At a typical summer module operating temperature of 65°C, this difference translates to approximately 2% higher energy yield compared to PERC under full irradiance conditions. Additionally, N-type technology eliminates the first-year LID degradation issue. - **Kiwa PVEL PQP 2024 – Top Performer in All 7 Categories** - Emmvee is the only Indian manufacturer and one of only four worldwide to achieve Top Performer status across all seven categories of the Kiwa PVEL Product Quality Program 2024 (including PID, LeTID, DML, and thermal cycling). A warranty claim rate of just 0.0002% of revenue independently confirms the real-world manufacturing quality. - **~80% Bifaciality + Glass-to-Glass Construction** - A rear glass with approximately 95% transmittance and bifaciality of 80% (±5%) enable rear-side energy gains of 10–25% in carport or ground-mount installations over high-albedo surfaces (gravel, concrete, snow). The glass-to-glass construction simultaneously enhances mechanical resilience and eliminates backsheet degradation, a known failure mode in conventional foil-backed modules. - **30-Year Linear Warranty, 0.40%/Year Degradation** - The manufacturer guarantees a maximum of 2% degradation in year one and no more than 0.40%/year in years 2–30, yielding ≥87.4% of nominal power output after 30 years. The peer-comparable JA Solar DEEP BLUE 4.0 offers an equivalent performance warranty level, but the TITANIUM CLEAR series outperforms modules with the shorter 25-year warranties prevalent in the market. - **Premium-Class Mechanical Durability** - Certified load-bearing capacity of 5,400 Pa (combined snow and wind) and hail resistance for Ø24 mm hailstones at an impact velocity of 83 km/h are a direct result of the dual-glass 2+2 mm construction. The IP68-rated junction box with a three-part design minimizes moisture ingress risk in carport and BIPV applications. ## Cons - **No BNEF Tier-1 Status (Bankability)** - Emmvee does not appear on the BNEF Tier-1 bankable manufacturer lists (tier\_1\_bankable: false in the supplied data context), which represents a significant barrier for commercial projects financed on a non-recourse basis. Banks and infrastructure funds routinely require modules from BNEF Tier-1 manufacturers as a condition of project financing, effectively limiting the TITANIUM CLEAR series to prosumer and smaller commercial installations funded with equity or corporate balance sheets. - **Limited Service Network Outside Asian Markets** - Emmvee's headquarters and logistics centers are located in Bengaluru, India, with no confirmed European buffer warehouses or authorized service partners in Poland or the broader CEE region. In the event of warranty claims, this may result in longer resolution times compared to manufacturers with established European distribution centers — such as JA Solar, which operates a European office in Germany. ## About this series The Emmvee TITANIUM CLEAR series redefines performance standards through the use of advanced **bifacial monocrystalline cell** technology, which allows for efficient energy generation from both sides of the module. The use of a transparent backsheet ensures that these panels perform exceptionally well in diffused light conditions, which directly translates into significantly higher annual yields compared to traditional, monofacial solutions. A key element of the design is **Half-Cut cell technology** combined with a modern multi-busbar system, which effectively minimizes resistance losses and increases overall resistance to micro-cracks. These models solve the problem of limited installation space, offering investors maximum power density from every square meter of roof or ground. Thanks to its unique aesthetics and partial light transmittance, the TITANIUM CLEAR series is an ideal choice for **modern carport installations** and building-integrated systems where design must go hand-in-hand with high functionality. The solid frame construction ensures exceptional mechanical stability, which clearly distinguishes these modules from lighter competitors and guarantees full reliability in harsh weather conditions. This solution is dedicated to conscious users for whom the priority is **maximizing yields per unit of area** and stable energy production throughout the day. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - 228.4 W/m² power density - 4.0 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - At 26.0 kg, this panel is 5.2 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg) - easier handling during installation - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### Are Emmvee TITANIUM CLEAR panels suitable for carport installations and BIPV systems? Yes, the TITANIUM CLEAR series was specifically designed with these applications in mind. The module's transparent backsheet allows a portion of light to pass through, which is essential in carport canopies and building-integrated photovoltaic (BIPV) installations where aesthetics and partial light transmittance are required. The bifacial TOPCon cells additionally generate energy from irradiance reflected off the ground surface, increasing annual energy yield without the need to expand the installation area. ### What warranty is offered on Emmvee TITANIUM CLEAR panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means that over three decades, the modules must maintain the percentage of nominal output power specified by Emmvee. It is worth noting that Emmvee records warranty claims at a rate of just 0.0002% of revenue, which is a testament to the exceptionally high reliability of their manufacturing process. ### What advantages does TOPCon technology offer over standard PERC cells in the TITANIUM CLEAR series? TOPCon (Tunnel Oxide Passivated Contact) cells are an N-type technology that delivers higher conversion efficiency, a lower temperature coefficient, and reduced degradation from Light-Induced Degradation (LID) compared to conventional PERC cells. In practice, this translates to better energy production on hot summer days and a slower decline in power output over the full 30-year service life of the installation. The TITANIUM CLEAR series leverages this technology in combination with a bifacial design, further increasing annual energy yield. ### What is the maximum power output of the Emmvee TITANIUM CLEAR module, and is it sufficient for a typical home? The top model in the series reaches a peak power of 580 Wp. For a typical home with an annual electricity consumption of approximately 3,500 kWh, 8–10 of these modules (approximately 4.6–5.8 kWp) are generally sufficient, occupying significantly less roof area than older, lower-power panels. The high power density of the TITANIUM CLEAR series is particularly advantageous where available mounting space is limited. ### Is Emmvee a reliable manufacturer even though it does not appear on the Tier 1 list? Emmvee is an Indian manufacturer with over 30 years of history and a current production capacity exceeding 7.8 GW. While the company does not appear on the widely cited Tier 1 lists — which are primarily a financial ranking rather than a quality assessment — Emmvee is the only Indian manufacturer to have received top recognition in all seven reliability test categories of the Kiwa PVEL PQP scorecard in 2024, placing it among the top four module manufacturers in the world in terms of durability and quality. ### How does the bifaciality of TITANIUM CLEAR panels translate into real-world energy gains? Bifacial modules with a transparent backsheet capture not only direct irradiance from the front side but also light reflected from the ground or surrounding surfaces — the so-called albedo component. In carport installations over light-colored pavement, on roofs with a white membrane, or in ground-mounted systems over bright substrates, the rear-side gain can range from 5% to as much as 25% compared to a monofacial module. The half-cut cell technology and multi-busbar current collection design further reduce resistive losses, boosting the overall annual energy yield. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/144-Half-cut-cell-transparent-back-sheet-51c71dbc74b0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, +2.0 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Heavier, +1.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Lighter, +1.6 pp, +5 yr warranty | | [Emmvee E530HCM144-B](https://comparepv.com/panel/emmvee-e530hcm144-b) | 530 W | -60 W, hotter, -2.3 pp | | [Emmvee E535HCM144-B](https://comparepv.com/panel/emmvee-e535hcm144-b) | 535 W | -55 W, hotter, -2.1 pp | | [Emmvee E540HCM144-B](https://comparepv.com/panel/emmvee-e540hcm144-b) | 540 W | -50 W, hotter, -1.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/emmvee-e590hcbt144-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.
