Laptop Solar Panel Charger Help Please?

We Answered:

its only a 2 watt panel, it will take quite a few hours to charge anything from flat, and that assumes constant bright sunshine which we dont get in the UK

Solar panel and charger for a 6v 9.5 AH battery?

We Answered:

6 volt SLE battery will require 7.2 volts to charge and a minimum of 15 solar cells.
I don't understand, do you want the solar panel on the F-150 as well ?

next you need to determine the size of each cell you can allow room for
larger size cells offer more current, and will charge the battery faster.

Aluminum angle, polycarbonate sheets, rivets, drill, 1 diode, and a soldering iron.

ebay solar cells can be for for under $0.75 per watt with a 6"x6" cell @ 8 amps output

Under sunny conditions this type of system could charge your battery in under 2 hours.
