The pan weigh 132 pounds each (4.5 pounds per square foot). I have reviewed the architectural drawings for the residence and the p~ Swiss company that prefabricated the building components. I have not drawings for the building. The available information indicates that the and purlins supporting timber decking. drawings that were prepared by the n able to locate any actual structural structure consists of timber beams Based on the information at hand, it is my opinion that the roof structure ;is structurally capable of supporting the weight of the solar panels. Although I did not personally observe the' installation of the panels, if they were installed according to the instructions provided, it is also my opinion that the attachment of the mounting hardware to the roof structure is adequate.

Product Information Vitosol 100 Models s2.5, w2.5 The benefits at a glance: ■ High performance at an attractive price. ■ Optimized collection of solar energy thanks to highly efficient Sol-titanium coating. ■ Collector surface area: 27 ft2/2.5 m2 for horizontal or vertical installation. ■ High efficiency through selectively coated absorber, integrated piping and extremely effective thermal insulation. ■ Flexible connection pipes facilitate short installation times. Up to ten collectors can be quickly installed in series using a convenient plug-in system. ■ Durable, corrosion resistant construction using materials such as powder coated aluminum, copper and stainless steel, as well as 4 mm special low-iron solar glass and non-degrading thermal insulation. ■ Universal application: on flat and sloped roofs, on top of roof coverings, or for freestanding installations. ■ Quality tested at SPF Institut, Rapperswil, Switzerland. Meets the requirements of the German "Blue Angel" certificate of environmental excellence. Construction and function The main component of the Vitosol 100 is the Sol-titanium coated copper absorber. It ensures high absorption of solar radiation and low emission of thermal radiation. A meander-shaped copper pipe, through which the heat transfer medium flows, is permanently embedded into the absorber. The heat transfer medium channels the absorber heat through the copper pipe. The absorber is encased in a highly insulated collector housing, which minimizes collector heat losses. The high quality thermal insulation provides temperature stability and is free from gas emissions. The cover consists of a solar glass panel with a very low iron content, thereby reducing reflection losses. The solar glass is 4 mm thick, making it very resistant to weather influences. The glass is set into the collector frame with a continuous profiled seal, preventing water from penetrating into the collector. This ensures a long and reliable service life for all internal components. The collector housing consists of a powder-coated aluminum frame (recycled aluminum), into which the solar glass is permanently sealed. Up to ten collectors can be joined quickly and easily to form a single collector array. For this, the standard equipment includes flexible connection pipes, sealed with O-rings (see picture below). A connection kit with clamping ring fittings enables the collector array to be quickly connected to the pipes of the solar circuit. The collector temperature sensor is installed in the solar circuit flow using a sensor well set. n O /'IN N N un 00 N m n A Continuous profiled seal (vulcanized) E Melamine resin foam B Solar glass cover, 0.16"/4 mm thick F Mineral fiber insulation C Meander-shaped copper pipe G Aluminum frame sections D Copper absorber H Aluminum-zinc base panel Technical Data Technical Data s2.5 w2.5 / Model ft2 / m2 29.2 / 2.71 29.2 / 2.71 Total surface area 2 / m2 f 27.0 / 2.50 27.0/2.50 Absorber surface area t. ft.2 m2 / 27.Q / 2.50 27.0/ 2.50 Aperture 94 Dimensions "t inches 45 ♦2385 Width mm 1138 45 Height inches 1 2385 1138 4 mm 4 Depth inches 102 102 mm 84 84 Optical efficiency % 3.36 3.36 Heat loss coefficient Ut W/(m2 K) W/1m2.

IMPORTANT The roof bracket must be securely attached to the roof joist of the structure. Only use stainless steel attachment screws. IMPORTANT The 1.2" / 30 mm screws provided with the mounting kit are insufficient length for most wood frame roofs and should not be used for mounting the roof brackets. The installer must provide stainless steel 3" / 80 mm (preferrably 4" / 100 mm) lag bolts or screws. ~I o LO N L 6 Attaching roof brackets on shingled roof TN Installation dimensions for ten s2.5 collector panels Installation on Sloped Roofs 6.
