Twenty percent of solar panel installations in Australia are dangerous, according to the National Electrical and Communications Association – a shocking statistic for homeowners across the country. Identifying potential solar system dangers could protect you and your family, especially as rooftop solar panels pose a significant safety risk when wires are exposed or water damages your system. Here are seven hazards to keep in mind during solar maintenance.

1. Overheated Cables

Unprotected, loose cables that lay across the roof of your home could present a health hazard. Cables need to be properly enclosed and secured so they don’t become damaged from the sun. If your cables overheat they could cause a fire on your property.

2. Contaminated Surfaces

Solar panel surfaces can become contaminated over time, something that can reduce your PV system’s performance. Solar systems that are heavily soiled with bird droppings could limit solar output and cost you hundreds of dollars in repair costs.

3. Damaged Connectors

Connectors on PV systems are exposed to environmental factors like dust and adverse weather. If your connectors are damaged or corroded they could increase the risk of a fire.Solar system servicing ensures your connectors are working at optimum efficiency.

4. Storm-Damaged Solar Panels

Solar panels damaged in a storm, cyclone or flood could be dangerous. PV systems will generate voltages, even if the network supply has been turned off. The government of Queensland recommends that homeowners call in a professional after a storm.

5. Faulty Components

Faulty components such as junction boxes, isolators and meters could render your PV system useless. Regular maintenance will identify any faulty equipment so you can quickly replace dated components.

6. Water-Damaged PV Systems

Water damage could seriously affect the efficiency of your solar system, especially if it enters the conduit. A professional will be able to spot any signs of water damage in your system before it causes a significant problem.

7. Ineffective Grounding

Grounding is one of the essential components of your solar system. A ground fault could reduce energy generation and even shut down your solar system completely. Grounding should be checked by an engineer on a regular basis to mitigate any potential risks.

Solar panels can save you money and reduce energy consumption. However, regular solar panel maintenance is crucial if you want to safeguard your system against hazards like fire and water damage. A trained engineer can identify problems with poorly installed and faulty solar systems in Australia, providing you with peace of mind.
