WINAICO solar panels in Australia

WINAICO Solar is a high-end solar PV panel manufacturer that puts an emphasis on the quality and reliability of its products. The WINAICO module range includes models for residential, commercial, and BIPV applications.

WINAICO Solar Panels: Top-shelf components and guaranteed yields

WINAICO says that it is set apart from other panel manufacturers in primarily two ways: The quality of the components used in its products, and the strict quality controls in assembly that ensure the end-product are manufactured and distributed to the highest standards.

The company prides itself in the selection of its partners. All components that make up a WINAICO solar panel are manufactured by industry leaders in their own fields, components are extensively tested and proven to last. Quality control and strict component selection process strongly contribute to WINAICO’s overall product and performance consistency.

WINAICO Solar is the solar brand of Taiwanese Win Win Precision Technology, which has its origins in the semiconductor industry, and the knowledge and experience to understand what is involved in manufacturing high-grade silicon products. The silicon photovoltaic (PV) cells within the modules themselves are highly pure and each is individually flash and electroluminesence tested for faults and weaknesses to guarantee high yield over the lifetime of the system 25+ years.

Blair PesterThe quality of components is monitored and managed at every stage of the production process – from incoming quality control through the complete production sequence to a 100% visual, micro-optical, mechanical, and electrical final inspection. With this rigorous oversight of all aspects of the production process, WINAICO is confident that it delivers a ‘perfectly assembled photovoltaic installation made with the best components available on the market.’

WINIACO’s quality control does not stop at the factory door. With a focus on end customers, the company established offices and warehouses in Australia over 5 years ago to ensure that their product gets to the end customer in perfect condition. WINAICO’s Managing Director Blair Pester personally selects its Authorised Installers carefully to ensure that every customer receives quality service, and prides himself in knowing every partner who has purchased a WINAICO Module.

Confident in its products’ performance, in October 2012 the company installed a test installation in the outback of Australia at the Desert Knowledge Facility near Alice Springs, customers can compare the performance of major panel brands against WINAICO to see how they fare.

WINAICO Solar: Points of difference

WINAICO uses only branded components of outstanding quality in its solar panels

WINAICO solar panels linear warranty

WINAICO solar panels linear warranty

-Linear performance warranty of 25 years. This means that having two or three ‘tiers’ of warranty as is the industry standard (90% of nameplate panel capacity guaranteed for the first 10 years, and 80% guaranteed for the next 15 years), WINAICO’s panels are guaranteed at about 94% for the first 5 years, 90% for the first 10, 87% for the first 15, etc. This more finely graduated warranty system means that system owners can have higher, more specific expectations about their panels’ performance than with many other installers.

15 year product guarantee. WINAICO panels are providing one of the longest product warranty available in the market. This is a result of their extensive testing over the past few years on their product.

Positive power tolerance of 0-5W: WINAICO panels are guaranteed to produce power at their nameplate capacity or greater

Innovative frame design for maximum stability

Module efficiencies now exceeding 19%

Each module undergoes infrared and micro-optical testing to ensure the highest level of quality

-WINAICO in Australia and Germany are also offering a unique system insurance which is designed to protect the homeowner of a system failure by external forces. This cover protects the end client against Loss of Yield, Interruption of Service and All Risks. This cover starts at 2 years (free of charge) can be extended to a total of 7 years and is unique to WINAICO.
