Measuring uncertainties

—

All results only refer to the test samples that were subjected to testing.

The extended total measuring uncertainty for the outdoor performance test is:

≤ 2.8 % (for irradiation levels above 700 W/m²)

The extended total measuring uncertainty (k=2) for the indoor performance test is:

≤ 2 %
