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-contac...

How to Make a Custom Solar Panel?

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 cert...

In the face of the epidemic sweeping the world, the problem of “two-level differentiation” is in front of the photovoltaic people. SMEs are struggling in a crisis-ridden environment and seeking hope for life, but for leading companies, it is still difficult to stop their pace of active expansion. The leading domestic solar cell manufacturers are not afraid of the impact of the epidemic and are actively expanding production. Custom Solar Panel  for Solar Powered LED Lighting Recently, Tongwei issued a fixed increase plan, which will raise no more than 6 billion yuan of funds, and it is expected that 4.2 billion will be invested in Meishan Phase II (7.5GW) and Jintang Phase I (7.5GW) high-efficiency solar cell projects. In addition to Tongwei, LONGi has announced a total expansion of 10GW of monocrystalline solar cells, AiXu expanded by 5.9GW, Jingao expanded by 10GW, and Jinko expanded by 10GW. It is expected that PERC solar cell expansion will reach 30GW this year , The co...
