Lumera Solar 140W “Long & Skinny” BiFacial 12V Solar Panel | Canadian Made

Lumera Solar 140W Bifacial 12V Solar Panel

The Lumera Solar 140W Bifacial 12V Solar Panel is a compact, narrow-format solar module designed for installations where conventional panel dimensions are difficult to accommodate. Its long and narrow profile makes it particularly well suited for RV roofs, camper vans, boats, trailers, and other applications where vents, roof equipment, or curved surfaces limit available mounting space. Lumera specifically identifies this 140W “Long & Skinny” module for RV and marine installations.

Manufactured in British Columbia, Canada, the panel combines monocrystalline solar cells with bifacial construction, allowing solar energy to be collected from both the front and rear surfaces. Lumera states that backside generation and internal reflection can provide up to 30% additional energy under suitable installation conditions.

With a rated output of 140W, 19.8V maximum power voltage, and 7.05A maximum power current, the panel is well suited for 12V battery charging systems when paired with an appropriately sized solar charge controller.

Designed for RV, Marine & Mobile Solar

At only 390mm (15.35 in.) wide, the panel provides a practical way to add solar capacity to roofs with limited uninterrupted mounting space. Its approximately 1.7m-long format can fit alongside roof vents, air conditioners, antennas, and other equipment where a conventional wider module may not fit.

Lumera identifies this model as its “Lux Skinny” panel and notes that it is intended for RVs, boats, rounded roofs, and other installations where conventional panel geometry is restrictive. Factory MC4 leads are provided to simplify connection into standard PV wiring systems.

Bifacial Solar Technology

Unlike a conventional monofacial module, a bifacial panel can convert solar radiation reaching both the front and rear surfaces into electrical energy. Reflected sunlight from light-coloured roofs, ground surfaces, or other reflective materials can therefore contribute additional production.

Actual bifacial gain depends on installation height, mounting geometry, shading, surface reflectivity, solar angle, and site conditions. Lumera states that the panel can produce up to 30% additional energy from its bifacial construction under suitable conditions.
