Overview of Suntech Solar – Company History

Suntech Power was founded in 2001 by Dr Zhengrong Shi who is widely recognised as a pioneer of solar module manufacturing and dubbed as the “sun king” as he became the world’s first solar billionaire in 2006. Since commencing operations in 2001, Suntech has manufactured over 22GW of photovoltaic modules for more than 100 countries worldwide. During the period from 2001 to 2017, Suntech delivered 2.3 million photovoltaic modules to Australia alone. Suntech has developed a strong connection to the Australian market, with research and development projects being run at UNSW, ANU, and Monash University. These connections were enabled as founder and former CEO, Dr Shi obtained his doctorate degree of solar power technology at UNSW prior to founding Suntech.

In 2014 Suntech was acquired by Shunfeng International Clean Energy Limited, a renewable energy investment and independent power company. Suntech is focused on the innovation and production of high-performance solar panels. Suntech has received international recognition, being awarded Top PV Brand by the EuPD Research Institute. This is an illustrious award as EuPD is considered the solar industry’s leading research institute. Suntech has also received rewards from branches of the United Nations for its contribution to environmental protection.

What is a Bloomberg Tier 1 Solar Panel?

Bloomberg’s infamous tier 1 ranking is NOT a measure of Solar Panel quality in any way. It is simply an indication of the bankability of the manufacturer based on publicly released information on the financial health of the company. This should give you an idea if the company is a large, well-known manufacturer.

What is PV Evolution Labs Top Performer?

PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panel’s performance.

Why is office location in Australia Important?

Most solar panel manufacturers entering the Australian market first set up their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their 10-year product warranty.

Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing.

Suntech’s Australian head office is located in Chatswood, NSW.

Example of a Suntech Solar Commercial Solar Project

In 2019, Suntech supplied photovoltaic modules to a floating solar power plant. The plant located in Achern, Germany is currently the largest floating solar power plant in the country with the system totaling 750 kWp. The surface area of the solar power plant covers 2% of a man-made lake, producing an estimated 800,000 kWh of clean renewable energy annually. The solar power plant utilises Suntech’s high-efficiency polycrystalline photovoltaic modules with an IP68 waterproof rating.
