About product

Canadian Solar 320W Solar Panel 60 cell CS1H-320MS-Black

With Canadian Solar’s industry leading mono-PERC cell technology and the innovative LIC (Low Internal Current) module technology, we are now able to offer our global customers high power mono modules up to 320 W. The KuPower mono modules with a dimension of 1700 ˣ992 ˣ35 mm, close to our 60 cell SuperPower modules, have the design that provides a great appearance and less shadow effect. These modules with their high wattage, appealing aesthetics, and good shading tolerance, are one of the best choices for rooftop systems where space may be limited and shadowing is unavoidable.

Main Features

  • High module efficiency up to 18.98 %
  • Lower internal current and hot spot temperature risk
  • Lower micro crack risk due to shingle cell design
  • Low temperature coefficient (Pmax): -0.37%/°C
  • Low power loss in cell connection
  • Better shading tolerance
  • More power output thanks to low NMOT (Nominal Module Operating Temperature): 43 ± 3°C

Working with A1Solar was a great experience. All the questions I had were answered quickly, they help me set up delivery, and before I knew it, I had my modules. Thank you!

These were recommended by the installer we were working with. Quality panels for not a lot of money. So far they've been performing very well.

We only considered two brands of solar panels before buying. This one appeared to be much better when compared by price and efficiency.

I do not know a lot about solar panels to compare them but I do know that these panels are working great for me. I had no issues at all after installing these modules.

I wanted nice black panels that could blend with my roof. I like that these modules do not have extra frames that stick out. Just a clean look I was searching for.

The modules generate great output even in overcast weather. Exceeded all my expectations!

Can this panel be used with a 12v system?
Can this panel be used with a 12v system?

Yes it can be, just make sure you charge controller can handle it.
Does it work for home at 110 voltage at Texas USA? Can it connected to the grid? Is it with enphase converter ?
06/12/2020, 12:50
Its just a single panel, no inverter or anything else. You need to build a system to connect to the grid.
Do you ship 7000 watts to Puerto Rico?

We can ship to freight forwarder.
I want to connect 10 of these to a solaredge 3800 inverter , do I need optimisors on each panel ? 480-440-0572 smithtanar@yahoo.com

only if you have shading problem
Can I pick up a panel at your warehouse in Florida? I live in Naples and can drive to Fort Myers, Fort Lauderdale or Miami.

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
