BISOL Group announced on 16 January 2023 that the first of its larger M10 modules, the BISOL Bifacial and BIPV ranges, "will be on the market in March"1. The company described these as its first BBO (larger) modules1. The announcement covers a staggered release across its M10 generation, which the maker says uses "new M10 solar modules with 10 thin-wired busbars"1.
The first batch of the company's best-selling BISOL Duplex, in a full-black 400-420 Wp version, together with its frameless BISOL Laminate variant, "will already be available in February"1. BISOL Supreme, which the maker describes as the only solar module in the world providing a 25-year 100% output power guarantee, "will be available in a 400 Wp version"1. The coloured BISOL Spectrum range, designed to blend with buildings and roofs of various types and styles, especially in historical settings, "will be at your disposal by April"1.
BISOL states that the additional advantage of the new bifacial modules is "the smaller and differently shaped junction box" which "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 says the M10 busbar design enables greater power output, higher efficiency and superior temperature performance1.
"The first BBO (larger) modules, BISOL Bifacial and BIPV modules will be on the market in March."
The same dates appear in the company's Dutch, German and French versions of the announcement, which also place the Duplex and Laminate batch in February, the bifacial and BIPV modules in March and Spectrum by April2. The German text refers to the modules as "BISOL Duplex BBO (größeren) Module" alongside the Bifacial and BIPV ranges3. No UK pricing, efficiency figures, dimensions or warranty terms for the bifacial and BIPV modules have been reported in these announcements.

Why it matters for households
Bifacial modules generate from both faces, so output depends on what lies behind and beneath the array, such as a light-coloured roof surface or a raised mounting system. The maker's claim that a smaller, reshaped junction box reduces shading relative to the M6 generation points to a practical detail on bifacial and glass-glass solar panels: the junction box sits on the module and can cast a shadow across cells. For a household weighing up a roof array, the arrival of larger-format modules from an EU-based maker widens the field of panel sizes and formats available through UK installers, which affects how a given roof area is filled and how much capacity fits within the same footprint. The coloured Spectrum range addresses a different constraint, the appearance of panels on visible roof slopes and in conservation areas, where planning or aesthetic limits can otherwise rule out solar. None of the announcements state UK availability, distributor arrangements or prices, so what reaches UK roofs, and when, has not been reported.
What happens next
The maker's stated sequence runs from February for the Duplex M10 and Laminate, March for the bifacial and BIPV modules, and April for Spectrum1. No further dates have been announced. Households considering BISOL solar panels for UK roofs can expect specification details to appear in the maker's datasheets, which the announcements direct readers to1.
