Light for its output, weak in heat
The Heckert Solar NEMO® 2.0 60 M series consists of monocrystalline modules designed for installations where predictable energy production and stable performance over many years are crucial. The use of anti-reflective coated glass helps to better utilize light, even at less favorable angles, which, in Polish conditions, translates to more consistent energy generation throughout the day. The design has been optimized for durability - a robust frame and resistance to loads ensure trouble-free operation on residential rooftops and small commercial installations.
In practice, the NEMO® 2.0 60 M solves common investment challenges: limited mounting area, the need for an aesthetically pleasing appearance, and the expectation of consistent performance across the entire batch. Darker variations are also available, making it easier to match to modern roofing styles. A key feature of the series is the emphasis on quality control, repeatability, and mechanical resistance, as well as anti-reflective glass and proven monocrystalline technology - this makes it a good choice for installers and customers who simply want to install and generate energy without surprises.

Modules are produced at Heckert Solar's plant in Chemnitz, Germany. The manufacturer has held the Top-Brand-PV seal since 2015 and is ranked in the upper-premium DACH market segment — comparable to Solarwatt. European production standards translate into high parameter consistency across delivery batches, which matters for installers calculating system-level output.
The frame withstands snow loads up to 5,400 Pa and wind loads up to 2,400 Pa, fully satisfying IEC 61215 certification requirements. For Polish snow zones II–III, this provides a meaningful safety margin on pitched residential rooftops.
The series achieves clearly higher efficiency than SP Enerji SP Poly 72-cell (17.26%) and Huasun HSN-210R-B72 (15.1%) at the same 335 Wp nameplate power, reducing required roof area. Among the listed peer comparables, it trails only the SunLink LUXMAX (20.16%).
The manufacturer offers a 15-year product warranty and a 25-year linear power performance warranty — a premium-tier commitment for residential prosumer and small commercial systems. At the series' market launch in 2018, these warranty terms were among the best-in-class.
The NEMO® 2.0 60 M series ended production in 2023. This means limited availability of new modules on the primary market, practical inability to source matching panels for system expansion, and potential difficulties with warranty replacements over the longer service horizon.
The module uses 60 full PERC cells rather than the modern half-cut topology (120 cells), which became the market standard around 2020. Full cells produce higher resistive losses and greater sensitivity to partial shading, reducing yield on installations with non-uniform shading from chimneys or roof windows.
PERC cells exhibit a temperature coefficient of Pmax at –0.41 %/°C, while modern TOPCon modules achieve –0.28 to –0.35 %/°C — a meaningful difference on hot summer days. PERC efficiency tops out at ~20%, whereas TOPCon/HJT already reaches 22–24.5%, making a 2025–2026 purchase a choice of a technology with no further development roadmap.
- At 19.9% efficiency, this panel is on par with typical PERC 0-400W modules
- Power density of 199.4 W/m² packs 5.0 W/m² more into the same footprint vs PERC 0-400W median (194.4 W/m²)
- At -0.38%/°C, loses 0.02pp more power per degree than PERC 0-400W median (-0.36%/°C)
- 18.3 kg weight - 2.2 kg lighter than PERC 0-400W median (20.5 kg), reducing installation effort
- #12331 for efficiency, #13397 for temperature performance out of 14005 panels
