The SR Series utilise Merlin solar cells

The monocrystalline high efficiency SR cells are sandwiched by two patented metallic grids that serve as intracell and inter-cell interconnects. The same copper and solder as any other bus bar cell are used, but 20 redundant lines and 180+ interconnects, not only enable to extract more power but also dramatically improve the reliability, performance and ruggedness of the solar panels.  The grid on the front is carefully tailored to optimize the current harvesting, while the one behind the cell provides strong mechanical support. The grids essentially form a double shield that acts as a conducting reinforcement to the solar cell. Extreme crack and bend tolerance are built in, enabling novel crystalline silicon architectures. A guarantee of high efficiency and unmatched durability in flexible solar panels.

Installation Manual:


As with all Solbianflex panels, only whole cells are used.  This means that the voltage increases with the panel wattage, whereas the current is the same for all panels.  For example the SR62 has 14 cells in series giving just over 7V, whereas the SR160 has 36 cells in series giving just over 18V.  The amps for both panels is 8.6Amp.


  • High tolerance to cracks and bending thanks to the double shield protecting the cell
  • Flexible and lightweight (2.2 kg/m2)
  • Completely waterproof and resistant to salt water
  • Thin (less than 2 mm)
  • 5 year warranty against manufacturing defects
  • Integrated bypass diodes to minimise output losses associated with partial shading
  • Available with different front sheets, many fixing and electrical wiring options (special order)
  • White, black or transparent back sheet (special order)
  • Junction box on top or underneath (special order)
  • 316 stainless steel eyelets (fitted by Solar 4 RVs)
  • Bi-adhesive backing covering the entire back surface of the panel (special order)
  • Charge 12V, 24V, 36V or 48V batteries, lead-acid or lithium, using a Genasun boost charge controller - refer
  • Designed and manufactured in Italy

Safety class A

* Values at STC = Standard Test Conditions: (a) light Spectrum for an Air Mass of 1.5; (b) irradiance of 1000 W/m2 with perpendicular incidence and (c) cell temperature of 25 °C. Measurements carried out according to the Standard IEC 61215 requirements.

* This NOCT is based on the STC and assume an air gap behind with 1m/s air flow.  In practice a panel directly bonded to an insulated substrate will be much hotter
** For best case safety,  only wire in series to raise the string voltage high enough for the charge controller, e.g 18V for a 12V battery, 36V for a 24V battery
