Middle of its segment, heavy for its output
The Emmvee Titanium Duo is a two-sided N-type TOPCon module with a glass-glass construction, designed for stable operation over many years in demanding conditions. Thanks to its bifacial design, the panel utilizes not only direct sunlight, but also reflected light from the ground, which significantly improves energy yields in situations where every meter of installation matters - on building roofs, ground-mounted farms, and carports. The use of N-type cells in the TOPCon technology reduces typical power losses over time and helps maintain high energy production even at elevated operating temperatures. The two-layer construction increases resistance to microcracks, moisture, and environmental factors, which is particularly important in installations near industrial areas or areas with high corrosion rates. Titanium Duo stands out for its combination of high efficiency, robust mechanics, and versatility - it is the choice for investors who expect predictable yields and durability without compromising.

Emmvee is one of only 4 manufacturers worldwide — and the only one from India — to achieve Top Performer status in all 7 PQP categories of the 2024 Kiwa PVEL PV Module Reliability Scorecard, including LID+LETID, PID, Damp Heat, and Hail Stress Sequence. This independent validation of manufacturing quality is on par with leading Chinese brands.
The peak efficiency of 22.45% is virtually identical to the EGing STAR Pro (22.45%) and JA Solar DEEP BLUE 4.0 (22.5%), and exceeds the ZNShine ZXM7-UHLD144 (22.44%). The series matches its direct peer comparables in power density — a key advantage in space-constrained installations.
The linear power warranty assumes an annual degradation rate of 0.40% (after the first year at 1.0%), guaranteeing at least 87.4% of nominal power output after 30 years. This is in line with the industry standard for N-type TOPCon cells and comparable to the warranty terms offered by JA Solar and Trina Solar in this segment.
A bifaciality factor of ~80% (±5%), combined with dual 3.2 mm glass lites, delivers real energy yield gains from ground-reflected irradiance — particularly on ground-mount farms, carports, and light-colored industrial rooftops — while eliminating PID degradation and moisture ingress through the module rear, as confirmed by the PVEL Damp Heat result.
The power temperature coefficient of −0.29%/°C is more favorable than the typical −0.34%/°C for PERC cells, translating to approximately 1.5–2% higher energy yield on hot summer days when module temperatures reach 60–75°C — a meaningful advantage for commercial installations operating throughout the summer months.
Emmvee does not appear on the Bloomberg NEF Tier 1 list (confirmed in manufacturer data: tier_1_bankable: false). For utility-scale PV projects financed through bank debt or institutional leasing, the absence of this status may require additional risk assessment by lenders or preclude the use of standard insurance clauses — unlike JA Solar, Trina Solar, and Jinko Solar, all of which hold Tier 1 status.
- Efficiency of 21.7% is 0.8pp below the TOPCon 550-600W median (22.4%)
- At 216.9 W/m², this panel generates 7.5 W/m² less per unit area than TOPCon 550-600W median (224.4 W/m²)
- At -0.29%/°C, hot weather performance is typical for TOPCon 550-600W panels
- Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface
- #7542 for efficiency, #2165 for temperature performance out of 14005 panels
