A strong single panel for a 12 V RV, van or boat roof where space is tight and the controller is PWM. Buyers with room for two panels can get the same power for less.
Amazon $269.99The Rich Solar MEGA 250 is the better rigid solar panel overall, rated 3.6 to 3.2. The Rich Solar MEGA 250 leads on value and efficiency. The Rich Solar MEGA 250 costs $60 less ($269.99 vs $329.99).
For van and RV owners whose roof only has long, narrow gaps to fill. Anyone with room for standard-width panels gets far more watts for the money.
