What is photovoltaic performance testing and what tools are used to detect photovoltaic function tes

Solar simulator is a device used to simulate sunlight, in the photovoltaic field, coupled with electronic load, data acquisition and calculation equipment, can be used to test the electrical performance of photovoltaic devices (including solar cells, solar cell modules, etc.), such as pmax, imax, vmax, isc, voc, ff, eff, rs, rsh and i-v curves.

For PV performance testing, there are two types of commercial solar simulators available, one is the steady-state simulator (e.g., filtered xenon lamp, two-color filtered tungsten lamp-ELH lamp, or modified mercury lamp), which is suitable for testing single cells and small size modules. The other type is pulse simulators, which consist of one or two long-arc xenon lamps, which are better adapted to the testing of large-scale components due to their good radiometric uniformity over a large area. Another advantage of this type of simulator is that the heat input of the battery under test is negligible, so that the test point is consistent with the ambient test temperature, which can be easily and accurately measured.

Photovoltaic performance refers to the photoelectric conversion performance.

It is the illumination current and voltage generated by electronic devices or products after they are exposed to a certain amount of light.

If you have a dedicated PV characteristic tester i-V checker, please refer to the link below if you do not need an instrument.

Hello dear, I am Xiao Yang, the answer to the app ask a question platform. I understand your problem. A variety of tools are generally used for photovoltaic function testing and testing, including battery testers, thermocouples, photoelectric meters, thermocouples, thermocouples, etc.

A battery tester can measure the voltage, current, power, and temperature of a battery in order to understand the performance of the battery. Thermocouples can measure the temperature of solar panels in order to understand the performance of solar panels. A photomegagalvanometer can measure the photocurrent of a solar panel in order to understand the performance of the solar panel.

Thermocouples can measure the temperature of solar panels in order to understand the performance of solar holding panels. In addition, electronic device testers, insulation testers, resistance testers, etc., can also be used to test the performance of solar pion panels.

Summary. In the roof test, first connect the red at one end of the cable to the positive pole of the power supply, and the blue to connect the negative pole of the power supply. Then connect the MC4 plug at the other end with the MC4 plug of the assembly.

Dial the DC gear at the same time as the power selector switch and input mode selector to start the power supply. If you need external power supply, you need to turn the power selection switch and input mode selection to the AC gear at the same time. Finally press the red output selection button.

Hello, dear, I'm glad to have your question, what tool is used to detect the photovoltaic function test, as follows: insert the SD card into the camera mounting card slot, and insert the battery into the camera battery compartment. The trace cover connects the EL camera with the external WiFi controller through the cable.

Click the white switch button on the side of the controller to turn on the Yanmin controller.

Connect the bottom of the camera with the connecting block on the bracket and tighten the screws. By connecting the imaging system to the bracket system, the 3 feet of the bracket can be lengthened by means of an annular thread lock, and the camera angle can be adjusted by a manual Richard gimbal on the bracket. Place the connected system in front of the module to be measured, and the distance between the slag machine and the module is within the range of meters, so that the whole module can be obtained.

During the roof test, first connect the red at one end of the cable with the positive beam of the power supply, and the blue with the negative pole of the power supply. Then connect the MC4 plug on the other end to the MC4 plug of the assembly. Dial the DC gear at the same time as the power selector switch and input mode selector to start the power supply.

DC is the internal power supply of the lithium battery) If the rubber fibrillation needs external power supply, you need to dial the power selection switch and input mode selection to the AC gear at the same time. Finally press the red output selection button.

Tests generally include:

1) Lightning protection and grounding measures.

2) The strength and corrosion resistance of the stent material.

3) Electrical insulation.

4) Power quality assessment.

5) Functional test of the inverter.

6) Off-grid also includes the functional test of the controller and the charging and discharging characteristics of the battery, (7) Off-grid includes the test of grid-connected control and protection measures.

The test items are mainly based on IEC62105, and the content mainly includes:

1. I-V performance test of the system.

2. Weather resistance test of the system.

You can refer to some of them in his blog.

The full name is photogenerated voltaic effect: it means that light can be converted into electricity. Contrary to the principle of light-emitting diodes, LEDs generate light when they are electrified, while the PN section of a battery panel generates electricity when it is light.

Performance is generally said to be the conversion efficiency of photovoltaic modules. Because the solar radiation energy per square meter is certain, if the conversion efficiency is high, the more electrical energy is obtained.

At present, the conversion efficiency of polysilicon is about 16%, monocrystalline silicon is about 19%, and amorphous silicon is generally between 5-9%.

ENN PV is currently the highest amorphous silicon, which can reach more than 9% in the future. It is suitable for photovoltaic curtain wall, BIPV building integration, photovoltaic power station can be applied to the publicity of billboards, light boxes, bus stations and other fields due to foreign good looks.

Photovoltaic performance refers to the photoelectric conversion performance, that is, the illumination current and voltage generated by electronic devices or products after being exposed to a certain amount of light.

IV or PV performance. It's the relationship between power and voltage.

As an important part of photovoltaic technology, photovoltaic testing and quality certification are increasingly of concern for photovoltaic technology developers.

Photovoltaic testing technology is mainly based on the requirements of IEC, UL and various national industry standards to test the performance of specific photovoltaic products to prove that they meet the performance and safety requirements. The main test standards are IEC 61215 for crystalline silicon, IEC 61646 for thin-film modules, IEC 62108 for concentrating photovoltaics, UL 1703 for the United States, and GB 9535 for China. The main test items include electrical performance test, environmental aging test, mechanical performance test, fire protection and other safety tests.

China Photovoltaic Test Network has a special section for data inquiry, test analysis and test methods in the field of testing and certification of photovoltaic products and raw materials.
