Title: Solar Panels............
Post by: Ranger3/75 on Apr 21, 2009, 06:10 AM
Has anyone used or tried the "solar panels"that Walmart sells on their website,as well as Coleman website.They seem to have good reviews and dont require alot of hookup.I know they arent as strong as the larger units,but seems like for a PUP,they would be fine for keeping the battery charged...

Ranger, save your money...those little things might maintain a charge if the battery is sitting in between use.  We never really got down and dirty calculating our use, but we are generally light on the battery use and wouldn't go with any less than 45 watts.

45W should be the minimun. Power = W/V
45W/12V= 3.75A at 100% efficiency

Dead battery = 50AH short at 50% of a 100AH battery and this = 13.3 hours of charge time.

How do I know?
