This paper summarizes the results of author's studies on solar energy resource utilization. One is the development of a micro solar power generation which was combined with micro wind power generation at urban area. The other is the solar thermal utilization by an absorption heat pump for air conditioning. Daily fluctuations of energy supply in Osaka city both by electricity and by town gas were presented precisely in order to understand the energy consumption of urban area. Then, field test results about a micro hybrid power generation system were presented at urban coastal area where there is few wind power resource. Lastly, the performance of a solar-assisted absorption chiller heater of 352 kW refrigeration capacity has been introduced through a long series of proof examination of 17 months.
