How to Connect Solar Cells?

图片
When we produce customized solar panels according to the specific needs of customers, we usually need to cut the solar cells into small pieces, and then connect the small pieces of solar cells in series or parallel as needed to form a solar cell string. Then, different numbers of solar cell strings are connected according to the required electrical performance to form a solar panel.   According to different types of solar cells and different production processes, there are usually two ways to connect solar cells.   For traditional crystalline silicon solar cells, in mass production, the connection method is usually through an automatic string welding machine. The positive electrode of one solar cell is connected to the negative electrode of the adjacent solar cell with a soldering ribbon to form a solar cell string. Using a string welding machine can not only greatly improve production efficiency and save labor costs, but also ensure product consistency.   For back-contact solar cells,

How to Make a Custom Solar Panel?

图片
A solar panel is a device that converts solar radiation into electrical energy through the photoelectric effect by absorbing sunlight.   Then, how to make a  custom solar panel ? Following are the several steps about how to make a solar panel. 1. Solar cell testing & cutting. Solar cells are checked and inspected to ensure no damaged or cracked cells. Then using laser cutting machine to cut the solar cells into small pieces in uniform size, depending on the wattage of a custom solar panel. 2. Solar cell soldering Using the solar cell stringer machine, solder the ribbons to the front and back surfaces of individual solar cells, and then solder the front side ribbons of a first solar cell to the back side ribbons of the neighboring solar cell to form solar cell strings wired in series.  3. Laminated laying After the solar cells are soldered and connected in series and passed the inspection, the solar cell strings, glass, EVA, and back sheets are laid according to a certain level, rea

What is an Amorphous Silicon Solar Cell? Amorphous Solar Panels Advantages and Disadvantages

图片
  Amorphous silicon solar cells are thin-film solar cells based on amorphous silicon compounds. According to different materials, current silicon solar cells can be divided into three categories: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells.                                                                          Indoor Solar Panels   Advantages of amorphous solar cells 1. Low production cost: Due to the low reaction temperature, it can be manufactured at a temperature of about 200 °C, so films can be deposited on glass, stainless steel plates, ceramic plates, and flexible plastic sheets, which are easy to produce in large areas and have low costs.   2. Short energy return period: Amorphous silicon solar cells with a conversion efficiency of 6% use about 1.9 kWh/W of electricity for production, and the time to return the above energy after generating electricity is only 1.5-2 years.   3. Suitable for mass

Evolution of Silicon Wafer Size

图片
Silicon wafers are divided into semiconductor wafers and photovoltaic wafers according to their uses. Photovoltaic silicon wafers can be single crystal silicon or polycrystalline silicon, and semiconductor silicon wafers can only be single crystal silicon. The biggest difference between the two is that the content and purity of silicon are different. The conversion efficiency of monocrystalline silicon is generally about 18.5%~25%, and the conversion efficiency of polycrystalline silicon wafer is about 17.3%. Correspondingly, monocrystalline silicon solar cells have higher photoelectric conversion efficiency than polycrystalline silicon solar cells.                                                                                        Over the years, the silicon  wafer size  has experienced a process from small to large. The increase in silicon wafer size and the continuous progress of photovoltaic technology have promoted the cost reduction and efficiency improvement of the entire pho

How to Choose a Small Solar Panel That is More Suitable for Your System?

图片
Stand-alone solar panels are widely used in various industries such as remote telemetry, security, monitoring, fence charger, gate opener, intelligent traffic, senor, IoT and aviation obstruction lights, especially with the improvement of solar cell conversion efficiency and the decrease in the cost per W of the solar panel will inevitably further expand the application range of custom shaped solar panels. How should we choose the solar panel suitable for our system?                                                                                       Small Solar Panels     1. If the product needs to be placed in harsh environments on the sea, desert, wetland, etc. for a long time, we recommend using glass solar panels. Because glass has the advantages of high light transmittance, hard texture and stable physical and chemical properties, it can well protect solar cells from being oxidized and crushed. However, the disadvantage of glass solar panels is that the unit weight is heavier th
