How to compare Solar Companies in London, ON

Start by assessing roof orientation, shading, and structural readiness before choosing panel types or financing. Compare installer proposals side by side—array layout, production estimates, warranty terms, and timelines—to see where assumptions differ. In a large regional city with steady residential demand, clear scopes and strong service commitments help distinguish quality bids from lookalikes.

What to compare first

  • Review average, review count, and whether the feedback looks consistent across enough customers to be meaningful.
  • Service fit for London, ON customers, including specialties, neighborhoods served, and the kinds of projects the business handles well.
  • Practical trust signals such as years in business, emergency availability, licensing, warranty details, and clear service categories when those details are shown.
  • Whether the listing explains what the business actually does, who it is a strong fit for, and how it compares to other local options beyond a single headline claim.
