Unravelling the Truth Behind "Tier 1" Solar Panels: Look Beyond the Label

The infamous "Tier 1" label can often cause some confusion in the solar industry. As a reputable solar installation company, we believe in transparency and equipping our customers with the right knowledge. In this post, we’ll explore what "Tier 1" actually means and why it's vital to dig deeper when choosing solar panels for your green energy journey.

Unravelling the Tier 1 Mystique:

You may have come across the term "Tier 1" when researching solar panels, and it's natural to assume that it signifies top-notch quality. However, the truth may surprise you. "Tier 1" is primarily a rating that reflects a solar panel manufacturer's financial stability and production capacity. It’s not directly related to the quality or performance of the solar panels themselves.

Not all "Tier 1" panels are created equal. While two solar panels may carry the same label, their performance characteristics can vary significantly. This is where spec sheets play a crucial role. By comparing spec sheets, you gain insight into each panel's capabilities, enabling you to make an informed decision aligned with your unique energy needs.

Standard Test Conditions:

Solar panels are tested under standardised conditions to rate the panel performance in a controlled environment. Panel manufacturers then issue spec sheets based on the outcomes of this testing. This then allows consumers to compare panels like-for-like by looking at the panel spec sheet. In particular, consumers should consider the efficiency rating as a good starting point. We recommend speaking with a CEC-certified installer and designer to help you understand how panels differ and may be suitable for your particular needs.

Looking Beyond the Label:

When choosing solar panels for your home or business, remember these key steps:

Analyse the Spec Sheet: Dive into the technical specifications of each solar panel. Pay close attention to efficiency, degradation rate, temperature, and warranty terms.

Check the Warranty Documents: Many manufacturers have limited warranties or clauses to exempt them from paying out in the event of a common fault. Check the warranty documentation in detail and consider that a more comprehensive or longer-duration warranty could represent better value.

Location Matters: Consider your geographical location and climate. Different panels may perform better under specific conditions.

Speak with a CEC-certified installer or designer: The best way to make sure you’re getting the right system is to speak to a qualified installer who has taken the time to attend an on-site inspection and assess your needs.
