Rich Solar MEGA 250 PRO 24V
#48 in 150 W and upFull review
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.

3.4/5
For a van roof where a 175 W panel fits better than a 200 W one, on a 12 V system with a simple controller. Where space allows, a 200 W N-type panel gives more for the money.

Pros
- Sized at about 50 x 27.5 in to fit a Sprinter-type van roof
- An 18 V operating voltage charges a 12 V battery with an inexpensive PWM controller
- 10-year materials and workmanship warranty, double the usual 5 years
Cons
- Lower module efficiency (19.8%) than newer N-type panels, so it is larger and heavier per watt
- Costs more per watt than most 200 W panels
- No independent output test yet
