Light for its output, weak in heat
The Easun Power FLEXIBLE SOLAR PANEL series is designed for situations where a traditional framed module simply doesn't work - on camper roofs, boats, van bodies, trailers, as well as on lightweight structures and surfaces with a gentle curve. The key advantage is the flexible, ultra-light construction, which allows you to mount the panel without affecting the roof's load-bearing capacity and without heavy frames.
In practice, you get faster installation - the panel can be attached with adhesive or through mounting holes, which reduces the time required and minimizes the risk of leaks. The ETFE protective layer provides high resistance to UV and marine conditions, while also making it easy to keep the surface clean. Monocrystalline cells in a modern design support more stable operation in partially shaded conditions, typical for areas under railings, luggage compartments, or roof accessories.
This is the choice for those who want energy independence on the move and real energy production from a limited space, without compromising on durability.

HJT cells deliver a temperature coefficient of approximately -0.26%/°C, which is more favorable than standard PERC cells at -0.35%/°C. They also minimize both Light-Induced Degradation (LID) and Potential-Induced Degradation (PID) — a critical advantage for flexible panels exposed to intense irradiance on the metal roofs of RVs and boats.
Compared to direct competitors in the same 100 Wp power class, this panel achieves significantly higher efficiency than the Wanze Energy DLXN-M10 (17.0%) and the TPL Solar TPL S-36 (15.67%) — by +2.63 and +3.96 percentage points, respectively. On the constrained roof area of an RV or boat, that translates into meaningfully more energy output from the same footprint.
The ETFE (ethylene tetrafluoroethylene) top layer offers exceptionally high resistance to UV radiation and saltwater exposure, surpassing the cheaper PET alternative used in budget flexible panels. The hydrophobic ETFE surface reduces dirt accumulation and promotes self-cleaning during rainfall.
The flexible, frameless construction allows attachment via contact adhesive or grommets, eliminating the need for drilling or heavy racking hardware. A 100 Wp flexible panel typically weighs 1.5–2.5 kg versus 5–7 kg for a rigid framed equivalent — a meaningful difference when working within the payload limits of a boat or a lightweight van build.
The JA Solar Monocrystalline36 100 Wp achieves 21.29% efficiency — 1.66 percentage points higher than the Easun at 19.63%. On an identical mounting surface, that gap amounts to roughly 8% less energy output. For space-constrained installations such as an RV rooftop, the difference is noticeable in annual energy yield.
Easun Power has a well-established track record as an inverter and charge controller manufacturer (operating since 2006), but the brand does not appear in the BNEF Tier-1 PV module rankings or the PVEL PV Module Reliability Scorecard. Flexible panels represent a niche side product for this brand, which raises the risk of limited warranty support and service availability over a 10+ year horizon.
ETFE flexible panels typically deliver 10–20 years of service life with an annual degradation rate of 0.5–0.7%, while rigid glass-faced counterparts maintain performance for 25–30 years at 0.3–0.5%/year. In stationary applications — such as a carport or terrace installation — the Easun FLEXIBLE series cannot match the long-term durability of Tier-1 framed modules.
