Solar Freaks

Subject: AS 5033

Hi Gerry,

I wish to make comment on the latest draft of AS 5033. I would like the question raised about individual isolation of solar panels which combine to form an output string voltage of up to 600volts DC, (leaving a lethal dc voltage potentials between panels and beyond to a pv isolator)

My question is why can’t we isolate these photovoltaic generators on our roofs to make safe for now and in the future anyone accessing a roof for work, cleaning or any Emergency services operator from doing their job safely.

For basic OH&S requirements we turn off a main switch in a switchboard to replace a power point.
We are also capable of isolating natural gas by turning off the incoming supply
Water may be turned off at the incoming mains to isolate any pressure entering a property
However to work on solar panels we only have the option of covering the panels.
I have seen garbage bags used to cover panels to try to stop them generating.
Neither option allows the panels to be isolated without lethal accumulation of panels existing. (note homeowners are required to clean their panels with water to increase efficiency and warranty). Water onto an electrical generator which can’t be isolated is a poor mix with deadly consequence.

I believe some sort of isolation should be made mandatory for solar panels. I urge you to view my website
I am the inventor of the remote solar isolator and as solar installations age there will be a greater need for isolation.

I am aware of numerous deaths which could have been prevented from solar electrocution if only a remote solar isolator was fitted.
Our solar industry is young and needs to be directed into the future.
