The solar panel (Solarex MSX20L) is connected to a 12VDC motorcycle battery. A controller (Bolier Elec. Sun Solector M08012V-T) is set up between the solar panel and the battery. The controller serves two purposes. It prevents a reversal of the current when it becomes dark and prevents an overcharge of the battery by periodically testing the battery. Both the controller and the battery can be placed in a dry box or ammo can to allow charging to occur when proceeding down the river.

While charging, the battery should be placed in an area that is between 70-90 degrees F. Batteries will not charge in cool temperatures (for example, near the bottom of a rafts storage area, close to the cool river).

When required the 12 VDC motorcycle battery can be used to run appliances or to charge another battery. In this case the 12 VDC battery is connected to an inverter to produce 120 VAC. A normal AC camcorder battery charger is connected to the inverter for quick and efficient charging.

Other appliances like 12VDC lights can run directly off the battery.

Advantages	Disadvantages
The solar panel continues to charge the battery even when there is not direct sunlight.	More expensive
The 12 VDC battery can be used for multiple purposes. One rafter connected a 12 VDC battery to a water pump. It would empty his water filled raft in 20-30 seconds.	More equipment to lug around.
Some controllers indicate when there is a current detected. This is useful for determining when the 12 VDC battery is no longer accepting current.
Uses normal AC battery charger that comes with most camcorders and other devices.
