This translates to meaningfully higher energy yield in summer months, when module temperatures regularly exceed 50–60°C. - **Kiwa PVEL PQP 2024 Top Performer** - Emmvee is the only Indian manufacturer to achieve Top Performer status across all seven test categories in the Kiwa PVEL Reliability Scorecard 2024, placing it among only four companies worldwide to reach that distinction. This independent validation of module durability carries significant weight in risk assessments conducted by insurers and project finance lenders. - **Up to 22.45% efficiency – segment-leading performance** - The peak module efficiency of 22.45% matches the EGing PV STAR Pro (22.45%) directly and falls only marginally short of the JA Solar Deep Blue 4.0 (22.5%), placing the series at the very top of the competitive set reviewed. Higher efficiency means less roof area is required to achieve the same installed capacity. - **25-year linear power warranty with minimum 89.4% output** - The manufacturer guarantees at least 89.4% of nominal power output after 25 years of operation. The industry median for modules in this class is approximately 84.8–87.4% at year 25, making Emmvee's warranty terms among the more favorable available at this price point. - **Glass-to-white backsheet construction – reduced operating temperature** - The white backsheet reflects a portion of infrared radiation, reducing module operating temperature by approximately 2–4°C compared to black backsheets under peak conditions. This effect is especially relevant on dark roofing materials and complements the inherently low temperature coefficient of the TOPCon cells. ## Cons - **Not listed as a BNEF Tier-1 bankable manufacturer** - Emmvee does not appear on the BNEF Tier-1 bankable manufacturers list (as of Q1 2026), whereas direct competitors such as JA Solar hold that status. In practice, this may complicate or increase the cost of project finance for commercial and utility-scale PV installations, where lenders typically require modules sourced from a bankable manufacturer as a standard condition of financing. ## About this series The Emmvee Titanium White series consists of N-type TOPCon modules with a 144-cell configuration, designed for high efficiency and stable performance in real-world rooftop and commercial installations. A key advantage is the **glass-to-white backsheet** design, which minimizes heat buildup and supports long-term reliability, while also facilitating aesthetically pleasing integration with light-colored roofs. The use of **N-type TOPCon cells** helps reduce losses and maintain better performance at high temperatures and under less intense sunlight. The **half-cut (cut-cell)** configuration improves resistance to partial shading and reduces the risk of noticeable power output reductions when shadows from chimneys or trees "cut through" the module. The entire system is complemented by **anti-reflective coated glass**, which enhances effective light collection during the day. Titanium White is a good choice for investors who expect predictable energy production and durability without compromising the appearance of their installations. ## Notable figures - At 22.4% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 224.4 W/m² matches the \*\*TOPCon 550-600W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 26.0 kg weight - 5.2 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - #4620 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output and module efficiency of the Emmvee Titanium White series? The Emmvee Titanium White series delivers up to 580 Wp with a module efficiency of up to 22.45%. The panel dimensions are 2278×1134×35 mm and the weight is approximately 26 kg. This means that on a typical pitched roof, a relatively high power output can be achieved with a limited number of modules — which is particularly important wherever available roof space is constrained. ### What warranty coverage applies to Emmvee Titanium White panels? The manufacturer provides a 12-year product warranty covering physical defects and material faults, along with a 25-year linear power output warranty. After 25 years, the panel is guaranteed to retain at least 89.4% of its rated nominal power. It is advisable to verify the warranty claim handling conditions in your country, as Emmvee is an Indian manufacturer not currently listed on Tier 1 rankings, meaning warranty service depends on the local distributor. ### What is the difference between the Emmvee Titanium White and the Titanium Duo series from the same manufacturer? The key difference lies in the rear surface construction. The Titanium White features a white polymer backsheet, making it a monofacial module — it harvests light from the front side only. The Titanium Duo is a bifacial glass-glass module that additionally captures energy reflected from the ground or mounting surface. The Titanium White is lighter and easier to install on pitched roofs, while the Duo performs better in ground-mount systems or flat-roof installations with a highly reflective surface beneath. ### Do Emmvee Titanium White panels perform well in summer when rooftop temperatures rise significantly? Yes. The N-type TOPCon technology features a low power temperature coefficient of approximately -0.29%/°C, which means smaller output losses at high temperatures compared to older P-type cells. Additionally, the white backsheet reflects a portion of thermal radiation, helping to reduce module operating temperature. In the context of a temperate climate, the benefit is most noticeable on hot summer days; however, this is not a cryogenic technology — at extreme temperatures, some power losses will always occur. ### Are Emmvee Titanium White panels suitable for a pitched roof with partial shading from a chimney or antenna? Largely yes. The 144 half-cut cell layout divides the module into two independent electrical circuits — shade falling on one half of the panel does not suppress the output of the other half as severely as it would in conventional full-cell modules. This does not eliminate shading losses entirely, but it significantly reduces them. For heavily shaded roofs, it is worth considering the addition of power optimizers or microinverters. ### Where is Emmvee based, and is it a proven solar panel manufacturer? Emmvee is an Indian manufacturer headquartered in Bangalore that has been active in the solar panel market since the 1990s. The company does not currently appear on Tier 1 module manufacturer lists (e.g., Bloomberg NEF), which does not necessarily indicate poor quality, but is worth factoring in when arranging project financing or insurance — some financial institutions and insurers require modules from Tier 1-listed manufacturers. Before purchasing, it is advisable to confirm warranty service terms and local support availability with the distributor. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/topcon-titanium-white-3568381c44cd.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +2.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +2.2 pp, +5 yr warranty | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, heavier, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Lighter, +1.9 pp, +5 yr warranty | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, +1.9 pp, +5 yr warranty | | [Emmvee E530HCM144-B](https://comparepv.com/panel/emmvee-e530hcm144-b) | 530 W | -50 W, hotter, -1.9 pp | | [Emmvee E535HCM144-B](https://comparepv.com/panel/emmvee-e535hcm144-b) | 535 W | -45 W, hotter, -1.7 pp | | [Emmvee E540HCM144-B](https://comparepv.com/panel/emmvee-e540hcm144-b) | 540 W | -40 W, hotter, -1.6 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, +2.8 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, +2.6 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/emmvee-es580hcmw144-t Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
