General
You must understand and follow all applicable local, state, and federal
regulations and standards for building construction, electrical design,
fire, and safety, and must check with local authorities to determine
applicable permitting requirements before attempting to install or
maintain PV modules.
Rooftop PV systems should only be installed on
dwellings that have been formally analyzed for
structural integrity, and confirmed to be capable of
handling the additional weighted load of PV system
components, including PV modules, by a certified
building specialist or engineer.
For your safety, do not attempt to work on a rooftop until safety
precautions have been identified and taken, including without limitation
fall protection measures, ladders or stairways, and personal protective
equipment (PPE).
For your safety, do not install or handle PV modules under adverse
conditions, including without limitation strong or gusty winds, and wet or
frosted roof surfaces.
The flat-plate PV module construction consists of a laminated assembly
of solar cells encapsulated within an insulating material with a rigid glass
surface and an insulated substrate. The laminated assembly is supported
by an aluminum frame that is also used for mounting the module. See
Figure 1 for an illustration of the PV module components.

Electrical
PV modules can produce current and voltage when
exposed to light of any intensity. Electrical current
increases with higher light intensity. DC voltage of
30 Volts or higher is potentially lethal. Contacting the
live circuitry of a PV system operating under light can
result in lethal electric shock.
