eArche is the next generation thin solar panel with 10 year manufacturer's warranty

eArche (pronounced e-Arc) is a robust, lightweight, flexible solar panel that is perfect for caravans, motorhomes, boats, golf carts, trains, buses and other applications.

What makes them different?eArche thin lightweight solar panels have a tough top layer

  • The manufacturers warranty is 10 years and the output warranty is the same as high grade rigid solar panels used on buildings: above 80% of the original power by the 25th year. 
  • Edging that protects the layers of the panels.  The 2mm thin panels have either a 5.6mm thin frame, 20mm standard frme or 6.0mm EPDM rubber edging.
  • Made with a Patent Pending composite material similar to those used in airplane windows.  These panels are approved by the Clean Energy Council for grid connection in residential and commercial applications yet they don't have a heavy, rigid frame or glass.
  • eArche has obtained a series of certifications for reliability, including: 

eArche accreditation and standards

                             ​The strict Japan Electrical Safety & Environment Technology Laboratories (JET);

                                       The International Electrotechnical Commission (IEC) which is widely recognised quality standard certifications throughout the solar industry;

                                       CE mark indicatings the panel meets the minimum European Union requirements for Electro Magnetic Compatibility (EMC) compliance;

                                       CSA International certification for Canada and U.S.

                                       Approval by Australia's Clean Energy Council;

The Clean Energy Council (CEC) maintains the database and website listing of AS/NZS 5033-compliant photovoltaic (PV) modules for grid-connected commercial and residential applications. (Note: CEC approval is not required for solar panels on RVs and boats and other mobile applications as they are not connected to the grid.)

eArche was created by Dr Zhengrong Shi, known as the ‘Sun King’ and his Australian/Chinese team.  Dr Shi was born in Jiangsu province, China and obtained his PhD at the School of Photovoltaic and Renewable Energy Engineering at the University of New South Wales (UNSW).  He acquired Australian citizenship and now straddles Australia and China.


Three edging options:  

1)   8mm thickness EPDM rubber edging

This option provides a lightweight bendable edge protection for the panel.  The flexibility of this panel enables installation on curved surfaces.  Installation via high bond double sided adhesive tape or adhesive sealant provides a low profile secure bond.

2)   6mm thin lightweight black anodized aluminium alloy frame 

This option provides support without thickness.  These panels have some flex but are not bendable.  This allows installation on thin, lightweight aluminium channels for an air gap.  High bond double sided tape or adhesive sealant can also be used for a low profile installation.

3)   20mm thickness standard lightweight black anodized aluminium alloy frame 

This option provides additional strength and rigidity without weight.  They have no flexibility thereby providing excellent support for such a lightweight thin panel.  Installation with brackets can provides an air gap.  These are not kept in stock but can be ordered in.
