ARMORCELL is ChargeSys's proprietary technology designation for our engineered CIGS solar assemblies. Every ARMORCELL panel uses ETFE (ethylene tetrafluoroethylene) film as the outer surface rather than the lower-cost PET film competitors use — ETFE is UV-transparent, near-zero moisture permeability, and holds up in harsh environments for 10–20 years where PET delaminates in 3.

Quality CIGS panels are rated for 20–25 year operational lifespans with typical power degradation under 0.5% per year. All self-adhesive ARMORCELL products are backed by a ChargeSys 5-year warranty; portable kits carry 3 years.

Weight and vibration tolerance are the two big ones. A 160W ARMORCELL panel weighs about 6 lbs vs. 25–30 lbs for a comparable glass-and-aluminum panel. That means no rails, no drilled holes, and no windage on a $200,000 ambulance. And the CIGS thin-film construction is inherently vibration-tolerant — laser-scribed cells don't develop the microcracks that end crystalline panels on mobile installs within a few years.

Yes — panels generate power from diffuse (indirect) sunlight, not just direct rays. Output is reduced proportionally to light intensity. CIGS thin-film actually performs better in overcast and partial-shade conditions than crystalline silicon, which needs a certain intensity threshold before it starts producing.

Yes — ARMORCELL panels without aluminum frames and glass are inherently better suited to marine environments. They're IP68 sealed against immersion and salt spray, walkable so deck-mount installs don't need a "keep off" policy, and bond flat to the deck or bimini with no rails, brackets, or through-hull hardware that corrodes.

For most applications, yes. The self-adhesive kits are peel-and-stick and take one person under an hour: bond the panel to the roof, run the wire through the supplied gland, connect through the breaker/fuse to the battery via the MPPT controller. Portable kits are even simpler — unroll and clip to the battery.

For ambulance and emergency-vehicle applications, we recommend a licensed electrician or the OEM upfitter do the electrical connection so the install is signed off against your vehicle's spec.
