About product

The HiKu module is a fresh addition to the Canadian Solar product line. It’s a high-output solar panel for commercial and industrial installations. 


  • 440W power output
  • 19.9% efficiency
  • 144 half-cut cells
  • MC4 connectors
  • 1000V or 1500V max. system voltage

High efficiency allows to build powerful systems

The HiKu panel provides a great 440W power output with 19.9% efficiency which is better than average numbers on the market. High conversion rate allows you to build powerful installations with less space and less modules. 

Half-cut design increases durability and shading tolerance

The new Canadian Solar panel has 144 half-cut cells which makes it slightly larger than 60/120-cell panels and makes it more suitable for commercial projects. Half-cut cell design makes the panel sturdier and less susceptible to microcracks. What is more, it increases the shading tolerance of a panel, because the panel is split in two halves. It’s like having two small panels that are wired in parallel.

The panel is ready for bad weather

Canadian Solar panels are made to perform well in bad weather. They have always been doing well in low-light conditions, like on cloudy days and in the winter and the fall. At the same time they are durable enough to withstand heavy snow load up to 5400 Pa and wind load up to 3600 Pa.

Comes protected by warranties

The HiKu is accompanied by rather standard, but still nice warranties from Canadian Solar. The panel comes with a 12-year warranty on materials and workmanship and a 25-year performance warranty.

I have had these for two months and so far, I'm very happy. The change in performance on cloudy days is noticeable, but still much better than it is with my neighbor's panels!

Got my panels, everything’s in good shape. Very happy with the service and all the advice I got from you. As for the panels, we’ll see how they do!

Hi We’ve ordered a batch of these panels for our shop in Oregon. Even though it can get pretty cloudy here, the panels are doing fine. This is actually why I chose CS, because their panels are known to be good in bad weather. The service was excellent and i’m here just to thank you, peace

How much is shipping and how long is delivery?
Our standard shipping charge is $250 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
