How Common Is Hail Damage To Solar Panels
Just because it’s going to hail doesn’t mean you need to fret about your solar panels. As the solar panels we use at Global Solar Solutions are also used all around the world and are constructed with tempered glass they are designed to withstand smaller hail travelling at up to 80 km/hr. While this affords us some peace of mind come storm season it doesn’t mean they are going to stand up to the large hailstones we can experience. Solar power hail damage can still occur no matter how tough the panels we use are.
Hail damage to your solar power system can be a serious issue if you want to get the most out of your solar power panels. While it is extremely rare to see more than 1 or 2 panels damaged by hailstones even a single break can drop the efficiency of your system significantly which means you get less power and less savings. While storm damage is the number 1 cause of solar system repairs both in Australia and across the world, solar panel hail damage is a rare occurrence as it is most often the winds that cause damage to your roof and in turn to your panels.
If you are interested in seeing for yourself how resilient solar panels can be you can take a look at some research that was carried out by the National Renewable Energy Laboratory (NREL). They carried out a survey of 50,000 solar photovoltaic (PV) systems that were installed in the U.S between 2009 and 2013. During this survey they found that only 0.1% of the panels installed were damaged or malfunctioned each yearly review. Keeping in mind these findings include malfunction it paints a great picture for those looking to get longevity out of their solar power systems.
NREL also experienced a devastating hail storm in 2017 at one of their campuses that caused significant damage to car windows and even left dents in roofs across the area. When inspecting the 3,000 solar panels on their campus they found only 1 to be broken. This is a great demonstration of the toughness that solar panels possess and the infrequency of damage caused by violent weather.
So while you don’t need to call us out every time there is some hail in your area it does pay to monitor the output of your solar power system at your inverter to make sure there are no changes after a violent storm. Luckily a lot of modern solar systems come with apps to help you easily monitor their condition which makes this an easy task to add to your list of things to do. Even if you haven’t been experiencing storms we always recommend checking on your system on at least a monthly basis to make sure everything is performing as it should be.
