18V output Voltage
Unlike 12V solar panels, you only need a single one of our 18V panels to effortlessly charge your 12V battery through a controller -- a key advantage over standard 12V panels.
High-quality Pure Copper Wire
Built for the heat. Our pure copper wiring stays cooler and delivers stronger current in summer than copper-clad aluminum cables.
Superior Quality and Refined Craftsmanship
Our solar panels are built to a higher standard of quality with more precise manufacturing and finishing.
Enhanced Protection
The wiring features a unique two-layer protection system (an outer UV-resistant layer and an inner insulation layer).
Customer Feedback
Our solar panels came very well packaged for a safe delivery.
Our solar panel also includes reverse current blocking diode junction boxes to ensure it does not drain your battery after the sun goes down.

The edges are so smooth that they can't cut your bare hands while handling them.
Q&A
What do off-grid and on-grid mean?
Off-grid systems use batteries and work independently. On-grid systems connect to utility power, letting you save through net metering and maintain backup reliability.
Why is my solar panel underproducing?
A solar panel may be underproducing due to temporary factors such as shading or weather, or to issues such as dirt, a poor angle, or routine cleaning. System checks can typically restore performance.
How should I connect solar panels in my electrical circuit (series vs parallel)？
Use series wiring for higher voltage or parallel wiring to reduce shading loss. Ensure the configuration matches your inverter's voltage and current requirements.
What is the meaning of 12V in the product title? Why is this value different from the voltage of the solar panel？
When you open the product page, you will see a title like "xxx Watt 12V Solar Panel." The "18V" in the product title indicates that this solar panel is suited for an 18-volt system. Its actual operating voltage (VMP) is higher, which is necessary for efficient charging.
