2 2 Crystalline solar modules Our crystalline solar modules High-performance with stable yields Bosch Solar Energy offers photovoltaic modules consisting of highly efficient monocrystalline silicon solar cells in 156 mm x 156 mm format manufactured in its own integrated production process. These solar modules impress thanks to their high efficiency and stable yields. There are two performance classes with 48 or 60 cells per module with the performance classes dependent on the number of cells in the module. Bosch Solar Modules c-si M 48, c-si M 60, c-si M 60 S 1 Flexibility meets power For small areas and greater adaptability Bosch Solar Modules c-si M 48 2 Sun meets power For locations where performance counts Bosch Solar Modules c-si M 60 Versatile usage on smaller areas or on special roof sizes to ensure best possible utilization 2 3 Ideally suited for all locations where long-term, stable yields and optimum area usage are of major importance Consistent energy generation with the c-si M 60 in coastal areas and agricultural environments 1 3 Style meets power Bosch Solar Modules c-si M 60 S Jet black frame and module components for aesthetically appealing on-roof systems The stylish appearance of modules blends elegantly into the roof and surrounding architecture

3 Crystalline solar modules 3 Which module is the right one for my home? The type of module suited to your needs depends on the installation location and the available size of your roof on your home. Photovoltaic modules made with monocrystalline solar cells excel thanks to their high efficiency and are therefore particularly suitable for small, optimally positioned rooftops. Monocrystalline solar modules feature a black surface, which, together with their ultra-slim structure, add aesthetic appeal. The only difference between monocrystalline modules with 48 cells or those with 60 cells is their size. The decision on whether to use the smaller or larger module depends on the available installation area. The Bosch Solar Energy product portfolio also contains polycrystalline solar modules and thin film modules. Polycrystalline solar modules have a lower efficiency than their monocrystalline counterparts. You can identify them easily thanks to the blue shimmering, crystal-like surface of their cells. Thin film modules are primarily used in large area installations.

4 4 Crystalline solar modules Our products Everything from a single source New production processes and the next product generations are developed at the Center of Expertise and main plant for crystalline photovoltaics in Arnstadt, Germany. The production facilities in Arnstadt cover the entire value added chain, from crystal pulling (drawing ingots) and wafer production through to solar cell and module manufacture. The Center of Expertise consists of an ultramodern research and development center, a vocational training center, and the company headquarters. An integrated production process enables Bosch Solar Energy to guarantee compliance with high quality standards at all stages in the value added chain. Quality starts with the purchase of raw materials and leads to stable products, which are crucial for maximizing returns on your investment.

5 Crystalline solar modules 5 Quality Documented and certified "It has always been an unbearable thought to me that someone could inspect one of my products and prove that I supply an inferior product in some way. That s why I have always tried to only deliver products which withstand the closest scrutiny products which prove themselves superior in every respect." Robert Bosch, Robert Bosch Solar modules are an sustainable investment. For this reason, we pay close attention to the performance of our products during their long-term use. Comprehensive checks and tests assure you and us both that Bosch solar modules deliver what we promise. We monitor the long-term performance of modules when exposed to high and low temperatures, high humidity and salty air, which also enables us to guarantee installations in coastal areas. Mechanical load and suction load tests which go beyond the requirements specified in industrial standards allow us to ensure that Bosch solar modules are able to withstand all weather conditions. We also pay attention to the smallest details while production is in progress. For example, electroluminescence tests are performed on each module to ensure that Bosch's high quality standard is maintained for each module. Selected installations are studied and evaluated on a regular basis and the knowledge gained is taken into account when developing new generations of solar modules. Weather resistance is an important factor

6 6 Crystalline solar modules Warranties for you and your future Thanks to our meticulous development process, an ultramodern production system and extensive testing, we are able to offer end customers the following warranties for Bosch solar modules in addition to the contractual warranty provided by the respective vendor. Product warranty*: Bosch Solar Energy guarantees that purchased modules are free of material and processing defects. Warranty period: 10 years for crystalline modules. Performance warranty*: Bosch Solar Energy guarantees that modules achieve the minimum output specified on their data sheet. Warranty period: in the case of crystalline modules, we guarantee 90 % of the specified minimum output on the data sheet for 10 years and 80 % for 25 years. Warranty claim*: In the event of a warranty claim, Bosch Solar Energy AG will, at its own discretion, replace the module with a new module of the same type, eliminate the defects, or refund the lost revenue of the relevant module. *This is only a basic outline of our warranty coverage. You can find the full warranty conditions for photovoltaic modules at or request them from your installer.

7 Crystalline solar modules 7 Quality certificates We test two and half times longer than the period specified by DIN (German Institute for Standardization) to make even more accurate statements on longevity and the associated high quality of our modules. Product certificates and awards Bosch Solar Energy solar modules are able to withstand all weather conditions, even in coastal areas. TÜV Rheinland has tested our modules and confirmed that they can support a mechanical load of over 5,400 pascals, or about 550 kilograms per square meter, which corresponds to about 880 kilograms of weight acting across the surface of a crystalline module with 60 cells. No matter whether they are exposed to snow, hail, rain, or wind, our modules are able to withstand most conditions. The mechanical and wind suction load test as per IEC 61215, Edition 2, certifies the suitability of our crystalline solar modules to withstand wind, snow, ice and structural loads up to 5,400 Pa. The salt spray test as per IEC certifies that tested crystalline solar modules provide resistance to corrosion caused by salt spray, a problem which may arise in coastal areas. The ammonia test as per IEC certifies resistance of our crystalline solar modules to high exposure to ammonia, a condition found in places such as agricultural buildings. Bosch solar modules conform to the strictest standards. The crystalline modules c-si M 60 EU and c-si M 60 S EU were honored with a prestigious Plus X Award in 2011, when they impressed in the High Quality, Design, and Ecology categories. Company s certificates Quality management: from silicon and high-performance solar cells to longlasting solar modules, Bosch Solar Energy s high quality standard for its production process has been tested and certified according to DIN EN ISO 9001:2008.
