Energy 11 16pm feb 4. The south australian government will roll out at least 50 000 home solar panels and batteries across the state in a plan to create the world s largest virtual power plant. Solar panels work by converting sunlight into electricity so the cleaner your panels are the more efficiently they ll be able to generate clean energy for your home or business. Since sunpower s panels are the most efficient on the market 1 they ll make more energy than competing panels in a variety of low light situations but any.

Unless alternative environmental factors are at play solar panel fires are caused by one thing dc arc faults. Dc arc faults are quite simply electrical energy flowing through an air gap which in turn creates an electrical arc. Microinverters and dc optimised systems were developed more than 10 years ago to prevent solar fires caused by dc arc faults. In almost all rooftop solar installations there s a gap between the solar panels and the roof.

Figures from the electricity safety watchdog show that in the two years to june 30 there were 24 incidents caused by defective solar panel installations. There are many solar retailers and installers throughout australia who provide safe solar solutions. When choosing a supplier ensure that they are familiar with safe solar technologies and that the systems they install are rapid shutdown compliant a safe solar installer will help you choose the right system for your home or business and explain the many benefits of safe solar technologies. As part of the study a survey of australian based solar installers was conducted and it was found that over 60 of these installers indicated that rooftop dc isolators were a primary cause of solar related fires in australia.

When fire departments arrive to a house fire where solar panels are interconnected to the power grid they have two options to kill the power on your solar panels and both ways are very quick. Normally this is a good thing as it allows air to circulate and help cool the panels. So what are dc isolators. Dc isolators are switches that are found on the side of photovoltaic panels.

Faulty or poorly installed solar panel systems have sparked fires at more than 20 homes in wa in the past two years. Is my solar system a fire hazard. But it does make it possible for leaf litter to accumulate under the panels and create a fire hazard.
