Solar laptop power

Published Date 3/28/12 8:22 PM

This is a new 32W panel which is more than my older 25W panel, and runs a bigger laptop

Rugged folding 32.2W solar panel. 18 to 20VDC open circuit voltage. Current 2.4A in full sun. Cigarette socket connector. 16″ X 10″ folded; 14″ X 44″ unfolded. 1 1/2 inches thick folded. 6 pound 4 oz weight. Eyelets at each corner and at panel middle to allow mounting or suspension with rope or bungee cords. Very durable and rugged. Ripstop camouflage nylon enclosure. Take this panel anywhere. No glass. Advantages over thin film: open circuit voltage 18-22VDC (thin film tends to be 15 to 16VDC, as panel heats in sun or if in hot climates voltage for thin film panels drops and you may not charge efficiently or at all). Also thin panels are much less efficient. Substantially larger area for comparable outputs.

This is a 7AH lead acid battery, it is used as a voltage buffer and as a reservoir of power. The cables are a 240v inverter, AA battery charger, Volt meter.

This is a much bigger laptop (14.1″ and i5 proceser) than my usual solar setup, we can eather charger OR power but not both at the same time.
