WINAICO has launched a new high-performance 310W 60-cell (PERC) PV module that is designed to withstand typhoon-level winds and the long-term damage caused by high and sustained vibrations that can cause micro-cracks in the solar cells. 

Problem

Located at the western edge of the Pacific Ocean, Taiwan and Japan are the most typhoon-prone countries in the world, affected by more than 30% of the world’s tropical typhoons each year. The recent Soudelor typhoon that hit Taiwan in August, 2015 devastated solar systems throughout the island, causing as much as NT$30 million (US$9.2 million) of damage to a single solar installation in southern Taiwan, according to the company. When solar installations are affected by strong winds, the modules are subjected to constant vibrations with sudden impulses of forces acting from both front and rear sides, in an alternating fashion.

Solution

WINAICO has combined two technologies uniquely available to the module producer, including the micro-crack preventing HeatCap technology, and structurally reinforced WSP frame, to create a line of typhoon-resistant solar modules specifically for typhoon-prone markets such as Taiwan and Japan.

Applications

Residential, commercial and utility-scale projects in typhoon-prone regions such as Japan and Taiwan.

Platform

WINAICO has worked with Taiwan’s leading research institute, ITRI, to perform Dynamic Mechanical Load (DML) tests to simulate the effects of strong wind on WINAICO’s HeatCap modules. HeatCap modules have been tested to endure 1000 cycles of 4000 Pa DML tests with no more than 0.18% of power degradation, while the comparison case without HeatCap degraded by 2.32%. The DML criteria of 4000 Pa is comparable to 202 km/h, level 17 intensity wind on the Beaufort scale, similar to a Category 4 typhoon. WINAICO’s own WSP frame is designed with strength and reliability by utilising an external L-key construction. Unlike the common inner L-key design, the WSP frame has no single point of weakness, and has been tested to withstand more than 7200 Pa of static Mechanical Load (ML), far exceeding the 5400 Pa requirement described in IEC 61215.

Availability

October, 2015 onwards.

The WCPEC is the world’s biggest platform for PV research and development, offering a unique possibility of international exchange by combining the three largest and most prominent international PV conferences: the European PV Solar Energy Conference (EU PVSEC), the Photovoltaic Specialists Conference (IEEE PVSC) and the International PV Science and Engineering Conference (PVSEC). In 2022, Europe has the honour to host the 8th World Conference on Photovoltaic Energy Conversion, interchanging the prestigious EU PVSEC for this year, that is being held annually for more than 40 years. After being in place for more than a quarter of a century, the WCPEC, being held every four years, is firmly established among the global PV community as THE event for the greatest minds and experts in various PV sectors to meet and discuss, to exchange and network! The conference programme is coordinated by the European Commission Joint Research Centre.

The demand for rooftop solar PV is soaring, driven by falling costs of the technology against energy crises that are gripping countries globally. But while an increasing number of households turn to solar to generate their own electricity, there is now a need for more specialist equipment, technologies and services to ensure the solar transition can reach as many customers as possible. Delivering these is now a major challenge for rooftop solar installers. This webinar will analyse the characteristics of the rooftop solar market, discussing how the products, logistics, installation and servicing of solar systems has evolved in line with consumer demands.
