SolbianFlex SP series panels are made in Italy and uses SunPower patented back-contact monocrystalline silicon cells which eliminates conductors on the top surface which reduces the efficiency of other cells in comparison. The cell efficiency of 24% enable the SP range to provide the highest output power from the smallest surface area of any panel available today and hence are recommended for installations on yachts where maximum power is required from limited surface area.  The SunPower cells also achieve the lowest loss in partial shading and high temperature situations compared with other cells.

  • 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 https://www.solar4rvs.com.au/solar-charge-controllers/mppt-voltage-boost-solar-charge-controllers/
  • Designed and manufactured in Italy

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 SP52 has 16 cells in series giving just over 9V, whereas the SP104 has 36 cells in series giving just over 18V.  The amps for both panels is 5.7Amp.  You will need a Genasun MPPT voltage boosting charge controller if you need to charge a battery that has a higher voltage than the panel, otherwise a Victron MPPT charge controller is recommended for boats where the panel Voltage (Vmp) is at least 50% above the battery nominal voltage*, ie, Vmp = 18V for a nominal 12V battery;   Vmp = 36V for a nominal 24V battery,  72V for a 48V battery (irrespective of the battery being lead-acid or lithium.   Otherwise a PWM charge controller is recommended where the Vmp is above the battery voltage but doesn't meet the required voltage for the MPPT to work.

*applies to most batteries but there are exceptions and we are happy to advise if unsure.

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
