A Long-Term Investment
Solar is a multi-decade decision about your home. The real question is whether the numbers work for your roof and your usage — which is what a proposal is for.

Residential Solar · Guided Decision
See if solar makes sense for your home.
Solar is a long-term investment in your home, not a discount product — so this page is built to help you decide rather than to close you. Work through why homeowners look at it, whether your roof fits, and how a system actually gets designed.

Why Homeowners Look at Solar
Why Homeowners Look at Solar
The homeowners who end up happy with solar are usually the ones who were clear about why they wanted it. These are the reasons that hold up.
02
More Control
Generating some of your own power gives you a measure of control over a bill you currently just receive. It does not fix every component of that bill, or future rates.
03
Using the Roof You Have
A clear, well-oriented roof is an asset doing nothing today. Solar is one way to put it to work.
04
Timing It With Other Work
Homeowners often look at solar alongside a re-roof, an addition, or a new EV. The timing can matter as much as the system.
Section 02
Does Your Home Fit?
Does Your Home Fit?
Not every roof is a good candidate, and it is better to know early. Four things decide it:
01
Roof Orientation
South-facing roofs produce the most energy. East and west-facing roofs still work — expect roughly 10–15% less yield per panel, depending on pitch and shading.
02
Roof Condition
An array is a multi-decade addition to your roof. If your shingles have less than 10 years left, plan a re-roof first — we can coordinate.
03
Shading
Trees, chimneys, and neighbouring rooflines all cut production. Micro-inverters handle partial shade better than a string design does.
04
Usable Area
System size is bounded by the clear roof area you have, your annual consumption, and the limit your utility allows.
Conditions: the orientation and fit guidance above are planning rules of thumb. Your production figures come from a model built on your usage, address, and aerial imagery, and are an estimate of expected production — not guaranteed output. System size limits are set by current Alberta and utility rules and are confirmed during design.
Section 03
How Your System Gets Designed
How Your System Gets Designed
You do not need roof photos, measurements, or an energy rating. A recent bill and your address are enough for us to model a first design.
| Step | Action | Who Does It |
|---|---|---|
| 1 | Send a recent power bill + your address | You |
| 2 | K-Jay models the roof, design, and expected production | K-Jay Electric |
| 3 | Site visit, sizing choices, and proposal review | You + K-Jay Electric |
| 4 | Electrical permit + micro-generation application filed | K-Jay Electric |
| 5 | Install — racking, panels, inverter, tie-in | K-Jay Electric |
| 6 | Inspection, utility approval, activation | Your municipality + utility + K-Jay |
Conditions: timing varies with equipment, roof complexity, season, inspection, and utility approval, so this guide does not publish an install or activation date — your proposal gives the current expectation. Permit and interconnection steps depend on your municipality and your local distribution utility, and differ between Edmonton and the surrounding communities; K-Jay confirms which apply to your address during design.
Section 04
What We Specify, What We Estimate
What We Specify, What We Estimate
A proposal contains both hard specifications and modelled estimates, and it is worth knowing which is which before you compare quotes.
| Component | What We Specify | Manufacturer Warranty |
|---|---|---|
| Solar panels | Thornova Tangra M HD Black, 485–505 W N-type mono-crystalline (21.8–22.7% efficiency) | Up to 25 yr product · 30 yr linear power guarantee, max 0.40%/yr degradation |
| Micro-inverters | APsystems DS3-L | 25 yr — K-Jay includes the extended coverage on every system |
| Racking + roof attachments | Kinetic K-Rack with RoofTech RT-MINI II | Per manufacturer; attachment engineering is Alberta P.Eng stamped |
Conditions: this is the equipment we currently specify for a standard residential roof — the make and model on your system are the ones named in your proposal, which is the document that governs. Warranty terms are set by the manufacturers, not by K-Jay; the 25-year micro-inverter term is the extended option, which K-Jay purchases on every system rather than leaving it to you. APsystems requires the system to be monitored through their EMA portal for that coverage to stay in force, and monitoring is built into every design we do. Panel efficiency is a rated figure under standard test conditions; real output depends on the roof, shading, snow, and temperature.

Building a New Home?
Building a New Home?
Solar chosen during construction is a different decision, made through your builder rather than here — and it is usually the cleaner way to do it.
01
Choose It During the Build
Solar selected during construction goes on with the rest of the work, and the cost may be able to sit inside your mortgage. Ask your lender how that applies to you.
02
Or Rough It In
A solar rough-in during construction keeps the exterior cleaner for a later install, without committing to the full system now.
03
Ask Your Builder
You do not need roof details or an energy rating. Ask your builder's sales team for the solar option — K-Jay gathers the technical inputs from there.
04
Choose the Plan That Fits
Sizing is a conversation, not a single fixed package. Your builder's sales team walks you through the options for your home.
Conditions: new-home solar options, system sizing, and pricing are set through the builder path and confirmed by your builder's sales team, not on this page. Whether solar can be included in a mortgage depends on your lender and your financing, not on K-Jay.
Reviewed 24 August 2026 by K-Jay Electric. Equipment and warranty figures are taken from the manufacturers' current datasheets — Thornova TS-BBT54(485-505)-G11 rev. v20250721 and APsystems DS3 rev. 2.2 (2025-01-20). Production figures and any value marked * are estimates or typical values, not a quote, a specification, or a guarantee of output. Utility rules, regulations, product specifications, and manufacturer warranties change — the equipment, warranty terms, and timelines that apply to you are the ones written in your proposal. Next scheduled review: 24 February 2027.
