This level of coverage is uncommon among glass-glass modules. - **N-type TOPCon half-cut cells** - N-type TOPCon technology delivers lower LID/LeTID degradation and better performance at elevated temperatures and low irradiance compared to older P-type PERC cells, translating into higher real-world energy yield, especially during summer months. - **Bifacial glass-glass construction** - The absence of a rear backsheet in favor of a glass-glass design significantly improves moisture resistance and reduces the risk of microcracks and PID, while bifaciality enables extra energy harvest from reflected light (e.g. gravel roofs, light-colored surfaces, snow) - a real advantage for carports and canopy installations that monofacial competitors cannot match. - **Fully manufactured in Germany** - Heckert Solar (Chemnitz, founded 1992) is one of the last manufacturers running a complete module production cycle in Germany, resulting in a shorter supply chain to the European market and more predictable quality control compared to manufacturers importing components from Asia. - **Aesthetic transparent design** - The transparent rear layer makes the ZEUS 1.0 Transparent series attractive for premium installations (facades, carports, canopies), where module aesthetics matter as much as electrical specs - a segment where standard opaque backsheet modules are not an option. ## Cons - **No BNEF Tier 1 status** - Heckert Solar is not listed among Bloomberg NEF Tier 1 manufacturers, which can limit bankability for projects requiring financing from international banking institutions that use this criterion - relevant for large commercial installations relying on external financing, less relevant for residential/prosumer projects. - **Lower efficiency bound trails peers** - The series' minimum efficiency is 22.5%, below comparable 455 Wp peer modules such as Sunlike Solar SKT420~455M10-108D6 (22.8%) or LEDVANCE M435~455N54LB-SF-F7 (22.77%). The highest-power variant in the ZEUS 1.0 Transparent lineup may therefore lag behind competitors' top-spec configurations in surface efficiency. ## About this series The ZEUS 1.0 Transparent series is a **bifacial glass-glass module** designed for installations where both aesthetics and maximum energy performance matter. The transparent rear layer enables full use of **bifaciality**, allowing the panel to generate additional energy from light reflected off bright surfaces, gravel roofs, or snow, meaningfully boosting overall system output compared to conventional monofacial modules. At the core of the series is **N-Type TOPCon half-cut cell technology**, which delivers lower power degradation over time and better performance under low-irradiance and elevated-temperature conditions. The glass-glass construction, free of a rear backsheet, significantly improves mechanical strength and moisture resistance, translating into a longer service life and reduced risk of microcracks or PID. This solution is aimed at investors seeking high reliability as well as designers of premium installations where a transparent, elegant module appearance matters, for example in carports, facades, or canopy structures. The ZEUS 1.0 Transparent stands out from competing products by combining aesthetics, durability, and high energy efficiency, backed by a long-term power warranty. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - Power density of 227.7 W/m² matches the \*\*TOPCon 450-500W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #2714 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### How much extra energy do the bifacial ZEUS 1.0 Transparent panels really generate? Thanks to bifacial technology and the transparent rear layer, the ZEUS 1.0 Transparent module can generate up to 25% additional energy compared to a standard monofacial panel. The actual gain depends on ground albedo — the best results come from installations above a light gravel roof, a white roofing membrane, snow cover, or a bright surface beneath a ground-mounted structure. ### How do the N-Type TOPCon cells in ZEUS 1.0 Transparent differ from classic P-Type cells? N-Type TOPCon cells show lower first-year and long-term power degradation than typical P-Type PERC cells. They also perform better at high temperatures and under low-irradiance conditions, resulting in higher real-world energy yield during cloudy periods and hot summer days. ### What warranty comes with ZEUS 1.0 Transparent panels and what does it cover? Heckert Solar provides a 30-year product warranty and a 30-year power warranty for the ZEUS 1.0 Transparent series. The product warranty covers material and workmanship defects, while the power warranty guarantees the module maintains its rated output throughout the system's operating life. ### Is the ZEUS 1.0 Transparent panel suitable for carports or glazed canopies? Yes, this is one of the series' main applications. The glass-glass construction with a transparent rear layer allows light to pass through and offers partial visibility, making ZEUS 1.0 Transparent well suited for carports, patio canopies, facades, and other installations where aesthetics and a see-through effect matter as much as energy production. ### Is the frameless glass-glass construction without a rear backsheet more durable than a standard panel? Yes. The absence of a polymer backsheet, combined with two layers of tempered glass, significantly increases module rigidity and resistance to moisture, microcracks, and PID degradation. This construction handles snow and wind loads better and carries a lower risk of delamination compared to classic modules with a polymer backsheet. ### Who manufactures ZEUS 1.0 Transparent and how long has the company been in business? The manufacturer is Heckert Solar, a German PV module producer headquartered in Chemnitz. The company designs and manufactures its panels in Germany, which matters to investors seeking modules covered by strict European quality standards and shorter supply chains compared to Asian manufacturers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/DataSheet_Zeus10_450-455Wp_EN_web-e12556b8e765.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, lighter, +1.7 pp | | [Heckert Solar ZEUS 1.1 440WP Full Black](https://comparepv.com/panel/heckert-solar-zeus-1-1-440wp-full-black) | 440 W | -15 W, lighter, -0.8 pp | | [Heckert Solar ZEUS 1.1 445W Black Frame](https://comparepv.com/panel/heckert-solar-zeus-1-1-445w-black-frame) | 445 W | -10 W, lighter, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/heckert-solar-zeus-1-0-455 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.
