordability Program replaced it in September 2025, working through participating provinces, which do not currently include Alberta, to deliver no-cost retrofits for low to median income households, with solar eligible at the federal level and each province setting its own list of technologies.
