Under real-world summer conditions (cell temperature 55°C), HJT loses roughly 3.4% of rated power versus ~5% for PERC — a tangible energy yield gain on high-irradiance camping days. - **ETFE Encapsulant Instead of Tempered Glass** - ETFE reduces the weight of a portable panel by approximately 40–50% compared to standard glass while maintaining high light transmittance (~95%) and strong UV and scratch resistance. For a mobility-focused series this is a critical design parameter that heavier glass-fronted competitors — such as the ZOUPW 200W Tempered Glass — cannot match. - **Plug-and-Play Without Permanent Installation** - The foldable housing with adjustable kickstands allows the user to set the optimal tilt angle in seconds and without tools. Native compatibility with portable power stations via MC4, USB, and DC connectors makes the YH Mono Portable series a ready-to-use solution for RV owners and sailors, with no electrician required. - **Manufacturer With Nearly 20 Years of Industry Experience** - Easun Power has been operating since 2006 and holds an established position in the off-grid segment — covering hybrid inverters and MPPT charge controllers. A complementary ecosystem of single-brand devices minimizes compatibility risks when building a complete mobile power system. ## Cons - **Module Efficiency of 20.5% — Below Segment Median** - The peer-comparable Gamko New Energy GKA182M (200 Wp) achieves 23% efficiency — 2.5 percentage points higher — which, at the same rated power output, translates to roughly 12% less active area required. Premium-class 200 W portable panels with HJT cells currently available on the market (e.g., LETSFAB 220W HJT at 25%; ZOUPW 200W at 23.5%) reach significantly higher values; 20.5% for an HJT module falls below the typical 22–25% range expected of this cell technology. - **No Independent Laboratory Test Results for the YH Series** - Easun Power is not listed in the ENF Solar database as a certified PV module manufacturer (as distinct from its inverter credentials), and the YH Mono Portable series has no publicly available IEC 61215/IEC 61730 test results or reports from independent laboratories such as PVEL or TÜV. This makes it difficult for installers and distributors to independently verify the declared power output and long-term durability. ## About this series Easun Power YH Mono Portable is a series of panels designed for maximum mobility without compromising on light conversion efficiency.

HJT (Heterojunction Technology) combines monocrystalline silicon cells with a thin amorphous silicon layer, achieving efficiencies of 22–26% — higher than conventional PERC cells. In portable panels, this is particularly significant: a smaller surface area is sufficient to deliver 200 W of output power. An additional advantage is the low temperature coefficient (approx. -0.26%/°C), which means the panel loses less power on hot days at a campsite or during stops on a road trip with an RV. ### Is the Easun Power YH Mono Portable 200 W sufficient to power a portable refrigerator and charge a power bank simultaneously? Under good irradiance conditions, a 200 W panel generates approximately 800–1,000 Wh per day, which is generally sufficient to run a compact 12 V refrigerator for several hours while simultaneously charging a portable power station. Actual energy yields depend on the tilt angle — adjustable via the integrated kickstands of the YH Mono Portable series — as well as the number of peak sun hours available at the given location. ### How does the Easun Power YH Mono Portable perform in low temperatures, such as during autumn RV trips? The HJT cells used in the YH Mono Portable series feature one of the lowest temperature coefficients available in the portable panel market (approx. -0.26%/°C). This means that at 10°C instead of the standard test condition of 25°C, the panel loses only about 4% of its rated output power. This is a significant advantage during cooler trips — the panel operates efficiently year-round, not just in summer. ### Which portable power stations are compatible with the Easun Power YH Mono Portable panel? The YH Mono Portable series features an MC4 connector and operates in plug-and-play mode, ensuring compatibility with the majority of popular portable power stations — including Jackery, Bluetti, EcoFlow, Anker, and others — equipped with a DC or MC4 input port. Before purchasing, it is advisable to verify the maximum input voltage accepted by your power station and compare it against the panel's specifications. The open-circuit voltage (Voc) of the YH Mono Portable series is listed in the product datasheet. ### How durable is the ETFE coating on the Easun Power YH Mono Portable panels, and how does it differ from standard PET film? The ETFE (ethylene tetrafluoroethylene, a fluoropolymer) coating offers significantly greater resistance to scratching, UV radiation, and moisture than the lower-cost PET film used on entry-level portable panels. Unlike PET, ETFE does not yellow over time, maintaining high light transmittance throughout the panel's service life. In practice, this translates to a longer operational lifespan and reduced power degradation of the monocrystalline cells in the YH Mono Portable series during extended field use over many years. ### How much does the Easun Power YH Mono Portable weigh when folded, and will it fit in an RV trunk or a yacht storage compartment? The YH Mono Portable series was designed as a lightweight and compact solution — its foldable construction significantly reduces the footprint compared to rigid 200 W modules. When folded, the panel occupies a fraction of its deployed surface area and fits easily in an RV trunk, a yacht storage locker, or a car's cargo area. The exact folded weight and dimensions for each specific model in the YH Mono Portable series are provided in the corresponding product datasheet. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/200w-12m-1235x790x2-5-7649b5fd2734.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | -50 W, heavier, +2.5 pp | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | -40 W, heavier, +2.5 pp | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | -20 W, heavier, +2.5 pp | | [Gamko New Energy GKA182M200W](https://comparepv.com/panel/gamko-new-energy-gka182m200w) | 200 W | Heavier, +2.5 pp | | [Gamko New Energy GKA182M240W](https://comparepv.com/panel/gamko-new-energy-gka182m240w) | 240 W | +40 W, heavier, +2.5 pp | | [JA Solar NS-220MH-80](https://comparepv.com/panel/ja-solar-ns-220mh-80) | 220 W | Cooler, heavier, +1.6 pp | | [PolyCrown Solar Tech NS-220MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-220mh-80) | 220 W | Cooler, heavier, +1.6 pp | | [Isola New Energy YH250W-16M](https://comparepv.com/panel/isola-new-energy-yh250w-16m) | 250 W | +50 W, cooler, heavier | | [JA Solar NS-210MH-80](https://comparepv.com/panel/ja-solar-ns-210mh-80) | 210 W | Cooler, heavier, +0.6 pp | | [PolyCrown Solar Tech NS-210MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-210mh-80) | 210 W | Cooler, heavier, +0.6 pp | | [Centro Energy CE-180M60](https://comparepv.com/panel/centro-energy-ce-180m60) | 180 W | -20 W, hotter, heavier | | [Isola New Energy YH200W-12M](https://comparepv.com/panel/isola-new-energy-yh200w-12m) | 200 W | Very close match | | [JA Solar NS-200MH-80](https://comparepv.com/panel/ja-solar-ns-200mh-80) | 200 W | Cooler, heavier, -0.4 pp | --- Source: https://comparepv.com/panel/easun-power-yh200w-12m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
