Homemade Solar Powered Battery Charger. very simple design. only 3 items needed, 1 small solar panel, plastic battery cradle, rechargeable batteries. powerful fast charge. easy to make. for charging 2 to 4 AA AAA C or D size batteries. use a 6v 1.5 watt panel. that will produce 250mah of current per hour. you can also use a 6v .5 watt or 6v 1 watt panel. those will charge the batteries slower but will work
