Description
SoloPower 1152ak Flexible Thin Film CIGS Solar Panel 3.5V 7W MC4 Connectors
The SoloPower 1152ak is a small, flexible thin-film CIGS (Copper Indium Gallium Selenide) solar panel designed for low-voltage charging and solar energy experimentation. Unlike rigid crystalline silicon panels, this panel uses a lightweight, bendable substrate that allows it to conform to curved surfaces. It has been tested at our facility and confirmed to output approximately 3.5 volts under illumination.

Applications
CIGS thin-film solar panels like the SoloPower 1152ak are used in applications where flexibility, light weight, and low-profile mounting matter more than the higher efficiency of rigid crystalline panels. At 3.5V output, this panel is well suited for trickle charging small 12V or 3.7V lithium batteries, powering low-draw sensors, or serving as a portable power source for electronics prototyping and solar energy education projects. Flexible thin-film panels are commonly used in off-grid and portable applications — backpacking, marine installations on curved deck surfaces, RVs, and UAV/drone power systems — where rigid panels cannot be used. SoloPower was a U.S.-based manufacturer that developed roll-to-roll CIGS deposition technology; panels from this production run are now primarily of interest to hobbyists, researchers, and solar educators working with small-scale CIGS technology.
This SoloPower 1152ak flexible thin-film CIGS solar panel has been tested at our facility and confirmed to output approximately 3.5 volts. The panel is in good used condition. The cell surface, flexible substrate, and black textile border frame are all intact with no visible damage. The MC4-style output connectors and junction box are present and in good condition.
