100% PV modules, CE certified, are built using in-house produced cells, allowing us to carefully ensure quality at every step in manufacture. Before being assembled into modules, each cell is individually inspected and power-matched to ensure consistent performance between the cells in the module array. Excellent raw materials are the foundation for a top quality solar module. Solarfun completes rigorous materials testing before and during module production in order to ensure that only the best becomes part of a Solarfun module. Once assembled, each of our PV modules undergoes further testing to ensure consistently high quality. Every module is given a complete visual inspection to verify that its appearance meets our standards. Our modules then undergo further testing via a calibrated solar simulator to ensure an accurate minimum power, voltage, and current rating.
