Warranty claims represent just 0.0002% of revenue, confirming real-world manufacturing quality rather than merely stated compliance. - **Transparent Backsheet: Bifacial Gain Without Glass-Glass Weight** - The transparent-backsheet architecture is approximately 25–30% lighter than a full glass-glass construction, simplifying installation and reducing roof load. The retained bifaciality factor of ~80% (±5%) enables effective albedo utilization on light-colored rooftops, carports, and ground-mount systems without imposing structural overload. - **30-Year Linear Power Warranty** - The manufacturer provides a 30-year linear power output warranty — five years longer than the 25-year standard offered by many peer comparables in this power class. For residential prosumer and commercial installations alike, this means the warranty coverage spans the full project financing horizon. - **N-Type TOPCon: No LID and Superior Thermal Stability** - N-type TOPCon cells exhibit no Light-Induced Degradation (LID) — a known limitation of P-type PERC — and a lower temperature coefficient of power (typically around -0.30%/°C vs. -0.35%/°C for PERC). This translates into measurably higher energy yield on hot days and lower annual degradation across the full 30-year service life. ## Cons - **No BNEF Tier-1 Status – Bankability Constraint** - Emmvee does not appear on the BNEF Bankable Manufacturers (Tier-1) list, whereas its direct peer JA Solar (Deep Blue 4.0) holds that designation. In projects financed by commercial banks or infrastructure funds, the absence of bankability may result in module rejection or requirements for additional financial guarantees, limiting the series' applicability in utility-scale and C&I segments with external financing. - **Transparent Backsheet: Long-Term UV Degradation Risk** - Research published in Solar Energy Materials (ScienceDirect, 2023) indicates that transparent backsheets exhibit higher levels of UV photochemical degradation over a 25–30 year horizon compared to tempered rear glass in a glass-glass configuration. Given Emmvee's stated 30-year power warranty, the difference in long-term rear encapsulant durability may carry operational significance, particularly in high-irradiance climates. ## About this series The Emmvee Titanium Clear (N-type bifacial glass to transparent backsheet) series are modules designed for maximum energy yield, where every square meter counts. The use of **N-type TOPCon cells** results in high efficiency over a long period, as well as stable performance under real operating conditions. A key feature is the **bifacial design** with a **transparent backsheet**, which better utilizes reflected light from the ground (albedo) - this is particularly important on roofs with light-colored surfaces, carports, ground-mounted installations, and elevated structures. The modules utilize **half-cut cells** and an optimized connection layout, which helps to minimize losses under partial shading and improves the overall string's performance. Furthermore, the robust glass and frame construction provides resistance to loads and varying weather conditions. Titanium Clear is suitable for investors who expect predictable yields, good performance in less sunny conditions, and the benefits of bifaciality without resorting to a heavier, full glass-glass architecture. ## Notable figures - Efficiency of 21.9% is 0.6pp below the \*\*TOPCon 550-600W\*\* median (22.4%) - At 218.7 W/m², this panel generates 5.7 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 - 27.1 kg weight - 4.1 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - #6908 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty is offered on the Emmvee Titanium Clear panels and what does it cover? Emmvee provides a 12-year product warranty on Titanium Clear modules and a 30-year linear power output warranty. This means the manufacturer guarantees that the modules will maintain a specified percentage of their original rated power (up to 580 Wp) over 30 years. This is one of the longest power output warranty periods available on the market, and it is particularly significant when calculating return on investment. ### What is the transparent backsheet in the Emmvee Titanium Clear and how does it differ from a glass-glass construction? Instead of a rear glass pane, the Titanium Clear uses a transparent backsheet film that allows light reflected from the mounting surface (albedo) to reach the rear side of the cells. Compared to the heavier glass-glass architecture, the module is lighter and easier to install, while still retaining its bifacial capability. This solution is especially well-suited for light-colored rooftops, carports, and ground-mounted systems with a reflective surface beneath. ### What is the actual bifacial gain of the Emmvee Titanium Clear panels? The bifaciality factor of the Titanium Clear modules is approximately 80%, meaning the rear side can generate up to 80% of the front-side power output given adequate ground reflectance. In practice, on ground-mounted installations with a light-colored surface or on carports, bifaciality translates into 5–15% additional annual energy yield compared to an equivalent monofacial module. ### Are the Emmvee Titanium Clear 580 Wp panels suitable for a standard pitched roof installation? Yes, the Titanium Clear modules are compatible with conventional rooftop mounting systems. It is worth noting, however, that bifaciality delivers the greatest benefit in installations with access to reflected light — for example, on roofs with a light-colored surface or in elevated racking systems. On a conventional dark roof, the module still performs efficiently thanks to its N-type TOPCon technology, which provides strong performance under diffuse irradiance conditions. ### Does the N-type TOPCon technology in the Emmvee Titanium Clear perform better on cloudy days than standard panels? Yes, N-type TOPCon cells exhibit a lower temperature coefficient and superior low-light response compared to the more common P-type PERC modules. This results in higher energy yields under overcast conditions, during early morning hours, and in the late afternoon. The combination of this technology with half-cut cells further reduces losses under partial shading conditions. ### Is Emmvee a reputable manufacturer and are the Titanium Clear panels available in Poland? Emmvee Photovoltaic Power is an Indian manufacturer headquartered in Bengaluru, in operation since 2007. The company does not appear on the Bloomberg NEF Tier 1 list; however, it operates its own manufacturing facilities and is actively expanding its exports to Europe. The Titanium Clear series modules are currently active in the product lineup — they have not been discontinued — and are available through European distributors, although availability in Poland should be confirmed directly with the supplier on a case-by-case basis. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/topcon-titanium-clear-d3a32024c444.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -20 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.3 pp | | [Emmvee E530HCM144-B](https://comparepv.com/panel/emmvee-e530hcm144-b) | 530 W | Hotter, -1.4 pp, -5 yr warranty | | [Emmvee E535HCM144-B](https://comparepv.com/panel/emmvee-e535hcm144-b) | 535 W | Hotter, -1.2 pp, -5 yr warranty | | [Emmvee E540HCM144-B](https://comparepv.com/panel/emmvee-e540hcm144-b) | 540 W | Hotter, -1.0 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +75 W, cooler, +2.9 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +65 W, heavier, +2.5 pp | --- Source: https://comparepv.com/panel/emmvee-es65hcbt144-t Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
