Sundrop Farms is a developer, owner and operator of high tech greenhouse facilities which grow crops using methods which reduce reliance on finite natural resources when compared to conventional greenhouse production.[1] Sundrop Farms opened its first pilot facility in Port Augusta, South Australia, in 2010 (operating as Seawater Greenhouse Australia Pty Ltd). This facility was originally designed as a Seawater Greenhouse. However, significant technology changes led to the Sundrop System, and the dissolution of the joint venture with Seawater Greenhouse Ltd.[2] Sundrop Farms commissioned an expanded 20 ha facility south of Port Augusta in 2016. Sundrop Farms has offices in London, UK and Adelaide, Australia. In October 2016, Sundrop Farms was operating greenhouses in Portugal, the United States and had another facility planned in Australia.[3]

Sundrop system
The primary inputs to a greenhouse are heat, electricity, water, and nutrients. The Sundrop System is a collection of technologies which, when used in combination, reduce the need for finite resources in these inputs versus conventional greenhouse production. In Sundrop Farms’ first facilities in South Australia, these technologies include concentrated solar power, thermal desalination, and steam-driven electricity generation.[4] This is the first combined heat, power, and water system powered by solar energy for greenhouse production.
