**Made in Germany, lead- and PFAS-free** - APOLLON 2.0 is manufactured in Germany under strict quality standards, free of lead and PFAS — a rare feature among TOPCon modules on the European market, which is dominated by Asian-made products. - **30-year product and power warranty** - The manufacturer offers 30 years of both product and linear power warranty — significantly above the market standard of 12-15 years for product warranty and 25 years for power warranty, reducing long-term investment risk. - **Shingle matrix architecture without visible busbars** - The uniform shingle matrix structure eliminates gaps between cells, reduces resistive losses, and improves partial-shading behavior, resulting in more stable year-round yields and a sleek, uniform aesthetic. - **Glass-glass construction with bifacial technology** - The double-glass build increases mechanical durability and panel lifespan while enabling bifacial energy harvest from light reflected off roofs or ground surfaces — typical bifacial gain ranges 5-15% depending on surface albedo. - **Efficiency competitive with segment leaders** - Efficiency up to 23.0% places APOLLON 2.0 close to the top of the TOPCon segment alongside SunKean SKT440~460M12-96D4 and Phono Solar Draco (both 23.02%), outperforming Axitec AXIbiperfect GR WB (22.54%) at the same 460 Wp max power. ## Cons - **Efficiency slightly below peer group leaders** - Maximum efficiency of 23.0% is marginally lower than SunKean SKT440~460M12-96D4 and Phono Solar Draco (23.02%) at the identical 460 Wp max power — a marginal gap, but it puts APOLLON 2.0 at a disadvantage in head-to-head spec comparisons. - **No long-term field data yet** - The series launched in 2026, so there is no multi-year real-world degradation and durability data available, unlike TOPCon designs that have been on the market since 2022-2023. - **German manufacturing price premium** - Manufacturing in Germany, unlike the mass production of Asian Tier-1 makers (e.g., SunKean, Phono Solar), typically carries a higher cost per Wp, which may limit price competitiveness in CAPEX-sensitive projects. ## About this series APOLLON 2.0 is a next-generation bifacial photovoltaic module designed for rooftop installations with high aesthetic and performance demands. The series is built on **N-Type TOPCon** cells arranged in an innovative, uniform shingle matrix structure that eliminates visible gaps between cells, giving the panel a sleek, seamless appearance. This architecture reduces resistive losses and improves the module's behavior under partial shading conditions, resulting in more consistent energy yields throughout the year. The **glass-glass** construction increases mechanical durability and extends the panel's service life, while also serving as the foundation for two-sided energy harvesting through **bifacial** technology, which also captures light reflected from the roof or ground surface. APOLLON 2.0 is aimed at investors seeking a premium solution for roofs with limited surface area, where both aesthetics and maximizing power output per square meter matter. The panel is **manufactured in Germany** in accordance with strict quality standards, free of lead and PFAS, making it an attractive choice for customers who also value environmental considerations and component origin. ## Notable figures - At 23.0% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - Power density of 230.2 W/m² packs 5.0 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - #1919 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### How does APOLLON 2.0 differ from standard TOPCon panels? The key difference is the shingled matrix cell layout - in APOLLON 2.0, N-Type TOPCon cells are arranged with no visible gaps, creating a uniform surface and better current distribution. This reduces resistive losses and improves partial shading tolerance compared to standard modules with a classic cell layout and visible busbars. ### Does the bifacial technology in APOLLON 2.0 actually increase energy yield? Yes, the glass-glass construction lets the rear side of the panel capture light reflected from the roof, bright surfaces, or surroundings, adding extra energy production compared to a monofacial module. The actual gain depends on roof color, mounting angle, and height above the surface, but typical rooftop installations can expect an additional few percent of yield. ### What warranty does APOLLON 2.0 come with and what does it cover? Heckert Solar provides a 30-year product warranty and a 30-year power performance warranty on the APOLLON 2.0 module. This means the manufacturer commits both to repairing or replacing a defective panel and to maintaining a specified power output level over that entire period, making it one of the longest warranty terms currently available in the PV module market. ### Is APOLLON 2.0 suitable for a roof with limited surface area? Yes, this is one of the series' main use cases. With power up to 460 Wp and high module efficiency, APOLLON 2.0 delivers more energy per square meter than lower-power panels. It's recommended for installers with limited roof area who want to maximize system capacity without expanding the roof surface. ### Is APOLLON 2.0 manufactured in Europe or imported from Asia? APOLLON 2.0 is manufactured in Germany at the Heckert Solar factory, following strict European quality standards. Production is free of lead and PFAS, which matters both for the panel's environmental footprint and for customers who care about component origin and a shorter supply chain compared to modules imported from outside Europe. ### Does APOLLON 2.0 look good on a residential roof? Yes, the uniform shingled matrix structure eliminates visible gaps between cells, giving the panel a smooth, seamless appearance instead of the typical cell grid pattern. This is especially valued for installations on single-family homes, where the roof's visual appearance matters to the homeowner. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/202603_Datasheet_Apollon20-5e92f94ffaa9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, cooler, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +1.5 pp | | [Heckert Solar ZEUS 1.1 440WP Full Black](https://comparepv.com/panel/heckert-solar-zeus-1-1-440wp-full-black) | 440 W | -20 W, lighter, -1.0 pp | | [Heckert Solar ZEUS 1.1 445W Black Frame](https://comparepv.com/panel/heckert-solar-zeus-1-1-445w-black-frame) | 445 W | -15 W, lighter, -0.7 pp | --- Source: https://comparepv.com/panel/heckert-solar-apollon-2-0-460wp Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
