SoloPower SP3L-160 160W Flexible CIGS Solar Panel 86.5in MC4 RV Boat Camping

SoloPower SP3L-160 160W Flexible CIGS Solar Panel 86.5in MC4 RV Boat Camping

The SoloPower SP3L-160 is a 160-watt flexible, rollable thin-film solar panel built on CIGS (Copper Indium Gallium Selenide) cell technology with an ETFE top sheet. At 86.5 inches long and 45.1 inches wide — and weighing just 13.2 lbs — it is significantly lighter and more flexible than conventional glass-framed panels. This is a rare triple-wide CIGS panel from SoloPower's Portland, Oregon facility, offered here as new old stock following the company's closure in 2019. Panels were never sold commercially but may have cosmetic scuffs or scrapes from internal facility testing. The manufacture date is not known.

Applications

CIGS thin-film solar panels like the SP3L-160 are used in off-grid and mobile power systems where weight, flexibility, and low-profile mounting matter. The rollable, non-rigid design makes them well suited for RV rooftop installations, boat decks, camper vans, and remote cabin or backup power setups where traditional glass-framed panels are impractical. CIGS cells generally perform better than conventional silicon panels under low-light and indirect-angle conditions, making them useful for installations where the panel is not always at an optimal sun angle. The 65.1V Vmp places this panel in the range suitable for MPPT charge controllers in 24V or 48V battery systems. The non-penetrating, adhesive, or strap-mount approach common with flexible panels avoids the need to drill through a vehicle roof. SoloPower was a U.S. manufacturer based in Portland, Oregon, known for producing large-format rollable CIGS panels primarily for commercial and industrial rooftop applications; the SP3L series was their consumer/prosumer product aimed at mobile and off-grid markets before the company closed in 2019.
