We compare Panasonic's EverVolt Solar Module Black Series models, EVPV410HK and EVPV400HK. These solar panels from Panasonic are designed with high efficiency, durability, and performance in mind. We compare the specifications of these two models and explain the significance of each specification to help you make an informed decision when choosing the right solar panel for your home or business.

Key Features

Both the EVPV410HK and EVPV400HK models boast several key features:

  • Heterojunction Cell Technology with Gapless Connections: This technology 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), supporting reliability and longevity.
  • High Efficiency in High Temperatures: EverVolt solar panels outperform others when temperatures rise due to their industry-leading 0.26%/°C temperature coefficient.
  • Improved Performance When Shaded: Continuous power production in shaded areas for greater energy yields and output.
