47 7.1 SOLAR THERMAL DEVELOPMENT PROGRAMME 7.1.1 Research & Development Solar Thermal Development Programme includes implementation of R&D and technology transfer projects, support for Regional Test Centres (RTCs) for solar thermal devices/ systems and technology resource centres, and other associated activities related to  resource  assessment,  feasibility  report  preparation,  capacity  building  through  seminars,  symposia  and  round-tables,  and technical documentation. 7.1.1.2 The main focus of the programme is research, design, development, standardization and demonstration (RDDSD) on all aspects of solar thermal energy technologies covering new materials and components, new processes and products, new concepts, production and testing equipment, design tools, software and manuals, etc. Keeping in view the overall role of the Ministry for augmentation of power generation capacity in the country through renewable energy sources and large untapped potential of solar thermal energy in industrial sector, solar thermal power generation and industrial process heat systems are perceived as the priority areas for technology development. 7.1.1.3 Six R&D projects were completed and three completion reports have been received in the Ministry. Follow up action for obtaining the completion reports for other projects is underway. Four projects are under implementation. The Ministry has received 18 new proposals. 7.1.1.4 The  on-going  R&D  projects,  sponsored  by  the  Ministry,  on  different  aspects  of  solar  thermal  technology,  were reviewed during the year for their progress to achieve sanctioned objectives. A project was sanctioned to IIT Bombay and M/ s. Clique Developments Pvt. Ltd., Mumbai, for developing and installing a 160 m2 parabolic dish concentrator for use in milk pasteurization at a dairy at Latur, Maharashtra (Box 7.1). The solar dish, the first of its kind in the country, has been developed, constructed and erected at the site. The integration of the solar system with the existing heating system at the dairy has been completed and performance monitoring of the system is in progress. In another project to World Renewable Spiritual Trust, Mumbai, a 16 m2 parabolic dish has been developed and installed for steam cooking applications at Brahmkumari Shantivan Complex, Abu Road in Rajasthan. 7.1.1.5 The R&D project sanctioned to IIT Delhi on development and evaluation of spectrally selective coatings for solar energy utilization was reviewed through an expert committee. A characterization facility for measurement of emmissivity and solar absorptance of selective surfaces has been developed under the project for use by industry and researchers. In addition, a selective coating for radiative cooling, developed under the project, showed potential for commercialization. 7.1.1.6 Regional Research Laboratory, Bhubaneshwar has submitted the completion report of the R&D project entitled "Solar Box 7.1 A large area solar dish has been developed to provide process heat for milk pasteurization at a dairy of Maharashtra Rajya Sahakari Dugdh Mahasangh Maryadit (MRSDMM), Maharashtra under a R&D project sponsored by MNES to IIT Bombay jointly with M/ s. Clique Developments Pvt. Ltd. (CDPL), Mumbai. The solar dish has been installed and commissioned. The technical specifications of the solar system are Aperture Area 160 m2 Reflector area 123 m2 Thermal power (annual average) 50-70 kWth Annual operating hours 3200-3350 hours/ year Annual fuel savings (Furnace oil) 16 to 24 kilo litre/ year Operating wind speed up to 54 kmph Survival wind speed up to 140 kmph Aerial clear space required for the dish 25 m x 20 m x 18 m height Clear area required on ground / roof 3 m x 3 m Tracking power 500 W Large Area Solar Dish at Milk Dairy at Latur, Maharashtra
