Lightweight PV
Flexible Solar Panel
520W power in a light, adhesive-mounted module for roofs that cannot take heavy racks or new penetrations.
Discuss a Roof Project520W Flexible Module
High-output PV without heavy glass, rails, or roof penetrations.
Convol Energy flexible PV modules are built for roof surfaces where conventional framed glass panels and rail systems add too much weight, require too many penetrations, or conflict with roof warranty requirements.
The 520W module uses 182 half-cut monocrystalline cells in a thin, frame-free package. It delivers high output in a near 4 ft x 8 ft class footprint while keeping module weight to 11.5 kg.

Why It Matters
Designed for roofs where conventional PV creates installation risk.
Power density close to mainstream glass PV
At 520W and 19.3% STC efficiency, the module provides practical roof output without requiring a heavy glass-and-frame package.
Very low roof load
At 11.5 kg per module, the panel reduces dead load on roofs and can avoid the weight of conventional rails, clamps, and ballast.
No roof penetrations
Adhesive mounting avoids drilling through shingles, membranes, or metal roof panels, reducing leak risk and helping protect roof warranty conditions.
Bonded installation
The frame-free module is designed for adhesive attachment to approved roof surfaces after proper cleaning, preparation, alignment, and cure time.
Wind-tested installation approach
When installed with the specified bonding process on approved substrates, the system has been tested for resistance to 100 mph wind exposure.
Corrosion-resistant field use
The glass-free, frame-free construction and IP68 electrical components support installations in coastal and corrosive environments.
Roof Protection
No drilling through the roof surface.
Adhesive mounting helps keep the waterproofing layer intact. For retrofit work, that means fewer leak paths, less structural load, and a cleaner discussion with roofing contractors and warranty providers.
