19 IEC 61215 Tests to Identify Quality Solar Modules

IEC 61215 is the industry standard that defines the design and qualification of silicon PV modules for long-term operation in open-air, terrestrial applications.. With a long history dating back to 1993, the IEC 61215 standard

Basic Understanding of IEC Standard Testing For

The performance PV standards described in this article, namely IEC 61215(Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design

Micro-Fractures in Solar Modules: Causes, Detection

With the help of an ELCD test, a PV manufacturer can evaluate the structural quality of solar cells and any other possible defects caused by improper handling of photovoltaic panels. Nowadays, the majority of large solar panel

Hail Damage Mitigation for Solar Photovoltaic Systems

Modules only need to pass a test where they are visually undamaged and lose less than 5% of power from 11 ice-ball strikes at 51 mph of 25 mm diameter (1") hail to be "hail certified."

Protecting solar panels from hail—the thicker the glass, the better

Currently, 3.2 mm is the standard thickness for glass front panels in commercial PV modules. Based on the results of this study, this thickness is not suitable for use in hail

Micro-Fractures in Solar Modules: Causes, Detection and Prevention

With the help of an ELCD test, a PV manufacturer can evaluate the structural quality of solar cells and any other possible defects caused by improper handling of photovoltaic panels.

Can your solar project weather a hailstorm?

Virtually all solar module manufacturers use glass for the top surface of the panel — and they all pass the same tests intended to represent impact from hail. And yet, hail can still damage solar modules.

6 FAQs about [Photovoltaic panel glass test]

What thickness of front glass is used in PV modules?

In industry, mainly 3.2 mm thickness of the front glass is used in traditional PV modules. Results of the analysis show that PV modules with a front glass thickness of 3.2 mm are exemplary with hail impact up to 35 mm diameter with a velocity of 27 m/s.

Are glass-glass PV modules a problem?

Unfortunately, glass-glass PV modules are, similar to regular PV modules, subject to early life failures. A failure of growing concern are defects in the glass layer (s) of PV modules. The scale of decommissioned PV modules with glass defects will increase with the development of solar PV energy [ 7 ].

How much energy does a double-glass PV panel use?

The double-glass PV specimen has an invested energy of 1633 kWh/per module (986 kWh/m 2) [ 63 ], whereas the invested energy for the glass repair resin is calculated at 1.51 kWh/per module reparation [ 63 ]. Obviously, the do-nothing alternative does not require any energy investments.

Why do PV modules need glass panels?

The replacement of the back sheet layer with a glass panel drastically reduces the proneness to water penetration. Ingress of water (vapor) at glass-glass PV modules is negligible and restricted to the edge area only [ 18 ].

Do PV modules with glass defects meet safety and performance standards?

The probability of (in)direct degradation and electrical shocks by glass defects, make that PV modules with glass defects do not meet the safety and performance standards set by the International Electronical Committee (IEC 61215 and IEC 61730) [ 41] (see Appendix A for more details).

Are glass-glass PV modules more expensive than regular GBS modules?

While there are no technical disadvantages to glass-glass PV modules [ 10, 19 ], in general glass-glass PV designs are more expensive than regular GBS modules due to the use of an additional costly glass layer and the increased weight that may lead to higher costs for support structures.
