Winaico solar panels reviews

Winaico

Winaico is a Taiwanese manufacturer of tier one panels with 15 year product warranties.  This is well above the industry standard to 10 to 12 years.  They also carry 25 year performance warranties. 

Winaico has an Australian office in Sydney.

Manufacturing Capacity

Winaico has advised that their current manufacturing capacity is 200 MW annually. 

Manufacturing Location

Winaico manufactures solar panels in the city of Hsinchu, in north-west Taiwan. Its population is 430,000 and it is known as the windy city. Possibly on account of how typhoons like to smash into it. This probably has something to do with why Winaico designed a typhoon resistant panel.

Winaico Performs Wonderfully 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. Winaco says of all the panels, theirs have deteriorated the least. And if you go to their site and compare the Winaico panels to other panels installed in a fixed position at around the same time, this certainly appears to be true.

Winaico Also Performs Wonderfully With Taiwanese Voluntary Production Ceritification (VPC) Tests

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 has put out a press release about their performance in VPC testing here.

Winaico’s Panels Have 15 Year Product Warranties

Winaico’s other series of panels have 15 year product warranties that is well above the industry standard and 25 year performance warranties.  They range from 285 to 330 watts. They can be up to 19.4% efficient. All of them are standard sized 60 cell panels

Corrosion Resistance

All Winaico 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 temperature coefficients ranging from -0.41%/°C to -0.38%/°C. This figures is how much their efficiency drops by for each degree increase in temperature over 25 degrees, and is comparable to most other 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 that 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 tier one 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 and their 15 year product warranty is impressive.
