26 July 2012 โ€“ Sungevity Australia is up and running, offering RoofJuice to Australian homeowners. The business, an offshoot of California-based Sungevity, is the first solar company in Australia to offer zero-cost rooftop solar, teaming up with local company Nickel Energy to offer pay-as-you-go leasing deals.

The model allows customers to buy large solar systems โ€“ up to 5kW or around $12,000 โ€“ for no upfront cost and receive instant savings on electricity costs.

Sungevity Australia spokesman Alexander Kinross-Rowe said the roadblock to more residential customers taking up solar energy had been the upfront costs.

โ€œWe believe we are the first in Australia to provide power-purchase agreements to residential customers,โ€ he said.

And while the company was starting in New South Wales and Queensland, it planned to be national by the end of the year, Mr Kinross-Rowe said.

The companyโ€™s website, www.sungevity.com.au, promises a firm solar iQuote within  72 hours.

Nick Lake, the head of Nickel Energy who will run the joint venture, said earlier this year that the new model was a โ€œmassive game changerโ€.

โ€œThis is returning the market to the way it was,โ€ he said.

โ€œInstead of outlaying capital cost and providing their own electricity, householders will go back to buying electricity from a supplier, only this will be cheaper and cleaner. We think it will take solar into new markets.โ€
