The HQST 100W 12V 9BB Monocrystalline Rigid Solar Panel is the better rigid solar panel overall, rated 4.1 to 3.9. The HQST 100W 12V 9BB Monocrystalline Rigid Solar Panel leads on value. The Renogy ShadowFlux 120W N-Type Anti-Shading Rigid Solar Panel wins on efficiency and durability. The HQST 100W 12V 9BB Monocrystalline Rigid Solar Panel costs $78.25 less ($49.99 vs $128.24).
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.
Amazon $49.99 HQST $49.99For a van or small RV roof where vents, racks or trees shade part of the panel. With clear sun all day, a standard 100 W panel costs less per watt.
