You’ve been told to buy “Tier 1” solar panels… but what does Tier 1 actually mean?

With more than 100 solar panel and inverter manufacturers competing for attention, choosing the right hardware can quickly become confusing.

In this episode of Charged Up, Simon Wray and Justin Canning cut through the marketing and explain what homeowners and businesses should actually look for when comparing solar brands.

One of the biggest misconceptions? Tier 1 doesn’t necessarily mean better quality.

Tier 1 is largely a measure of a manufacturer’s financial strength, track record, production scale and bankability. It can be useful — particularly on large, financed solar projects — but it doesn’t automatically tell you which panel will perform best on your roof.

The takeaway is simple: don’t choose solar hardware based purely on a logo, headline efficiency figure or “Tier 1” badge.

Understand why your installer is recommending that particular equipment — and make sure the system is right for your property, budget and long-term requirements.
