Cold front timelapse from space
A satellite captures a massive cold front spilling across southern Australia between 10-12 July 2015. Vision: Japan Meteorological Agency.
Sub-zero temperatures were reported around Melbourne on Sunday, including minus 5.3 degrees at Coldstream, near Lilydale, and minus 2.5 degrees at Viewbank.
The cold snap caused water in panels to freeze and expand, resulting in snapped and split panels and broken frost valves.

John Willis from John Willis Plumbing in Lilydale, where temperatures were also below zero, said he had seen several broken solar panels over the weekend and that quality varied among manufacturers.
"There are various manufacturers of them, and some of them arenāt really up to the job of the frost.

Scott Edwards from S.A. Edwards Plumbing in Eltham said he couldnāt keep up with demand over the weekend.
āIāve just left one job and Iām going to another now. This generally doesnāt happen every winter, just when we get bad frost like over the weekend.ā
Mr Edwards said quality solar panels with a glycol antifreeze system were generally more durable than cheaper models favoured by builders.
āThere definitely has been one lot of units that Iāve done more of than others. Generally the ones that are bursting more often than not are the base model that builders put in.ā
Simon Marchione from All Sorted Plumbing in Keilor Downs said he had been to eight solar panel jobs over the weekend and that split panels could cost up to $2500 to replace.
āIāve never seen anything like this,ā he said.
āThereās a device on solar panels called frost valves. They allow a bit of expansion in the panel itself by allowing water to drip out of the panel. But weāve seen panels with frost valves installed where itās still happening.ā
āI donāt think itās a quality issue. Itās more or less I donāt think anybody expected for Melbourne to be so cold. They really arenāt made for our changing climate.ā
Mr Marchione said damaged panels he had seen had caused no building damage and were only leaking water on roofs.
In 2008, the Rudd government offered $8000 rebates to households installing solar hot water power but scrapped the scheme due to soaring demand.
The rebate was part of of the Energy Efficient Homes Package, which also included a controversial home insulation program that resulted in the death of four workers.
