TIER 1 PANELS
There are several criteria involved in determining what tier a solar panel is classed as. In this day and age there isn’t much difference in terms of energy performance between Tier 1, 2 and 3 solar panels. However, the rating system is still useful for determining which companies may produce better quality products and, importantly, which companies seem more likely to still be in operation if you need to make a warranty claim.
Remember, most solar panels come with a 25 year output warranty, but your warranty wont mean much if the company that issued it doesn’t exist anymore! That is why one of the criteria of Tier 1 panels is that the manufacturer has been in business for more than 5 years.
As the solar industry is relatively young, 5 years is a long time and many solar businesses in Australia and overseas do not last more than 1 or 2 years. In fact, Sun Gods Solar is one of the longest running solar companies on the Gold Coast!
