PURPOSE: A sensorless solar tracking method for monitoring and cooling a sunlight panel and a sunlight panel assembly used in the same are provided to improve cooling efficiency by a hole for the flow of air and to monitor each panel. CONSTITUTION: A sensorless solar tracking method for monitoring and cooling a sunlight panel comprises following steps. User parameters are set up and stored(S1). Each voltage(V1~V9)(or current) of 9 panels of a solar energy panel assembly is read(S2). Whether the sum total of each voltage of the 9 panels of the solar energy panel assembly is higher than panel minimum power(VOMIN) is determined(S3). If the sum total of each voltage of the 9 panels of the solar energy panel assembly is higher than panel minimum power, the operation of each panel is checked(S4). Whether the value of(V1+V4+V7)-(V3+V6+V9) is within right and left allowable voltage difference(VLR) is determined(S5). Whether the value of(V1+V4+V7)-(V3+V6+V9) is within top and bottom allowable voltage difference(VUD) is determined(S6). The performance of each panel is checked(S7). |
