Advanced Module Technologies: Solar Shingles
Solar shingles are a type of solar energy solution where solar panels are designed to look like conventional roofing materials, while also producing electricity. Solar shingles have several advantages.
First, a key advantage is that they eliminate the need for ribbon, connecting cells like roof tiles.
Second and related to the removal of the ribbon, module aesthetics are improved, as the panels are homogeneously coloured.
Third, unlike a standard cell, cells for shingle modules have busbars at opposite ends and cells are sliced into several strips, which reduces the current and consequently the load on fingers (metallic super-thin grid fingers, perpendicular to the busbar, collecting the generated DC current and delivering it to the busbars). This also enables a reduction in the number of fingers as well as their thickness, which decreases shading and improves the output power of the cell
