Middle of its segment, heavy for its output
The Titanium Duo series is engineered for installations where maximizing energy yield goes hand in hand with resilience against demanding operating conditions. The modules use N-type TOPCon half-cut cells, which reduce current losses, improve performance under partial shading, and deliver more stable output at high temperatures compared to conventional PERC modules. A defining feature of the series is its glass-to-glass bifacial construction, allowing the module to capture additional energy from light reflected off the ground - a real advantage on light-colored roofs and in ground-mounted installations. Robust build quality and high mechanical resistance to snow and wind loads make the Titanium Duo well suited for both commercial rooftops and demanding utility-scale solar farm projects, where durability directly affects lifetime energy cost (LCOE). The series also stands out for its low annual power degradation, ensuring stable energy output even after many years in service. It's a solid choice for installers and investors seeking the right balance between performance, durability, and predictable return on investment.

Signals from the data
Commercial, utility-scale and shaded-installations.
Weight-limited structures.
Bottom 13% of the TOPCon 600-650 W segment, against a median of 53.1.
The top efficiency (23.51%) matches Jinko Solar's Tiger Neo 66HL4M-(V) 635W, one of the leading TOPCon modules on the market, and clearly outperforms RedSolar M10R-MBB and Renesola RS7 (22.72%).
Dual glass (2 mm front + 2 mm back) and bifaciality of roughly 80% (±5%) deliver additional energy yield from reflected irradiance and better resistance to moisture and PID degradation than backsheet modules.
The manufacturer guarantees a minimum of 87.4% of nameplate power after 30 years — in line with the standard set by leading TOPCon manufacturers (e.g., Jinko Tiger Neo), supporting predictable lifecycle energy yield.
The half-cut N-type cell layout reduces current losses under partial shading and offers lower LID degradation and better high-temperature performance than older PERC technology.
22 variants within the series allow precise matching to project requirements — from rooftop installations to ground-mount farms — without switching product families.
Emmvee (India, founded 1992) does not appear on the BNEF Tier 1 bankable manufacturers list, unlike Jinko Solar in the comparable peer set. This can complicate bank financing for large commercial projects despite comparable technical specs.
- Efficiency of 22.8% matches the TOPCon 600-650W median
- At 227.7 W/m² power density, roof space requirements are typical for TOPCon 600-650W panels
- Temperature coefficient of -0.29%/°C matches the TOPCon 600-650W median
- At 34.0 kg, this panel is 1.3 kg heavier than the TOPCon 600-650W median (32.7 kg) - more demanding for installation crews
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

Datasheet charts
Measured curves published by Emmvee in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 615 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
