                                                          300 Watt Mono Solar Panels for Your Rooftop


The 300 watt mono crystalline Solar Panel is the ideal source and cost-effective solutions to covert your house from an energy dependant home to an energy producing location. Whether you want to connect it to the power grid, or use it to power off-grid system, solar panel is perfect for decreasing your home electricity bill.

High Efficient Cell Technology
Driven by the new cell technology, our high efficiency modules will provide customers with high economic benefits. 

Light and Robust
With a weight of just 21.6 kg, our solar modules are proven to demonstrate outstanding durability against external pressure up to 5400 Pa.

100% EL Test Completed
All our solar panels pass Electroluminescence inspection. This EL inspection detects cracks and other imperfections unseen by the naked eye.


Reliable Warranties
* Bypass diodes guarantee the module free of overheating and ‘hot spot effect’.

* TPT back sheet ensures smooth performance over a long period of time.
* We offer a 10 year product limited warranty and a 25 year limited linear output warranty. 


* Guarantee from 0 to +3% as power tolerance to ensure high reliability of power output.

* Salt mist corrosion tested, perfect for harsh climatic conditions.

* Anti-reflective, high transparency, tempered low iron glass service life is as long as 25 years.

* Waterproof junction box provides complete protection against environmental particles and low pressure water jets.


* Can be used for many different applications, e.g., residential and commercial rooftop systems.

* Commercial, industrial and Utility large-scale ground mounts.

* Compatible with on-grid and off inverters systems.

Easy Installation
Our solar modules are carefully designed to benefit installers by allowing quick and easy installations throughout the carrying, grounding, and connecting stages of modules.
