This waterproof high efficiency 5W solar panel is perfect for permanent outdoor use to provide free power either directly, such as powering a light or small fan, or for trickle charging 12V battery / battery bank in a motorhome, caravan, car, boat, shed or garden.

The long-lasting, high-efficiency, monocrystalline solar cells and the tough, sealed, aluminium frame will give you years and years of consistent, free power. Waterproof design ensures the panel can be used in all weather conditions.

Solar panel comes with 2m cable attached to the waterproof connection box at the back and is fitted with a blocking diode to prevent reverse current from the battery to the solar panel at night (no need to disconnect the panel every night).

This solar panel can be used for trickle charging 12V lead acid batteries with capacity 50Ah and higher directly. For smaller batteries a solar charge controller is recommended to prevent overcharging (not included with the solar panel). Without a solar charge controller the state of charge of smaller batteries should be monitored constantly.



Solar panel specifications:

  • Peak power: 5W
  • Maximum power voltage: 17.5V
  • Maximum power current: 0.28A
  • Open circuit voltage: 21.6V
  • Short circuit current: 0.30A
  • Power allowance range: +/- 3%
  • Dimensions: 25 x 19 x 2 cm
  • Weight: 0.8 kg
  • 4 mounting holes
  • 2m of 1.5mm cable


The product is covered by 1 year workmanship warranty provided by Photonic Universe. We will repair or replace defective items at our discretion. For more information please refer to our Terms and Conditions.



Please note: like all standalone solar panels, this solar panel does not include installation instructions as it assumes prior knowledge.
