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 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 HQST 100W 12V Rigid wins on value. The HQST 100W 12V Rigid costs $50 less ($49.99 vs $99.99).
The budget pick for a shed, gate opener, small cabin or ground mount where space isn’t tight. On a crowded van roof a smaller N-type 100 W panel is the better fit.
