X-22 Series Solar Panel
X-22 Series Solar Panels Offer More than 22% Efficiency
Appropriate for roofs where space is superior or where future betterment might be essential.
Configured to provide the most energy in exigent real-world premises, in one-sided shade as well as heated rooftop temperatures.
Made with the freshest and most coercive technology, X-Series offers unbeaten performance and power to your home.
Our Solar Cells: Fundamentally better
Contrived for optimal performance, configured for strength.
Made for Peace of Mind
Designed to proffer consistent, trouble-free energy over an extended periood of time.
Planned for Strength
Our offered Solar Cell is the exclusive cell, which is built on a solid copper base. Nearly impervious to the erosion and cracking, which take down conventional panels. Indistinguishable excellent durability that is similar to E-Series panels. #1 Rank in Fraunhofer strength test. 100% power retained in Atlas 25+ across-the-board durability trial.
Yield additional energy per square foot
X-Series residential panels change more sunlight to electrical energy by bringing forth 38% extra power in every panel and 70% extra energy per square foot in more than 25 years.
Highest Energy Production
Provide more energy in every rated watt. One year performance makes 8–10% extra energy in per rated watt. This point increases over time, making 21% alternative energy over the preceding 25 years to meet the demands.
