This ensures warranty enforceability — including the 25-year power output guarantee — backed by a financially stable, globally recognized manufacturer. - **25-Year Linear Power Warranty** - Despite a short 12-year product warranty, the manufacturer guarantees a defined minimum power output level for 25 years of operation — in line with Tier-1 industry practice for modules in this power class (195–215 Wp). - **5 Power Variants, 195–215 Wp** - The series offers five wattage steps across the 195–215 Wp range, enabling precise module selection for a given roof geometry or energy balance requirement without mixing series or string configurations. - **PERC Technology — Advanced for Its Release Year** - At its 2009 launch, PERC cells represented a genuine commercial breakthrough. The rear-surface passivation dielectric layer delivered measurably higher energy yield versus the standard BSF cells that dominated mass production at the time. ## Cons - **Discontinued Series (EOL 2012)** - The 5M series was manufactured only between 2009 and 2012 and is officially discontinued. New modules for system expansion are unavailable, after-sales service support is limited, and obtaining updated certifications or documentation for new permits may be difficult. - **Low Efficiency vs. Available Alternatives** - The 15.3–16.8% efficiency range is significantly below peer comparables: MY Solar M6 reaches 19.55%, and IBC Solar 210M Split Cell hits 20.83%. Even TPL Solar P-48 (16.42%) outperforms the lower 5M variants. This translates to roughly 15–25% more roof or ground area required to achieve the same installed capacity. - **Short Product Warranty — 12 Years** - The product workmanship warranty is only 12 years, compared to the current Tier-1 industry standard of 25 years (including newer JA Solar series). Any mechanical failure, delamination, or frame defect occurring after year 12 carries no manufacturer warranty coverage. - **Legacy p-Type PERC vs. n-Type TOPCon/HJT** - The p-type PERC cells used in 2009–2012 production exhibit higher LID (Light-Induced Degradation) and weaker low-irradiance performance compared to modern n-type TOPCon or HJT cells. For systems already operating for over a decade, this results in a meaningfully lower annual energy yield than current-generation alternatives. ## About this series The JA Solar 5M series consists of modules designed to maximize energy yield under real-world conditions, including lower sunlight, cloudy weather, and variable weather. The use of advanced n-type silicon cells in a TOPCon architecture, along with a refined connection design, allows the panels to efficiently utilize light and operate stably in demanding installations. In practice, this translates to **higher energy production** from the same roof or ground area, as well as **improved investment payback** over the entire lifespan of the installation. Compared to many competing solutions, the 5M series offers **low power degradation**, which facilitates long-term cost savings and ensures high yields for years to come. Furthermore, thoughtful material and construction solutions support **high durability and reliability** in operating conditions. This series is particularly well-suited for premium residential, commercial, and industrial installations, as well as PV farms, where every percentage point of energy yield and predictability is crucial. ## Notable figures - Efficiency of 15.3% is 4.1pp below the \*\*PERC 0-400W\*\* median (19.4%) - At 152.7 W/m², this panel generates 41.7 W/m² less per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - Temperature coefficient of -0.37%/°C matches the \*\*PERC 0-400W\*\* median - 15.1 kg weight - 5.4 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg), reducing installation effort - Ranked #13753 out of 14005 panels for efficiency in the database ## Questions ### Is the JA Solar 5M series still available for purchase? The JA Solar 5M series has been discontinued and is no longer available as a new product through standard distribution channels. Limited quantities may occasionally appear at distributors as existing stock. If you are planning a new installation, it is worth checking stock availability or considering a current JA Solar series based on newer cell technologies with higher wattage output. ### What cell technology does the JA Solar 5M series use, and what does it mean in practice? The JA Solar 5M series uses monocrystalline PERC (Passivated Emitter and Rear Cell) technology. The passivation layer on the rear side of the cell reduces electron recombination losses and improves light absorption, resulting in higher efficiency compared to older Al-BSF cells. In practice, this means better energy yield from the same roof area, especially noticeable under diffuse light conditions. Maximum module power for this series is 215 Wp. ### What warranty does the JA Solar 5M series come with? JA Solar provides a 12-year product warranty covering material and workmanship defects, and a 25-year linear power output warranty. The linear power warranty guarantees a gradual, predefined degradation curve rather than a stepwise drop. JA Solar holds Tier 1 status per Bloomberg NEF rankings, which reinforces the credibility of its warranty commitments even for older, discontinued product lines. ### Are JA Solar 5M panels suitable for installation on a sloped residential roof? Yes, the 5M series modules in the 60-cell format (up to 215 Wp) have compact dimensions and moderate weight, making them easier to transport across roof surfaces and mount on standard racking systems. The monofacial design — with no light harvesting from the rear — is the standard for rooftop installations where the back of the panel faces the mounting structure. The series is well-suited for residential prosumer systems and small commercial projects. ### How does the JA Solar 5M series perform under overcast skies and variable weather? The PERC technology in the 5M series delivers better performance under diffuse light compared to older Al-BSF cells, which is particularly relevant in climates with a high share of overcast days. The low power degradation guaranteed by the 25-year linear power warranty ensures that energy yields remain predictable throughout the full operational lifetime of the installation. ### How does the JA Solar 5M series differ from the manufacturer's newer modules? The 5M series is an older product based on PERC technology with a maximum output of 215 Wp, intended primarily for smaller installations. Newer JA Solar product lines — such as Deep Blue 4.0 or the n-type TOPCon series — offer significantly higher per-module wattages (400–600+ Wp), improved module efficiencies, and better temperature coefficients. Since the 5M series is discontinued, it is relevant only for expanding or replacing panels in an existing installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Product-specification-MY5M72-195-215-ENG20200101-5316ed4aa8e0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | Lighter, +7.7 pp, +5 yr warranty | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | Lighter, +7.7 pp, +5 yr warranty | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | Lighter, +7.7 pp, +5 yr warranty | | [Gamko New Energy GKA182M200W](https://comparepv.com/panel/gamko-new-energy-gka182m200w) | 200 W | Lighter, +7.7 pp, +5 yr warranty | | [Gamko New Energy GKA182M240W](https://comparepv.com/panel/gamko-new-energy-gka182m240w) | 240 W | +45 W, +7.7 pp, +5 yr warranty | | [JA Solar NS-220MH-80](https://comparepv.com/panel/ja-solar-ns-220mh-80) | 220 W | Cooler, lighter, +6.8 pp | | [PolyCrown Solar Tech NS-220MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-220mh-80) | 220 W | Cooler, lighter, +6.8 pp | | [JA Solar NS-210MH-80](https://comparepv.com/panel/ja-solar-ns-210mh-80) | 210 W | Cooler, lighter, +5.8 pp | | [PolyCrown Solar Tech NS-210MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-210mh-80) | 210 W | Cooler, lighter, +5.8 pp | | [IBC Solar YH215W-21M](https://comparepv.com/panel/ibc-solar-yh215w-21m) | 215 W | Lighter, +5.5 pp, +5 yr warranty | | [JA Solar MY5M72-200](https://comparepv.com/panel/ja-solar-my5m72-200) | 200 W | +0.4 pp | | [JA Solar MY5M72-205](https://comparepv.com/panel/ja-solar-my5m72-205) | 205 W | +10 W, +0.8 pp | | [JA Solar MY5M72-210](https://comparepv.com/panel/ja-solar-my5m72-210) | 210 W | +15 W, +1.1 pp | | [JA Solar MY5M72-215](https://comparepv.com/panel/ja-solar-my5m72-215) | 215 W | +20 W, +1.5 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | +85 W, cooler, +8.0 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | +90 W, +7.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/ja-solar-my5m72-195 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
