💁Product Features

📀High Efficiency：500 watt solar panels adopt the 9BB solar panel cell design and are made of excellent Grade A cells. The conversion rate is as high as 22% and can provide about 500 Wh of electricity per day (depending on sun availability). Compared with 5BB and Grade B solar panel cells, it has better quality and efficiency.

📀Upgraded Design：Monocrystalline solar panel upgraded the latest half-cut cell technology, which makes the solar panels obtain better and more stable performance. Compared to regular solar panel, half-cut cell technology can reduce power loss, lower solar panel temperature and reduce the impact of shading on performance.

📀Durable Solar Panel：Our 18V 500 watt solar panels feature a corrosion-resistant aluminum frame. It can also withstand strong winds of 2400Pa and Snowload of 5400Pa. Both the IP65 junction box and IP67 MC4 connectors have excellent waterproof functions. Allows you to use it outdoors with confidence.
