About Winaico, Solar Panels

Winaico solar panels review

Founded in 2008, Winaico is a Taiwanese solar panel manufacturer that produces modules boasting a 25 year product and performance warranty in Australia.

The company has had a physical local presence here since 2012 - a very handy thing for tech support and warranty issues. Winaico's Australian office is in Sydney. 

Manufacturing Capacity

Winaico has previously advised their manufacturing capacity is 200 MW annually, but that was a couple of years ago. Current production capacity doesn't appear to be noted on the global Winaico web site.

Manufacturing Locations

Winaico manufactures solar panels in the city of Hsinchu in north-west Taiwan and also in its Chinese facilities.

While the company has manufacturing capacity in Taiwan, it seems most of the panels for the Australian market are either being produced in China or the components used in Taiwanese production come from China.

It's certainly not uncommon for panel manufacturers outside of China to use components from that country; it's just that Winaico chooses to acknowledge this. 

Winaico Performs Well At Desert Knowledge Australia Solar Centre

The Desert Knowledge Australia Solar Centre, or DKASC to its friends, has installed a range of solar panels from different manufacturers so their performance under harsh central Australian conditions can be tested.

Winaico has previous stated of all the panels, theirs have deteriorated the least. And if you go to the DKASC web site and compare the Winaico solar panels to other panels installed in a fixed position at around the same time (2012), this certainly appears to be true.

Winaico Also Performs Wonderfully With Taiwanese VPC Tests

Voluntary Production Certification (VPC) tests are strenuous and designed to demonstrate that a panel can perform well in simulated harsh environments. The tests include damp heat, PID, thermal cycling, salt mist, and performance attenuation. Winaico put out a press release about their performance in VPC testing back in 2019 here.

Winaico’s Solar Panel Specs And Product Warranties

The most powerful Winaico monofacial panels currently available in Australia for residential purposes are the WST-MGX-P3; available in capacities up to 415W. 

The WST-MGX-P3 Gemini combines half cell, multi-busbar and reflective wire designs to maximise efficiency and reduce internal resistance. 

You can find more specifications and approximate retail pricing for the WST-MGX-P3 Gemini and other Winaico modules on SQ's solar panel comparison table.

Corrosion Resistance

All Winaico solar panels are IEC 61701 certified, level 6, and are suited to installation in areas close to the sea. You can see the full certification here.

Temperature Coefficient

Winaico's current stable of product offerings have a temperature coefficient of -0.35%/°C. This figure is how much their efficiency drops by for each degree increase in module temperature over 25 degrees, and is comparable to most other good quality panels available today.

LeTID Certification

Winaico has certified all of its panels to be LeTID resistant. You can read all about what LeTID is here. Suffice it to say - it's something you want to avoid. The full certification document is here.

Warranty Claim Procedure For Orphaned Customers

If you have an issue with your Winaico panels and your original installer has gone out of business, Winaico become responsible for handling warranty claims. Their contact number is 02 8091 2771 - and they have advised they have a network of installers that can handle the process from start to finish. Labor costs are covered under warranty - $120 for the first panel, and $60 for each panel afterwards.

My Recommendation

Winaico produces quality panels and I would have no problem installing them on my roof. Their performance at the Desert Knowledge Australia Solar Centre, as well as with Taiwanese VPC testing, suggests they will do well under Australian conditions over the long term and their 25 year product warranty is impressive.

The panels look good, have a high wattage output and from visual inspection and feeling/touching the panels appear to be made very well.

They immediately started outperforming expectations and have not stopped. I am very impressed by how late in the day they continue to produce (29 x N-Type Bifacial WST-425NGXB-D3 full black on North, East, & West). They also look really slick!

Their design means they do not look out of place on the roof of the house (aesthetically pleasing).

Installed for a bit over 5 months, its still early days.
60 x Winaico wst-400mgx-p3 gemini, Black version 400W each for a total of 24KW.
These are installed in a Hybrid system on a Tiled Federation style house with a rectangular roof.
20KW facing North and 4KW facing EAST plus another 4KW facing North.
Maximum peak has been at 21+KW due to a very restrictive export limitation of only 2.3KW. The batteries are close to fully charged well before we have reached PEAK Zenit and as such, demand + export, even with the EV charging at 7KW is well below of what they are capable of.
So far the panels are performing to and even above expectation. This is coming from a User that has been using solar for about 20 years now.
The black panels look very unobtrusive and suit the roof really well.
If you are looking at a higher quality solar installation and are willing to pay a little bit more....then these panels should go on your short list.

The panels look great and start functioning with very low light. I have been very impressed with their sensitivity to light even when there is no direct sunlight on them. The panels are producing well and I’m very happy with the winter performance.
(The system is just over 12KW but that option was not available in selecting the system size above)

They look nice, but owing to delays in the meter changeover the system has not been active yet. The meter changeover has been long done and it has been reliably producing power ever since.

My wife loves these panels - they look great. As we are on the coast, David from NRG suggested to spend a bit more on panels that are more resistant to salt damage.
