| 积雪的清除已成为当今光伏板研究关注的重点。本研究基于光伏电池、传热学和力学的相关原理，将环境温度设为单一变量，研究不同环境温度（-3、-4.5、-6、-7.5、-9 ℃）对光伏板自加热除雪性能的影响。实验研究表明：当积雪厚度为6 cm、积雪密度为420 kg/m3、加热功率为230W/m2、光伏板倾角为18°时，环境温度每升高1 ℃，光伏板上积雪待融时间缩短约6 min，融化时间缩短约11 min，除雪总时间缩短约17 min，除雪耗电量减少约380. 9 kJ，除雪总时间受环境温度的影响很大。 |

| Abstract: |
| The removal of snow on photovoltaic (PV) panels has become an important issue in current research on PV panels. In this study, the influence of ambient temperature on the snow removal effect ofself-heating PV panels was studied using the basic principles of PV cells, heat transfer and mechanics. When the snow thickness was 6 cm, heating power was 230 W/m2, snow density was 420 kg/m3, and the inclination angle was 18°, the pre-melting time was shortened by approximately 6 min, the melting time was reduced by approximately 11 min, the total snow removal time was shortened by approximately 17 min, and the power consumption of snow removal was reduced by approximately 380.9 kJ for every 1 °C increase in ambient temperature. Thus, the total snow removal time was greatly affected by ambient air temperature. |
