Qualification Testing • UL 1703, IEC 61646, IEC 61730 – Don''t be fooled…these are really standards built around crystalline PV failure modes with a dash of thin-film specific conditioning tests thrown in. – Nevertheless are remarkably good stress tests for identifying
Other PV failure modes, including failure in the bypass diodes 12, permanent shading 13, or shunting (increase in the resistance of the cells) 14, have been identified as likely to accelerate PID.
4.2. Electric Mode. The electric mode of failure can be observed as an independent event or the outcome of a mechanical mode failure. Again, ISCs are the common outcome of this mode of failure. The major electric signature of ISCs is the rapid drop in battery voltage due to contact between the internal active components of a battery .
Optimum PV module test design was assumed to have each test procedure specified in a way, that it exactly covers or provokes one distinct failure mode. If new failure modes were observed in field applications, new test procedures shall be designed, and added to the test specifications. In, a table lists common module failure …

During the first 10 years in service, the chance of failure within a PV system is approximately 10%. Inverters and other electronic devices account for 85% of all those PV system failures. Only about 1 in 2000 modules will fail during their warranted 25-year life. The system components most likely to fail are the ones with complex electronic circuitry.

Degradation of silicon solar cells is dominated by four modes: potential-induced, light--induced, wafer cracking, and metal corrosion. • These modes affect the cells in different ways and may range from almost no loss of power to complete loss of power. 4.1. Introduction to the Physics of Photovoltaic Devices
In order to characterize the degradation of solar modules, it is necessary to systematically recognize common signatures, such as cracks and corrosion. This information can be useful in a multitude of ways, such as comparing failure models of different brands or types of cells. The process of electroluminescence imaging can illuminate these signatures such …
