A good fit for a 24 V cabin, tiny-home or camper system with an MPPT controller. Owners of 12 V PWM setups should take the regular MEGA 250 instead.
Amazon $269.99The Rich Solar MEGA 250 PRO 24V and the Rich Solar MEGA 250 are evenly matched, rated 3.6 and 3.6.

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.
