Perlight Delta Black

Perlight Delta Black is a current single-glass solar-panel family with a black appearance, represented in the UK by two code-specific module formats.

The full PLM code identifies the dimensions, cell arrangement, cable length and connector record that the headline wattage leaves open.

The two Delta Black formats

The PLM-415OM6B-60 sheet covers four power variants, while the PLM-425OM10A-44B sheet covers five. The current UK page foregrounds the highest-power version from each document.

The modules have different length and width measurements. They also differ slightly in weight, cell layout, cable detail and the mechanical-load information printed in their sheets.

Both documents describe monocrystalline passivated-emitter-and-rear-cell technology. The UK representative groups the family under its shingle-cell wording. These are single-glass modules, separate from Perlight’s dual-glass Black Grid family.

Output and warranty record

The power temperature coefficient describes the change in module output as cell temperature changes. It is separate from the warranted degradation schedule, which sets an initial allowance followed by an annual allowance over the performance-warranty period.

The two datasheets use the same temperature coefficient and warranty schedule. Their efficiency ranges differ because each sheet covers a different set of power variants and a different module area. A percentage from one code should not be transferred to the other.

The product and performance periods in the table are datasheet statements. The warranty document supplied with the module determines the detailed conditions and claim route.

Current product identity

Both headline versions appeared on the UK representative’s current module page on 23 July 2026. Perlight’s manufacturer range also listed PLM-425OM10A-44B at that date. Current supply or certification still depends on the exact code rather than the family name.
