Once someone have done the experiment. In mid-july, temperatures of up to 40 ℃, Shanghai people braved the heat did a series of experimental data. ( Special note: the data record type adopts the infrared thermometer, China solar energy network, solar energy, due to surface color object to be tested, could lead to a temperature slightly deviation, but the basic reflect the surface temperature of object to be tested, solar panels, can be for reference. )
under the high temperature of 40 ℃, at 12 noon, the roof temperature up to 68. 5℃。 Only 57 measuring surface temperature of the photovoltaic modules. 5 ℃, lower than the roof temperature of 11 ℃. Photovoltaic modules back temperature is 63 ℃, solar energy, but still lower than the roof temperature 5. 5℃。
