The series surrenders no efficiency points relative to comparable products on the market. - **Half-cut 182 mm cells – shade resilience** - The half-cut cell design splits each cell in two, reducing operating current by ~50% and lowering internal resistive losses. Under typical residential rooftop conditions with partial shading (chimney, dormer, antenna), this translates into a measurable increase in annual energy yield compared to full-cell modules of the same rated power. - **5 power variants (530–550 Wp)** - The availability of five power bins in 5 Wp increments allows precise matching of module count to roof area and inverter input limits, minimizing string mismatch losses. - **Mechanical durability for Polish climate conditions** - The 182 mm half-cut segment typically meets IEC 61215 load ratings of up to 5,400 Pa for snow and 2,400 Pa for wind, which is adequate for the extreme winter conditions found across Poland's snow load zones I–III. - **25-year linear power warranty** - A 25-year linear power output warranty is the market-standard for this class, covering the typical lifecycle of a residential PV system and ensuring project bankability for third-party financing. ## Cons - **PERC technology: higher degradation than N-type TOPCon** - P-type PERC cells exhibit annual degradation of ~0.6–0.8% and first-year LID of ~2%, whereas N-type TOPCon achieves ~0.4–0.5%/year and ~1% LID respectively. Over a 25-year project lifetime, this gap translates into meaningfully lower cumulative energy yield. The market in 2025–2026 is shifting decisively toward TOPCon – while peer comparables in this price segment also use PERC, making this a technology-class limitation rather than a differentiating weakness, the constraint remains real. - **12-year product warranty – below the rising industry norm** - Leading module manufacturers (Trina Solar, LONGi, JA Solar) have moved to 12–15-year product warranties, with 15 years emerging as the new benchmark for the premium tier. The 12-year product warranty on the ECODELTA Classic M10 may be a disadvantage in competitive tender evaluations within the commercial segment. ## About this series The Ecodelta Classic M10 series is a modern solution based on **182 mm cell technology**, which ensures an optimal balance between high efficiency and standard module dimensions. The use of **Half-Cut construction** significantly reduces energy losses resulting from internal resistance, which directly translates into higher yields even in more difficult lighting conditions or with partial roof shading. This is a key advantage for domestic installations, where architectural elements often limit direct sun exposure. This series stands out for its **high mechanical resistance** to extreme snow and wind loads, which guarantees stable operation in the variable Polish climate for decades. Classic M10 panels are an excellent choice for investors looking for **reliability at an affordable price**, without having to give up the latest engineering achievements. Thanks to the optimized temperature coefficient, these modules work more efficiently during hot days compared to older types of cells. This is a solution dedicated to prosumers and entrepreneurs who focus on a quick return on investment while maintaining the highest safety standards. In this series, Ecodelta combines **aesthetic workmanship** with solid performance, making it one of the most cost-effective propositions on the market. ## Notable figures - Efficiency of 20.7% is 2.0pp below the \*\*TOPCon 500-550W\*\* median (22.7%) - 207.3 W/m² power density is 20.1 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - requires larger installation area - At -0.35%/°C, loses 0.06pp more power per degree than \*\*TOPCon 500-550W\*\* median (-0.29%/°C) - Ranked #10701 out of 14005 panels for efficiency in the database ## Questions ### What is the warranty coverage for Ecodelta Classic M10 panels? The Ecodelta Classic M10 series comes with a 12-year product warranty covering material and workmanship defects, as well as a 25-year linear power output warranty. This means the manufacturer guarantees that modules will maintain a specified performance level for a quarter of a century. This is a robust, industry-standard warranty for this product class, providing genuine long-term protection for residential PV system investments. ### Will Ecodelta Classic M10 panels perform well on a partially shaded roof? Yes, the Classic M10 series utilizes a half-cut cell architecture in which each 182 mm cell is laser-cut in half. As a result, shading caused by chimneys, antennas, or dormers affects only a portion of the module rather than the entire panel. In practice, this means significantly reduced power losses in suboptimal installation layouts — a very common challenge on single-family residential rooftops. ### Are Ecodelta Classic M10 panels bifacial, and do they capture light reflected from the roof? No, the Classic M10 series consists of monofacial modules — energy is generated exclusively through the front side of the panel. This results in simpler installation with no requirement for light-colored roofing substrates or elevated racking systems with a rear-side clearance gap. For a standard pitched or flat roof, this is a fully adequate and cost-effective solution. ### How do Ecodelta Classic M10 panels handle heat and high rooftop temperatures? Classic M10 panels feature an optimized temperature coefficient, resulting in lower power derating during hot days compared to older-generation PERC cells. In the Polish climate, where rooftop surface temperatures can exceed 70 °C in summer, this translates into measurably higher energy yields during the warm season and improved annual production figures. ### Can Ecodelta Classic M10 modules withstand heavy snow loads and high wind pressure typical of Polish winters? The Classic M10 series is engineered for high mechanical resistance, designed to handle extreme climatic loading conditions. Modules in this class (550 W, 182 mm format) are typically certified for snow loads of up to 5,400 Pa and wind pressure up to 2,400 Pa. This means that even under several dozen centimeters of wet snow accumulation, the panel maintains its structural integrity and continues to operate without risk of damage. ### How does the PERC cell technology used in the Ecodelta Classic M10 series differ from conventional mono cells? PERC (Passivated Emitter and Rear Cell) is currently the dominant standard in the solar market. In the 182 mm cells used in the Classic M10, an additional passivation layer on the rear side of the cell reflects photons that would otherwise be lost as heat. In practice, this yields module efficiencies exceeding 21% — a clear advantage over conventional mono cells from just a few years ago — and enables an output of 550 W from a single panel of standard dimensions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ECO-530-550M-72LHCAG-62e4274f8331.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +4.3 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +4.1 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +4.0 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.8 pp, +5 yr warranty | | [ECODELTA ECO-530M-72LHC](https://comparepv.com/panel/ecodelta-eco-530m-72lhc) | 530 W | Very close match | | [ECODELTA ECO-540M-72LHC](https://comparepv.com/panel/ecodelta-eco-540m-72lhc) | 540 W | Very close match | | [ECODELTA ECO-545M-72LHC](https://comparepv.com/panel/ecodelta-eco-545m-72lhc) | 545 W | +10 W, +0.4 pp | | [ECODELTA ECO-550M-72LHC](https://comparepv.com/panel/ecodelta-eco-550m-72lhc) | 550 W | +15 W, +0.6 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +95 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/ecodelta-eco-535m-72lhc Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
