How to measure the power of polycrystalline silicon solar panels?
The solar simulator is an instrument that simulates the spectrum and irradiation of solar light. It can be used to test the weather resistance and photostability of photosensitive materials, coatings and fibers, as well as to simulate solar radiation. .Evaluate the protective effect of sunglasses, parasols,sunscreen, etc. in the plant growing environment. It can also be used for solar cell testing, photocatalysis, light resistance and sun protection experiments of materials such as cosmetics and coatings, as well as photobiological inspection and testing.
In terms of solar protection effectiveness, the solar simulator can simulate solar radiation under different time and climate conditions to overcome the disadvantages of natural solar radiation affected by weather and climate, and the Total irradiance cannot be adjusted. Therefore, it can help researchers evaluate the sun protection effectiveness of different sun protection products and study the impact of different factors on sun protection effectiveness.
There is no specific optimal wavelength for tanning, because different wavelengths of lightLight have different effects on the human body.
1. Infrared ray (wavelength greater than 760 nanometers): It can dilate blood vessels, improve local blood circulation and promote human metabolism.
2. Visible light (wavelength 400-760 nanometers): It can promote human metabolism, regulate nerve function, and help maintain skin health.
3. Ultraviolet rays (wavelength 180-400 nanometers): They can promote calcium absorption, improve skin resistance, and have sterilizing and anti-inflammatory effects.
Taken together, infrared rays and visible rays mainly help to promote blood circulation and metabolism of the human body, while ultraviolet rays mainly help to promote calcium absorption and skin health. skin. Therefore, when sunbathing, you can choose the dappropriate urea and intensity of light exposure based on your personal needs and preferences. However, it should be noted that long-term exposure to strong sunlight can cause skin damage. You must therefore take care to protect the skin when sunbathing and avoid overexposure.
In short, the application of solar simulators to the effectiveness of sun protection can help researchers better understand the performance and use effects of sun protection products, and support the development of more effective sun protection products.
What are the test items for solar PV modules?
You cannot use your method to determine whether a product is substandard. Since standard tests are different from yours, even though standard tests cannot represent reality, unifying standards will helpto unify the different products.
First of all, the power given by the manufacturer is based on solar mode. Measured under the light source of the simulator, the basic requirement is that the simulator reaches 1000w/m2;
p>Second, the light source and the battery panel are illuminated vertically.
Later use IV curve meter to detect open circuit voltage, short circuit current, maximum power, optimum power, luminous efficiency, fill factor, etc. .
Your experience cannot be estimated simply. A transitory result of your time, this result may be different from the evaluated result:
1. The intensity of the light source is certainly not sufficient 2. Non-vertical lighting. multimeter, and the accuracy is not good.
In short, your experiment cannot prove that there is a problem with the battery board, but just reflects the capacity of proenergy reduction your battery can have at that time
1. There are many test items, I will focus on them. The current international standard for test items required for photovoltaic modules at the power plant site is also IEC62446. similar guidelines and specifications.
2. The key points are insulation resistance, grounding continuity, IV characteristics, open circuit voltage, short circuit current, infrared or EL testing, wind speed irradiation and other environmental tests.
