The Ultimate Canadian Solar Installer Vetting Checklist

Introduction

Choosing the right solar installer in Canada is half the battle—and it can make or break your clean energy investment.

With dozens of companies vying for your business (some good, some… not so much), you need a clear way to compare quotes, verify credentials, and spot red flags. That’s where this solar installer vetting checklist comes in.

Use this step-by-step guide to confidently choose a contractor who will deliver on their promises—and help you avoid costly mistakes.

Verify Credentials and Licensing

Make sure your installer is legally allowed to work in your province and has the right certifications.

Ask for:

• Electrical license (Red Seal or provincial equivalent)
• CSA-approved solar installation training
• HRAI or TECA certification (for HVAC/heat pumps)
• Active business licence and GST number
• Proof of general liability insurance ($2M+)
• Workers’ compensation coverage (WSIB, WCB, CNESST, etc.)

Tip: Use provincial lookup tools like ESA (Ontario) or Technical Safety BC.

Check Reviews and References

A good contractor should have a track record of satisfied customers, especially in your region.

Ask for:

• At least 2–3 homeowner references nearby
• Recent Google or SolarReviews ratings
• Photo gallery of past installations

Red flags:

• Franchise with no local install examples
• All 5-star reviews from unverified accounts
• No photos or location-specific case studies

Get a Transparent Quote

Every solar quote should include:

• Panel brand, model, and wattage
• Inverter type and specs
• Expected annual energy output (in kWh)
• System layout or design mockup
• Total cost (pre- and post-rebate)
• Any optional upgrades (batteries, EV chargers)

Tip: If a quote only lists “6 kW system – $20,000” without details—ask for a full breakdown.

Ask About Permits and Paperwork

Installing solar in Canada requires municipal and utility approvals.

Ask:

• “Who files the electrical and building permits?”
• “Do you handle net metering applications?”
• “Will I receive a copy of the final inspection?”

A good installer manages this from end to end and includes it in your project cost.

Understand the Warranties

You should receive three kinds of warranties, in writing:

Warranty Type	Covers	Duration
Product Warranty	Panels, inverters	10–25 years
Performance Warranty	Panel output vs. degradation	25 years
Workmanship Warranty	Labour and installation	1–2 years

Tip: Confirm if the installer handles claims or if you must contact the manufacturer.

Confirm Payment Schedule and Financing Terms

Avoid large upfront payments without milestones.

Standard structure:

• 10–15% deposit upon contract signing
• 50% after permits or materials delivery
• Balance on inspection or commissioning

Ask:

• “Are there payment escalators in the financing?”
• “Can I cancel the loan if the install is delayed?”

Red flag: Pressure to sign without time to review financing documents.

Ask About Aftercare and Monitoring

Ask:

• “What happens if my inverter fails in year 3?”
• “Is performance monitoring included?”
• “Do you offer annual check-ups or service calls?”

Most modern systems offer free lifetime monitoring via app or browser.

Bonus Tip: Ask for a walkthrough of the monitoring platform before install.

Red Flag Checklist: Walk Away If…

• You’re pressured to sign same-day
• The quote is missing specs or performance data
• The company can’t provide insurance or license proof
• Verbal promises aren’t backed up in writing
• Permits or inspections are “your responsibility”
• Financing terms are buried or unclear
