Find the right panel for your deck or roof
Flexible, rigid, or bifacial — and how many watts. Here's the lineup we stock for boats, vans, RVs and off-grid, all sized to pair with a Victron MPPT controller.

Every panel needs a charge controller — pair it with a Victron MPPT and size the match with our MPPT sizing calculator. Need the wiring and mounts? See solar cables & accessories. (Charging a Torqeedo Travel/Ultralight motor instead? That solar charger lives with electric outboards.)
How to choose, in three questions
Panel type, how many watts, and the one part you can't skip.
Flexible, rigid, or bifacial?
Flexible panels are thin, light and can curve to a deck or roof — ideal where weight and shape matter. Rigid framed panels are the most durable and efficient per dollar for a flat, fixed mount. Bifacial panels also harvest light reflected onto their back surface, a nice bonus over a light deck or the water.
How many watts do you need?
Add up your daily amp-hours and work back. A rough starting point: 100W of panel makes on the order of 30–40Ah on a good day, less in clouds or winter sun. Roof or deck space and shading usually set the ceiling. Our calculator helps match panels to a controller.
You'll need a charge controller
Never wire a panel straight to a battery — a charge controller regulates it safely. A Victron SmartSolar MPPT harvests noticeably more than a basic PWM unit and adds Bluetooth monitoring. Size the controller to your panel wattage and battery voltage.

Solar panel FAQ
Flexible or rigid panels — which is better?
Neither is universally better. Flexible panels are light, low-profile and can follow a curved deck or roof, which is why they're popular on boats and vans — the trade-off is they generally don't last as long as glass-and-frame panels and can run hotter. Rigid framed panels are the most durable and efficient per dollar when you have a flat surface to mount them.
What does bifacial mean?
A bifacial panel generates from both faces — the front from direct sun and the back from light reflected off whatever's beneath it. Over a light deck, sand or water you can pick up extra output. Gains depend on how reflective the surface is and how the panel is mounted.
How many watts of solar do I need?
Work back from your daily energy use. A loose rule is that 100W of panel yields roughly 30–40Ah on a sunny day (less in clouds or winter), so add panels until you cover what you draw, within the space you have. Our MPPT sizing calculator helps you check panel-to-controller fit.
Do I need a charge controller?
Yes — a panel must go through a charge controller, never straight to the battery. A Victron SmartSolar MPPT typically harvests more than a basic PWM controller and lets you monitor everything over Bluetooth. Size it to your panel wattage and battery voltage.
Can I mix different panels?
It's best to keep panels in a series string identical, since the weakest panel can limit the rest. Different panels are better wired in separate strings or with their own controllers. If you're combining odd sizes, ask us and we'll lay out a wiring plan that doesn't leave output on the table.
12V or 24V panel configuration?
Some panels (like the Lumera 220W bifacial) offer a 12V or 24V wiring configuration. Match it to your battery bank and controller plan — higher-voltage strings can reduce wiring losses on long runs. We'll help you pick the right config for your system.
