WINAICO, Taiwan’s PV module manufacturer, will launch patented HeatCap technology at PV Taiwan 2014. HeatCap improves the reliability of silicon based solar cells, and protect them from micro-cracks induced by external stresses. The world’s first PERC-based high efficiency modules will also be displayed at WINAICO’s booth.

WINAICO’s high efficiency module with HeatCap technology was recently awarded the Taiwan Excellent PV Award by the Bureau of Energy. Also on display at WINAICO’s booth 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 the roof aesthetics.

WINAICO’s internal evaluation showed evidences of HeatCap improving the ultimate stress a silicon solar cell can withstand before breaking up to 18.12%. WINAICO also worked with 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 Taiwan’s solar industry,” said Davis Chen, Chairman and CEO of WINAICO. “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.”
