Innovative monocrystalline solar modules with shingle cell technology. Conventional solar modules use copper connectors to link individual photovoltaic cells together. These thin cell connectors are eliminated in the unique shingle cell solar modules: instead of single cells, narrow cell strips are used. This cell technology removes the need for cell connectors. The cells are interlocked like roof shingles: the end of one cell is simply connected to the beginning of the next cell with a special polymer-based adhesive that is conductive due to metallic particles. This creates a unique parallel structure that allows for an unobstructed flow of energy. This special design reduces internal losses and increases module performance. Many of the modules available on the market often face issues with localized heat development. The so-called hotspots are a thing of the past with shingle cell technology. The parallel cell strip interconnection not only prevents hotspots but also mitigates shading issues. All these effects lead to an even longer lifespan of the module and extremely high reliability. With the integrated bypass diodes in the junction box, the module can continue to produce electricity even in shaded or low light conditions.
