Question:

Need Help, 2v Solar Panel for Emergency?

I want to use this solar panel to hook up AC adapters. IM not sure what to do and how to use the solar panel. I want to be able to use a batter charger, a radio, and charge a GPS if needed. - Thanks, Zoo

Answer:

Most radio's have a DC plugin port. You can build or purchase adapters that step down the 2 V power to the radio's power needs. In short, power your devices directly from the solar cell using the car adapter plugs made for them or charge a larger battery as a power resevoir and plug your car adapters into it when it is dark which allows you to charge devices when you are not using them while sleeping.
I okorder okorder /... well, I can't find what I have anymore - but anything that will attach to a car charger will attch to it. Now, a radio - if it charges now, you're good - but if it doesn't already charge ---- well, you could charge rechargable batteries with it, I guess.
You will need a charger controller, a 2 volt battery and a inverter to convert the 2volt dc to 20 volt ac. Your also going to need about 0 more solar panels of the same size!
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
You don't have much power to work with there. You could hook it up to a car battery to give it a sloooooow trickle charge. One amp will take like 60 hours of sunlight to completely charge a car battery. You'll be able to power small radios, ones that need nine to twelve volts or so. Just position the panel a bit away from the direct to the sun angle for your 9-volt radios, right at the sun for 2-volt radios. I would not try to power any AC adapters. You'd have to buy a DC to AC inverter, a very small one, and the inverter would steal about half the energy.
