About product

Canadian Solar KuMax monocrystalline module offers 380W power output with 19.15% efficiency. The panel has improved shading tolerance and power losses in cell connection are low. The 380W 144 Cell solar panel is a good choice for both residential and commercial installations.

Features:

  • Power output: 380W
  • Efficiency: 19.15%
  • 3 bypass diodes
  • T4 connectors
  • 25 linear performance warranty, 10 year product warranty

High efficiency up to 19.15%

The 380W module offers 19.15% efficiency. High energy conversion rate allows you to build a powerful system with fewer panels. It is especially important when the space is limited: on a boat, RV or a small roof.

A reliable and long-lasting purchase

The design of Canadian Solar panels lowered the risk of microcracks and hot spots. The module withstands heavy snow load up to 5400 Pa, wind load up to 3600 Pa. The frame is made from anodized aluminium.


25 year warranty for performance

Canadian Solar offers a 25 year warranty for linear performance of their product. The panel also comes with a 10 year product warranty.

Improved shading tolerance and performance at high temperatures

Every KuMax module has three bypass diodes which decrease the impact of shading on performance. What is more, the temperature coefficient (Pmax) is at -0.37 % / °C, which means that the panel works very well in hot areas.

The design might not seem like much, but panels are good. I’ve checked. They barely drop watts even on a dark day.

So impressed with how these panels work on cloudy days! Here in Washington there is frankly not a whole lotta sun, but i still get a nice harvest of it every day. Gotta say, Canadian solar rules

You will need mounting hardware, see sunmodo.com for solution
I’m building a tinny home 330sq ft, how many panels would I need to power the whole tinny home What other components do I need

You need to estimate your energy usage to figure out an exact number. You will need racking, cables, batteries, charger controller, inverter .
On the dimensions listed, 78.7" x 39.1" x 0.23".... are these really less than 1/4” thick or is this a misprint? I see that they are not frameless. Are they really in a frame that is less than 1/4” thick. If that is not correct, how thick (or deep) is the frame?

There is an option for frame-less but we only have 35mm frame in stock right now.
Are these frameless?

No.
Can the 48 volt panel be used for a 12v system on a boat? Thanks.

A1SolarStore
yes as long as boat charge controller can handle the this much power.
Could these be mounted on the roof of RV? Would they have to be angled or can they lay flat?

yes you ca mount them on to the roof of the RV. I think flat would be a universal solution.
Does this panel fold in half

FAQ

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
