人类社会正面临着能源资源短缺、生态环境恶化的双重压力;全球气候变暖已成为全世界共同关注的热点课题。太阳能作为—种清洁、可再生的能源,已经受到世界各国的重视。

Human society is facing the dual pressure of energy shortage and ecological environment deterioration; global warming has become a hot topic of common concern in the world. As a kind of clean and renewable energy, solar energy has been paid attention to by all countries in the world.

太阳能组件在短接情况下,由于单片太阳能电池电阻过大,导致局部出现”热斑”效应。应用红外热像仪进行检测,能够有效的提高产品质量,节约成本。使用热像仪进行太阳能电池板检查有着若干优势。异常现象能够清楚地显示在清晰的热图像上,并且与其他大部分方法不同的是,热像仪能够用于对已经安装好的太阳能电池板在运行期间进行检查。最后,热像仪还可在短时间内检查大片区域。

When the solar module is short circuited, the resistance of the single solar cell is too high, resulting in local "hot spot" effect. The application of infrared thermal imager can effectively improve product quality and save cost. There are several advantages in using thermal imagers to inspect solar panels. Abnormal phenomena can be clearly displayed on a clear thermal image, and unlike most other methods, the thermal imager can be used to check the installed solar panels during operation. Finally, the thermal imager can also check large areas in a short time.

红外热像仪同样也能检查太阳能电池板的程序,为了在检查区域中的太阳能电池时获得足够的热对比度,需要500 W/m2或更高的太阳辐照度。但为了获得最大的效果,建议太阳辐射为700 W!m2。太阳辐照度以kW/m2为单位描述入射在表面上的瞬时功率,可用总辐射表(对于整体太阳辐照度)或太阳辐射仪(对于直接太阳辐照度)进行测量。这在很大程度上取决于位置和当地天气。较低的外部温度也可能增加热对比度。

The infrared thermal imager can also check the procedure of solar panels. In order to obtain sufficient thermal contrast when checking solar cells in the area, solar irradiance of 500 W / m2 or higher is required. However, in order to achieve the maximum effect, the solar radiation of 700 w! M2 is recommended. Solar irradiance describes the instantaneous power incident on the surface in kW / m2, which can be measured by a total radiometer (for global solar irradiance) or a solar radiometer (for direct solar irradiance). It depends largely on the location and the local weather. Lower external temperatures may also increase thermal contrast.
