4 Frequently Asked Questions about "There are white spots on the main grid line of the photovoltaic panel"

What are the white lines on photovoltaic modules?

The white lines on photovoltaic modules serve one of three important purposes, depending on whether they're the gaps, the fingers or the busbars. The gap lines are spaces between the solar cells, through which you can see the panel's white backing. The gaps are necessary to allow for thermal expansion of the cells when the panels heat in the sun.

Why do PV panels have white lines?

The answer lies in the way PV panels are designed and constructed. The white lines on photovoltaic modules serve one of three important purposes, depending on whether they're the gaps, the fingers or the busbars. The gap lines are spaces between the solar cells, through which you can see the panel's white backing.

What are the gap lines on solar panels?

The gap lines are spaces between the solar cells, through which you can see the panel's white backing. The gaps are necessary to allow for thermal expansion of the cells when the panels heat in the sun. Both the fingers and the busbars are electrical conductors.

What are worm marks on solar panels?

Snail trails or worm marks are short thin dark lines on the surface of a solar panel. Just to clear it up: they have nothing to do with actual snails. They may appear several years after the installation along the edges and, most importantly, where microcracks are located.
