Re: who amongst us have gone solar

one of the main reasons you cant get a stand alone system connected to the house is that if its conneted to the same circuits as the mains power then it can become a major safety issue.
if the standard mains feed in solar systems are set up to meet australian standards, when there is a problem on the mains supply side and there is a power outage the solar inverter shuts down to prevent power from the solar systems feeding back into the damaged lines.
eg - the HV conductors could be down in the street , the normal protection systems will quickly shut off power being supplied . if the solar systems are able to continue feeding into the mains (ie - from a battery bank) then the 230volts that leave your house roof can be converted to 11000 or 22000 volts through the street transformer and fed back to the broken cables with no isolation point creating a highly dangerous situation.
i am sure that the technolegy is out there to make battery back up sysems work with feed in but at the moment it probably is just not viable.
