Q Peak Q Cells review

Q CELLS Q.Antum Q.PEAK Solar Panel Cell Technology

High-performance technology for durability; Q CELLS premium solar panels with Q.ANTUM technology give maximum output and reliability.

Q.ANTUM technology supercharges ordinary crystalline solar cells and modules. No special system components are required. Q.ANTUM delivers exceptional performance under real-world conditions in Q CELLS Q.PEAK solar panels.

Q.ANTUM was designed to generate more power when the sun is rising, setting, or even behind clouds. Higher solar power yields will be acheived in the middle of hot and sunny summers, and during clear fall and winter days, when the sun is not as high in the sky.
