On the same roof or ground area, this translates into measurably higher energy yield without the need to expand the system footprint. - **PVEL Top Performer across all 7 test categories** - Emmvee is the only Indian manufacturer to achieve Top Performer status in all seven test categories of the 2024 Kiwa PVEL PV Module Reliability Scorecard — including thermal cycling, damp heat, PID, and hail. Only 9 manufacturers worldwide achieved this distinction — a result independently verified by an accredited laboratory, not a marketing claim. - **Low temperature coefficient — N-type TOPCon advantage** - The datasheet confirms a Pmax temperature coefficient of -0.29%/°C, which is characteristic of N-type TOPCon cells and significantly more favorable than standard PERC modules (-0.35 to -0.37%/°C). In the Polish climate, where modules routinely reach 60–70°C in summer, this difference delivers a real-world annual yield improvement of approximately 1.5–2% compared to previous-generation modules. - **~80% bifaciality in a glass-to-glass construction** - The module offers a bifaciality factor of ~80% (±5%) in a glass-to-glass configuration, which eliminates backsheet degradation and improves mechanical durability. On ground-mounted systems with a light-colored albedo surface, or rooftop installations with a white membrane, this enables a real energy gain of 5–15% compared to a monofacial equivalent. - **Low degradation — 0.40%/year (years 2–30)** - The warranted degradation is 1.0% in the first year and 0.40%/year over the subsequent 29 years, backed by a 30-year linear power warranty. By comparison, typical PERC modules degrade at 0.45–0.55%/year. Over a 30-year project lifetime, this difference compounds into several additional percentage points of cumulative energy production and a measurably improved project IRR. ## Cons - **Not listed as a Tier-1 bankable manufacturer per BNEF** - Based on available data, Emmvee does not appear on the BNEF Tier-1 bankable manufacturers list (as of Q1 2026), whereas a peer-comparable supplier such as Jinko Solar has held this status for years. For large-scale PV projects financed on a non-recourse basis by institutional lenders, the absence of a BNEF Tier-1 rating can complicate or increase the cost of project financing — making this series a less optimal choice for projects dependent on third-party debt financing. ## About this series Emmvee TITANIUM DUO panels introduce a new quality in the field of **bifacial half-cut** modules, focusing on maximizing yields per unit area. Thanks to the use of advanced bifacial technology, these modules effectively utilize light reflected from the ground, which is particularly crucial for professional ground-mounted installations or roofs covered with a bright membrane. They solve the real problem of limited mounting space, generating significantly more clean energy than traditional older-generation monofacial panels. The use of **half-cut cells** significantly reduces resistive losses and improves overall resistance to partial shading, which directly translates into more stable operation of the entire system in variable Polish weather conditions. This series stands out with **increased mechanical strength** and an excellent temperature coefficient, making it an ideal choice for the most demanding industrial investments and large-scale photovoltaic farms. Unlike many standard solutions available on the market, TITANIUM DUO offers **better power stability over time**, guaranteeing a predictable and safe return on investment. This solution is dedicated to experts and professionals for whom **high efficiency with limited maintenance** is key, placing these panels at the forefront of products with the best quality-to-price ratio. ## Notable figures - At 22.7% efficiency, this panel is on par with typical \*\*TOPCon 700-750W\*\* modules - At 226.9 W/m², this panel generates 3.2 W/m² less per unit area than \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 700-750W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #3307 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty does the Emmvee TITANIUM DUO carry and what does it cover? The Emmvee TITANIUM DUO comes with a 12-year product warranty covering physical and material defects, along with a 30-year linear power output warranty. The manufacturer guarantees that after 30 years the module will retain at least 87.4% of its nominal output power. Annual degradation from year two onward is just 0.40%, placing this series above the industry standard for premium TOPCon-class modules. ### Are the Emmvee TITANIUM DUO 635W panels suitable for utility-scale solar farms and ground-mounted installations? Yes, the TITANIUM DUO is engineered for ground-mounted systems and utility-scale farms. Its bifacial design allows the rear side of the module to harvest light reflected from the ground surface — bright gravel, concrete, or dry grass can increase real-world energy yield by 15–30% above the nominal 635 W rating. The module's high mechanical resistance to snow and wind loads of up to 5,400 Pa further confirms its suitability for large-scale installations. ### How does the TOPCon technology in the TITANIUM DUO series differ from conventional PERC panels? TOPCon (Tunnel Oxide Passivated Contact) is an n-type cell technology that, compared to PERC, offers a lower temperature coefficient, superior low-irradiance performance, and reduced light-induced degradation (LID/LeTID). In climates with frequent cloud cover, TOPCon panels generate measurably more energy on an annual basis than PERC modules of equivalent nominal power rating. ### Are the Emmvee TITANIUM DUO panels suitable for rooftops covered with light-colored PVC or TPO membranes? This is one of the optimal use cases for this series. White and light-gray roofing membranes exhibit a high reflectance coefficient (albedo 0.6–0.8), which directly feeds the rear side of the bifacial module. In such environments the TITANIUM DUO can achieve energy yields significantly exceeding the nominal 635 W rating, shortening the payback period for industrial and logistics rooftop installations. ### How do the Emmvee TITANIUM DUO panels handle partial shading from chimneys or HVAC equipment? The use of half-cut cells (144-cell half-cut format) means that each half of the module operates independently. Shading of even one cell string does not interrupt the operation of the remaining section of the panel, limiting energy losses and reducing the risk of hot spot formation. This is particularly important on industrial rooftops where technical infrastructure elements may cast shadows over part of the array. ### Is Emmvee an established solar panel manufacturer, and where is the company based? Emmvee is an Indian solar panel manufacturer with a long-standing history and its own vertically integrated cell and module production facilities. The company does not currently appear on the Tier 1 lists published by major rating agencies, which should be factored into any project-level financial risk analysis. That said, the TITANIUM DUO series carries standard IEC certifications with verified warranty parameters, and the 12-year product warranty is comparable to offerings from leading global brands. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/G12_N-Type_TopCon_Bifacial_Glass_to_Glass_new-2e4b64eac28b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -30 W, lighter, +2.3 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.3 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -35 W, lighter, +2.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -35 W, lighter, +2.1 pp | | [Emmvee E700HCBG 132-T](https://comparepv.com/panel/emmvee-e700hcbg-132-t) | 700 W | Very close match | | [Emmvee E710HCBG 132-T](https://comparepv.com/panel/emmvee-e710hcbg-132-t) | 710 W | Very close match | | [Emmvee E715HCBG 132-T](https://comparepv.com/panel/emmvee-e715hcbg-132-t) | 715 W | +10 W, +0.3 pp | | [Emmvee E720HCBG 132-T](https://comparepv.com/panel/emmvee-e720hcbg-132-t) | 720 W | +15 W, +0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +100 W, cooler, +2.4 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +95 W, cooler, +2.2 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +90 W, cooler, +2.1 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +85 W, cooler, +1.9 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +55 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/emmvee-e705hcbg132-t Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
