Solar panel bus vs tab.
Skoolies tend to have a lot of roof space which allows for a wide variety of solar array configurations.
Hence the bus wire has to be thicker and broader.

Select solar charging system.
200 watts on 12 volts x1 2 20 amps.
During the module manufacturing process string and tab wires are soldered to the busbars to connect solar cells in a combination of series and parallel.

Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency.
Bus wire is used to carry the current across each row.
The cluster of strings are then connected to the solar junction box.
Solar busbar development trends and future.
As a matter of fact tabbing wire and bus wire for solar modules are generically the same.
4 1 out of 5 stars 11.
The easy way to decide what size of charge controller you need is to divide the input wattage by the system voltage and multiply by 1 2 for safety if you have 400 watts of solar panels charging a 12 volt system 400 12 you get 33 33 amps.
Both are sold in rolls of various sizes.
This gives you room to add more panels in the future if you find you need more energy.
Tab wire is used to connect individual cells in series and the bus wire connects these rows in parallel.
Only the bus wire has to carry the bus current which is many times larger than the row current.
The tab wire is brazed either manually or automatically to the solar cell busbar which connects the individual cells in series with a low series resistance.
Then the ends these rows are connected in parallel to obtain the desired current capability.
Multiply by 1 2 and you need a 40 amp charge controller.
Tab wire or tabbing wire is flat copper wire.
In order to obtain suitable voltages cells have to be connected in series forming rows.
The solar photovoltaic cells have to be connected in series which form rows to obtain suitable voltages.

Bus wire or connecting wire looks like tab wire but is much wider.
Shown below is an image showing the busbars and the grid finders of a typical solar cell.
