MANUFACTURED AND TESTED WITH PRECISION CIGS TECHNOLOGY FOR BEST PERFORMANCE AND DESIGN
Instead of using individual cells, the CIGS technology applies an ultra-thin photovoltaic layer to a substrate. This so-called “thin-film technology” utilizes an energy and material reduced production. The CIGS techno-logy, which uses copper indium gallium (di)selenide mixtures, stands for world best efficien-cies.
Q-Cells manufactures its CIGS solar mo-dules on highly automated production lines in “Solar Valley” in Bitterfeld-Wolfen, Germany. The CIGS layer is applied to a molybdenum-coated glass substrate. The thin-film cells are defined and connected in series by fine patterning lines on the glass substrate. In conjunction with a transpa-rent zinc oxide layer, the cells produce a photovoltaic effect when exposed to the sun. A comprehensive quality assurance pro-gram determines the production process, which is certified in accordance with ISO 9001. From the inspection of incoming goods through to performance measure-ment, each stage of the process is closely monitored, and every solar module can be traced back with respect to all the impor-tant production parameters.
100 % testing of the electrical and visual characteristics of the modules guarantees reliable quality and an outstanding appear-ance for both installers and system opera-tors. The use of the Q-Cells module testing center in “Solar Valley” has made it possible to es-tablish a comprehensive quality assurance system that exceeds the industry stan-dards. We are continuously optimizing our production processes and the quality of our modules which, in turn, enables us to achieve very low breakage and complaint rates.

Q.SMART solar modules achieve world record efficiencies of up to 13 %. No other thin-film modules in mass production currently offer higher energy yields. Furthermore, the new CIGS solar module Q.SMART UF L gene-rates a power output of up to 110 Wp due to a 25 % increased surface area. This also reduces system costs for installers and ope- rators.The high yields of all Q.SMART modules are a result of the outstanding behavior in low and oblique light, the favorable tem-perature coefficients and a cell geometry advantageous in the case of partial shad-ing. Q.SMART solar modules provide excel-lent output even on flat roofs or in locations that are unfavorably aligned.
Positive sorting of the power classes in +5 Wp increments further optimizes the output. Because of their optimal rain run-off characteristics, the unframed solar modules have the additional advantage of repeated self-cleaning and can thus achieve stable yields in the long term.

• Outstanding design with homogeneous black surface• Sophisticated aesthetics for rooftop and building integrated installations
where visual appearance is of crucial importance
14
The advantages of the attractive Q.SMART thin-film modules are persuasive. The frame- less models demonstrate their superiority in particular on slightly inclined roofs. The Q.SMART solar modules with frames are the preferred choice for steeper roofs, since they are adaptable and easy to handle. The increased reverse current resistance minimizes wiring efforts. High break resist-ance and precision design also facilitate installation.
SIMPLE, COST-EFFECTIVE INSTALLATIONTHE INTELLIGENT CHOICE FOR A WIDE RANGE OF APPLICATIONS
Q.SMART SOLAR MODULES WITH FRAMESThe framed Q.SMART modules have a black aluminum frame. Thanks to the hollow pro-file and strong corner joints, the frame is especially stable and flex-resistant. It has been certified for increased snow and wind loads up to 5400 Pa. Installation is quick and inexpensive since the 26 cm wide clamping area allows the modules to be in-stalled on roof hooks with just one layer of cross rails.
• Wide clamping range for cost-efficient mounting on roof hooks
• Approved for increased snow and wind loads of up to 5400 Pa
Q.SMART UF FRAMELESS SOLAR MODULES The frameless Q.SMART modules are per-manently protected from the elements by a stable glass encapsulation with proven edge sealing. With a front pane of 4 mm thick tempered safety glass (TSG), the la-minate thickness is just 7.3 mm. This stable construction minimizes the breakage rate of the glass-glass modules during transport, assembly, and operation.
• A wide range of installation options – from flat roofs to facades
• Minimal system costs due to optimum format of the Q.SMART UF L modules
15PRODUCT BENEFITS
• Minimal wiring effort due to a high reverse current resistance up to 6,5 A• 4 mm TSG front pane for increased breaking resistance
