The Solarex SX-LITE panels weigh about 2 pounds and put out 18 watts, at a retail cost of $175 or so. Admittedly this is not cheap, but that's 1.2 amps per panel of charge current (they're scaled for direct connection to 12V batteries, and can be series-connected for 24). Application is trivial... sunlight in, two wires out. Add a schottky to prevent dark discharge and you're done, unless the panels are substantially more robust than the batteries, in which case a controller is required. Solarex is at 800-521-SOLA and a Bay Area distributor is Energy Depot at 415-499-1333 in San Rafael. Cheers... Steven K. Roberts Nomadic Research Labs
