Solar Panel 18V 5W
The 18V 5W solar panel is a compact, rugged photovoltaic module for low-power applications. It uses high-efficiency monocrystalline silicon cells laminated under toughened (tempered) glass, creating a rigid, durable surface.
The cells are mounted on a lightweight backsheet within an aluminum frame, making the panel weatherproof (resistant to moisture, UV and scratches) and suitable for long-term outdoor use.
Its small footprint allows easy mounting on fences, rooftops or portable rigs. In bright sunlight it generates roughly a few watts of power (enough for trickle-charging a 12 V battery or running tiny electronics), and it still produces some current in low light. The panel has no moving parts, so it operates silently and requires virtually no maintenance, with a multi-year service life.
Overall, this 18V 5W panel offers a simple, reliable source of renewable energy for remote or off-grid settings, DIY solar projects, or educational kits.
Features:
- High-efficiency solar cells: Uses premium monocrystalline PERC silicon cells for maximum energy conversion.
- Tempered glass laminate: Solar cells are protected by toughened glass, giving the panel a rigid, impact-resistant surface.
- Weatherproof construction: The panel is designed to be waterproof, UV-resistant and scratch-resistant for outdoor durability.
- Sturdy aluminum frame: A rigid metal frame encloses the panel, providing structural support and easy mounting points.
- Compact, lightweight design: Its small form factor and low weight make the panel easy to carry and install in tight spaces.
- Maintenance-free operation: With no moving parts, the panel runs silently and requires virtually no upkeep.
