400 Watt solar panels

In this article, you will find the essential specifications of our most powerful and efficient 400 Watt solar panels. With the help of these highly productive modules, solar power can be collected anywhere in the world for many years and without any harm to the environment.

Advantages of 400 Watt solar panels

  • Excellent power output even in low light conditions.
  • Better efficiency thanks to half-cut cell configuration.
  • High efficiency at high temperatures.
  • Very-cost effective and price competitive.
  • Require fewer panels due to increased energy generation.
  • Reduced installation cost since requiring fewer panels.
  • Increased durability thanks to smaller cell size and therefore reduced probability of microcracking.
  • Low degradation rate.
