Monocrystalline Silicon, Low Iron Glass, Anodized Aluminum are the materials used in the construction of these solar panels. The product dimensions are 35.24L x 23.03W x 1.38H. These panels are classified as high efficiency, with each panel capable of producing a daily output of 1600wh under the condition of 4 hours of sunlight. The use of PERC technology enhances cell efficiency to 23% by improving sunlight reflection and utilization. Each panel is equipped with 35-inch cables and features bypass diodes pre-installed in a waterproof junction box, which is rated IP65. This design minimizes power drop caused by shade and ensures excellent performance even in low-light environments. These panels are suitable as a basic generator component for 12V/24V battery charging in various power systems, including on-grid, off-grid, and hybrid systems for home, garden, RV, boat, and agricultural use. They can also be used to extend existing systems. The panels are lightweight and designed for effortless installation, even for beginners. They come with plug-and-play connectors and pre-drilled holes on the back, allowing for quick installation on roofs or brackets. The 1.38-inch thickness of the panels aids in rapid heat dissipation for stable performance, withstands harsh weather conditions due to their sturdy construction, and facilitates easy installation. The complete set of 4 panels is packed across two individual boxes for optimal protection, and customers are advised to wait for the second box to arrive.
