Solar Photovoltaic<\/a>Welding strip is the mainstream of everySolar Cells<\/a>An important component of the panel that interconnects the solar cells and provides connections to the junction box.<\/p>\n

Photovoltaic ribbon is a key component of solar panels and an important factor in improving the efficiency and durability of solar panels. Only when high-quality photovoltaic ribbons are correctly installed on solar panels can the high efficiency and durability of solar panels be achieved. The quality of photovoltaic ribbons and their welding to solar cells are important factors in ensuring the efficiency and durability of solar panels.<\/p>\n

The resistance of the soldering ribbon is mainly determined by the size of the soldering ribbon itself and the material of the copper substrate. The composition of the surface tin coating will not have a significant effect on the resistance of the soldering ribbon. Increasing the width or thickness of the soldering ribbon can reduce the resistance of the soldering ribbon. This improvement can play the same role for both traditional soldering methods and new low-temperature connection methods such as conductive silver glue or conductive ribbon connection. However, a soldering ribbon wider than the width of the front electrode will block the incident light and cause current loss.<\/p>\n

The part of the solar cell covered by the solder ribbon cannot absorb sunlight. Some solder ribbon companies have introducedReflective welding tape<\/a>The front of the solder ribbon is a silver-plated and rolled longitudinal groove structure, which can reflect the light incident on the solder ribbon to the inner surface of the glass layer of the component at a certain angle, and then project it to the surface of the battery after total reflection at the glass-air interface. The captured light can enable the component to generate additional power, which can theoretically increase the efficiency of the component by about 2%.<\/p>\n

The performance indicators of photovoltaic ribbons are all important. The type of copper and its purity determine the conductivity of the material and the maximum flexibility that can be achieved with the ribbon. The flux composition, its cover thickness and cover composition affect the quality of the solder joint and thus the durability of the solar panel.<\/p>\n

High elongation of the PV ribbon is very important to prevent failure of the solder joints between the bus ribbon and the interconnector bar, which can be caused by elongation\/tension generated by oscillating temperature changes during the operation of the solar panel. The continuous and sometimes extremely strong temperature oscillations during the service life of the solar panel on a daily basis put the solder joints to the test during the service life of the solar panel (25 years on average).<\/p>","protected":false},"excerpt":{"rendered":"
