About this product

Convenient, portable solar cell for recharging AA batteries. Five hours of sunlight completely recharges the batteries. Perfect for longer trips where the GPS, radio or headlamps need more power. Use two batteries in the equipment you're using and let the other two recharge during the day. Includes suction cups for attachment to windows.

The ideal battery type to be recharged in the Solar I is Nickel Metal Hydride (Ni-MH) Batteries. Nickel Cadmium (NiCd) batteries can also be used. Typically, when used in ideal conditions, the Solar I will recharge (from flat) 2 x AA 1,600mAh NiMH batteries in around 5 Hours, or 4 x AA 1,600mAh NiMH batteries in 10 Hours. Recharge times will vary with both battery capacity and available light level.



Power output in different conditions:

The Solar I charger operates best in clear skies and in direct sunlight. To optimise the power output of both units, position the solar charger in direct sunlight, with no shadows being cast on the front surface of the panel. As a general rule, Solar I will produce the power rates, specified below, when faced directly at the sun:

* Direct Sun with panel faced directly at the sun - 100%

* Direct Sun with reflections from water surface, snow etc - up to 125%

* Partly cloudy (enough to cast a shadow) - approx. 50%

* Cloudy - approx. 10%


Performance in different temperatures:

The performance of the Solar I is affected by temperature. Best performance will be obtained on a clear sunny day in low temperatures. This is due to the fact that the output of solar panels drops with an increase in the surface temperature of the solar cells.


Solar I Mounting:

The Solar I has been designed to mount in a number of different ways to a variety of different products:

Rucksacks, bags etc: Use nylon strapping (not supplied) up to 25mm wide. Pass the webbing through the slots provided along the top and bottom edges of the charger casing, and secure using the buckles provided with your webbing.

Windows, glass etc: Use suction cup mounts provided.

Please note that the performance of the Solar I will be diminished by 10 to 25% when operating through glass. Do not use the Solar I where the glass has been treated with an anti-reflective coating as the output of the charger may drop to as low as 10%, even in ideal conditions.
