220W Lumera BiFacial Solar Panel LS220WM10

Lumera 220W Bifacial Rigid Solar Panel Upgrade your solar setup with a Canadian-made 220W bifacial rigid solar panel from Lumera Solar. Built with modern M10 monocrystalline cells, multi-busbar design, tempered glass, and a black anodized aluminum frame, this panel is a strong fit for RVs, vans, cabins, sheds, marine installs, off-grid systems, and compact rooftop solar arrays. We offer two electrical configurations in the same physical panel size: the LS220WM1012V traditional lower-voltage version and the LS220WM1024V higher-voltage version. Both are 220W bifacial panels, featuring the same M10 cells, overall dimensions, MC4 connectors, and 25-year linear performance warranty. The only difference is the voltage they operate at. Conservative Power Ratings Unlike many brands that advertise aggressive “best case” wattage figures, Lumera uses conservative published ratings designed to deliver reliable real-world performance and exceed customer expectations. The result is a panel built for dependable output, long-term satisfaction, and confidence in everyday use. Why You’ll Love This Panel Tests at 230W output! Bifacial design captures reflected light on the rear side for additional energy production above the ratings. Modern M10 monocrystalline cells with multi-busbar construction for increased efficiency and performance. Two voltage options for easier matching with different solar charge controllers and system designs. Durable rigid construction with tempered glass and a black anodized aluminum frame. Locally supported 25-year linear performance warranty from a Canadian manufacturer. Made in Canada Manufactured locally by Lumera Solar in Surrey, British Columbia — Western Canada’s only solar module manufacturer.

Solar Panel Shipping Note Solar panels are oversized items and may require additional shipping fees depending on destination and order size. We do our best to keep these costs fair and will contact you before shipment if a surcharge applies. Frequently Asked Which version should I choose: LS220WM1012V or LS220WM1024V? The LS220WM1012V is the more traditional lower-voltage version, with a Voc of 21.86V and Vmp of 18.78V. This is often the easier choice for simple 12V battery systems, small RV or trailer installs, portable solar setups, and lower-voltage charge controllers. It also gives you more flexibility when wiring panels in series because each panel adds less voltage to the string. The LS220WM1024V is the higher-voltage version, with a Voc of 43.72V and Vmp of 37.56V. This version can be a better fit for MPPT charge controllers that prefer higher PV input voltage, longer wire runs where reducing current can help reduce voltage drop, or systems where you want useful charging voltage from a single panel into a 24V battery bank. As a general rule, choose the lower-voltage 12V version for simple 12V systems and maximum series-wiring flexibility. Choose the higher-voltage 24V version when your controller’s PV input rating supports it or you specifically want lower current, higher voltage. Always confirm your charge controller’s maximum PV input voltage, especially in cold weather, because panel Voc rises as temperature drops. If you are unsure, feel free to contact us with your design ideas/goals, and we'll help you decide. Are both panels the same physical size? Yes. Both versions use the same 1436mm × 768mm × 35mm frame size and the same 220W bifacial rigid panel format. The only difference is the internal electrical configuration, which changes the voltage and current output. Please be aware that these panels are slightly larger than the previous M6 model of the 220W panels. Can I mix the 12V and 24V versions together? Generally No. It is usually best not to mix different voltage/current panel versions in the same string or parallel group unless the system has been carefully designed for it. Mismatched panels can create performance & design issues. For most systems, choose one version and keep the array consistent. If you need to mix panel types/sizes/ratings for your installation, it's recommended to use separate charge controllers for each type. Is this panel good for RV, van, cabin, or marine use? Yes. This compact 220W rigid panel is well suited for RVs, vans, trailers, cabins, sheds, marine solar setups, and other off-grid applications where durable construction and efficient output are important. The panels are constructed to be sealed against all elements, and durable enough to survive extreme weather or vibration. This makes them well suited to mobile or stationary installations. Does bifacial output mean the panel always produces more than 220W? The 220W rating is the front-side STC rating. Bifacial panels can produce additional energy from reflected light reaching the rear side, but the actual gain depends on mounting height, surface reflectivity, tilt angle, available sunlight, and installation conditions. It is very possible to exceed the 220W rating when the panel is exposed to full sunlight from the front, as well as reflected light at the back.
