Description
Product Overview
The Jinko 640W Bifacial Half-Cut Solar Panel is a high-output N-type TOPCon module for commercial rooftops, industrial sites and ground-mounted arrays. Its glass-glass bifacial build lets the rear side add energy from reflected light.
It is one of the higher-power solar panels in our range. Confirm Vmp, Voc and Isc in the official Jinko Solar documentation before you size strings.
Key Features
- 640W rated power: Produces more energy per module, so you need fewer panels for a given array.

Why Choose this Solar Panel?
High power per panel lowers the cost of racking, cabling and labour across a project. TOPCon cells and a glass-glass build also suit hot climates where durability matters.
For a similar panel with slightly less output, see the Jinko 625W Bifacial Half-Cut Solar Panel.
Applications
This panel is suitable for:
- Commercial and industrial rooftops
