6 FAQs about [Photovoltaic panels resist hail disasters]

Are solar PV systems prone to severe hail?

The greatest contributor to insured losses on solar PV systems worldwide is severe hail. Severe hail events are forecasted to increase in frequency over time, emphasizing the increasing importance of designing and preparing for solar PV resilience to hail. Many areas are prone to hail events, and the level of risk a site faces may not be intuitive.

Can solar PV modules survive hail?

Historically, solar photovoltaic PV modules have survived the majority of hail events they have experienced. In areas that have experienced very large hail (greater than 1 ¾" or 44 mm diameter), however, hail has caused significant damage to PV modules. Some measures can be taken to limit damage to PV modules.

How does hail damage affect photovoltaic systems?

In particular, hail damage seriously affects photovoltaic systems. The severity of hailstorms as well as impact responses are important factors in mitigating loss, so the first research area that needs to be addressed is the resistance of photovoltaic modules to hail.

How resilient are PV modules to hail?

The number of busbars within a PV module was identified as a key factor influencing the module's resilience to hail impacts. Notably, mono-crystalline PV modules exhibited better resistance to hail loads compared to their poly-crystalline counterparts.

What is a hail impact on a PV module?

Hail impact is one of the severe loads that a PV module can experience during its lifetime. It can lead to severe damage, as shown in Fig. 1, due to a hailstorm in 2014 in Brisbane (Australia) with a nominal hail size of 25 mm.

What happens if a solar module fails before a hail impact?

Result of solar flash testing of PV modules before hail impact. It is essential to understand the direct correlation between breakdown voltage and power loss in solar cells. The sudden increase in current that occurs during a solar cell failure can cause overheating and irreversible harm.
