The temperature coefficient for N-type is approximately -0.30%/°C versus -0.35%/°C for PERC, which at Polish summer temperatures (35°C+) translates into measurably higher annual energy yield at no additional cost. - **22.4% Efficiency Above Peer Group Median** - Peak efficiency of 22.4% outperforms the S-Energy SL45-78BGI peer (20.6%) by 1.8 percentage points and is virtually on par with the PolyCrown Solar Monocrystalline120 (22.42%). Only the Gokin GK-5-54HGb reaches 24.3%, but that is an outlier — the Emmvee series sits clearly above the median of this comparison group. - **Top Performer in All 7 Kiwa PVEL 2024 Test Categories** - Emmvee is one of only 9 manufacturers worldwide — and the sole Indian company — to achieve Top Performer status in all 7 categories of the Kiwa PVEL Product Quality Program 2024 (PID, LID+LETID, Hail, Thermal Cycling, Damp Heat, Mechanical Stress, and PAN). A warranty claim rate of 0.0002% of revenue independently confirms production-line reliability. - **Lightweight Glass-to-Backsheet Construction** - Using a black polymeric backsheet instead of a rear glass pane reduces module weight to approximately 21–22 kg, compared to 27–29 kg for glass-glass modules in the same power class. This lowers roof structural loading and simplifies installation without compromising certified mechanical strength ratings. - **Full Black – Seamless Integration with Dark Rooftops** - The black backsheet combined with a black anodized frame delivers a uniform aesthetic free of the contrasting silver elements visible on most competing modules. In the premium rooftop segment — particularly on ceramic and concrete tile roofs — this visual advantage directly influences investment decisions. ## Cons - **Not Listed as BNEF Tier 1 Bankable** - Emmvee does not appear on the Bloomberg NEF bankable manufacturer list as of Q1 2026. For commercial projects ≥50 kWp financed through bank debt, financial institutions routinely require Tier 1 bankable status from the module manufacturer — its absence may block financing approval or increase the cost of debt. - **12-Year Product Warranty — Below Segment Leaders** - Jinko Solar, LONGi, JA Solar, and Canadian Solar all offer a standard 15-year product warranty on N-type modules. The Emmvee TITANIUM BLACK series provides only 12 years, meaning that over a 25-year operating horizon, the system owner carries 13 years without manufacturer warranty coverage against mechanical and production defects. - **Monofacial Design – No Albedo Gain** - The monofacial construction foregoes the additional 4–15% energy contribution from ground-reflected irradiance available with bifacial modules (e.g., glass-glass variants in the same power class). For ground-mounted systems with light-colored surfaces or in Polish climates with a snow-reflection effect, this difference is quantifiable at approximately 15–25 kWh/kWp per year. ## About this series Emmvee TITANIUM BLACK N-TYPE MONOFACIAL GLASS TO BLACK BACK SHEET MODULE panels redefine the standards of aesthetics and efficiency in modern photovoltaic installations. The use of advanced **N-type cell technology** effectively eliminates the problem of LID degradation, which guarantees stable energy production for decades. This series stands out with a unique construction combining glass with a black backsheet, providing the modules with lower weight while maintaining the highest mechanical strength. A key advantage is the **elegant Full Black design**, which makes the panels blend perfectly with dark roof surfaces, solving the problem of unsightly silver frames seen in competitors. Thanks to an optimized **temperature coefficient**, these modules operate more efficiently on hot days, which significantly distinguishes them from standard P-type panels.

In the Polish climate, where cloudy days are the norm, this technology allows for a faster return on costs. Solid workmanship and an innovative approach to silicon cells make these modules a real alternative to global brands, offering uncompromising durability without unnecessary marketing. ## Notable figures - Efficiency of 22.4% matches the \*\*N-type 450-500W\*\* median - Power density of 223.6 W/m² matches the \*\*N-type 450-500W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - #4774 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty does the Emmvee TITANIUM BLACK N-TYPE series carry, and what exactly does it cover? The Emmvee TITANIUM BLACK N-TYPE series is backed by a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. This means the manufacturer guarantees a defined minimum energy yield for a full quarter century of operation. This warranty scope is standard for modules in this class and is comparable to what leading global manufacturers offer. ### How does the N-type cell technology in the TITANIUM BLACK series differ from conventional P-type panels? The N-type cells used in the TITANIUM BLACK series are not susceptible to LID (Light Induced Degradation), a phenomenon that progressively reduces the output of traditional P-type panels within the first weeks of operation. Additionally, N-type modules exhibit a more favorable temperature coefficient, meaning they lose less power on hot days. In practice, this translates to higher annual energy yields and a slower long-term decline in power production. ### Will the Emmvee TITANIUM BLACK 485W panels perform well on overcast days typical of the Polish climate? Yes. N-type technology delivers superior low-light performance compared to standard P-type cells. In Poland, where overcast conditions account for a significant portion of the year, this characteristic meaningfully increases annual energy yield. The module's rated peak power is 485 Wp; however, its effective output under diffuse irradiance is one of the primary arguments for choosing this series in climates with frequent cloud cover. ### Does the Full Black appearance of the TITANIUM BLACK series affect panel efficiency? The black backsheet and black anodized frame enhance the aesthetic of the installation without reducing module efficiency. The TITANIUM BLACK series is a monofacial module, meaning it absorbs light exclusively from the front surface, so the color of the rear layer has no impact on energy production. The only difference compared to standard modules is a marginally higher operating temperature of the black surface; however, this is offset by the superior temperature coefficient of the N-type cells. ### Is Emmvee a reliable manufacturer, and is it worth choosing their panels over global market leaders? Emmvee has been operating since 1992 and is the only Indian manufacturer to have passed all seven categories of the Kiwa PVEL 2024 PV Module Reliability Scorecard. The company has a production capacity exceeding 7 GW. Although Emmvee does not appear on Tier 1 lists under certain bankability classifications, its results in independent durability and stress testing place it among manufacturers with above-average build quality. ### How does the Glass-to-Black Backsheet construction of the TITANIUM BLACK series differ from Glass-to-Glass modules? The TITANIUM BLACK series combines a front glass layer with a black electrically insulating polymer backsheet, making the module lighter and easier to handle during installation than dual-glass variants. Glass-to-Glass modules are heavier but offer greater resistance to moisture ingress and mechanical damage. For a typical pitched rooftop installation, the Glass-to-Black Backsheet construction is entirely adequate and represents a well-balanced compromise between long-term durability and installation ergonomics. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/TOPCON-Titanium-Black-47704422b6b3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +2.6 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Lighter, +2.4 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +2.3 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Lighter, +2.1 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +2.1 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +2.1 pp, +5 yr warranty | | [Emmvee E440HCM120-B](https://comparepv.com/panel/emmvee-e440hcm120-b) | 440 W | -45 W, hotter, -2.1 pp | | [Emmvee E445HCM120-B](https://comparepv.com/panel/emmvee-e445hcm120-b) | 445 W | -40 W, hotter, -1.9 pp | | [Emmvee E450HCM120-B](https://comparepv.com/panel/emmvee-e450hcm120-b) | 450 W | -35 W, hotter, -1.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +75 W, +2.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +70 W, +2.2 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +65 W, lighter, +2.0 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +55 W, +2.0 pp, +5 yr warranty | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +55 W, +2.0 pp, +5 yr warranty | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +60 W, +1.9 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +60 W, +1.8 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/emmvee-e485hcm120-bt Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
