Abstract

After Industrial Revolution, energy has been recognized as an important factor which enhances the motive power for industry in the industrial society. However recently the excessive consumption of energy pursuant to the rapid expansion of industry created serious problems of the exhaustion of fossil fuels as well as unusual change in the weather due to the mass discharge of carbon dioxide. Especially the changes in weather created irreversible confusion to global ecological system and together with the confusion it became clear that whole fundamentals of current civilization of mankind will be shaken from the bottom. Recently people came to think that it is urgently required to explore the alternatives for the energy system based on current fossil energy which created the energy problem we encountered. After entering into the United Nations Framework Convention on Climate Change through the Global Environment Forum held in Rio de Janeiro of Brazil in 1992, the consciousness that the development should be done in the sustainable pattern in harmony with the environmental preservation has been closed up as an issue. We can say that after all these proposal will boil down to the development of New & Renewable energy. The method of solving the problem of disequilibrium between such energy supply system and ecology system is to establish small scale, decentralized and labor-intensive energy supply system. Under such system we can make ecological equilibrium again. The most suitable source of energy for this required change is solar energy. The advantages of solar energy are that it is renewable, infinite supplied and environmentally safe energy source, and the method of energy supply is in small scale and is decentralized. However, solar energy related products have the problems such as the limitation for installation, problems in maintenance and insufficient reliability, which have been the barrier to consumers to satisfy the purchase need for solar heat related products. In order to enhance the performance and reliability of solar energy related products and to expand the supply of the products, it is judged that the introduction of a certification system which will enable to limit the supply of the products with higher quality above certain level should be preceded at this point of time. However, as most solar heat related manufacturers are small in size and have insufficient facilities and manpower, it is not only difficult to develop products but also they have to go through inefficient procedures in terms of cost and time because in general newly developed products are required to go through many trial and errors up until new products can be commercialized. In this regard, in order to support the solar energy related companies, the necessity for various technical information required for the commercialization of new products such as various performance test necessary for the certification of solar energy system, standardization for facilities and products, performance evaluation method and the measurement of performance is suggested. The purpose of this paper is to design the monitoring system for positive tests of system linked 3kW solar light power generation system for household supplies and household hot water system using solar heat out of various solar energy systems, to establish an analysis and monitoring system for performance maintenance and operation technique, and to configure the centralized detection network by utilizing remote monitoring system. This research also aims at conducting monitoring for operation and performance evaluation in relation to database establishment and analytical evaluation and at describing the method of enhancing the reliability of solar energy system through the development of performance evaluation program. Furthermore this research will perform thermodynamic analysis through the application of infrared ray thermal imaging camera and will discuss about the applicability of solar energy system and other fields as well. The researcher hope that this research serves the cornerstone from the development process of solar energy system to its selection process and supply projects
