The composition of the solar panel and the functions of each part


A solar cell, also known as "solar chip" or "photovoltaic cell", is an optoelectronic semiconductor sheet that uses sunlight to generate electricity directly. So what are the main components of solar panels? This article mainly introduces what the solar panel is mainly composed of and its various functions.



(1) Tempered glass: Its function is to protect the main body of power generation (such as battery), and the selection of light transmission is required:The transmittance must be high (generally more than 91%); Ultra-white tempering treatment.


(2) EVA: It is used to bond and fix the tempered glass and the main body of power generation (cells). The quality of the transparent EVA material directly affects the life of the module. The EVA exposed to the air is easy to age and turn yellow, thus affecting the light transmission of the module. In addition to the quality of EVA itself, the lamination process of module manufacturers is also very influential, such as substandard EVA adhesiveness, insufficient bonding strength between EVA and tempered glass and backplane, all of which will cause EVA Premature aging affects component life.


(3) Cells: The main function is to generate electricity. The mainstream in the power generation market is crystalline silicon solar cells and thin-film solar cells, both of which have their own advantages and disadvantages.


Crystal silicon solar cells have relatively low equipment cost, but high consumption and cell cost, but also high photoelectric conversion efficiency, which is more suitable for power generation in outdoor sunlight.


Thin-film solar cells have relatively high equipment costs, but low consumption and battery costs, but the photoelectric conversion efficiency is more than half that of crystalline silicon cells, but the low-light effect is very good, and it can also generate electricity under ordinary lights, such as calculators on the solar cell.


(4) Backplane: function, sealing, insulating, waterproof. Generally, TPT, TPE and other materials must be resistant to aging. Most component manufacturers have a 25-year warranty. Tempered glass and aluminum alloys are generally no problem. The key is whether the backplane and silicone can meet the requirements.


(5) Aluminum alloy: Protect the laminate and play a certain role in sealing and supporting.


(6) Junction box: It protects the entire power generation system and acts as a current transfer station. If the component is short-circuited, the junction box will automatically disconnect the short-circuit battery string to prevent the entire system from being burned. The most important thing in the junction box is the selection of diodes. Different types of cells have different corresponding diodes.


(7) Silicone: for sealing, used to seal the junction between the component and the aluminum alloy frame, the component and the junction box. Some companies use double-sided tape and foam to replace the silicone. Silicone is commonly used in China. The process is simple, convenient, and easy to operate. And the cost is low.


What you need to know about solar panel manufacturers


What is a solar panel? A solar panel refers to a device that directly converts solar energy into electrical energy by using the photovoltaic effect of semiconductor materials under light conditions. It is the most direct way to use solar energy, and most of the material is silicon. Electricity can be generated anywhere there is sunshine, so solar PV is suitable for everything from large power stations to small portable chargers.


Classification of solar panels


Solar panels are generally divided into two types: crystalline silicon solar cells and thin film solar cells. Crystalline silicon solar cells are made from silicon, a material found in sand. Thin-film solar cells are made from a number of different materials, including cadmium telluride, amorphous silicon, and copper indium gallium selenide.


Solar panels are classified according to their power output. Power output is measured in watts and is a way of quantifying the amount of electricity a solar panel can produce. Solar panels range in power from 10 watts to 400 watts. The classification of solar panels is important because it helps consumers choose the right product according to their needs.


Solar panels are classified according to their power output. The most common type is crystalline silicon solar panels made from silicon crystals. They are either monocrystalline or polycrystalline. Monocrystalline panels are more efficient, but also more expensive. Polycrystalline panels are less efficient, but also less expensive.


Solar full panel and half panel


Solar photovoltaic (PV) panels are devices that convert sunlight into electricity. They are often installed on rooftops and can be used to power everything from homes to businesses. Solar PV panels come in a variety of sizes, but the most common size is about 1 square meter. There are two types of solar PV panels: monocrystalline and polycrystalline. Monocrystalline panels are made of a single crystal of silicon, while polycrystalline panels are made of multiple crystals.


Solar panels are devices that convert sunlight into electricity. They are called "solar" because the sun is the source of light energy that drives the process. Solar panels can be used to power everything from small electronic devices to entire homes and businesses.


There are two types of solar panels: full panel and half panel. Full panel solar panels are larger and more powerful than half panel solar panels. Half panel solar panels are less expensive and easier to install, but they produce less electricity.


A solar panel is a device used to capture energy from the sun and convert it into electricity or heat. Solar panels are most commonly used for solar power, but they can also be used to heat water or air. There are two types of solar panels: photovoltaic (PV) panels, which convert sunlight into electricity, and thermal panels, which capture the sun's heat to generate hot water or air. PV panels are made up of an array of solar cells, each of which converts sunlight into electricity. Thermal panels use the sun's heat to generate hot water or air.

The solar panel market is driven by factors such as the increasing demand for renewable energy and the declining cost of solar panels. However, the market faces challenges such as the high initial investment cost and the intermittency of solar power.


How can solar panels improve their service life?


Solar panels are designed to withstand harsh weather conditions and last for many years. However, like any other type of equipment, they require occasional maintenance and repairs. Proper care can extend the service life of your solar panels and help them operate at peak efficiency. Here are a few tips on how to care for your solar panels:


1. Keep them clean - Dirt, dust, and bird droppings can all reduce the amount of sunlight that reaches the solar cells, reducing their output. Regularly cleaning your panels will help keep them operating at peak efficiency.


2. Inspect them regularly - Look for signs of damage such as cracked or chipped cells, loose connections, and damaged mounting hardware. If you notice any problems, contact a qualified solar panel technician for repair or replacement.


3. Protect them from shading - Shade from trees, buildings, or other objects can reduce the output of solar panels by blocking some of the sunlight that would otherwise reach the cells. Trimming trees and
