About This Item

• 21% Monocrystalline Efficiency: High-purity monocrystalline silicon cells achieve 21% conversion efficiency — producing maximum power output from a minimal surface area. Significantly more efficient than polycrystalline alternatives at the same price point.
• 100W / 12V for All Standard Applications: Perfectly sized for 12V battery charging systems in RVs, boats, cabins, sheds, and off-grid solar installations. Connect multiple panels in series (24V, 48V) or parallel (higher current) for larger systems.
• Pre-Drilled Mounting Holes + Z-Brackets: The aluminum frame includes pre-drilled mounting holes compatible with standard solar mounting hardware. The included Z-brackets allow immediate installation on RV rooftops, boat decks, or ground mounts without additional hardware.
• MC4 Connectors – Universal Compatibility: Industry-standard MC4 connectors are compatible with virtually every solar charge controller, inverter, and extension cable on the market. Connect multiple panels in any configuration without adapters.
• IP65 Weatherproof Junction Box: The sealed IP65-rated junction box protects internal connections from moisture, dust, and UV radiation. Rated for outdoor installation in all US climate zones including coastal and desert environments.
• High Wind & Snow Load Resistance: The anodized aluminum frame withstands wind loads up to 2,400 Pa and snow loads up to 5,400 Pa — tested to IEC 61215 standard for permanent outdoor installation.
• 25-Year Power Output Guarantee: Renogy guarantees minimum 80% of rated power output for 25 years — the longest power warranty in the consumer solar panel market. 5-year product defect warranty covers manufacturing issues.
