It consists of a number of layers to protect the circuit of solar PV cells and to make the module easy to install. The materials used in these layers determine the cost and durability of the modules.Slide 2: The solar cells themselves and their circuits are totally wrapped in plastic. A shock resistant, shatter proof glass covers the solar PV cells and provides a clear, low absorption cover for the solar panel. It is also tempered for strength in order to reduce the effects of falling trees or hail.Slide 3: The multi-layered back sheet protects the plastic and cells from abrasions and prevents moisture from getting into the module. An edge seal is applied to protect the edges of the glass from the infiltration of dirt, water, or other non-friendly substances. The metal frame is secured around the entire glass laminate.Slide 4: The all metal frame provides the structure and strength. It is the frame that is then bolted to the mounting system embedded directly into the roofing structure. Common Solar Module Design Types There are three basic module solar designs. The first is the standard frame module that you may have experienced in the past.Slide 5: This design approach has been used for 30 years and usually involves an aluminum frame that allows the modules to be mounted onto a rail structure of some kind that is then directly attached to the roof. The modules are positioned above the roof surface, providing space for air to flow under the module, which helps cool the system and makes it work more efficiently.Slide 6: At the same time, rain water, leaves, twigs, and other debris can also flow under the solar panels. The rail structure is attached to the roof by means of posts that are secured into the roof rafters with long lag screws. Roof mounted systems is a good fit for structures comprised of ceramic tiles and wood & asphalt shingles.Slide 7: Modified Metal Frame for a Ground Mount Module Design This module design can also be mounted to a ground based frame structure. Such a structure can be built on any stable terrain, can be made of metal or wood, and can hold the modules at any tilt angle or azimuth orientation (note: see previous articles related to sun angles).Slide 8: The ground mount can also be a pole structure to cut down on foundation work to your home. It can be stationary (i.e. not have a small motor to constantly orientate the solar panel with the sun as it tracks across the sky) or it can use a small motor to track the sun throughout the day and year.Slide 9: Residential Roof Integrated Solar Energy Modules A second type of module design is one that allows the module to be integrated into residential roofing materials. Systems connecting directly to the roofing materials (i.e. replacing shingles or laying flat to the roofing boards) are called integrated solar modules. The module frame design is modified so that it has the same profile as neighboring flat concrete tiles.Slide 10: Types Integrated Solar PV Panels One is the mono crystalline ridged frame design offered by some existing manufacturers. The integrated solar cells have better through put and are gaining in efficiency all of the time. They also incorporate well into existing roofing materials like shingles and tiles. These solar cells use the same crystalline silicon technology as standard modules today. You do not have the permission to view this presentation.
