This opens up installations on flat and pitched roofs with structural load limits below 15 kg/m², where framed PERC/TOPCon modules are not viable without costly structural reinforcement. - **9 mm Frameless Composite Construction** - The absence of an aluminum frame and a profile of just 9 mm (vs. 35–40 mm for standard modules) reduces installation time, eliminates the risk of galvanic corrosion at frame joints, and lowers shipping volume — particularly valuable in commercial retrofit projects where labor costs represent a significant share of the overall installation budget. - **Half-Cut Cells + SMBB: Shade Resilience** - The half-cut cell layout combined with Small Multi-Busbar (SMBB) technology reduces resistive losses at interconnects and limits the impact of partial shading on the full string. In urban environments with chimneys and dormers, this translates into a tangible operational advantage over full-cell modules without SMBB. - **Low NMOT of 43°C** - The module's Nominal Module Operating Temperature is 43°C, compared to 45–47°C typical of standard PERC modules. The lower operating point directly reduces temperature-related power losses (Pmax temperature coefficient of approx. −0.35%/°C), resulting in higher energy yield on hot days. - **BloombergNEF Tier-1 Status (since 2023)** - DAS Solar was included on the BloombergNEF Tier-1 list in 2023, confirming its eligibility for non-recourse project financing by lenders. For commercial investors and residential customers utilizing loan financing, Tier-1 BNEF status is a prerequisite when selecting a module supplier. ## Cons - **Efficiency 3–4 Percentage Points Below N-Type Competitors** - The efficiency range of 19.9–20.8% falls noticeably short of peer comparables in the same power class: JA Solar JAM54D40 LB and Astronergy ASTRO N7s 2.0 achieve 23.8%, and the Longi Hi-MO X10 reaches 23.3%. On a standard roof without weight constraints, this means approximately 15–18% more DAS-LH132PA modules would need to be installed to deliver the same system output. - **PERC Technology vs. N-Type TOPCon in Competing Products** - P-type PERC cells exhibit higher Light-Induced Degradation (LID) and do not offer the benefits of bifaciality. Peer comparables from JA Solar, Astronergy, and Longi are based on N-type architecture, where LID is near zero and the linear annual degradation rate is approximately 0.05–0.1 percentage points lower — a measurable difference in cumulative energy yield over a 25-year power warranty period. - **Limited Manufacturer Track Record** - DAS Solar was founded in 2018 and only achieved BloombergNEF Tier-1 status in 2023. Against a 25-year performance warranty, the manufacturer's operational history is significantly shorter than that of JA Solar (active since the late 1990s) or Longi Solar (since 2000), which constitutes a risk factor when assessing the long-term bankability of projects. ## About this series The DAS Solar DAS-LH132PA series was designed for installations where construction constraints and installation speed are key factors. These are **ultralightweight, frameless composite modules**, making them easier to handle, safer to install, and more efficiently logistically managed - especially on roofs with lower load capacity, during renovations, and in situations where every minute of the team's work counts. The construction, based on **half-cell technology** and **SMBB**, improves performance under partial shading and minimizes losses at microjunctions, resulting in a more stable yield under real-world conditions. Furthermore, the low operating temperature level helps maintain efficiency during summer, and **excellent performance under low-light conditions** helps recover energy in the morning, evening, and on cloudy days - precisely when many standard modules significantly reduce output. The DAS-LH132PA is an excellent choice for roof installations (including those on lightweight roofing systems), commercial properties with load restrictions, and projects where installation costs and logistics are prioritized, not just catalog parameters. ## Notable figures - Module efficiency of 19.9% is 0.9pp below average for \*\*PERC 450-500W\*\* panels (median: 20.8%) - 186.8 W/m² power density is 21.7 W/m² below \*\*PERC 450-500W\*\* median (208.5 W/m²) - requires larger installation area - Temperature coefficient of -0.34%/°C matches the \*\*PERC 450-500W\*\* median - At 10.2 kg, this panel is 14.3 kg lighter than \*\*PERC 450-500W\*\* median (24.5 kg) - easier handling during installation - In the top 88% for efficiency among all PERC panels ## Questions ### How much does the DAS Solar DAS-LH132PA panel weigh, and is it suitable for low load-bearing roofs? The DAS-LH132PA series consists of ultra-lightweight, frameless composite modules with a thickness of only 9 mm. By using a composite backsheet instead of a conventional aluminum frame, these panels are significantly lighter than standard modules in the same power class. This makes them particularly well-suited for roofs with limited structural capacity, such as older buildings, lightweight roofing systems, or structures that have undergone retrofitting. ### What warranty is offered on the DAS Solar DAS-LH132PA panels? The manufacturer provides a 12-year product warranty on the DAS-LH132PA series. In addition, a 25-year linear power output warranty applies — throughout this period, the module is guaranteed to retain the percentage of nominal power specified in the datasheet. Both warranties are issued by DAS Solar, a manufacturer ranked on the Bloomberg NEF Tier 1 list. ### Do the DAS-LH132PA panels perform well on cloudy days and under low-irradiance conditions? Yes. The DAS-LH132PA series is characterized by excellent low-light performance. This means the modules recover energy more efficiently during morning and evening hours and under overcast conditions compared to standard panels. Additionally, a low Nominal Module Operating Temperature (NMOT of approximately 43 °C) helps maintain high efficiency on hot summer days. ### What cell technology is used in the DAS-LH132PA series, and what does it mean for performance? The DAS-LH132PA series employs PERC cells in a half-cut format combined with SMBB (Super Multi Busbar) interconnection technology. Splitting the cells in half reduces internal resistance and improves tolerance to partial shading, while SMBB minimizes resistive losses at the cell interconnections. The result is a more stable and higher energy yield under real-world operating conditions, particularly when roof irradiance is non-uniform. ### What is the maximum power output of the DAS Solar DAS-LH132PA module, and which variant should I choose? The DAS-LH132PA series is available in a power range from 455 Wp to 475 Wp. The top-tier variant achieves 475 Wp with an efficiency of approximately 19.9%. For most residential and commercial installations, selecting the highest available power variant is advisable — it increases annual energy yield without requiring additional panels to be installed, which is especially important when roof space is limited. ### Does the frameless design of the DAS-LH132PA panels complicate installation, and is it compatible with standard mounting systems? Frameless composite modules require dedicated clamps and mounting hardware designed specifically for frameless installation — they are not directly compatible with the standard mid-clamps and end-clamps used with aluminum-framed modules. However, major racking and mounting system manufacturers (e.g., K2 Systems, Schletter, Esdec) offer appropriate mounting kits for frameless panels. It is advisable to discuss this with the installer before ordering the mounting structure in order to avoid delays on-site. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/7-7cc735adcb25.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, heavier, +4.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, heavier, +4.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, heavier, +4.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, heavier, +4.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, heavier, +4.6 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | Cooler, heavier, +4.6 pp | | [DAS Solar DAS-LH132PA-460W](https://comparepv.com/panel/das-solar-das-lh132pa-460w) | 460 W | +0.2 pp | | [DAS Solar DAS-LH132PA-465W](https://comparepv.com/panel/das-solar-das-lh132pa-465w) | 465 W | +10 W, +0.4 pp | | [DAS Solar DAS-LH132PA-470W](https://comparepv.com/panel/das-solar-das-lh132pa-470w) | 470 W | +15 W, +0.7 pp | | [DAS Solar DAS-LH132PA-475W](https://comparepv.com/panel/das-solar-das-lh132pa-475w) | 475 W | +20 W, +0.9 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +135 W, 16 kg heavier, +3.9 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +130 W, 16 kg heavier, +3.7 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +125 W, 16 kg heavier, +3.6 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +125 W, 16 kg heavier, +3.5 pp | --- Source: https://comparepv.com/panel/das-solar-das-lh132pa-455w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
