Shingled solar panels

With the development of solar panels often we see the introduction of new ideas that are pushing the limits.

Shingled modules are likely the rightmost limit of crystalline silicon solar development.

Simply shingled modules cut solar cells into strips and overlap them inside the framed module.

True shingled modules have no visible busbars and solar cells are cut into five or six strips and connected with an electrically conductive adhesive.

There’s no real reason to keep solar cells at their large square size. By cutting cells even just in half, gaps can be eliminated and more silicon can fit on a panel. Shingled-cell strings can reach the entire length of a module without a gap — like in SunPower’s P-series.

The incremental technology is making more power from each square meter of panel space.
