Collector USP’s DescriptionCompetitor's SpecificationBOSCH SpecificationAdvantage Collector Construction Collector housing is fabricated by using screws and rivets at each corners of profile Screw less construction. Not a single screw or rivet is used for construction. More Robust Design Back Plate fixing Back plate of the collector is fixed to the frame assembly by using screws and rivets. Back plate is fixed by using double ended adhesive and also with back plate clip. No holes or screws or rivets More robust Design Absorber theft Absorber can be easily removed from the collector at site just by unscrewing few screws Requires special tools to remove the glass clip, not easy for thieves to remove the glass and steal the absorber. Theft Proof Design Installation Collector has to be mounted on the mounting structure by drilling holes in the collector frame Collector mounted on the structure with profile clamps Easy to assembly, No need to drill holes in the collector frame BOSCH THERMOTECHNOLOGY

Collector USP’s DescriptionCompetitor's SpecificationBOSCH SpecificationAdvantage Unique Design The Aluminum profiles used by all competitors are very similar. It is easy for anybody to duplicate the product With the Unique design of collector, it is virtually not possible for small competitors to duplicate the product Duplication of Collector design very difficult. Better Aesthetics compared to any competitors Corner Caps Not available with any competitors Plastic End caps provided at all four corners of the collector End caps provides protection against damage during transit and installation. It also adds aesthetics to the product BOSCH THERMOTECHNOLOGY Firsts in Indian Market by BOSCH Full sheet absorber instead of fins to provide better heat absorption German screw less design for better output and safety of absorber sheet Snap fit technology for mounting structures for faster and better installations

BOSCH THERMOTECHNOLOGY Domestic Tests for collector stability  Wind / Snow Load on collector glass side Determination of Static load equivalent for the wind/snow load The collector was loaded with 865 kg from the glass side to simulate the loading condition Inspected for physical damages  Wind Load on collector rear plate Determination of Static load equivalent for the wind/snow load The collector was loaded with 312kg from the rear plate side to simulate the loading condition Inspected for physical damages The collector was allowed to fall freely on the rear side to check the stability of the collector assembly Inspected collector for physical damages  Impact Test on Glass Steel ball of 150g was allowed to fall from a height of 1m at all corners of the collector. Inspected collector glass for physical damages  Free Fall Test  Pressure Test at High Temperature The collector was pressurized to 5 bar at stagnation temperature Performance and leakage inspection
