To reduce costs at Drury Orchards in South Australia, the company installed a solar photovoltaic system. The system helps offset peak electricity use in a company which spends around 70,000 kWh of electricity a year, at a cost of more than $18,000. The solar investment of $44,000 (including an $18,000 rebate) will help Drury save over $9,500 a year. Payback period? 4.5 years.
