Perlight Black Grid
Perlight Black Grid is a current N-type, dual-glass solar-panel family with two code-specific module sizes and front-and-rear test data.

The 465 W model is a 96-half-cell module with the code PLM-465DH8NHB-96, even though the PDF download filename ends in 120.
Cell description by model code
The 500 W model uses TOPCon cells. The 465 W model is specified only as N-type monocrystalline.
The 500 W code uses a different cell count and a longer frame. The handover record therefore needs the code printed within the applicable document rather than a family name or download filename.
Front and rear test values
Each variant has a front-side value and a separate back-side test-condition value using a fixed rear irradiance. The back-side value does not replace the front-side Standard Test Conditions rating used as the module’s headline power.
Both products use equal-thickness front and rear glass. Array geometry, weight calculations and replacement matching still depend on the full code, even though both products carry the Black Grid name.
Warranty and current record
The warranty graphs show the same first-year point and year-30 end point. Detailed warranty conditions come from the document applicable to the supplied unit.
Both model codes appeared on the official UK representative’s range page on 23 July 2026. Perlight’s manufacturer site also carried a current page for the 500 W code. A live MCS (Microgeneration Certification Scheme) record, where required, must still match the exact module code.
