Canadian Solar CS3K SuperPower Solar Panel - 280W (CS3K-280P)


The KuPower - or CS3K-P - line of Canadian Solar modules features 120 polycrystalline cells in a standard 60-cell module footprint. While the larger number of smaller cells improves performance in partial shade, these modules are defined by their innovative Low Internal Current (LIC) technology, which reduces operating temperature and power loss in the internal cell connections.

Like all solar panels from Canadian Solar, these modules provide high system energy yield and feature enhanced anodized aluminum alloy frames that ensure the ability to handle 6000 Pa snow loads and 4000 Pa wind loads.
