Composition Shingle Solar RoofsThe first consideration for all solar installations is picking the best roof face to use for your system. Mounting feet are the primary component of a roof top solar installation. The feet are installed by a licensed roofer on all of our retrofit solar installations. The feet are mounted to house a solar rail which will then house the solar electric panels. The feet allow 2' of over run on the ends and 4' to 6' for the entire row span. WaterproofingUsing standard roofing penetration waterproofing materials, which includes "Henry's" and tacky tape. Feeder Drill Holes Once the rafters and the layout of the feet are determined we will drill feeder holes to make bolting the feet to the rafter smooter, safer and stronger. 5/16" by 3" lag screws are used per mounnting foot. Solar Rails Attach to Solar Mounts The solar rails are laid along the solar mounts to check for distance. The number of solar panels is calculated by width or height depending on if your installation is portrait or landscape. For example, we consider the Mitsubishi Solar 185 watt panel to be 33" by 66", which is slightly bigger than their actual size to account for mounting parts. The rails are then drilled above each solar mount and then attached with washer and bolt.
