Abstract

In order to verify and take measures against a variety of troubles which cannot be predicted in a well-controlled laboratory, it is necessary that solar system should be experimented in an actual situation during a long period. Through this experiment it can be also understood how the load pattern and operational conditions expected in a design process become different to those in the actual running, which can be applied to a new system design. We installed 6 kW solar hot water heating system with a shower facility and operated during 7 months. As a result, average 8.3 persons took a shower a day； solar fraction is 71％ and total collector efficiency is 40％ during the periods from March to September. We confirmed several troubles encountered in the actual situation and considered practical center-measures.
