Solar panel is an assembly of solar cells that synthesizes the sunlight into electricity. As a solar panel is an assembly of many solar cells, it requires internal connections/wiring between these solar cells known as tabbing. In order to get the highest possible output from a solar photovoltaic installation, it is necessary for the solar cells to be tabbed with care. In this blog, you will learn about the challenges in solar cell tabbing.
Challenge #1: Positioning
The
tabbing ribbon or wire, including the bus ribbon or wire, has to be positioned
precisely on the solar cells. Tabbing wires collect the power generated in the
cell and send it to the bus ribbon – which means that achieving the optimum
area of collection for each tabbing ribbon would help achieve the maximum
output from the solar panels. One solution to this is using computerized
operations.
Challenge #2: Continuity
It
is important to achieve seamless tabbing which is continuous. Breakage in
soldering tabbing wire onto a solar cell can result in poor efficiency.
Challenging as it is, fair amount of concentration can help you get tabbing
right.
Challenge #3: Quantity
Getting
the right amount of tabbing wires on each cell helps optimize collection of
current. Too much tabbing results in wastage of cell area that could otherwise
have produced electricity.
While
solar panel assemblies can be challenging, above mentioned simple tabbing solutions
can help optimize the process.
