WHAT ARE SHINGLED SOLAR PANELS?

Conventional solar panels use various numbers of solar cells depending on the desired output of the panel. The solar cells are laid out across the panel with spaces between them.  They are electrically connected together using copper busbars (ribbons) by means of high temperature soldering processes.

The solar cells are laid out across the panel with spaces between them.  They are electrically connected together using copper busbars (ribbons) by means of high temperature soldering processes.

The more copper busbars used the less resistance losses and hence the more efficient the electrical connection.  This is one of the reasons many solar panel manufacturers have increased from 3 busbars to 4, 5 or 6.   However, having more busbars covering the cells means there is less of the solar cells exposed to sunlight, reducing output of the cells by as much as 3.5%.  There is typically over 30 metres of busbars required per solar panel to enable all of the connections.

Shingle solar cells are solar cells which are cut into typically 5 or 6 strips.  These strips can be overlaid, like shingles on a roof, to form the electrical connections.  The strips of solar cells are joined together using an electrically conductive adhesive (ECA) that allows for conductivity and flexibility.

1).Less Energy Loss Due To Shading

Conventional solar panels have the individual cells wired in series so when a part of the solar panel is shaded it can have a significant effect on the level of power output.  By configuring the solar cells in shingles, they can be wired in groups and configured in parallel which significantly reduces the losses caused by shading.

2).Better Reliability

Low Busbar Failures

Shingle solar panels do away with approximately 30 metres of busbar and soldered joints that is required on conventional solar panels, so busbar failures are reduced.

Better Mechanical Performance

Static and dynamic load tests show that the shingle approach is more resistant to failure due to external forces being applied to the solar panel compared to conventional solar panels.

3).More Attractive

Shingled solar panels have no visible circuitry which give them clean simple look providing superior street appeal.

As solar panel technology continues to mature, shingled modules represent the current state-of-the-art in terms performance, reliability and aesthetics.
