"Our plan is fully costed and will add less than $10 per year to Victorians' electricity bills, not the $100 claimed by the government," says Brad Shone, ATA's Energy Policy Manager.

Mr Shone says ATA's proposal is based on international experience.

"Germany has installed 400 times the total solar capacity of Australia, over the last seven years, at an additional cost of less than 1% on household electricity bills".

Mr Shone says ATA's proposed gross-metering feed-in tariff will also provide the financial incentive to deliver over 100,000 solar roofs across Victoria.

"Not only is ATA's scheme affordable for consumers, it will also guarantee solar panel owners can recover the cost of their solar installation within ten years".

Mr Shone says the government's claim that their net feed-in scheme will also result in a ten year payback is difficult to believe.

"ATA's figures show that payback times will be over 25 years for a typical solar system, under the government's proposal".

"It's not too late for the government to introduce a world class, effective gross-metering feed-in tariff that will drive large scale up-take of solar and help Victorian families play their part in tackling climate change," Mr Shone says.
