450w Half Cell Solar Panel With Battery 12v Photovoltaic Solar Panel
1. Description
Solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", but the cost of production is relatively high. It is so large that it has certain limitations in its universal use. Compared with ordinary batteries and rechargeable batteries, solar batteries are more energy-saving and environmentally friendly green products.

3. Advantages
Higher Durability
The multi-busbar design can decrease the risk of the cell micro- cracks and fingers broken.
High Power Density
High conversion efficiency and more power output per square meter, by lower series resistance and improved light harvesting.
Half-cell Design
Less energy loss cased by shading due to new cell string layout and split J-box, and lower cell connection power loss due to half-cell design.
Advanced Glass
Our high-transmission glass features a unique anti-reflective coating that directs more light on the solar cells, resulting in a higher energy yield.
