The Renogy 100W N-Type Bifacial is the better rigid solar panel overall, rated 4.0 to 3.8. The Renogy 100W N-Type Bifacial leads on durability and efficiency. The JJN 100W 12V Rigid wins on value. The JJN 100W 12V Rigid costs $40.99 less ($59 vs $99.99).
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 $99.99A cheap 100 W panel for a small 12 V system on a van, boat or shed. JJN’s newer N-type 100 W panel is the more efficient choice if the price gap is small.
