ROVO 550W Mono Solar Panel Half Cells 25 Years Life

详情

ROVO Monocrystalline solar panels (or mono panels) are made from monocrystalline solar cells. Each cell is a slice of a single crystal of silicon that is grown expressly for the purpose of creating solar panels.

In the lab, the crystal is grown into a cylindrical log shape called an ingot and is then sliced into thin discs. Each disc is cut along the edges to form octagons.

When the solar cells are placed on the solar panel, the octagonal shapes help the solar panels fit a maximum number of solar cells into the array. It’s much like cookies on a baking sheet. Even tightly spaced round cookies always have spaces between them, but octagonal cookies can be placed tightly together with little wasted space.

Distinctive for their black color, monocrystalline solar panels typically have an efficiency range of between *5% to *0%, with some newer experimental models even reaching close to *0%.
