Ultra Lightweight 21kg Monocrystalline Solar Panel 420W with Slim 30mm Anodized Aluminum Frame

21kg Ultra Lightweight 420W Monocrystalline Solar Panel

The KUOMAN KS-420M-SL is engineered for applications where weight matters. At just 21.0 kg approximately 25% lighter than conventional 400W+ panels this 420W monocrystalline module significantly reduces roof structural loading, shipping freight costs, and on-site handling effort. The slim 30mm frame profile maintains full structural integrity while shedding unnecessary mass.

Weight Optimization Benefits

• 21.0 kg Total Weight: One of the lightest 400W+ monocrystalline panels on the market, reducing per-panel roof loading to just 10.7 kg/m2.
• 30mm Slim Frame: Thin-profile anodized aluminum frame reduces material usage without compromising 3600Pa snow load and 2400Pa wind load ratings.
• 2.8mm Front Glass: Strategically selected thinner tempered glass with full AR coating saves 1.5 kg versus standard 3.2mm glass while maintaining impact resistance.
• Lower Freight Cost: Lighter panels enable 36 panels per pallet (versus 31 for standard weight) and reduce container weight for lower shipping fees.
• Faster Installation: Single-person handling capability reduces labor time and safety risks on residential rooftops.
• Ideal for Aged Roofs: Perfect for retrofit installations where existing roof structures have limited additional load capacity.
