The module manufacturer LONGi is one of the world's leading producers of monocrystalline solar cells. Shortly after its founding in 2000, the company focused on monocrystalline silicon wafers. The goal: low electricity production costs for LONGi customers and the promotion of the monocrystalline module structure. With this strategy, the company today ranks first among mono ingot & wafer manufacturers for the new high-performance M6 cell formats. LONGi relies on innovative technologies and strict quality tests for its products. This makes the highly efficient LONGi modules extremely reliable and versatile.
Module technology Less power loss, more yield! This is because modules with Half-Cut technology consist of 120 small cells instead of 60 larger ones. By halving the cells, power losses are reduced and the efficiency of the modules is increased compared to modules without half-cut technology. This results in higher yields and makes the entire PV system more economical.
Quality LONGi Solar places great emphasis on the quality of its solar modules. In addition to complying with the conditions of the IEC 61215 and 61730 standards, LONGi Solar goes one step further and carries out the standard tests with three times longer test times. In concrete terms, this means that a Damp Heat Test has a running time of 3000 hours instead of only 1000 hours. This extra effort ensures that your modules meet the requirements of the standards over the entire life cycle.
Warranty In addition to a 12 year product warranty, LONGi Solar also offers a 25 year performance warranty. LONGi promises that after 25 years of operation, at least 84.8% of the module output will still be available. This value is above the industry standard of 80 %.
