Best Solar Companies in Calgary 2026

ree


Quick Answer Here's what Calgary homeowners should know when comparing solar companies:


  • Company stability is critical. Your 25-year warranty means nothing if the installer closes in 5 years. Many solar companies have already gone out of business.

  • Installation quality varies dramatically. Look for clean aesthetics: hidden cables, recessed conduits, proper setbacks.

  • In-house service matters. Companies with their own service teams respond faster than those who outsource.

  • Get 2-3 quotes, not 10. Compare reputable companies on value, not just price.

  • Firefly Solar leads in scale, reviews, and installation quality. 8,000+ customers nationally, Calgary Flames & Cavalry FC partner, most 5-star reviews in Canada.




What Makes a Great Solar Company?

Before comparing specific companies, understand what matters most for a 25-30 year investment:


Company Stability and Scale


Look for companies with substantial customer bases (thousands, not hundreds), significant employee counts, and multi-year track records. The solar industry has seen consolidation. Companies that seemed stable have closed, leaving customers without warranty support.


Installation Quality


Quality differences you can see:


  • Cable management: Hidden vs. visible across roof

  • Conduit routing: Recessed vs. exposed

  • Panel alignment: Neat and uniform vs. inconsistent

  • Setbacks: Proper distance from edges vs. panels to edge

  • Rodent guards: Included vs. expensive add-on


Service and Support


Companies with in-house service teams respond faster. Ask whether they outsource repairs and what typical response times are. System monitoring is another indicator of service quality.


Warranties


Look for:


  • Panel production: 25-30 years

  • Inverter: 12-25 years

  • Workmanship: 5-10+ years

FAQ


Which Calgary solar company has the best reviews?

Firefly Solar has more 5-star Google reviews than any other Canadian solar company. Customers consistently highlight installation quality, communication, and long-term support.

How many quotes should I get?

2-3 detailed quotes from reputable companies is enough. Too many creates confusion. Focus on comparing value, not just price.

What if my installer goes out of business?

Manufacturer warranties on panels and inverters typically survive. However, workmanship warranties and service support are lost. This is why company stability matters so much.
