Vikocell diy solar panel solar cell tabbing wire kit 200ft tab wire with 20ft bus wire and 3pcs flux pen.
Solar panel bus vs tab.
As a matter of fact tabbing wire and bus wire for solar modules are generically the same.
The cluster of strings are then connected to the solar junction box.
Skoolies tend to have a lot of roof space which allows for a wide variety of solar array configurations.
Only the bus wire has to carry the bus current which is many times larger than the row current.
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.
Bus wire or connecting wire looks like tab wire but is much wider.
Tab wire is used to connect individual cells in series and the bus wire connects these rows in parallel.
This gives you room to add more panels in the future if you find you need more energy.

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.
The solar photovoltaic cells have to be connected in series which form rows to obtain suitable voltages.
It can range from 2 5mm to 5mm depending on the power of the panel and size.
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.
Solar busbar development trends and future.
Tab wire or tabbing wire is flat copper wire.
Bus wire is used to carry the current across each row.
In order to obtain suitable voltages cells have to be connected in series forming rows.
Then the ends these rows are connected in parallel to obtain the desired current capability.
Both are sold in rolls of various sizes.

Shown below is an image showing the busbars and the grid finders of a typical solar cell.

Multiply by 1 2 and you need a 40 amp charge controller.
Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency.
Hence the bus wire has to be thicker and broader.
