Light for its output, weak in heat
Easun Power YH Mono Portable is a series of panels designed for maximum mobility without compromising on light conversion efficiency. The use of high-efficiency monocrystalline cells allows for effective energy harvesting even with limited surface area, which is crucial in field conditions and during stops. This series stands out with its lightweight foldable design, which effectively eliminates the problem of transporting heavy equipment during camping trips, yachting, or field work. Thanks to the use of an advanced ETFE coating, the panels exhibit exceptional resistance to scratches and negative weather conditions, which significantly extends their lifespan compared to standard tourist solutions. Integrated adjustable-angle kickstands allow for precise positioning of the modules relative to the sun in just a few seconds, resulting in tangibly higher energy yields throughout the day. This is a professional solution dedicated to camper van users, boat owners, and individuals using portable power stations who require reliability in all circumstances. Unlike rigid modules, the YH Mono Portable series focuses on full plug-and-play readiness, offering energy freedom without the need for permanent installation. This combination of industrial durability and functionality makes Easun Power redefine the concept of mobile photovoltaics.

HJT cells deliver a temperature coefficient of approximately -0.24%/°C, compared to -0.35%/°C for mainstream PERC and ~-0.30%/°C for TOPCon. 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 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.
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.
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.
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.
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.
- At 20.5% efficiency, this panel is on par with typical HJT 0-400W modules
- Power density of 205.0 W/m² matches the HJT 0-400W median
- At -0.40%/°C, loses 0.14pp more power per degree than HJT 0-400W median (-0.26%/°C)
- Weight of 3.6 kg (17.9 kg below HJT 0-400W median of 21.5 kg) allows easier transport and roof mounting
- Ranked #11308 out of 14005 panels for efficiency in the database
