Sharp Contrast in Solar Power Generation Amounts on 2 Islands (page 5)
Panels inspected on-site
In Adler Solar Works' service, the seriousness of the effect of the micro cracks in cells is evaluated and presented to clients in four levels from "A" to "D" based on the results of the I-V characteristic measurement and EL test (Fig. 5).
"A" is mostly a favorable level, "B" is inferior to A in the number of cracks and I-V characteristics, while "C" and "D" are levels corresponding to defects. Such evaluations are indicated in different colors such as green, yellow and red.
According to Adler Solar Works, requests to implement solar panel inspection on-site using the "PV test car" are gradually increasing.
