A simple way to buy 400 W of Renogy’s 200 W panel for an RV roof, shed or ground mount with an MPPT controller. Compare it with two singles first, since the pack is not always cheaper.
Amazon $365.99 Renogy $352.99
A good single-panel choice for an RV roof, shed or ground mount where you want 200 W from one module. Pair it with an MPPT controller; on a 12 V system with a PWM controller, two 100 W panels make more sense.

- One panel does the work of two 100 W panels, so fewer mounts and connections on the roof
- Higher 31 V operating voltage cuts cable losses on long runs to the controller
- 10-year workmanship warranty, double the usual 5 years
- A 24 V-class panel: charging a 12 V battery needs an MPPT controller, not a cheap PWM one
- At 23 lb and about 50 x 30 in it takes two people to lift onto a roof
- No independent output test yet
