Cooking in the kitchen at Shirdi

 

  • April 2010: Gadhia Solar Energy Systems Pvt. Ltd. recently completed installation of an enormous solar steam cooking system, capable of cooking 40,000-50,000 meals per day. It is located at Shirdi Saibaba temple in Shirdi, Maharashtra, India. With nearly 30,000 visitors each day, the temple’s dining halls are some of the largest in India. The solar steam cooking system is comprised of seventy-three rooftop-mounted Scheffler reflectors of sixteen square meters each. The dishes concentrate sunlight on receivers that contain water, generating steam that is piped down to the kitchen for cooking purposes. To maintain constant focus with the sun, the dishes automatically rotate throughout the day after being manually aligned once each morning. The solar steam cooking system is retrofitted to existing liquid petroleum gas-powered steam boilers that are still used in the evening and during prolonged periods of inclement weather. Though the solar steam cooking system cost nearly $300,000, government subsidies reduced the temple’s portion to about $170,000. Liquid petroleum gas use has been cut by roughly 100,000 kilograms each year, for an annual savings of approximately $45,000. The temple should recoup its investment in three to four years. According to company founder Deepak Gadhia, the solar steam cooking technology was originally developed in Germany. However, the equipment does not contain imported components and is manufactured with local machinery and labor, creating much-needed jobs. Gadhia has adapted the system for use in India, and has installed 50 such systems of varying sizes over the past two decades. The March edition of CNN’s Eco Solutions program highlights the Shirdi Saibaba temple solar steam cooking system.
