What will be the life cycle of the solar farm?

Solar panels generally come with a 25-year manufacturer warranty. Depending on the local environment they can generate power for 30 years or more, with only about half a percent of efficiency loss each year. Neoen intends to operate the Gilgandra Solar Farm for 25 to 30 years, and may consider replacing the whole equipment with newer technologies once the initial project has been decommissioned.
