The Phono Solar Bifacial Twinplus Module (HIGH EFFICIENCY MONO-PERC BM6-10B-G) is designed for installations where real energy yield matters across various conditions-beyond just ideal exposure. The use of bifacial construction actively utilizes reflected light from the ground, translating into higher production where conventional modules reach their limits. Simultaneously, mono-PERC technology supports stable performance across a wide range of irradiance levels, and the combination of half-cut with multi-busbar helps minimize cell connection losses and improves module performance under partial shading.

In practice, this series addresses common investor challenges: yield losses in hot weather, sensitivity to partial shading, and the risk of accelerated degradation. Its reinforced structure with dual-glass and POE encapsulation enhances PID resistance and increases reliability in harsh environments.

This is an excellent choice for utility-scale PV farms, ground-mounted systems, carports, and commercial installations, where predictable production and a better LCOE compared to standard monofacial modules are key priorities.

What owners get
Bifacial design boosts energy yield

The dual-sided module design captures reflected ground light (albedo), delivering additional energy production versus comparable monofacial modules in ground-mount, carport, and utility-scale PV installations.

Half-cut + multi-busbar reduce losses

Combining half-cut cells with multi-busbar technology lowers resistive losses and improves module behavior under partial shading, which matters for commercial installations with irregular shadow patterns.

Double glass and POE encapsulation

The double-glass construction with POE encapsulation (instead of standard EVA) increases resistance to potential-induced degradation (PID) and improves module sealing in humid or demanding operating environments.

Tier-1 manufacturer, 9 years on BNEF list

Phono Solar has been included on the BloombergNEF Tier 1 list for the ninth consecutive year (confirmed in Q2 2024), reflecting stable project bankability and a proven track record of large-scale PV deliveries.

Competitive efficiency versus segment peers

Maximum efficiency of 21.48% at up to 555 Wp places this series directly alongside comparable tier-1 products (ET Solar Elite PLUS 21.4%, Boviet VEGA 21.3%, JA Solar DEEP BLUE 3.0 21.5%), with no meaningful gap from the top of the PERC segment.

Trade-offs
Production discontinued in 2024

The series has been discontinued (released 2020, ended 2024), meaning limited availability of matching replacement modules for expanding existing installations and potentially slower response times for warranty servicing.

Product warranty below current market standard

The 12-year product warranty is shorter than the 15 years now offered by many Tier-1 manufacturers on newer TOPCon series, positioning this mono-PERC series' warranty terms as dated relative to the 2026 market baseline.

Notes from the database

About the Bifacial Twinplus Module Series (HIGH EFFICIENCY MONO-PERC BM6-10B-G) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the maximum power output of the Phono Solar Bifacial Twinplus BM6-10B-G series and what affects real-world yield?
Modules in the BM6-10B-G series reach up to 555 Wp peak power on the front side. Thanks to the bifacial design, the rear side also captures light reflected from the ground surface, which under favorable conditions (high-albedo ground, adequate clearance) can add several to over ten percent on top of the nameplate rating. Actual bifacial gain depends on ground albedo and mounting height.
How do Phono Solar BM6-10B-G modules perform in high summer temperatures?
The BM6-10B-G series uses mono-PERC cell technology with a relatively low power temperature coefficient of approximately -0.35%/°C. This means power losses on hot days are kept to a minimum compared to standard polycrystalline modules. The dual-glass construction also aids heat dissipation, supporting stable output under demanding climate conditions.
Are Phono Solar Bifacial Twinplus BM6-10B-G panels resistant to partial shading?
Yes. The BM6-10B-G series combines half-cut cell technology with a multi-busbar layout. Half-cut cells reduce cell-level resistance and limit current mismatch losses when part of the module is shaded - only the shaded half-strings are affected while the rest continues operating normally. The multi-busbar design further reduces thermal stress and interconnect losses, improving overall performance near chimneys, trees, or inter-row shading.
What are the product and power output warranties for the Phono Solar BM6-10B-G series?
Phono Solar provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty with guaranteed minimum power levels over the entire 30-year period. To claim warranty service, retain the purchase invoice and installation documentation and contact an authorized Phono Solar distributor.
What types of installations is the Phono Solar Bifacial Twinplus BM6-10B-G series best suited for?
The BM6-10B-G series is designed primarily for utility-scale PV farms, ground-mounted systems, carports, and commercial or industrial rooftops. Bifacial modules require adequate ground clearance (typically 0.5-1 m) and a reflective surface to generate meaningful rear-side yield. The reinforced dual-glass construction with POE encapsulation performs well in demanding environments with elevated humidity or aggressive weather exposure.
Is the Phono Solar Bifacial Twinplus BM6-10B-G series still available for purchase?
The BM6-10B-G series has been discontinued by Phono Solar and is no longer in active production. Remaining stock may still be available through select distributors or on the secondary market, but availability is limited. For new projects, it is advisable to consider current Phono Solar series or equivalent Tier 1 bifacial mono-PERC modules from other manufacturers.
