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.

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.

Jose

A1 SolarStore

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

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?
