FAQS about The difference between solar panels q1 and q2

What is the difference between Tier 1 and Tier 2 solar panels?

Tier 1 solar panels come from manufacturers that use top-quality materials and provide better warranties. Typically, they offer a 12-year product warranty and a 25-year linear performance warranty. Tier 2 solar panels have shorter warranties and possibly less durability due to their lower-quality materials.

Are Tier 1 solar panels more expensive?

However, with Tier 1 solar panels, the chances of the solar panels having defects are lower. Tier 1 solar panels are typically 10-30% more expensive than Tier 2 solar panels. Are Tier 1 solar panels worth it?

Should I Choose Tier 1 or Tier 2 panels?

If your project is a significant one, Tier 1 is the way to go. Tier 2 Panels: Now, Tier 2 can be a cost-effective choice. But don’t jump in just yet; take your time to research the brands and their warranties. Some Tier 2 options hold their own against their Tier 1 counterparts, but choose wisely. Tier 3 Panels: It’s best to steer clear from these.

Are there any Tier 2 or Tier 3 solar companies?

As such, there are no official lists of Tier 2 or Tier 3 solar companies. However, people in the solar industry needed an easy term to describe all the non-Tier 1 manufacturers, and Tier 2 is the unofficial catch-all term that’s used. Tier 1 solar manufacturers are believed to make up no more than 2% of all solar manufacturers in the business.
