The Sundrop Farm Project will harness solar energy to desalinate seawater to produce fresh water for the crops, generate heat to maintain the correct glasshouse temperature and produce electricity to power the facility.
15 Hectares of mirrors (23,000 individual mirrors) focused on the 126 metre tall solar concentrator tower.
The tower fed super-heated steam to 3 places – multi effect desalination plant (MED), bypass condenser which maintained the 95 degree water stored in the two thermal storage units (1 tank at 42ML and 1 @ 25ML), and finally to the 1.5MW steam turbine to develop power for the site.
Then we had 20 Hectares of greenhouses (4 even sized houses) where hot water was passed through approximately 50km of heating pipes for the winter and evaporative cooling was used in hotter months via cardboard paneling with sea water passing over them – flushed with fresh water once a week to reduce salt build up.
3 ponds – fresh, sea and brine. Fresh water 100% sealed with floating roof to maintain cleanliness of water.
