2. If the roof structure more than 30 years old, please specify the rafter, truss sizes and spacing, to a
qualified engineer as engineering calculations may be required if the roof structure is non-standard.
3. It is strongly recommend that engineering details of the PV panel mounting to the roof framing members
be obtained prior to installation. Several well-engineered mounting systems are now available for installers
to use. These designs often include detailed engineering specifications and details. Installers who use
their own designs will need to provide their own details and engineering calculations with their design.
4. The PV module is to be mounted over a fire resistant roof covering rated for the application.
(b) If the array is ground mounted and the mounting structure is unfamiliar to the local jurisdiction and is more
than two meters above ground, it may require engineering calculations and council approvals.
(c) The maximum number of series and parallel modules are recommend as follows:
The number of series module (N) = Vmax system/ Voc (at STC)
The number of parallel module = 1 + I ( Max. over-current rating)/ Isc( short current)
VII. ELECTRICAL RATINGS
Rated electrical characteristic are within 10 percent of the indicated values of Isc, Voc, Pmax under Standard
Test Conditions (irradiance of 1000W/m
