“More customers will see solar as a cost-effective way to meet growing energy demands, especially as the price of conventional grid power increases in Australia. Through this partnership, SunPower and Diamond Energy are poised to deliver affordable, renewable electricity services that cover everything from the generator to the household electricity meter. We look forward to this new venture and expect it to serve as a model for SunPower's continuing evolution into a complete energy solutions provider.”

“This investment by SunPower supports the growth and strengthens Diamond Energy for the upcoming clean energy revolution,” said Diamond Energy managing director Tony Sennitt. “We generate change here at Diamond and through this relationship we will be able to bring the world's most efficient and reliable solar technology to a broad range of households and businesses throughout Australia at affordable prices. We look forward, with SunPower's support, to expanding the business into a shining, renewable example of what can be achieved when innovative value is delivered to customers.”
