The Renogy 100W N-Type Bifacial is the better rigid solar panel overall, rated 4.0 to 3.7. The Renogy 100W N-Type Bifacial leads on value. The Renogy 100W N-Type Bifacial costs $20 less ($99.99 vs $119.99).
A compact, well-documented 100 W panel for a van or small RV roof with an MPPT controller. Buyers on a 12 V PWM setup or a tight budget are better served by a cheaper 18 V panel.
Amazon $99.99The panel to buy when a van or RV roof only has a long, narrow gap to fill. Where a standard 100 W panel fits, it costs much less.
