CSUN solar panels review

Average Customer Rating:

Tier 1

CSUN is Chinese solar panel manufacturer that is also known as China Sunergy. It produces tier one panels. Installers that we trust rate the quality of their panels highly. Their main line of panels has a 10 year product warranty and a 25 year performance warranty. They are corrosion resistant which makes them suitable for installation anywhere in Australia.

CSUN has suffered from financial troubles and has been ranked by one analyst as second from last in terms of financial strength of all the major Chinese solar panel manufacturers. 

The CSUN website states they have an office in Australia.  However, I have rung them multiple times on both numbers and get a message that they have been disconnected.  

There is an Australian company that imports CSUN panels and rebrands them as Matrix Australian Solar Panels. They provide a 12 year product and 30 year performance warranty. At the time of writing at the start of 2017 these panels are different from CSUN’s main line of panels and have lower efficiency.

CSUN Manufacturing Capacity

CSUN is a medium sized producer of solar panels and in 2016 claimed to have a production capacity of 1.3 gigawatts of solar panels per year and to have sold a total of over 3 gigawatts of panels. They also said they had sold over 4 gigawatts in total of solar products. By solar products, I assume they mean solar panels plus silicon wafers or solar cells sold to other companies.

In comparison, Jinko Solar, the world’s largest current producer of panels in 2016, produced an estimated 6.5 to 6.6 gigawatts of solar panels that year.

Company History

CSUN was founded in 2004 and started its first solar cell production line in 2005. They expanded rapidly and In 2007 they were listed on the NASDAQ stock exchange. By 2012 their module production capacity hit 1.2 gigawatts. This figure does not appear to have increased significantly since then, as the company has experienced major financial problems. As a result, they were delisted from the NASDAQ stock market for having a total share value of less than $15 million US.

Despite their financial difficulties, they were recognized by Bloomberg as being a tier one manufacturer in 2014.

Manufacturing Locations

CSUN produces most of its solar panels in Nanjing and Shanghai in China, but is unusual in having a much larger portion of its production in other countries than most Chinese panel manufacturers.

In 2013 they opened a panel assembly plant that uses imported solar cells in the Tuzla free trade zone in Istanbul, Turkey. Its capacity is apparently 300 megawatts, but so far has mostly operated at well below that. This factory’s location allows it to avoid Europe’s punitive import tariffs on Chinese made panels.

In 2014 they opened a 200 megawatt solar cell manufacturing plant in South Korea.

In 2015 they opened a panel manufacturing plant in Vietnam which sells panels under the sub-brand SolarieViet. These panels apparently have a 12 year product warranty and 25 year performance warranty. As this is their newest and presumably most up to date production facility, it may explain why feel confident enough to offer a 12 year product warranty rather than their standard 10 year product warranty, despite the fact that it’s not heavily automated.

CSUN Panels

Currently CSUN only has a single line of standard sized, 60 cell panels on their website, which are the type most likely to be installed on Australian roofs. These panels are from 280 to 290 watts and their efficiencies are moderately high, ranging from 17.2% to 17.9%.

They are corrosion resistant so they are suitable for installation in coastal areas.

CSUN’S Future

CSUN’s financial position was likely to have been the second worst of all major panel manufacturers in 2016. This puts the company at considerable risk of going under as a result of the fall in solar panel prices that is currently occurring currently.

This article on its first quarter financial report in 2015, and this one written a month later correctly advising investors to get out, give an indication of the problems the company experienced and is still suffering from.

But while the Chinese government is happy for smaller solar panel producers to disappear or be absorbed by more successful companies, they appear happy to allow larger companies that make it to tier one status to continue on life support for a long time. This is far from a guarantee that CSUN will survive, but does probably mean it has a chance of still being around in 10 years time.

My Recommendation

CSUN's panels are tier one, which means large financial institutions trust them for large scale solar farms.  Because CSUN has demonstrated they make durable panels, if my goal was to get low cost but reliable panels I would be fine with installing CSUN panels on my roof, provided the price was right.  This would be the case even if I suspected CSUN wouldn't be around in the future to honour their warranties, because the chance of my needing their warranty should be small.

Right in the middle of a heatwave at the moment and pretty much able to run my aircon and fans at no charge during the hot hours, and without the heatwave, dishwasher, drier fridge pretty much no cost during the daylight hours.

Panels have been working consistently all year with equal power generation from each one, observable online via the APS monitoring system 24/7. Self-cleaning in rainy conditions (had plenty of those!) and they generate power from dawn to dusk despite being flush-fitted to a NW facing colourbond roof with a 10 degree slope. Even on cloudy days they are still producing power, albeit in noticeably smaller amounts.

The panels preform very well. The only issue was just recently during heavy rain. Water had entered the DC isolation switch causing problems and fault in the system. The SolaX monitoring system was quick to sent me an email to tell me there was a fault. Contacted the repair agent and they where there that day to shut the system down to avoid any damage and che k an repaired the system in 3 days. They used a different type switch and repositioned it to keep it out of the weather. Apparently there quite a few system around town with the same issue with the DC isolation switch. System is all good and running normal.
