450 Watt Solar Panel Features

Half-Cut Technology

Equipped with half-cut solar cell technology, this panel effectively reduces energy loss due to shading and temperature variations. Each cell is split into two sections, allowing for higher energy production even in partially shaded areas.

Performance in Low-Light Conditions

Monocrystalline solar panels perform better than polycrystalline panels in low-light conditions. This makes them an excellent choice for locations with limited sunshine or shady areas. Even on cloudy days or during the evening hours, monocrystalline solar panels can still generate electricity, ensuring consistent performance throughout the year.


The panel is constructed with high-quality materials that ensure longevity and resistance to wear and tear. It can withstand challenging environmental conditions, including extreme temperatures, humidity, and heavy snow loads.

Advanced Glass

The anti-reflective and anti-soiling coated glass surface not only enhances light absorption but also reduces maintenance requirements by preventing dirt and debris from sticking to the panel.

High Efficiency

The monocrystalline solar cells used in this panel are famous for their high conversion efficiency, enabling them to maximize energy production from available sunlight.


We offer a comprehensive warranty to give you peace of mind. The product comes with a 25-year linear power output warranty, ensuring long-term performance and reliability.

Easy installation

The panel comes with a standard mount and interface, making it easy to install and integrate with other solar systems.
