GCL-Poly Suzhou Energy solar panels review

UPDATE: 18 December, 2018 - The Clean Energy Council has announced that all GCL System Integration PV modules will be de-listed from its Approved Products List on 19 December, 2018 due to the presence of components detected in testing that were outside the scope of the modules' certificate. A listing is required at the time of installation in order for a system to be eligible for Australia's major solar subsidy.

GCL

While GCL has been producing silicon for solar cells for over 20 years, they are a relative newcomer to solar panel manufacturing. They are recognized as a tier one manufacturer.

GCL produces panels with an industry standard 10 year product warranty and either a 25 or 30 year performance warranty. They don’t have an Australian office at the moment, but they do have an Australian partner, One Stop Warehouse.

The Massive GCL Corporation

GCL, or to give it its full name, Golden Concord Holdings Limited, is a massive Chinese corporation with around $21 billion worth of assets worldwide. With worldwide meaning mostly in China.

In addition to producing silicon for solar panels, they are also involved in oil and natural gas exploration, and Liquid Natural Gas transportation.

The corporation established the GCL-Poly company in 1996 and it now produces around 35% of the world’s supply of silicon wafers used to make solar cells. In 2016 they will produce a total of over 16 gigawatts worth. That could make more than two and a half times the total solar capacity of Australia at the end of 2016.

GCL has not been content to merely supply silicon to other companies so they can use it to make solar panels. They have also recently moved strongly, decisively, and with verve, into solar panel manufacture. Their expansion into panel manufacture has occurred at phenomenal speed and in the first half of 2016 they became the 6th largest panel manufacturer in the world.

GCL’s Solar Panel Division is GCL System Integration Technology Co.

In order to facilitate developing solar panel manufacturing capacity, and possibly to make it easier to cover up their mistake if it doesn’t work out, GCL created GCL System Integration Technology Co.

GCL Panel Efficiency

GCL solar panels can be up to 17.5% efficient.

Corrosion Resistance

GCL’s 60 cell panels are the ones most likely to be installed on Australian roofs and their datasheets all state they are certified as corrosion resistant. This makes them suitable for installation near the sea.

The GCL Battery

GCL makes a home battery storage system. As it is a very different technology from solar panels, it is probably not possible to draw any strong conclusions about the quality of their panels from the quality of their battery, or vice-versa.

Australian Partner

GCL does not appear to have an Australian office, but they do have an Australian Partner, One Stop Warehouse. Their head office is in Woodridge, which is about half an hour’s drive from central Brisbane. As the importer of GCL panels, they would be considered the manufacturer under Australian Consumer Law. Therefore, the continued existence of their warranty will depend upon One Stop Warehouse continuing to exist and not GCL.

My Recommendation

When GCL solar panels first appeared, I heard one or two anecdotal stories about problems with them, but since mid 2017, I've started to hear very positive reports from installers about their performance and improved quality. However, the recent news of all GCL's panels being de-listed by the CEC means there are obviously issues the company needs to sort out.
