Solar Panel Companies: Smart, Friendly Nova Scotia Guide

Author: Mariela Guanchez

 

When you compare solar panel companies in Nova Scotia, the goal isn’t to memorize codes or decode sales talk—it’s to make sure your system is safe, approved the first time, and produces what you expect. Let’s keep it friendly and simple, like advice from a neighbor who’s done it before.

 

What to look for in solar panel companies

Start with the basics and you’ll breathe easier later.

• Permits & inspection, handled for you. Your installer should obtain the wiring permit and schedule the electrical inspection with Nova Scotia Power. If this process isn’t clear in the proposal, that’s a red flag.
  Official steps: NS Power Electrical Inspections 
• Approved equipment. Ask for proof that modules and inverters are CSA/ULC-certified for use in Canada. Otherwise, the installation simply won’t pass inspection. 
• Plain-English design. A good proposal explains orientation, tilt, shading, expected losses—and gives you a reasonable annual kWh estimate for your address. 
• Written warranties. Separate product, performance, and workmanship. Clear, short, and in writing. 

Altogether, solid solar panel companies make each step obvious, with no fine print or guesswork.

 

Rules solar panel companies should respect (without you learning the rulebook)

You don’t have to speak “code”—just know these anchors:

• Electrical inspection by NS Power. Every residential system is inspected. Good installers walk you through it up front and include it in their schedule. 
• Canadian certification (CSA/ULC). Certification labels matter; they’re what allow the inspector to approve the job. 
• Building Code basics. Roof attachments, waterproofing, and wind/snow considerations should meet the Nova Scotia Building Code. Ask how they’ll protect your roof and show you the hardware plan. 
• Net metering explained clearly. You’ll self-consume solar during the day and draw from the grid when you need it; credits help balance things out across the year. Your installer should explain how your bill will look—no jargon required. 

Warranties that actually matter (read them in five minutes)

Think in three boxes:

1. Product (modules & inverter): covers manufacturing defects. 
2. Performance (linear): guarantees a minimum power after 25–30 years (you’ll often see ~1% allowance in year one, then ~0.4–0.5%/year). What matters is that the curve is written into the contract. 
3. Workmanship (installer): who pays if there’s a visit, how tickets are handled, and for how long you’re covered. 

Tip: if a warranty isn’t crystal clear in the contract, ask for the exact wording before you sign.

 

Design & estimate: sanity-check kWh in one minute

Don’t rely on promises alone. Use the official NRCan map to see typical kWh per kW-year for your location in Nova Scotia. If a proposal claims way above that range without a strong, documented reason, ask why.

A quick check with this map keeps expectations realistic and your decision calm and confident.

 

Red flags when choosing solar panel companies

• Silence on permits/inspection. If they don’t mention the NS Power inspection process and who handles it, be cautious. 
• No CSA/ULC labels. If they can’t show Canadian certification for the equipment, walk away. 
• “Magic” production numbers. Big kWh claims far beyond what NRCan suggests—without a clear design reason—are a warning sign. 

Quick checklist (save this to your notes)

• Permits & inspection included (who handles what and when). 
• CSA/ULC-certified equipment (proof provided). 
• Annual production cross-checked with NRCan. 
• Warranties in writing: product, performance, workmanship. 
• Roof plan that meets Building Code (attachments + waterproofing). 
• Net metering explained in plain English (how credits show up on your bill).
