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 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.
There have been a variety of recent advancements in conventional solar panel designs to help eliminate gaps between solar cells and decrease power loss caused by busbars.

Tiling ribbon (TR) technology

Tiling ribbon technology has busbars as per conventional solar panel design. However, these busbars (ribbons) are redesigned to increase the solar radiation onto the solar cells and also allows the solar cells to be mounted closer together.

Seamless Soldering Technology

Seamless soldering technology also has busbars like conventional solar panels. This approach uses a solder ribbon to allow the gap between the solar cells to be eliminated increasing the number of solar cells per square metre.

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 conductivity and flexibility.

This allows the cells to be connected differently to conventional solar panels, in that, there are no busbars (ribbons) required and the solar cells can be joined together resulting in no gaps between the solar cells.
Shingled solar modules can also be wired differently to conventional solar panels. Typically, solar cells in conventional solar panels are wired in a series of strings whereas the solar cells in shingled panels can be wired in parallel configuration.

Higher power per square metre
The shingled solar cells do not require busbars across the top of the cells so more of the solar cells are exposed to sunlight. The cells do not need to be spaced apart like in conventional solar panels so the solar panel area can produce more energy.

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

Bellow are some examples of shading and losses for a conventional
solar panel and shingled panel. The Shingled
Panels have greater performance except for the vertical
shading example.
Outdoor

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.
