Abstract	Nowadays the field of applied mechanical systems opens new horizons for the use of orientation mechanisms. The opportunity to use mechanisms with a “sustainable purpose” leads to new approaches in the development of renewable energy systems design. In literature review many authors says the evaluation of the existing products shows that the tracking mechanisms for solar energy conversion systems may improve the efficiency of the solar energy conversion systems up to 30% to 50%. Applications of solar energy for domestic and industrial heating purposes are becoming very popular. However the effectiveness of presently used fixed flat plate collectors, photovoltaic panels and parabolic collector are low due to the moving nature of the energy source. This paper presents researches in the field of increasing the efficiency of the solar energy conversion by using tracking systems with flat plate collector of solar water heating system with the aim to change the position of the solar collector/solar panels correlated to the sun position for maximizing the use of beam radiation by real time digital tracking method. H.V. Byregowda et.al. optimized the interaction between the mechatronic system components by integrating the analog electronic system by using a 555 timer in the mechanical model by designing a single axis low cost tracking system of experimental model in order to reduce cost and show improvement in efficiency of tracking systems before beginning with the virtual prototype level. The work done by these authors was at chickballapur location in BGS R&D centre, SJCIT College. The result Obtained in their research work is that, the thermal efficiency was increased by 21% with tracking of manual method and by 24% with analog method of automatic tracking system. In the present work, a new method of tracking system has been developed electronically with solar water heating systems used in homes for water heating and Power utilization as multiple purpose domestic applications by adding real time clock (RTC) digital, microcontroller, DC motor, Electronics circuit board, batteries and photovoltaic panels along with water tank, flat plate collector which are existing at present in homes only for water heating applications. The results obtained in present work of digital tracking system the thermal efficiency of experimental working model of flat plate collector shows 30% increase when compared with tracking system and non tracking system.
