Hail damage resistance—testing in accordance with Approval Standard 4470 (steel balls) for flexible PV modules and ANSI/Approval Standard 4473 (ice balls) for rigid PV modules. Electrical safety —both flexible and rigid modules must meet the electrical safety requirements of IEC/EN 61730.
Although baseline hail testing has been performed on solar modules since the 1970s, there is a lack of field-representative testing to support module deployment in hail-prone regions. PVEL''s hail stress sequence addresses this information gap. The test is designed to help: • PV module buyers benchmark the hail resistance of
Hail risk in solar projects is increasing due to a perfect storm of market and technology changes. On the technology front, PV modules are becoming less hail-resistant over time as manufacturers …
Some measures can be taken to limit damage to PV modules. This resource outlines these measures and best practices in the design phase and operations and maintenance phase and provides resources for evaluating hail risk.
Solar PV systems have been the most heavily impacted, with an increasing frequency of major loss events and associated insurance claims. ... accompanied by deductible requirements of up to $1 million or 15% of the physical damage limit. More critically, insurance coverages for hail damage have been capped between $15 million …

The modules have passed the 35 mm hail test and requirements for IEC fire protection. Their mechanical resilience is also purportedly high, according to Trina Solar.
Among the factors that determine solar PV system performance and longevity, the module is the most critical component. Many factors must be considered when choosing a module, including quality, safety, weather strength ratings (e.g., wind, snow, hail), fire ratings, Buy American Act (BAA) compliance, and others.
Hail risk in solar projects is increasing due to a perfect storm of market and technology changes. On the technology front, PV modules are becoming less hail-resistant over time as manufacturers push the value-engineering envelope with larger format products and thinner front glass.
These include enabling near-field or in-field PV system repair, evaluating end-market technology solutions, reviewing policies that incentivize or mandate PV recycling, analyzing PV module composition and toxicity, developing end-of-life best practices, and publishing an end-of-life database to support long-term planning.
This white paper explains how PVEL''s hail stress sequence replicates the impact energy of natural hail and simulates field conditions to assess PV module durability. The …
Hail tests on photovoltaic (PV) modules should be beyond the conventional testing. • Power reduction of 21.47% is observed in glass to backsheet PV modules under hail. • PV modules with front glass thickness of 4 mm can withstand severe hail damage. • Use low wet-leakge current resistance modules for high hail-prone …
IEC 61215 Certification Testing for solar modules, fast and reliable service. ... The IEC 61215 standard outlines many required standards that comply with the actual requirements of the PV industry. It aligns the requirements for different crystalline Si technologies for manufacturers and provides a clear structure of general requirements and ...
Mitigating Utility Solar Climate Risks with Hail-Resistant PV Modules. At Trina Solar, we take hail risks to PV modules and the solar industry as a whole …
Trina Solar has published an analysis of the high mechanical reliability of its Vertex 670W module, following the product''s exposure to six rigorous tests, including 35mm hail, non-uniform snow ...
Basically, certifications per se do not tell much about the quality of a module. If you buy a solar module with IEC 61215/ 61730/ 61701 etc. certifications, it means that the certification-holding manufacturer managed to produce a few modules of that type that passed a standard''s (e.g. IEC 61215) tests at the time of applying for …
damage to solar PV plants, a meticulous plan could help mitigate losses. PVEL''s Hail Stress Sequence replicates the impact energy of natural hail and simulates field …
PV Evolution Labs (PVEL), an independent test lab for the downstream solar industry and member of the Kiwa Group, published its 2024 PV Module Reliability Scorecard.This 10 th edition of the …
Virtually all module designs pass the hail test in IEC 61215- 2, which subjects modules to 11 impacts of a 25-millimeter (1-inch) ice ball traveling at its terminal velocity; this basic
US solar tracker manufacturer FTC Solar has launched its Automated Hail Stow Solution, an automated programme to stow PV modules ahead of hailstorms, to minimise damage from extreme weather events.
For everyone else, though, the increasing frequency and severity of hailstorms with larger and denser hailstones are causing concern and re-evaluation of PV product offerings. Since the solar sector often bears the brunt of hail-damage-related costs, PV module manufacturers have been hard at work integrating advanced technologies …
In the 35mm hailstone test, power attenuation of single-glass 670W modules was just 0.17%, and no attenuation was detected in dual-glass modules. Under the stringent requirements of the IEC 61215 series, the hail test of Trina Solar''s Vertex 670W modules simulated the shock of hail on the modules'' surface.
The following technical recommendations can be added to project specification requirements of a new system or used to assist in planning for a modification to an existing solar PV system. This webpage covers flooding topics related to on-site ground or elevated systems (e.g., solar PV canopies) for both new and existing systems.

Hail storms represent one of the hazards a PV module might face during its lifetime. Consequently, all IEC approved solar modules are required to withstand a specific impact from hail, as defined by the "Design qualification and type approval" for crystalline PV modules, IEC 612151).
Hanwha Solar is the first solar module manufacturer to have signed up for the HW4 test at German testing institute TÜV Rheinland. During the HW4 test, hail stones with a diameter of 40mm strike the solar modules at 27.7m/s, or approximately 100km/h. Following the simulated hail storm, the modules are thoroughly tested for performance ...
