620W Jinko Bifacial Solar Panel

The 620W Jinko Solar Panel is a high‑performance N‑type bifacial photovoltaic module engineered for large‑scale residential, commercial, and utility‑scale solar installations. Built with JinkoSolar HOT 2.0 technology, this panel delivers superior efficiency, long‑term reliability, and increased energy yield compared to conventional P‑type modules.

Designed to generate power from both the front and rear sides, the 620W Jinko bifacial panel maximizes output by capturing reflected light from surrounding surfaces, significantly reducing the levelized cost of energy (LCOE).
