Notes:
1) Values shall be measured at Standard Test Conditions after Preconditioning according to IEC Standard61215, Section 5, or after Light-soaking according to IEC Standard 61646, Section 10.19. Modules maybe light-soaked by the manufacturer prior to submitting the modules to a testing laboratory. The testinglaboratory shall verify the module stabilization in accordance with IEC Standard 61646, Section 10.19.
2) Values shall be measured and calculated according to IEC Standards 61215 and 61646, Section 10.4.
3) Values shall be measured in accordance with IEC Standards 61215 and 61646, Section 10.5. For BIPVmodules the measurements shall be made using the mounting specified below.
4) Values shall be measured at low irradiance according to IEC Standards 61215 and 61646, Section 10.7.
5) Values shall be measured at STC and NOCT according to IEC Standards 61215 and 61646, Section 10.6.6) The submission of this data is optional.
