Product Description

Minimum Order Quantity: 10 Kilowatt

We are offering forward the best-in-class X21 Series Solar Panels to our customers. These kind of X21 Series Solar Panels have different quality specifications and features, which are described as follows:

21.5% efficiency : Suitable for the roofs where space is at its premium or where future extension can be demanded.

Maximal performance
Configured for presenting the most energy in stringent real world states, in partial shade as well as hot rooftop temperatures.

Premium aesthetics
X-Series Solar panels combine harmoniously into your roof. This is one of the most elegant picks for your home.

Engineered for peace of mind
Organized to deliver consistent, hassle-tree energy over a much lengthy lifetime.

Designed for durability
The Solar Cell is the cell that is assembled on a solid copper basis. Virtually impermeable to the cracking and corrosion that demean Conventional Panels.
Identical superior durability as E-Series panels. #1 Graded in Fraunhofer durability examination 100% power preserved in Atlas 25+ all-inclusive PVDI Durability testing.

Highest Efficiency
Yield more energy per square foot X-Series Solar Panels change more sunlight to electrical energy making 44% more power per panel, and 75% extra energy in every square foot over 25 years.

Highest Energy Production
Make more energy per rated power unit. One year performance offers 8-10% additional energy in every rated watt. This vantage increases over time, offering 21% extra energy over the initial 25 years to meet your demands.
