Solar modules have high photoelectric conversion efficiency and high reliability. The Solar module has advanced diffusion technology, and the Solar module ensures the uniformity of conversion efficiency across the chip. Solar modules ensure good electrical conductivity, reliable adhesion, and good electrode solderability. The high-precision screen-printed patterns and high flatness of Solar modules make the battery easy to automatically weld and laser cut. So what is a solar module? Let's take a look together below.
Here is the content list:
Component definition
Monocrystalline Solar modules
Solar modules are composed of high-efficiency monocrystalline/polycrystalline solar cells, low-iron ultra-white suede tempered glass, packaging materials (EVA, POE, etc.), functional backplanes, interconnection bars, bus bars, junction boxes, and aluminum alloy frames. The service life of Solar modules can reach 15-25 years.
A single Solar module cannot be used directly as a power source. As the Solar module is used as a power source, several single Solar modules must be connected in series and parallel, and tightly sealed in the Solar module. Solar modules (also called solar panels, photovoltaic modules) are the core components of solar power generation systems, and they are also the most important part of solar power generation systems. The role of solar components is to convert solar energy into electrical energy, or send it to storage batteries, or drive loads to work. The quality and cost of Solar modules will directly determine the quality and cost of solar systems.
The energy converter of solar photovoltaic power generation is the solar cell (Solar Cell), also known as the Solar module photovoltaic cell. The principle of Solar module battery power generation is the photovoltaic effect (Photovoltaic Effect). When sunlight shines on the solar cell, the Solar module cell absorbs light energy and generates photo-generated electron-hole pairs. Under the action of the built-in electric field of the battery, the photogenerated electrons and holes are separated, and the accumulation of charges of opposite signs occurs at both ends of the battery, which generates a "photovoltaic voltage", which is the "photovoltaic effect". If the electrodes are drawn on both sides of the built-in electric field and the load is connected, the load will have a "photo-generated current" flowing through it, thereby obtaining power output. In this way, the light energy of the sun directly becomes usable electrical energy.
Under the same temperature, the influence of light intensity on Solar modules: the greater the light intensity, the greater the open-circuit voltage and short-circuit current of the solar module, and the greater the maximum output power. At the same time, it can be seen that the open-circuit voltage changes less than the radiation intensity The short-circuit current changes significantly with the radiation intensity.
Under the same light intensity, the effect of temperature on Solar modules: when the temperature of the Solar module increases, the output open-circuit voltage of the Solar module decreases significantly with the temperature, and the short-circuit current of the Solar module increases slightly. The general trend is the maximum output of the Solar module The power becomes smaller.
