What happened
A hail storm this week damaged photovoltaic systems in Italy's Marche region, with thunderstorms and damaging winds also reported along the Adriatic coast. Damage was described as highly localised. Of about 200 systems under one manager, one was damaged, with losses estimated at about €80,000 to €90,000. The same account said a similar storm in early June destroyed two systems in Monteroberto, near Jesi, while a system a few hundred metres away was unaffected.
A system near San Benedetto del Tronto was said to have all-risk cover under the Conto Energia scheme, and an insurance claim had been filed. Modules at that site were described as certified for mechanical resistance but still damaged. Hailstone size was not reported. Other media and social media posts were said to show further damaged systems, without further detail here.
Contributing factors
The account said hail damage to photovoltaic systems had been rare for many years but had increased over the past two or three years, and that recent weather had been more intense than events the modules had previously withstood. It also said many policies exclude photovoltaic systems and that newer, non-subsidised owners do not always buy dedicated cover. These points are one person's experience, not a confirmed cause.
Lessons learned
- Owners should check whether their policy actually covers hail damage to photovoltaic equipment, and arrange dedicated cover where a general policy excludes it.
- Certification for mechanical resistance does not remove the need to plan for hail more severe than past events at the site.
- Because hail can destroy one array and spare another nearby, each site still needs its own inspection after a storm.
