About product

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

Features:

  • 445W power output
  • 144 half-cut monocrystalline cells
  • up to 25.9% efficiency
  • T4 series or H4 UTX or T4 series or MC4-EVO2 connectors
  • 1500V 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 output of a module increases from 445W to 579W maximum with 25.9% efficiency.

Half-cut cell design increases reliability and shading tolerance

Canadian Solar 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 -0.34%/°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. The 1st year power degradation doesn’t exceed 2% and subsequent annual power degradation is no more than 0.45%.

Certainly a good investment in the long run. Here in Arizona each panel gives me about 500W of power or so, depending on the day. Loads of power, I don't actually feel like I need the grid anymore.

We’ve used these panels for over half a year on our farm in Colorado. They are very strong. I don't feel like the rear side adds a lot but it’s more like my fault though, I should figure a way to make sunlight bounce off the roof, but I haven't been able to get to it yet.

Can I use them for my boat?
You can, but it might be hard to install them in a way that allows you to benefit from the active rear side.
i wonder, how thick is the glass? Does the backside also have glass or is it just a clear backsheet?
It’s a dual-glass module, yes. The thickness of the glass is 2 mm.

FAQ

How much is shipping and how long is delivery?
Our standard shipping charge is $195 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
