Abstract
Solar water heating package for light commercial use was developed. We properly designed the system for huge and endless hot water demand. For such users, tank volume could be smaller, so we adopted 200-liter tank. And solar collector can be connected up to16m^2, four tunes as large as domestic use. Due to the system is packaged, it could be reduced size. In September 2009, we have installed the solar water heating package for light commercial at a casual restaurant and tested the system performance.
