GRANKIA GMH550W 144 half-cut cell mono silicon 550 watt solar panels aree significant leap in the evolution of solar energy technology. The parallel wiring of half-cut cells minimizes energy loss, making 550 watt solar panels more efficient in converting sunlight into electricity. This translates to higher energy production and quicker return on investment. Half-cut cells are more resilient against micro-cracks and hotspots, ensuring that the solar panel system remains reliable and efficient over its lifetime.

Half-cut cell mono silicon 550 watt solar panels are an innovative design that addresses some of the challenges faced by traditional solar panels. In a standard solar panel, solar cells are connected in series, meaning that the performance of one cell can affect the entire panel.

550 Watt Solar Panels 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.

Better Shading Tolerance

Shading on a traditional panel can significantly impact energy production. With half-cut cells, shading on one part of the panel does not affect the performance of the rest, making them an ideal choice for installations in partially shaded areas.

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.
