Solar Steam Generating with a big dish sg4

A BIG Dish SG4 Solar of 520 m2 is being installed at MSA-Muni Seva Ashram ( a NGO near Vadodara and the system would generate 400 kg/hr steam to supply for process heating, cooling and steam cooking for hospital run by MSA . Earlier the steam was being generated and supplied by 100 Scheffler Concentrator of 12.5 m2 each which was supplied by Gadhia Solar. The advantage of BIG Dish SG4 Concentrator is that it requires 1/3 the foot print on ground and only half the reflector area.
