Bankability/QA Testing
CFV Labs 40 Year PV Module Reliability Testing Program
-
PV Module reliability testing horizons need to correlate with financial modeling assumptions.
-
CFV Labs has developed a comprehensive 40 year bankability testing program based on IEC 63209 with technology specific customization.
-
Includes tests for material durability, cell degradation, mechanical durability and performance testing.
CFV Labs PV Module Module Backsheet Testing
-
CFV Labs has tested both older and newer backsheets to the new IEC TS 63209 backsheet testing protocol.
-
We find that both older and newer backsheets can fail this test.
-
Module construction is important, not just backsheet material.
-
Ongoing testing at CFV is pushing the expected horizon of backsheet tests out to 40 years.
CFV PV Module Bankability Program
-
Comprehensive bankability testing program based on IEC 63209 with technology specific customization.
-
Includes tests for material durability, cell degradation, mechanical durability and performance testing.
-
Third party BOM verification and build witness.
-
Report sharing with investors and IEs.
Cell Degradation Testing
-
Both LID and LeTID can be problems with newer technology modules, especially modules made from PERC cells, and some bifacial modules.
-
LID and LeTID operate via different mechaninsms and on different time scales and and may actually overlap, making disentangling the effects problematic.
-
CFV has a protocol designed to isolate and quantify each effect to the extent possible.
