The extended warranty improves long-term financial predictability for the installation. - **Up to 17.4% Efficiency — Top of the Poly Segment** - A peak module efficiency of 17.4% places the series well above the Solitek SOLID Solrif (14.45%) and only 0.12 percentage points below leading contemporaries — the Yingli LF285P6-60 and Lina Energy LPEPV 60 SUPERIOR (both at 17.52%). For a 60-cell multicrystalline module, this is a highly competitive result. - **PID Resistance** - The integrated potential-induced degradation (PID) prevention technology is particularly relevant in systems operating at high DC voltages, typical of Polish three-phase arrays exceeding 600 V DC. It mitigates premature power loss — a critical factor over a 30-year operational horizon. - **Enhanced Mechanical Frame Strength** - The frame is engineered to withstand elevated snow and wind loads, making it a key advantage for rooftop installations in Poland where snow loads can exceed 1.5 kN/m² in mountainous and sub-alpine regions. - **High-Transmittance Tempered Glass** - The use of tempered glass with an anti-reflective coating and enhanced transmittance improves energy yield at low solar incidence angles — particularly relevant in the Polish climate from October through March, when the solar elevation angle falls below 25°. ## Cons - **Series Discontinued (since 2021)** - The EX270-285P(B)-60 modules have not been in production since approximately 2021. Availability of identical replacement modules is limited to distributor warehouse stock. In the event of a single panel failure within an existing array, electrical matching to a module from a different series may be impractical or cost-prohibitive. - **No Tier-1 Bankable Status During Production Period** - Per the available data (tier\_1\_bankable: false), the series was manufactured before Exiom Solution achieved bankable manufacturer status. This complicated project financing via bank loans or leasing arrangements that require warranties from a BNEF Tier-1 recognized manufacturer. - **P-Type Multicrystalline Technology — Outdated** - Multicrystalline cells exhibit higher annual degradation rates (typically 0.7–0.8%/year versus 0.45–0.55%/year for mono PERC/TOPCon). Over a 30-year warranty period, the elevated degradation rate results in proportionally lower actual energy yield at end-of-warranty compared to modern technologies available from approximately 2018 onward. - **No Bifacial Capability** - The series is monofacial (is\_bifacial: false). Competing modules released concurrently or after 2018 began offering bifacial technology in this power class, generating an additional 5–15% yield gain from albedo reflection. For installations on high-reflectance surfaces — gravel, concrete, or snow — this represents a tangible production loss. ## About this series The Exiom EX270-285P(B)-60 solar panel series is an advanced solution based on **high-efficiency polycrystalline cells**, which have been designed to maximize energy yields while maintaining optimal investment costs. These modules stand out for their exceptional stability of electrical parameters, which directly translates into long-term energy security for users. Thanks to the use of technology preventing potential-induced degradation, these panels solve the problem of premature power loss, which is crucial in the variable weather conditions typical of the Polish climate. The frame construction provides **increased resistance to mechanical loads**, such as accumulated snow or strong wind gusts, making them an ideal choice for rooftop installations in regions with harsher atmospheric conditions.

The Exiom EX270-285P(B)-60 series has been discontinued and is no longer offered as a new product. If you are specifically interested in modules from this manufacturer, it is worth checking Exiom Solution's current lineup, which includes newer monocrystalline modules with higher efficiency ratings. Used units from this series may still appear sporadically on the secondary market; however, prior to any purchase we strongly recommend verifying the technical condition of the modules and reviewing the associated warranty documentation. ### What is the linear power output warranty for the Exiom EX270-285P(B)-60 panels? The manufacturer offers a 30-year linear power output warranty for the EX270-285P(B)-60 series, which exceeds the typical industry standard of 25 years. This means that throughout the entire warranty period, each module is guaranteed to retain a specified minimum percentage of its nominal power output (285 Wp). Such an extended warranty term underscores the predictability of energy generation and significantly reduces the financial risk of the investment over a multi-decade horizon. ### How do the polycrystalline cells used in the Exiom EX270-285P(B)-60 differ from monocrystalline cells, and is this a disadvantage? The polycrystalline cells used in this series are slightly less efficient than monocrystalline cells, meaning that a marginally larger roof area is required to achieve the same power output. In return, they offer a lower unit cost and good long-term parameter stability. For a typical residential installation or small commercial application where roof space is not critically limited, this represents a reasonable trade-off between technology performance and the economics of the investment. ### Can the Exiom EX270-285P(B)-60 panels handle the Polish climate, including snow loads and strong winds? Yes, the EX270-285P(B)-60 series was designed with a reinforced aluminum frame that provides enhanced resistance to mechanical loads. The modules are rated to withstand accumulated snow loads and strong wind gusts typical of Polish weather conditions. High-transmittance tempered glass further protects the cells and enables efficient operation even at the low solar irradiance angles characteristic of winter months. ### What is Anti-PID technology, and does the Exiom EX270-285P(B)-60 series incorporate it? PID, or Potential-Induced Degradation, is a phenomenon that causes premature power loss in PV modules and is particularly problematic in high-voltage systems and high-humidity environments. The EX270-285P(B)-60 series is equipped with Anti-PID technology, meaning that the cells and encapsulant materials have been specifically selected to minimize charge carrier leakage. This results in more stable energy yields throughout the entire operational lifetime of the installation. ### Are the 285 Wp Exiom EX270-285P(B)-60 modules sufficient for a typical single-family home? A single 285 Wp panel is only one component of a complete PV system. For an average single-family home consuming approximately 3,500–5,000 kWh per year, a system typically requires 10 to 16 such modules (a 3–5 kWp installation). The EX270-285P(B)-60 series is well suited for such applications; however, given that the product has been discontinued, assembling a complete new system from this series is no longer straightforward. It is worth considering newer, higher-wattage modules, which will deliver the required output while occupying less roof area. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EX270-285PB-60-0a2cbcac62fa.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Canadian Solar CS3K-320P](https://comparepv.com/panel/canadian-solar-cs3k-320p) | 320 W | +50 W, +2.8 pp, -5 yr warranty | | [Canadian Solar CS3K-315P](https://comparepv.com/panel/canadian-solar-cs3k-315p) | 315 W | Cooler, +2.5 pp, -5 yr warranty | | [SunLink LNSK-320M](https://comparepv.com/panel/sunlink-lnsk-320m) | 320 W | +50 W, +2.4 pp, -5 yr warranty | | [Canadian Solar CS3K-310P-AG](https://comparepv.com/panel/canadian-solar-cs3k-310p-ag) | 310 W | +40 W, cooler, +2.2 pp | | [Rarlon PV Tech RL310HP-120](https://comparepv.com/panel/rarlon-pv-tech-rl310hp-120) | 310 W | +40 W, cooler, +2.1 pp | | [SunLink LNSK-315P](https://comparepv.com/panel/sunlink-lnsk-315p) | 315 W | Cooler, +2.1 pp, -5 yr warranty | | [Canadian Solar CS3K-310PB-AG](https://comparepv.com/panel/canadian-solar-cs3k-310pb-ag) | 310 W | +40 W, cooler, +1.9 pp | | [Exiom EX275P-60](https://comparepv.com/panel/exiom-ex275p-60) | 275 W | +0.3 pp | | [Exiom EX280P-60](https://comparepv.com/panel/exiom-ex280p-60) | 280 W | +10 W, +0.6 pp | | [Exiom EX285P-60](https://comparepv.com/panel/exiom-ex285p-60) | 285 W | +15 W, +0.9 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | +130 W, cooler, +6.1 pp | | [Lina Energy LEPV 400](https://comparepv.com/panel/lina-energy-lepv-400) | 400 W | +130 W, cooler, +5.8 pp | | [Phono Solar NS-360MH-60](https://comparepv.com/panel/phono-solar-ns-360mh-60) | 360 W | +90 W, cooler, +5.6 pp | | [PolyCrown Solar Tech NS-360MH-60](https://comparepv.com/panel/polycrown-solar-tech-ns-360mh-60) | 360 W | +90 W, cooler, +5.6 pp | | [Maxeon SPR-MAX3-390-COM](https://comparepv.com/panel/maxeon-spr-max3-390-com) | 390 W | +120 W, cooler, +5.6 pp | | [Meyer Burger MB\_TG120ByB\_390](https://comparepv.com/panel/meyer-burger-mb-tg120byb-390) | 390 W | +120 W, cooler, +5.3 pp | --- Source: https://comparepv.com/panel/exiom-ex270p-60 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
