eArc – Ultra-light, Glass-free Technology

eArc is the world’s first glassless solar module. An innovation combining proven crystalline silicon solar cells with Sunman’s patented composite material (ZL201610927464.6，ZL201610927383.6，EP3534410), eArc has the same durability and robustness of conventional glass modules. However, unlike glass: eArc is akin to a flexible”solar skin”, 70% lighter and up to 95% thinner. eArc requires 0 penetration or mounting equipment during installation, cutting time-on-site by 40%. eArc is easier to transport in bulk – up to 60% more kW per pallet. eArc targets a variety of applications glass modules cannot service.

Do More with Less – eArc Applications

Sunman sees eArc as a core-enabling technology that will expand the market and deployment of solar. Currently, eArc addresses several markets that glass modules underserve, including lightweight C&I roofs, waterproof membrane roofs, vehicle integrated photovoltaics and off-grid energy. Moreover, eArc is paving the way for new innovations, gaining momentum in cross-market applications such as building materials and robotics.

Same Durability as Glass

eArc is the first module of its kind to pass the same durability and safety tests as glass modules, including IEC 61215:2016, IEC61730:2016 and UL1703 (USA). The IEC61215 confirms eArc’s ability to withstand prolonged exposure to open air climates. eArc has also passed additional module quality assessments, including 3000 hours of damp heat, UV exposure (25 years equivalent), PID, salt mist and ammonia corrosion tests.
