    摘要: Techniques for analyzing performance of solar panels and/or cells are provided. In one aspect, a method for analyzing an infrared thermal image taken using an infrared camera is provided. The method includes the following steps. The infrared thermal image is converted to temperature data. Individual elements are isolated in the infrared thermal image. The temperature data for each isolated element is tabulated. A performance status of each isolated element is determined based on the tabulated temperature data. The individual elements can include solar panels and/or solar cells. In another aspect, an infrared diagnostic system is provided. The infrared diagnostic system includes an infrared camera which can be remotely positioned relative to one or more elements to be imaged; and a computer configured to receive thermal images from the infrared camera, via a communication link, and analyze the thermal images.
