Johannesburg
Question: A manufacturer has presented a new type of insulation (backsheet) for use on PVmodules.
The insulation material (plastic) is sprayed onto the back of the module. After it is hardened, a
second layer is sprayed onto the module. These 2 layers passed all tests of IEC 61730-1 and -2.
# g/ {' T1 F8 ?6 Q/ Y4 DBasic standards (e.g. IEC 60364-4-41 clause 4.12.1) do not allow varnish/paint to be used as
insulation. Spray-on insulation is something like paint but IEC 61730-1 and -2 say nothing against
such an insulation.
