290W Thin Frame Junction Box UNDERNEATH 5.5kg, 1662 x 1019 x 5.6mm

This 5.6mm thin solar panel weighs only 5.5 kg. These lightweight yet robust solar panels are perfect for caravans, motorhomes, yachts, trains, buses and other applications. 

Made with a Patent Pending composite material similar to those used in airplane windows.  These panels are tough enough to be approved by the Clean Energy Council for residential use yet they don't have a heavy, rigid frame or glass.

Mounting Options:

  • The vented gap (height increase of ~15mm) improves panel efficiency and reduces heating of the mounting surface. This method also allows the junction box to sit underneath the panel. This includes:
    • Two rolls of very high bond double sided adhesive tape
    • Polycarbonate strips
  • Installation via very high bond double sided adhesive tape provides a low profile secure bond. This includes:
  • A structural silicone (Fix8) can be used to adhere the panel to a surface.
  • The panel can be secured using bolts or screws through the frame 
  • NOTE: Although the panel has a thin frame around the edge, the panel is flexible and requires supports at least every 156mm (every cell gap)
