The new Solahart Silhouette® 440W bifacial solar panel, our smartest, most powerful panel ever, is taking residential solar energy to a whole new level.

Using cutting-edge bifacial technology, each panel captures the sun’s rays on both its front and back sides which increases total energy generation.*

To ensure greater durability, reliability, and safety, panels also come with dual layers of glass, while the latest N-type rectangular cell technology offers higher power output, outstanding reliability, and a superior 22% efficiency. 

For the ultimate peace of mind, the new Silhouette panel comes with an impressive 30-Year Performance Guarantee^ on top of a Solahart 30-Year Australian Product Warranty.#

Soak up more sunshine on the front and back

The new Solahart Silhouette® solar panels use bifacial cells and are constructed with glass on the front and back. This next-gen technology allows them to convert both direct sunlight, and light that’s reflected off the ground or roof, into energy. Depending on the installation angle and amount of reflection, this means between 0% to 25%* more energy can be produced compared to monofacial panels.


*The bifacial solar panel is designed to generate energy from both the front and rear sides, depending on the amount of light that reaches the rear side. The rear side light depends on factors such as the type of roof, its albedo (reflectivity), and the method of installation. The bifacial solar panel can produce between 0% to 25% more electricity than a monofacial solar panel under optimal conditions, but this is not guaranteed. The actual performance of the bifacial solar panel may vary depending on the environmental and operational conditions. Please consult a qualified installer for the best installation method and location for your bifacial solar panel.
