SunLink Sizer

 



Let Us Help You Size & Cost Your Module Mounting System
Eastwood Energy offers Sun-Link™ customers assistance in designing the layout of their flat-roof PV system. Eastwood’s engineers can help you determine, for a particular roof application, what method of hold down is most approrpiate. Sun-Link™Sizer can also help you determine the optimum module array configuration taking into consideration available roof space, desired energy output, shading effects, and any roof obstacles or unusual features. If you are interested in this service, please fill out the following questionnaire. An Eastwood engineer will contact you to shortly following your submittal:

1.Wind Exposure Category

Exposure B - has terrain buildings, forests or surface irregularities, covering at least 20 percent of the ground level area extending 1 mile (1.61) or more from the site.

Exposure C - has terrain that is flat and generally open extending 1/2 miles (.81 KM) or more from the site in any quadrant

Exposure D - represents the most severe exposure in areas with basic wind speeds of 80 miles per hour (mph) (129 km/h) or greater and has terrain that is flat and unobstructed facing large bodies of water over 1 mile (1.61km) or more in width relative to any quadrant of the building site. Exposure D extends inland from the shoreline 1/4 mile (.40 km) or 10 times the building height, whichever is greater.

Single-ply - Consist of a flexible membrane that resits displacment by the use of ballast, mechanical attachemtn, or adhesion to a roof deck (EPDM, PVC).

Built-Up - Build-Up-Roofs (BUR) are multiple layers of felt with inter-ply moppings of asphalt or coal tar assembled in the field to "build up" a finished roof assebly. A heavy application of asphalt or coal tar, which is then covered with gravel, is the typical surface finishing to these assemblies, primarily for fireproofing and ultra violet protection.

Metal Roof -Typically steel, aluminum or copper metal roofing. Most metal roofs are installed in sheets, but can also be installed in shingles, the most popular being aluminum or copper.
