.> installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. The solar panels are 1 Yz'thick and mounted 4Yz" off the roof for a total height off the existing roof of 6". At no time will the panels be mounted higher than 6"above the existing plane of the roof. , 3. Maximum allowable pullout per lag screw is 307 Ibs/inch of penetration as identified in the National Design Specifications (NDS) of timber construction specifications for Southern Pine. Based on our evaluation, the pullout value, utilizing a penetration depth of 2�/z", is less than the maximum allowable per connection and therefore is adequate. 4. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph A above, using the wind load uplift procedures of ASCE 7-10 and is specified below. The following values have been verified by in- house testing and the mounting hardware manufacturers' data, which are available upon request. Panel support connections shall be staggered to distribute load to adjacent members.
