Philadelphia Solar’s module passed Dynamic Mechanical Load Test (DML)


Test Report no. 4790324433 issued by UL laboratories has shown astonishing performance of PHS modules undergone dynamic mechanical load test. Both model types of mono-facial and bi-facial were tested.

Modules were exhibited to 1000 Pa of dynamic load directed by pistons for 1000 cycles. Tested modules haven’t shown an evolution of micro-crack, module fracture nor dielectric breakdown. Power degradation after test reached -0.14% of original power for bifacial product and -0.019% for mono-facial one.

It is good to mention that PHS modules withstand a static load of 5400/2400 Pa for front and back side respectively.

PHS do recommend its customers to follow the instructions written in installation manual to reach the optimized performance of PV modules.
