Connect timer w Rechargeable 9v to Solar panel?
I am using a rechargeable 9v battery in my irrigation timers. I would think it would be easy to hook up a small solar panel to charge the batteries during the day and then I don't have to worry about them failing and me not noticing until my garden goes brown. Two wires join in a pastic coated cap that hooks to the 9volts. Can't I just take the cap apart and connect the leads from the little solar panel?
