It is now established practice, before embarking on the construction of the PV facility, to carry out a sample check on the modules in order to certify their good condition and to confirm the warranties given by their manufacturers.
More and more companies undertaking the construction of such projects, necessarily include quality control in the agreements they sign, stipulating specific criteria that render the inspection results acceptable or not.
The electroluminescence test (EL test) can diagnose serious defects that are not visible during the visual inspection and cannot be proven otherwise.
This confirms that the modules intended for installation at the facility do not have microcracks caused during the shipping process, as a result of poor packaging and transportation.
Equally important is the corresponding inspection following the installation of the modules in order to ascertain that they sustained no damage during installation.
Microcracks constitute a critical factor in the final performance both of each module and of the entire string.
