Victorians who missed out on state-subsidised solar panels when the monthly allocation was snapped up within 90 minutes might get another chance.

Facing a backlash from frustrated consumers and solar panel companies, Premier Daniel Andrews said on Tuesday that the monthly allocation could be increased from around 3300 a month - if safety and quality can be guaranteed.

“I’m happy to look at expanding the amount of installs each month,” he said. “But I will only do that if I can be completely confident that high quality will be observed and safety will be observed.”

The Premier said it had been anticipated that the program “might grow and change”.

The rebate scheme was a major election pledge by the Andrews government, which promised to put subsidised solar panels on 650,000 homes to cut household power bills.
