Description

Monocrystalline 20 watt solar assist panel with built-in charge regulator and mounting stake. Solar assist panels connect directly to your 12v battery extending the period between battery charges or cutting out the need for charges altogether. Fitted with built-in charge controller to charge against over-charging and discharge of the battery.

Our panels also come with a sturdy mounting stand.

Other information: The level at which the panel will extend the life of your battery is dependent on the power of your energiser and the duration and strength of available sunlight. The stronger the energiser, the more quickly it will draw power from the battery and the less time the panel has to replace the charge. The ability of the panel to produce and replace the energy used by your energiser is indicated by the watt capacity of the panel, so a 20 watt panel will replace the charger quicker than a 10 watt panel.
