A 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.
Amazon $59.99 JJN $59The JJN 100W 12V 10BB Monocrystalline Rigid Solar Panel is the better rigid solar panel overall, rated 4.1 to 3.9. The JJN 100W 12V 10BB Monocrystalline Rigid Solar Panel leads on value. The Renogy ShadowFlux 120W N-Type Anti-Shading Rigid Solar Panel wins on efficiency and durability. The JJN 100W 12V 10BB Monocrystalline Rigid Solar Panel costs $69.24 less ($59 vs $128.24).
For 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.
