Key features

  • Higher Module Efficiency
  • High Efficiency in High Temperatures
  • Heterojunction Cell Technology with Gapless Connections
  • Durability & Quality Assurance
  • Improved Performance When Shaded

Higher Module Efficiency

Superior module efficiency of 21.1%, allows maximum power production with less roof space. Offering clean aesthetics and one of the industry’s lowest annual degradation rates, power output of at least 92% is guaranteed after 25 years.

AllGuard and TripleGuard 25-Year Warranty

A long-term warranty is only as reliable as the company behind it. AllGuard and TripleGuard 25-year warranties cover EVERVOLT panels for performance, product, parts and labor for 25 years. Whether in year three or year 25, your Panasonic warranty will be there when you need it1.

High Efficiency in High Temperatures

Produce more energy throughout the day even on the hottest days in the warmest climates. EVERVOLT solar panels outperform others when temperatures rise due to our industry-leading 0.26%/°C temperature coefficient.

Heterojunction Cell Technology with Gapless Connections

Half-cut cells with heterojunction technology with gapcell connections minimizes electron loss, maximizes conversion efficiency, and produces considerably higher power output over conventional panels.

Durability & Quality Assurance

N-type cells result in minimal Low Induced degradation (LID) and Potential Induced degradation (PID), which supports reliability and longevity. As a solar pioneer for over 40 years, Panasonic EVERVOLT solar panels are backed by innovation, experience and a brand you can trust.

Improved Performance When Shaded

Continuous power production in shaded areas for greater energy yields and output. More sunlight absorption means more clean power to your home.
