Abstract

At present PV modules are fire-resistant for about 30 min This study proposes the design of fire-resistant PV modules In this study the fire and heat performance of PV modules is evaluated using the CNS 12514-1 testing method In the test of PV module with insulation materials there are 3 kinds of fire-resistant methods of polysilicon PV modules and a fire-resistant method of CIGS thin-film PV module Polysilicon PV modules with a calcium silicate board (ITRI) a phenova insulation board (ITRI) a gypsum board(ITRI) as exposed surfaces respectively were tested There were wire holes on the back board of the PV modules in the three designs The holes degraded fire resistance And in the fire-resistance test of CIGS thin-film PV module with a calcium silicate board as exposed surfaces The result shows no flame sprung up in the 2 h of testing Although the design had better integrity the insulation of the PV module was failure Moreover CIGS thin-film PV module with water film was placed on the exposed surface in 2 h of testing After adjusting the water film flow thickness and coverage of system there is no flame sprung up in the 2 h of testing PV module with water film had 2 h of fire and heat resistance PV modules with and without a water jacket were tested The effect of water circulation in the water jacket on the temperature change of the PV module was investigated A PV module with a water jacket can reduce the heat of the PV module caused by sunshine and power generation of building In the full-scale heating furnace test PV modules with an aluminum calcium silicate and gypsum boards respectively were tested Wire holes in the PV modules on the exposed surface allowed flames to pass through degrading fire performance Before the PV module vertical fire spread test the output voltage and current of the PV module were set to 3 V and 0 A respectively When the oil pan ignited the PV module was affected by the brightness of the flame and the radiation and the output voltage and current increased The heat of the flame led to the glass and interlayer compounds in the PV module to break and peel sharply reducing the output voltage and current The output voltage and current of the PV module decreased to 0 V and 0 A respectively For the fire spread test of the PV module used in curtain wall We built the apparatus for testing the fire-resistant performance of the exterior curtain wall in ASTM E2307-15b which was selected in the national regulations to carry out the standard test for the exterior PV module curtain wall or other kinds of curtain wall In the first-time calibration test the error of temperature profile may be due to the fuel not being directly indicated in ATSM E2307-15b but that of NFPA 285 being natural gas (NG) The fuel used for this test is LPG not NG Because the two heating values are significantly different a conversion is needed and the gas flow must be adjusted before next calibration test
