I have 2 x110 amphr batteries in my truck and I put a 20w panel at the than to keep them loaded, I will in the hottest days and want to know what the best type of panels? I know there are several types.

Normally, you want to charge the lead acid batteries at a rate of 5% of its capacity, or at least 3%. So in your case, you have a bank of 220 AH, and they want to charge a minimum of 6.6 or better, 11 A. The lower figure is a 100w panel, and is higher on a 200w. 20w panel is good for keeping batteries that have been uploaded already from your alternator, but being poor in batteries that are discharged to absorb load. As for the type of panel, I would see in a crystalline silicon panel, either mono or polycrystalline. The flexible panels or thin-film wear out after a couple of years, in my experience. I have a dead flexible panel on my roof to prove it, but the crystalline panels are still going strong after years.
