The Complete Guide For Solar Panel Design Systems - Part 1 Design I Modular The initial design simple yet robust, and comprises only two elements, 12 inches and slat. As shown in Figure 1, the panels are mounted to slats that are joined by feet. The grooves the actual foot component shown in Figure 2 constrain the slats from rotation. A particular stainless steel bolt constrains the slat in the vertical as well as lateral axes. As with traditional mounting systems, the panels are glued to the slats. The installation costs are greatly reduced because there isn't on-site customization for oddly shaped roofs; that is, the panels can be arranged several configurations to adapt to roof cover. When mass-produced, the foot and slat components cost less then $3 each, along with the total cost per panel is about $18. For smaller-scale production runs, a wood/plastic composite lumber could be utilized as an alternate material to injected molded plastic. This composite material is corrosive-resistant and could be cut and drilled much like wood. This design meets every one of the functionality requirements named previously, except for that 90 mph wind rating of Massachusetts building codes, which has yet turn out to be proven. Due for the complications in theoretically modeling the system, an experimental model need to made of air flowing over the top of commercial buildings, and the lift and drag forces on the software must be measured. Because the of the panels is not sufficient for keeping the system stationary, the corners for the array has to be constrained by cable stays that can be mounted to the side walls of the roof. The aims of this experimental test are to discover the necessary constraining forces or even find any system complications such as resonance frequencies that may arise in storm concerns. Once the forces are calculated, finite element analysis software can be used to specify the contact stresses in the glass sheets. The high wind-speed conditions on the roof of a poster building is actually going to simulated in the MIT water tunnel. The schematic The tunnel is 1.2 meters long and has a cross part of 0.5m x 0.5m. Water flows over the bulkhead to simulate captivating around the roofing of a commercial building. The one-third-scale panel from the experiment is really a stainless steel plate of dimensions 5.64m x 0.32m x 0.008m. When compared to the water flows over the bulkhead, water can flow above and below the panel as there is a clearance of 9.01m to simulate ventilation under a panel. To vary the position of the panel, the space between the panel and bulkhead can be adjusted doing 0.64 yards. Design II Corners For every design strategies revisions for other applications. In this particular case, customer has dictated the coming of the three subsequent blueprints. MIT facilities recently received a grant to solar panels on college campus.2 The supplier of solar cells uses various panel sizes that are not compatible with the Modular creation. It would therefore be necessary to have shorter or longer slats depending towards the specific sized the panel as inadequate one industry standard. This issue spurred the concept of having a configuration that isn't constrained together with specific proportions of the section. Removing the slats and modifying the foot component created a design whereby the panel is only constrained as corners. The corners of the panel are sandwiched in between two symmetric parts. To reduce possible concentrated stresses about the extremely inelastic glass panels, a thin layer of neoprene can be inserted between plastic and glass. Not hard to install efforts will also reduced this kind of design since gluing phase is eliminated. The drawback is that a small portion on the photovoltaic cells are blocked off from sunlight. In addition, the will be not as robust when the first: The slat backing does not fully secure the panels. Under high winds, vibrations may dangerously strain the panels, reducing existence of the photovoltaic solar cells.
