Description
SoloPower SP1-70 70W 22V Flexible CIGS Thin Film Solar Panel MC4 Rooftop
The SoloPower SP1-70 is a 70-watt flexible thin film solar panel using CIGS (Copper Indium Gallium Selenide) photovoltaic technology. At just 4.6 lbs and 2.0 mm thick, it rolls up for transport and lies flat against rooftop surfaces without frames or ballast. MC4 connectors are positioned on opposite ends of the panel for straightforward series or parallel wiring into a solar array.

Applications
CIGS thin film panels like the SP1-70 are used in rooftop solar installations where weight and profile matter — low-slope commercial rooftops, metal standing-seam roofs, and building-integrated photovoltaic (BIPV) applications where a rigid glass panel would be too heavy or structurally impractical. The flexible substrate conforms to curved or uneven surfaces and bonds directly to roofing membranes, eliminating the need for racking hardware. The SP1-70 is also used in off-grid and remote power systems where shipping a lightweight, rollable panel is a practical advantage. SoloPower developed the SP1 series specifically for large commercial rooftop deployments and manufactured these panels in San Jose, California during the early 2010s, a period of significant investment in domestic thin film solar manufacturing.
This SoloPower SP1-70 70W flexible CIGS thin film solar panel is unused and was manufactured at SoloPower's San Jose, California facility. It came directly from their QC department and has been tested to output voltage. Note that most of these panels have writing or markings on them from their use in QC testing — this is normal and does not affect performance. We have had multiple units in stock; the unit you receive may vary slightly from the one photographed but is functionally equivalent. Please view our photo set and contact us if you have any questions.
