The star sty leer initial requests these inputs concerning the target web site to start out on a design project: - A dimensioned read of the roof - Dimensioned locations of protuberances like vent pipes and chimneys - Rough positions of the planned solar battery arrays - The create and model variety of the star modules to use - The expected power output of the system - data concerning rafter breadth and spacing - most popular locations for supporting elements like the sun run meter, the load center and therefore the inverters THE method The star designer then performs the subsequent steps: 1. He decides wherever to position the arrays. this could be softened into many subordinate activities: a) He drafts the roof to scale, and incorporate all the protuberances at their precise locations (if the drawing appearance untidy, he drafts a callout read for individual roof slopes) b) He chooses slopes which is able to have most exposure to the sun throughout summer and winter. this can be sometimes a South-facing slope. He may additionally select the East or West-facing slopes, however there would be little loss in potency in comparison to arrays mounted on the South-facing slope. c) He tries to avoid locating the arrays on a North-facing slope since there's sizable loss of potency in doing this. d) He additionally considers shadows from tall components (like trees) adjacent to the planned installation and avoid putting arrays in them. NOTE: sometimes the positioning engineer provides a sun study, and easily following his recommendation for the planned location and orientation of modules is enough to satisfy the higher than conditions. Solar modules may be divided into 2 varieties, DC and AC. Multiple modules area unit assembled into arrays on metal frames. These arrays area unit known as strings within the case of DC modules and branches within the case of AC modules. e) A string will have between seven and twelve modules per array, whereas a branch will have between eight and fifteen modules. f) inside associate degree array, we tend to guarantee horizontal direction and around 3" clearance within the vertical direction (this might take issue with relevancy the create and model of star modules used). g) The star designer positions arrays on the roof with decent clearance from the ridges, overhang and different edges of the roof. on the create and model of modules and therefore the mounts used. h) when oriented the star modules, the star designer locates and plots the position of the attachment points on the roof, and defines the attachment mounts that got to be used. He positions the attachment points on the roof to be situated on the centers of rafters. commonly the star designer positions them at 48" O.C. NOTE: There are a unit differing kinds of attachment mounts the designer will use; the selection depends on the sort of roof. for example, he would use "Flapjack" for composite shingle roofs and "Fastback" for nearly any roof that needs a flashed install. The star designer estimates the placement of the rafters by compensative a line 24" from the correct or left fringe of the roof, then compensative multiple lines at distances of 48" until the top of the roof. He takes care to not position a module on one attachment purpose and to not let the unsupported fringe of a module be quite 16". capability of attachment mounts once deciding the full variety of attachment mounts required to support associate degree array. 2. following step is to draft the electrical connections from the star arrays to their electrical support elements, together with the metering panel. For this, the star designer finds the shortest route (avoiding diagonal crossings that make unpleasant aesthetics) on the roof and attracts one line to attach the arrays to a junction box, then on to The additionally follows any special directions that our installer-customers had noted on the positioning survey document. The star designer places the junction boxes at a convenient location close to the modules and in such a fashion on use a minimum length of wire from every string or branch. He ensures there's decent clearance round the sun run meter, load center and electrical converter for simple service access. IN CONCLUSION: As within the case of any on the face of it advanced activity, star style is straightforward to perform if one has procedural information and ample expertise.
