WINAICO launches patented micro-crack preventing HeatCap technology

Share

WINAICO, Taiwan's largest PV module manufacturer, launched its patented HeatCap technology at PV Taiwan 2014.

HeatCap improves the reliability of silicon-based solar cells and protects them from micro-cracks induced by external stresses, such as handling errors and wind stresses.

WINAICO's high-efficiency module with HeatCap technology was recently awarded the Taiwan Excellent PV Award by the Taiwan Bureau of Energy.

Also on display at WINAICO’s booth at the conference, which ends today (Friday) are the world's first PERC-based 300 W WSP-300M6 (60-cell) and 230 W WST-230M6 (48-cell) high-efficiency modules.

WINAICO's 280 W, WSP-280M6 all-black module demonstrates the perfect combination of high energy output and beautiful design, suitable for any residential application without compromising roof aesthetics.

The manufacturer's internal evaluation showed evidence of HeatCap improving the ultimate stress a silicon solar cell can withstand before breaking up to 18.12%.

WINAICO also worked with Taiwan's leading research institute, the ITRI, to evaluate the reliability of HeatCap technology through Dynamic Mechanical Load (DML) and local hot spot tests.

HeatCap and reference modules were put through DML tests of 1000 cycles each at 1000 Pa, 2000 Pa, 3000 Pa, sequentially, and verified by electroluminescence (EL) pictures.

Compared to the reference module, the HeatCap module had significantly less micro-cracks after each stage of DML tests.

Local hot spot tests provided evidence of HeatCap's improvement in heat dissipation to reduce the solar cell temperature, compared to reference cells.

HeatCap can be used to solve the heating issue common to modules with black back sheets, and improve energy outputs of all-black modules in warmer environments.

"PV Taiwan is an opportunity to show the world the health and innovation of the Taiwanese solar industry," said Davis Chen, chairman and CEO of WINAICO. "With the launch of the micro-crack preventing HeatCap technology, WINAICO continues to be a technology leader and differentiates our product offering with greater reliability to the end customer.

"The 300 W and 230 W modules on display reinforce WINAICO's position as a producer of PV modules with the best power density, and the leader in residential solar solutions."
