How do Suntech solar panels compare in the modern era?

Suntech Solar Panels by Perth Solar Warehouse

If there’s anything you should take away from this post today, it’s that Suntech is one of the most significant technological developments to come out of Australia in recent history. More than just another BNEF Tier-1 solar panel manufacturer, Suntech solar panels are designed to perform in the enduring Australian conditions, while founded off the back of Australian ingenuity and investment.

All seems well and good having an Australian founded and designed product history, although, what does this mean if Suntech solar panels are not Australian-made? Truth be told, a lot more than many would expect. 

Despite a financial blip over a decade ago, Suntech has been resurrected and remains one of the few solar panel manufacturers who continue to invest millions into the Australian economy through renewable energy R&D in collaboration with well known and respected Australian universities. 

Suntech has become an evolved brand perfectly adapted to the new world. There is no doubt the connection between Suntech and Australia is as strong as the brand’s inception two decades ago.

Which to consider

60-cell or 120 half-cut cell Suntech solar panels are where 97% of residential homeowners should be looking. Therefore, considering such, there is some exceptional value to be had within the Suntech range.

Almost all Suntech 60-cell polycrystalline solar panel variants have been exhausted locally, therefore, we’ll stick to listing only the available monocrystalline variants.

What is the warranty

As one of the original solar panel manufacturers to boast a 15 & 25-year warranty, it appears to have become a new norm for many solar panel manufacturers to separate themselves from the pack. In a nutshell, the Suntech solar panels warranty is broken up into two.

Performance warranty defines the rated output degradation (subject to Standard Test Conditions) overtime should the module remain intact. Suntech solar panels are accompanied by a 25-year linear performance guarantee which states the solar panel shall not degrade by more than 0.7% per annum after the first year at standard test conditions.

Where are they made

Predominantly in multiple branches across China depending on the specific module type. However, did you know that Suntech also has manufacturing facilities in Germany and Japan? 

It’s fair to say that the Suntech solar panels installed in Australia are derived though from Suntech’s fully automated production facilities in China. A well publicised, high-quality manufacturing line which presents exceptional value for the final product produced.

Internationally though, Suntech’s global support spans the essential continents where widespread distribution exists for the product:

  • NSW, Australia.
  • Dubai, U.A.E.
  • South Africa.
  • Hong Kong.
  • Germany, Europe.
  • Wuxi, China.

What do they cost

Suntech solar panel options resonate with premium customers seeking good technology value. A BNEF Top 20 [Q2, 2024] manufacturer globally, all currently produced Suntech Solar panels must push innovative boundaries or remain on trend to compete with similar high-volume manufacturers. However, you’re purchasing more than a solar panel and investing in a brand that is more likely to have warranty assurance for the intended period. Expect competitive value for the technology inside.
