PowerFilm Foldable Solar Panels

Compare wattage and voltage together

For the 120W models, compare the 15.4V version with the 30.8V version. The same wattage does not make these interchangeable. The 220W options also come in 15.4V and 30.8V configurations; verify the exact model before ordering.

Check the panel's open-circuit voltage against the receiving equipment's maximum input, as well as its permitted operating-voltage range, current and wattage. Include any manufacturer-required cold-weather voltage allowance. A matching plug does not establish electrical compatibility.

Thin-film or crystalline?

The range includes amorphous thin-film blankets and the 160W crystalline solar blanket with SAE connector. Compare folded size, weight, deployed footprint and electrical specifications on the individual product pages. The crystalline model has a different voltage profile from the 15.4V blankets.

Check the complete charging connection

For battery charging, select a charge controller suitable for the panel output and battery chemistry unless the exact panel and battery manufacturers explicitly permit your proposed direct connection. For a power station, verify its built-in solar controller's limits and the required adapter. Confirm connector polarity, cable ratings and which accessories are included; packages differ by model.

Plan for real outdoor output

Rated watts are measured under test conditions, not a promise of continuous production. Sun angle, shade, weather and temperature affect what reaches the battery. Allow for charging losses and a backup plan when estimating daily energy.

These panels are for portable deployment, not permanent outdoor installation. Dry them before folding and storage, and follow the exact model's care instructions. Consult PowerFilm's foldable-panel instructions alongside the model specification sheet.
