Choosing a solar installer in Calgary

What should a Calgary solar installer be able to show you?

Start with credentials, because solar panels connect to your house wiring and to the grid. In Alberta, electrical work normally has to be done by a licensed contractor under a permit, and the installer should be able to say who holds the permit and who will be on the roof. Ask for proof of liability insurance and workers' compensation coverage as well.

Then ask about experience in your area. A local installer should know the City of Calgary permit steps, the process for connecting to the local wires owner, and what inspectors expect. Our installer checklist lists the general questions, and the Alberta permits guide explains what the paperwork covers.

How do you design for Calgary's snow, wind and hail?

Calgary has bright winters, cold snaps, strong chinook winds and a real risk of hailstorms. These are the questions worth asking each installer.

• Is the racking rated for local wind and snow loads, and who checked that?
• What impact or hail rating do the proposed panels carry?
• Will the array be tilted enough to shed snow, and how does that change expected production?
• Is the roof old enough that it should be repaired or replaced first?

A flat, low-tilt array collects less in winter but looks tidier, so the trade-off should appear in the production estimate. The Calgary solar potential guide and the page on solar panels in winter explain what to expect through the year.

How should you compare solar quotes in Calgary?

Ask every installer to quote the same basics: system size in kilowatts, panel and inverter type, yearly production estimate, what is included in the price, and the payment schedule. Prices vary with roof, equipment and the season, and quotes decide the real number, so a company that refuses to put assumptions on paper is a poor sign. The quote comparison guide shows how to line quotes up, and price per watt gives a fair way to compare systems of different sizes.

Be cautious about very large savings claims or pressure to sign on the day. Production figures should come from a design based on your roof, with the shading and orientation stated. A high estimate with no assumptions is not a quote.

What do warranties, insurance and rules involve?

Read the warranty in two parts: the equipment warranty from the manufacturer, and the workmanship warranty from the installer. The second matters if the installer is gone in ten years, so ask how long the company has operated. Solar panel warranties explained breaks down what each type covers.

Tell your home insurer before the system is installed, and see home insurance after a solar install for what to ask. On the rules side, Alberta's micro-generation framework governs how a system connects and how surplus power is credited. It is summarized in the micro-generation regulation guide, but confirm current terms with the Alberta Utilities Commission, the provincial energy ministry and your utility.

Where do you find installers and check their record?

Start with the lists your utility or a provincial energy body may publish, then ask neighbours with systems about their experience, including how the installer handled problems after the job. Online reviews help, though they can be selective. Visit a completed local job if the company will arrange it.
