Solar systems in Australia are designed to handle tough weather, but a few simple checks before storm season can improve safety and reliability. A quick visual inspection from the ground, checking your solar monitoring app and preparing your battery backup can help ensure your system is ready. Most systems do not need to be turned off before a storm, but knowing the shutdown procedure is useful in case damage occurs.
Should You Check Your Solar System Before a Storm?
Severe weather such as strong winds, heavy rain and hail can place additional stress on rooftop solar systems. While modern solar panels are designed to withstand harsh conditions, performing a few simple checks before storm season can help identify potential risks.
A visual inspection from the ground is usually enough. Look for anything that could become a hazard during strong winds, such as loose roof equipment, damaged wiring or large tree branches hanging over the panels.
If anything appears loose, cracked or damaged, it is best to contact your solar installer or a licensed electrician for professional inspection.
How Can You Check if Your Solar System Is Working Properly?
Before a storm arrives, it is helpful to confirm that your solar system is operating normally. The easiest way to do this is by checking your solar monitoring app.
On a clear sunny day, the solar production graph should generally form a smooth curve as the system ramps up in the morning, peaks around midday and declines toward the evening.
If you notice unusual drops in output or inconsistent production during sunny conditions, it may indicate a system issue that should be investigated before severe weather arrives.
How Can a Battery Help During Storm Season?
Homes with solar batteries can benefit from additional backup preparation when storms are forecast. Many modern battery systems include special storm or backup modes that allow the battery to charge to full capacity in preparation for a possible power outage.
Examples include storm preparation features available in several battery monitoring apps. These modes allow the battery to hold a full charge so stored energy is available if the grid fails.
Without a battery, standard grid-connected solar systems automatically shut down during a blackout for safety reasons and cannot power the home until grid power returns.
Do You Need to Shut Down Your Solar System Before a Storm?
In most situations, solar systems do not need to be shut down before a storm. They are designed to operate safely during normal weather conditions.
However, it is useful to know where the shutdown switches are located in case they are needed after damage or if emergency services provide instructions. Most systems include shutdown labels near the inverter explaining the correct procedure.
A typical shutdown sequence involves turning off the solar AC isolator at the switchboard and then turning off the DC isolator at the inverter.
