Safety:
Review relevant OSHA and other safety standards before following these instructions. The installation of solar PV
systems is a dangerous procedure and should be supervised by trained and experienced personnel.
It is not possible for SunModo to be aware of all the possible job site situations that could cause an unsafe condition
to exist. The installer of the roof system is responsible for reading these instructions and determining the safest way
to install the roof system. These instructions are provided only as a guide to show a knowledgeable, trained erector
the correct part placement one to another. If following any of the installation steps would endanger a worker, the
erector should stop work and decide upon a corrective action. Provide required safety railing, netting, or safety lines
for crew members working on the roof.
