JinkoSolar JKM620N-66HL4M-BDV

Laboratory DC nameplate power; this is not an annual energy estimate.

Module voltage without a load. It is not household voltage.

Module operating voltage at STC.

Module current under the stated test condition.

Module operating current at STC.

Exact STC power column, not bifacial rear-side gain.

Nominal manufacturer dimension.

Nominal manufacturer dimension.

Unknown thickness is never inferred from a nearby model.

Shown only when this field has passed integration review.

Bifacial modules can receive light on both faces; this is not a yield prediction.

Nominal weight for this documented construction.

Change in rated power per degree; sign and test basis matter.

Required for temperature-corrected voltage calculations.

Manufacturer coefficient under its stated test conditions.

NMOT is distinct from STC cell temperature.

NOCT is not substituted for NMOT.

A module rating, not approval of a proposed string.

Installation protection still requires a separate design review.

Rear/front power ratio under the documented condition, not a production uplift.

Manufacturer operating range; not ambient design temperature.

Observe the stated qualifications, including short-term limits.

Eligibility and market-specific conditions must be reviewed.

Different market variants are not assumed interchangeable.

The family label does not establish equivalence.

Specifications can change between document revisions.

Unknown when not established in the approved record.

Date recorded in the source evidence.

Date of the independent import review.
