To solve the problems of low detection efficiency, low accuracy, and difficulty of distributed hot spot detection, a hot spot detection method using a photovoltaic module based on the distributed fiber Bragg grating (FBG) sensor is proposed. The FBG sensor array was pasted on the surface of the photovoltaic panel, and the drift of the FBG reflected wavelength was demodulated by the tunable laser method, wavelength division multiplexing technology, and peak seeking algorithm. The experimental results show that the proposed method can detect the temperature of the photovoltaic panel in real time and can identify and locate the hot spot effect of the photovoltaic cell. Under the condition of no wind or light wind, the wave number and variation rule of photovoltaic module temperature value, environmental temperature value, and solar radiation power value were basically consistent. When the solar radiation power fluctuated, the fluctuation of hot spot cell temperature was greater than that of the normal photovoltaic cell. As the solar radiation power decreased to a certain value, the temperatures of all photovoltaic cells tended to be similar.<\/jats:p>","DOI":"10.3390\/s22134951","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T01:40:36Z","timestamp":1656639636000},"page":"4951","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Hot Spot Detection of Photovoltaic Module Based on Distributed Fiber Bragg Grating Sensor"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5765-9207","authenticated-orcid":false,"given":"Guoli","family":"Li","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Jinling Institute of Technology, Nanjing 211169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Jinling Institute of Technology, Nanjing 211169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Jinling Institute of Technology, Nanjing 211169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Wei","sequence":"additional","affiliation":[{"name":"Wuxi Brillouin Electronic Technology Co., Ltd., Wuxi 214131, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"935","DOI":"10.1016\/j.renene.2021.01.028","article-title":"Measurement and key influencing factors of the economic benefits for China\u2019s photovoltaic power generation: A LCOE-based hybrid model","volume":"169","author":"Wang","year":"2021","journal-title":"Renew.
