For the exhaustion of petrochemical energy in the whole world, the need to develop new & renewable energy has been growing. Scientists still do research to develop new & renewable energy, most of all, solar energy. Because a solar condenser mostly should be installed on a roof or floor, so it is greatly affected by wind. Nevertheless, the standard to install the solar condenser is not arranged. Therefore, we conducted a wind tunnel experiment (test) to investigate the differences of wind pressure that the solar condenser got according to angle variations and deduct the proper standard to install. In the experiment, it was used that solar array models of 5x3 and 3x5, and it was conducted by changing each angle to 30°, 35°, and 40°.
