JDSOLAR photovoltaic module main technical indicators

I. Photovoltaic module photoelectric conversion efficiency
(I) Definition of photoelectric conversion efficiency
Photovoltaic module photoelectric conversion efficiency refers to the ratio of the maximum output power of a photovoltaic module to the solar power of the module under standard test conditions (AM1.5, module temperature of 25 ° C, and irradiance of 1000W / m2).
(2) Determination of photoelectric conversion efficiency
The photovoltaic module's photoelectric conversion efficiency is tested by a third-party testing laboratory that has passed the National Qualification Accreditation (CMA) in accordance with the method specified in the GB / T 6495.1 standard. If necessary, the temperature and irradiance can be corrected according to the GB / T 6495.4 standard.
The calculation formula is:
 (Where the module area is the entire area of the photovoltaic module including the frame)
Mass production of photovoltaic modules must be certified by a certification body approved by the State Accreditation Administration, and the deviation between the actual power and the nominal power of each individual module product must not be higher than 2%. The corresponding peak power technical indicators of the photoelectric conversion efficiency of several commonly used standard crystalline silicon modules are as follows:
Material Type Cell
Size (mm) Cell
Quantity 15.5% conversion efficiency corresponds to module peak power (Wp) 16% conversion efficiency corresponds to module peak power (Wp) 16.5% conversion efficiency corresponds to module peak power (Wp) 17% conversion efficiency corresponds to module peak power (Wp)
Polysilicon 156 * 156 60 255/270 /
156 * 156 72 305/325 /
Monocrystalline silicon 156 * 156 60/260/275
156 * 156 72/315/330
For non-standard crystalline silicon photovoltaic modules (such as dual-glass modules), the conversion efficiency may not be calculated according to the above formula, but the efficiency of the cells used should be consistent with the requirements for the photoelectric conversion efficiency of the cells in the Ministry of Industry and Information Technology's "Standard Conditions for Photovoltaic Manufacturing Industry" And must be certified by a certification body approved by the State Accreditation Administration.
For concentrating photovoltaic modules, the standard test conditions are AM1.5, the module temperature is 25 ° C, the irradiance is 1000W / m2, and the module area is the corresponding lens area.
Second, the attenuation rate of photovoltaic modules
(I) Definition of photovoltaic module attenuation rate
Photovoltaic module attenuation rate refers to the ratio of the maximum output power under standard test conditions (AM1.5, module temperature 25 ° C, irradiance 1000W / m2) to the initial maximum output power after commissioning after a period of operation.
(2) Determination of the attenuation rate of photovoltaic modules
The determination of the attenuation rate of photovoltaic modules can adopt accelerated aging test methods, field comparison verification methods or other effective methods. The accelerated aging test method is to use an environmental test box to simulate the environmental conditions such as irradiance, temperature, and humidity during actual outdoor operation, and to double or tighten related parameters to achieve the purpose of accelerating the aging and attenuation of components in a short time. . After the accelerated aging test is completed, a power test is performed on the test module under standard test conditions, and the attenuation rate of the photovoltaic module's power generation performance is determined according to the attenuation rate formula.
The field comparison method is to take a sufficient number of component samples according to the installed capacity of the project from the date of component production and operation. After the initial maximum output power, it is installed in the same environment as other components produced in the same batch to run normally to generate electricity, and its maximum output power is measured again one year after the date of operation. The maximum output power before and after the comparison is compared, and the attenuation rate of the photovoltaic module's power generation performance is determined according to the calculation formula of the attenuation rate.
The calculation formula is:
