1 YES TO PHOTOVOLTAICS! 8 steps to WINAICO!

2 1. YES TO TOP PERFORMANCE CONFIRMED BY INDEPENDENT INSTITUTES. Whether it s about performance or reliability under actual conditions in practice the ratings and tests by industry experts and independent institutes always show WINAICO modules in the top rankings. The reason for this is that as a leading manufacturer of high-performance photovoltaic modules from Taiwan and a global photovoltaic specialist WINAICO places great importance on 100% quality control in the entire process chain from material procurement to production to operation and maintenance by our specialist partners + In 2014, in the PTC ratings of 260 W poly modules, WINAICO achieved first place among more than 14,000 modules ahead of leading brands and suppliers from around the world. The PTC rating (Photovoltaic Utility Scale Application Testing Conditions) was initiated by the California Energy Commission and evaluates real performance in practice. A higher rating means you get more electricity produced per installed watt and thus a faster return on investment. + WINAICO s modules have proven their superiority even in extremely hot and dry conditions with strong variations in day and night temperatures in Australia. In the Desert Knowledge Australia Solar Centre WINAICO crystalline silicone modules achieved a higher normalised daily output than the products of other prominent brands and international market leaders. In the pilot plants at the Desert Knowledge Australia Solar Centre the real output of various modules is tested. + Taiwan s Bureau of Energy has awarded WINAICO s WSP-M6 PERC module the Taiwan Excellent PV Award as the best PV module in terms of safety, reliability and efficiency. The award was for reliability tests, which Taiwan s leading test institute ITRI carried out based on NREL s Qualification Plus and the new IEC initiative all which confirm WINAICO s promised performance. 2

It provides live system level data of onsite installations in the Australian terrain, and is a reference point for installations operating in extremely hot and dry conditions. 4,80 4,60 WINAICO Tier 1 Japanese brand Tier 1 Norwegian brand Tier 1 German brand Tier 1 US brand Tier 1 Chinese brand Since WINAICO modules were installed in 2012, our modules have shown the least power degradation over the years. WINAICO modules have proven to be the most reliable even when installed in the desert. 3

4 2. YES TO INVESTMENT PROTECTION THROUGH SUPERIOR QUALITY WAY ABOVE STANDARD! Norms and standards are there to be exceeded. WINAICO modules go through all the relevant tests and significantly exceed the market requirements in all areas. The complete set of reliability tests are designed to imitate all variations of hazards experienced by the modules during their useful lifetime. As a result of WINAICO s evaluation, the modules can withstand wind, weather and other adversities much better and much longer. + The thermal shock test measures how the modules withstand thermal stresses due to changes in temperature. As such, they are cooled down from +85 C to 40 C and then reheated to +85 C. + Dynamic mechanical load refers to a change in pressure, due to strong winds and squalls, for example, in which WINAICO modules have to withstand 4,000 Pa for 1,000 cycles, a test that is not required by the IEC. + The damp heat test checks how the modules are capable of withstanding humidity and heat (85 C at 85 % relative humidity) over a prolonged period. + Due to potential-induced degradation (PID) yield losses of 20 % and more may occur in conventional photovoltaic systems. Long-term tests show that this effect could be reduced to a minimum in WINAICO s modules kg/m 2 + The mechanical load refers to the pressure a module can endure due to snow, for example. While the IEC standard requires only 5,400 Pa, WINAICO modules can always bear a load of up to 10,000 Pa, which is equivalent to about 1,020 kg per square metre. + High concentrations of salt in the air are aggressive environmental factors that may have an influence on the output of PV modules. Certification to IEC guarantees consistently high-energy yields even for sites with high concentrations of salt and ammonia gas. + In the hail test WINAICO modules have to deal with four times the kinetic energy prescribed by the IEC standard and withstand it easily. Even if it is hailing golf balls, this is no problem for WINAICO modules. + Ammonia emissions from livestock may also accelerate the ageing of PV modules, which results in falling energy yields and therefore a lower return for the system operator. WINAICO modules are tested for resistance to ammonia to alleviate this risk. 4

6 3. YES TO TWO YEARS OF FREE INSURANCE COVERAGE WITH AN OPTION FOR EIGHT MORE YEARS. * A four-in-one insurance package provides additional security. When you purchase WINAICO modules, two years of free insurance coverage is already included in the complete photovoltaic system. This secures your investment from all material damage, e.g. due to fire, natural disasters such as storms and hail, theft, operational errors or rodent damage and it starts at the construction stage. In addition, the loss of Feed-in Tariff income due to system downtimes are also compensated. The insurance ends automatically after two years or may be extended after this by a further eight years, which means insurance coverage applies for a total of 10 years. + All risks insurance: protection from damage Covers all unforeseen damage or destruction incurred. + Business interruption insurance: protection from loss of profits Compensates for loss of feed-in tariff if the technical use of the photovoltaic system is interrupted or adversely affected by damage or non-delivery. + Reduced yield insurance: protection from long-term low yields Covers the lower income earned if the annual yield is more than 10% lower than forecast. + Construction cover: protection at the construction stage All potential damage is already covered by the insurance during the construction stage: no matter whether there is a threat of theft, fire or storms on the construction site. + And easy administration Quick and straightforward registration the contract automatically ends after the period of validity.

8 4. YES TO THE HIGHEST QUALITY COMPONENTS FOR LONG-TERM HIGH-PERFORMANCE MODULES. Throughout the course of their service lives, photovoltaic modules are exposed to more than 25 years of severe environmental influences. Be it hail, snow or heat: Photovoltaic modules must deliver sustained peak performance. The use of high quality components therefore plays a decisive role. WINAICO has consistently used high class, weather-resistant components from market leaders exclusively the best from the best. The EVA film: the reliable contact area. EVA films connect the solar cells to the glass surface and encapsulate the module. If they are of poor quality, they may come loose and turn yellow. The quality film used by WINAICO guarantees the insulation and protective effect for the entire lifetime of the module. It increases the module s output by 3 % and ensures consistent energy production. Glass: the best door opener. WINAICO uses exclusively highly transmissive front glass this has a direct positive effect on the module s performance and yield. The additional anti-reflective coating on the glass reduces the amount of reflected light and increases the amount of light absorbed by the solar cells by 2.5%. It contributes to the module s superior efficiency and mechanical stability. The glass also protects the components inside from the weather and other external influences EVA-film Standard module ( ) EVA-film WINAICO High- Efficiencymodules ( ) IR visible UV Glass absorption Output Reflected light ARC coating 1500 The adhesive tape: the flexible seal. The adhesive tape connects the aluminium frame and the glass. Unlike a silicone seal the adhesive tape has very high resistance to heat, UV light and chemical attacks, such as by ammonia. The adhesive tape used by WINAICO provides an excellent seal against dirt and moisture, is particularly resilient and compensates for the different expansions of glass and aluminium without causing stress. The result is a reliable and long-lasting adhesive. WINAICO high efficiency module Standard module Time of day

10 5. YES TO LEADING TECHNOLOGY FOR ADVANCED PRODUCTS. With WINAICO modules, you purchase products from a manufacturer who specialises in premium quality solar modules. Comprehensive experience and expertise from the semiconductor sector, coupled with ultramodern production technology, enables high process mastery and outstanding quality. As such, with HeatCap WINAICO has once again further developed its technology and set new standards. PERC technology. PERC stands for Passivated Emitter and Rear Cell and the resulting improvements in temperature and low light behaviour increases efficiency by up to 1 %. PERC solar cell Standard solar cell The HeatCap -Technology. Mechanical and thermal loads are the main causes of micro-cracks. The extent of any microcracks is rarely discernible on-site at the installation. However, drops in performance caused by micro-cracks are detectable across the entire service life of the PV plant. Internal tests by WINAICO have shown that HeatCap increases the mechanical load-bearing capability of a monocrystalline silicon solar cell by up to %, and that of polycrystalline silicon solar cells by up to %. 250 Silicon Power reflector Aluminium back contact Silicon Aluminium back contact Contact strips: the clever transport network. WINAICO chooses highly reflective, light-detecting contact strips, so the rays of light falling on the strips are absorbed by the solar cells with total internal reflection. The result is a light absorption increase of 2.5% and therefore enhanced module efficiency. The more contact strips that are placed in the cell (e.g. 3 or 4-bus bar), the more electricity can be fed into the electrical system without loss.
