BISOL Group announced on 16 January 2023 that the first batch of its best-selling BISOL Duplex in a full-black 400-420 Wp version, together with its frameless version, BISOL Laminate, "will already be available in February"1. The modules use the M10 format with 10 thin-wired busbars, which the maker says enable greater power output, higher efficiency and superior temperature performance1.
The announcement set out a sequence of availability dates rather than a single launch. The first BBO (larger) modules, BISOL Bifacial and BIPV modules "will be on the market in March"1. BISOL Supreme, described by the maker as the only solar module in the world providing a 25-year 100% output power guarantee, will be available in a 400 Wp version1. BISOL Spectrum, the coloured modules designed to blend with buildings and roofs of various types and styles, especially in historical settings, "will be at your disposal by April"1.

For the new bifacial modules, BISOL cites "the smaller and differently shaped junction box" as an additional advantage, saying it "enables even less shading when compared to the M6 generation"1. The company describes itself as the biggest real EU producer of premium quality solar modules, and refers to record sales in 20221. The same announcement was published in Dutch, German and French, with the same dates and figures2.
Why it matters for households
Module format and cell layout affect how much of a roof's area can be turned into generating capacity, and how a system behaves when part of an array is shaded. BISOL states that the M10 generation offers greater power output, higher efficiency and better temperature performance than the previous generation, and that the revised junction box on the bifacial modules reduces shading compared with the M6 generation1. For a household, those are the two practical variables: how much output a given roof area can carry, and how much a chimney, dormer or tree costs in lost generation.
The full-black finish and the coloured Spectrum range are aimed at appearance rather than output, with BISOL noting that the coloured modules were designed to blend with buildings and roofs of various types and styles, especially in historical settings1. That matters where a roof is visible or where a property sits in a sensitive setting, since it widens the range of roofs on which panels might be considered acceptable.
The 25-year 100% output power guarantee attached to BISOL Supreme is a warranty term rather than a performance figure, and it is the maker's own description of the product1. No UK pricing, distributor list, stock levels or confirmed UK delivery dates appear in the announcement, and none have been reported here.
What happens next
BISOL gives February for the first Duplex and Laminate batch, March for the first BBO, Bifacial and BIPV modules, and April for Spectrum1. The maker points readers to its datasheets for specifications1. No further dates have been announced.
