About product

A bifacial solar panel BiHiKu from Canadian Solar is perfectly suited for building high-output residential systems and large solar projects. Rear side of a BiHiKu provides up to 30% more power output, depending on the reflectivity of a surface.


  • 390W power output
  • Up to 30% more power from the rear side
  • 144 half-cut polycrystalline cells
  • up to 22.7% efficiency with the active backside
  • T4 series or H4 UTX or MC4-EVO2
  • 1500V or 1000V Maximum System Voltage

Rear side provides up to 30% more power

BiHiKu is a bifacial panel which means that both sides of a panel produce electricity under sunlight. The exact bonus that you get from the rear side of the module depends on the reflectivity of a surface behind a panel. It may reach up to 30% of the panel initial output which means that the basic module’s power output of 390W can go up to 507W maximum with 22.7% efficiency.

Half-cut cell design increases reliability and shading tolerance

Canadian Solar BiHiKu panel features half-cut cell design which increases the longevity, durability and shading tolerance of a panel. Hot spots are less likely to develop over the lifespan of a panel. The risk of microcracks is lower and their effect on the production is less significant. Besides, two sides of a module are independent from each other, therefore the shading of one half has no impact on the other one.

BiHiKu is ready for bad weather

Canadian Solar panels are known to do well even in low-light conditions. BiHiKu has a lower than average temperature coefficient of -0.64%/°C which makes it a good choice for hot areas as well. The panel can withstand heavy snow load up to 5400 Pa and wind load up to 3600 Pa.

Comes with strong warranties

The module comes protected by solid warranties from the Canadian manufacturer. The company provides a 12-year warranty on materials and workmanship plus a 30-year performance warranty.

So i bought this one. Since it’s a polycrystalline panel, it’s significantly cheaper and with a bifacial gain it’s a solid alternative to a simple mono panel in my opinion.
